Picture of The Official Guide to Knex Ball Machine Lifts
Ever since Wipe Out, people have been interested in building new lifts for Knex ball machines, so I made this guide!

This guide will include all of the ball machine lifts that have been built. In each step is a short description of the lift, a credit to the builder, and links to instructions/videos. If a lift includes at least one picture it'll either be added into an existing step or made into a new step. If a lift includes no pictures, but only a video, it will be added to the second to last step, titled "Lifts Without Pictures". This is to make the guide official, instead of only including lifts with pictures.

If you want your lift added or know of another lift to be added, just post a comment below with links/pictures. Please have good quality pictures, not ones that are blurry, fuzzy, dark, etc. Every builder is credited to their lift, usually with a hyperlink to their profile, but if you don't want your lift on this guide due to copyright reasons, just tell me and I'll take it off of the guide.

Please tell me if you have any suggestions or feedback for this guide. I hope you find it useful!

This guide started out with only 10 steps, but now it has over 70! The search bar below allows you to search steps by title, just in case you can't find a lift within the huge mass of steps. Thanks to Sorunome for programming it. :-)

Step 1: Chain Lift

Picture of Chain Lift
This lift has been around since ball machines began because of the Big Ball Factory. It's an easy lift to build, and doesn't require much pieces. You just don't want the chain too loose or too tight. Adjusting the chain is simple; just add another set of gears somewhere on the back of the tower. Refer to the third picture for an example of that.

If you're wondering what Disco Track is, it's my younger brother's ball machine (he's also a Knexer, his name on 'Ibles is Jag56).

Step 2: Micro Chain Lift

Picture of Micro Chain Lift
This is a chain lift made out of micro chain, and the ball holder is also made of micro pieces. The pictures below are from mathsboy314. The last picture is from here, made by rymndgeekyguy.

Step 3: Chain Path Lift

This lift combines a chain lift with a chain path element. The base is the same as a normal chain lift, and it still goes up vertically. The difference is that the claw that holds the ball doesn't have anything to push it out when it gets to the top. The chain is run along the top, and the ball rolls across it like a chain path. The ball then falls into a basket when it gets to the end. Watch a video of it right here.

Most of the pictures below show it in Cataclysm during the construction.

Step 4: Alternative Chain Lift

Picture of Alternative Chain Lift
This lift was invented and built by floris2burn. This is a lot like a vertical chain lift, except it can go diagonal or horizontal. It also has a different ball claw. The unique thing about it is that the gears can be connected to the tower differently, allowing the ball claw to pass through the middle of the gears (picture 6 shows this). He used it in his ball machine, Cyclo. Click here for the instructions!

Step 5: Semi-Circle Lift

Picture of Semi-Circle Lift
This is a lift built by Tornado96. It is similar to a chain lift, except the chain runs along a guide that is a semi-circle. Here are the instructions! 

Sorunome built a larger version for his ball machine Dystopia, in the third picture.

Step 6: Chainsaw Lift

Picture of Chainsaw Lift
This lift uses chain, which is on a track leading diagonally upward. I call it the chainsaw lift because the things sticking out of the chain that pick up the balls make it look like a chainsaw. This was featured in Cataclysm; pictures are below.

A similar lift was also in Loopy, built by I_am_Canadian (last picture).

Step 7: Inverted Chainsaw Lift

Picture of Inverted Chainsaw Lift
This is similar to the regular chainsaw lift, except the ball is pushed along a track, with the chain on the top! Sorunome built this lift, which has pictures below. Notice that the ball touches the ground at the bottom.

Step 8: Vertical Chainsaw Lift

Picture of Vertical Chainsaw Lift
This lift was built by shadowninja31. It's like an inverted chainsaw lift, except it's tilted vertical, similar to a normal chain lift. He used this in his small ball machine. Pictures are below.

Step 9: Ultimate Chainsaw Lift

Picture of Ultimate Chainsaw Lift
Built by Sorunome, this lift is a chainsaw lift that combines all of the previous types: normal, vertical, and inverted. This lift was built for his ball machine, Apocalypse

Step 10: Stair Lift

Picture of Stair Lift
I first used this small lift in Wipe Out. The steps go up and down, all at different heights. You can make it higher with more steps, but I wouldn't go over 5-6 steps. If you need it higher than that, you'll have to use more than one motor.

If you want to build it, here's the Instructable.

Step 11: Stair-Arm Lift

Picture of Stair-Arm Lift
This lift is similar to a stair lift, except it uses arms instead of platforms. Since they don't slide on rods, there isn't as much friction, so this stair lift can be made much taller than the original stair lift. It also slants 45° (the old one slants half as much), so it can be made taller in a shorter amount of space. The arms do take up more room though. If it uses an odd number of arms (like the version in Citadel), one of the arms needs a counterweight, shown in picture 3. 

Currently, this lift is in my ball machine Citadel, which is still under construction. Click here for the update video that shows this lift working. I am going to make instructions of this lift, but until then the pictures above are from Citadel's construction album.

Step 12: Double Helix Lift

Picture of Double Helix Lift
This lift was also used in Wipe Out. The helices are made out of tubing, so the ball's ride up the lift is pretty smooth. I wouldn't make it too high because the double helix will become wiggly. 

Click here for the instructions!

Step 13: Single Helix Lift

Also known as spiral lifts, these are similar to my double helix lift, except they only have one spiral instead of two. There was a Knex set that used a spiral lift in it, and the instructions are here. The video is here.

KageKumo used a diagonal spiral lift in his ball machine, and the video is here.

Above are pictures of my double helix lift, changed into a single helix lift. Thanks to Sorunome for the pictures. Also included are pictures of a tilted helix lift, built by mathsboy314. His helix is basically a helix from Trampoline Tower. The last pictures 4-6 show it, and here is a video.

Tornado96 made a slightly different helix lift in his ball machine Uprising (picture 7). The helix part was built to be stronger.

Step 14: Inverted Helix Lift

This is similar to the helix lift, except it's inverted (it's also known as inverted double helix lift). Instead of the helix spinning in the center, the tower spins in the center, with the helix outside. This lift is much more efficient than the traditional single/double helix lift, because it can be made taller, since the tower in the middle is stronger than a helix. And, it's more fun to watch because the balls spin around as they go up. :-) The tower in the center of mine had two sides for balls, but I could have made it a quadruple helix lift since it has 4 sides. Here are the instructions

This lift was featured in Cataclysm, and there are pictures of it above (pictures 5-10).

Also, it's possible to use twice as less tubing/orange-tabbed connectors if you only build the bottom strand of tubing and leave out the top strand. Pictures 11-12 below show this version. The one in picture 11 was built by Sorunome, and the one in picture 12 was built by Koolcoasterkid (this picture is only the top view). Click here for more information about this method, since there are a few things you'll have to modify.

Here is a video of this lift:

Step 15: Tower Helix Lift

Picture of Tower Helix Lift
This lift was built by Sorunome. It's similar to a regular helix lift but the tower around the helix spins, and the helix is stationary. 

This lift was featured on Sorunome's ball machine Catastropha. The video is below.

Step 16: Shredder Lift

Picture of Shredder Lift
This lift was made by Lego Andrew. It uses the same concept as a helix lift, except there are separate rods that push the ball up. The rods are made in a spiral pattern. The video is below and the instructions are here. Note: This lift may be unreliable and require modification.

Step 17: Hopper Lift

Picture of Hopper Lift
Built by Mr. Muggle, this is a lift that can be extended. It uses arms that turn around, and a curved track that the ball rolls on. All of the arms are connected with chain, and they move in the same direction.

Thanks to Mr. Muggle for the pictures!

Step 18: Singular Arm Lift

Picture of Singular Arm Lift
This lift was built by Purple Waffles. It is similar to the hopper lift, because it has one arm that lifts the ball up a curved track. A counterweight on the other end helps it lift the ball. A picture is below.

Step 19: Motorized Madness Circle Lift

Picture of Motorized Madness Circle Lift
Built by sathothy, this lift uses motorized madness track and small arms in the middle. The arms rotate, and the track is placed so the ball fits in between. Here are the instructions

Step 20: Rotating Arm Lift

Picture of Rotating Arm Lift
There are many versions of rotating arm lifts that people have built. This step will go through many of the different versions.

The most basic rotating arm lifts use a carrier at the end of rotating arms to lift balls up. An example would be the version in Picture 1, built by sandroknexmaster. This version doesn't use track at the bottom; instead it picks balls up from the floor directly. Instructions of this lift are located here. Another example of a basic rotating arm lift is one made by collinjo12, what he calls a modified arm lift. The instructions are here, and his lift is Picture 2. Below is a video of Sandro's lift.


Another type of rotating arm lift was built by MechanicalCreationMaster (it's also called Freefall Wheel Lift) in Krypton. It uses a thin arm to lift balls up a curved track, and when the ball gets high enough it goes toward the center of the arm. Then some track makes it lift up higher. These arms have no carriers like the more basic versions, but it causes the movement of the arm to be choppy at times. Picture 3 shows this lift.

There is another version similar to MCM's lift, built by sandroknexmaster for his ball machine Paradox (4th picture). Below is the video of Sandro's lift, and here are the instructions!

Step 21: Large Rotating Arm Lift

Picture of Large Rotating Arm Lift
This one was featured in Wipe Out. It's a big arm that spins around and around. Before the balls get to go up in it, they wait at a rotating gate which turns at the exact same speed as the arm. This helps to not have lots of balls crowded at the bottom where the arm picks them up.

I don't have much good pictures of this lift. The best place to see this lift is in Wipe Out's video.

smool also made a rotating arm lift in his ball machine, SmooL. Click here for the instructions on his lift! It's a lot like mine, with a similar gate system. It uses less pieces than mine and has a different way of dispensing the balls at the top.

Step 22: Quadruple Rotating Arm Lift

These lifts are similar to normal rotating arm lifts, but they use 4 arms instead of 2.

The earliest version of this lift type was built by I_am_Canadian. It has four arms that each pick up balls, and carriers similar to standard rotating arm lifts. You can stack them up to make the lift higher. This lift is one of the earliest custom lifts built.

Thanks to IaC for the instructions, pictures, and video. Pictures 1-3 show his lift.

A later version of this lift was built by Kairah, and featured in Metropolis. This is an example of several arm lifts stacked onto each other, and they use chain to connect them to one motor. Pictures 4-7 show his lift. Here are the instructions!

Step 23: Wheel Lift

Picture of Wheel Lift
There are many wheel lifts, and the first version built was a small one first featured in Cataclysm (pictures below). Click here to see a video of it. Sorunome made instructions of it here (it is slightly different from the original; see Picture 3). When you build a wheel lift, you'll need to pay attention to the entrance. Either make a gate that lets the balls in slowly enough or make the balls load in from the side. Go to the next step for an example of balls loading into the side.

Mr. Muggle built one in his ball machine, Shake (Picture 4). Instructions for that ball machine, including the lift, are here.

There's also one in KageKumo's ball machine. There aren't pictures, but the video is here. This is an example of many wheels stacked on top of each other.

Coaster105 used a rather large wheel lift in his ball machine. The video is here.

toeti built one (picture 5) in his ball machine Nemesis. The instructions are here.

Another example is shown in Picture 6, built by sandroknexmaster. Here are the instructions of his version.

Step 24: Small Wheel Lift

This lift is very similar to the one I used in Cataclysm, except it's shorter than two red rods in diameter (instead it's at most 3 blue rods in diameter). I built the first version of this lift in my unfinished ball machine. Pictures 7 and 8 show it at an earlier point in the ball machine's construction.

Picture 9 shows a lift built by Sorunome, which classifies as a small wheel lift. This was in his ball machine Dystopia, which was built after my first version of the small wheel lift. It's different than the original though, since it doesn't use tubing and the wheel is built differently. The instructions can be found here.

In Citadel, I rebuilt this lift and improved it, like making it not use tubing, and making the wheel look better. There are 3 stacked up, and they use flexi-rods covered in blue spacers (silver spacers would also work). I don't have a video of these yet, since the ball machine is still under construction. Pictures 1-6 above are from Citadel's construction album (pictures 4-6 show the lift section before it was added to the ball machine).

Step 25: Tiny Wheel Lift

Picture of Tiny Wheel Lift
First featured in Citadel, this lift is the smallest a wheel lift can get, so small that it doesn't really resemble a wheel. It uses these small wheels and has them stacked up. The larger wheel lifts use a track with two rods/strands of tubing, but this one uses one. With the way I have it built it uses two medium yellow gears, so it isn't very ideal to make it very tall unless you use chain or different gearing. This lift is best when it's a red rod to two red rods tall, and it fits in small spaces nicely.

Currently, this lift is in my ball machine Citadel, which is still under construction. Click here for the update video that shows this lift working. The picture above is from Citadel's construction album.

Step 26: Wheel Lift with Holes

Picture of Wheel Lift with Holes
This is another lift used in Wipe Out. It's a wheel where the balls load in holes in the side. As it turns, balls enter in one side and leave on the other side when they get to the top. The trick of the balls leaving at the top is that the wheel is tilted. The ball can also exit if the hole the ball is in has tilted track to make it leave at the top.

Again, I don't have much pictures of this lift, since it was taken with my old camera.

Another small wheel lift which uses a similar method is the one used in wanny's ball machine, Davinch. Watch the video here.

Sorunome built one of these also (picture 3), and made instructions. Here's the video.

Picture 4 shows sathothy's wheel lift, built with micro pieces. It was featured in his ball machine, Armageddon.

KneXtreme built a wheel lift that is thinner, and a piece at the top pushes the balls out, shown in picture 5. Here are instructions!

Step 27: Large Wheel Lift with Holes

Picture of Large Wheel Lift with Holes
This lift is similar to the lift in the previous step, except it's bigger. Sorunome made instructions for the lift pictured below.

Step 28: Ring Lift

This is a lift that was featured in Cataclysm. It is a wheel, without a center, thus calling it the ring lift. It takes up less room than a normal wheel lift, since it has no center. It has to be secured into a strong tower structure for it to run as smoothly as mine did. Chain runs around the outside and grips the wheel, and a motor at the bottom turns the chain.

Below are pictures of the ring lift used in Cataclysm. The ring is pretty thin, as you can see in the fifth picture. Picture 8 shows where the balls enter, and the picture after shows where they exit.

Sorunome recreated this lift from Cataclysm's video, and made instructions! The last picture shows it.

Step 29: Spiral Wheel Lift

Picture of Spiral Wheel Lift
This lift was built by bezempje95. It's a wheel that turns, and a spiral track is on the inside. The balls go up until they reach the center, where they exit the wheel. There are pictures below, but no instructions/video.

There is another version of a spiral wheel lift, made by KneXtreme (starting at the 5th picture). It's smaller than bezempje's and uses regular tubing track instead of roller coaster track. Click here for the video and here for the instructions!

Step 30: Revolving Ball Machine Lift

Picture of Revolving Ball Machine Lift
Built by mathsboy314, this lift was originally built in the form of a revolving ball machine, but can also be used as a lift or element. It uses a large wheel with elements inside of it. There are many different possibilities with this lift. Click here for the video of the lift version and here for instructions.

Step 31: Mouse Wheel Lift

Picture of Mouse Wheel Lift
This is a lift created by TheFoofinator. It's made of a wheel with scoops on the inside to pick up the balls and drop them off at the top.

Click here for instructions!

Step 32: Spinning Freefall Lift

Picture of Spinning Freefall Lift
Built by sandroknexmaster, this lift rotates like an arm, but it's a freefall also. So, when the ball gets to the top, it freefalls to the bottom and is lifted up again on the other side of the freefall. A gate is used at the bottom to allow only one ball to go through the entrance. The instructions are here.

Step 33: Large Arm Lift

This is a lift featured in Cataclysm. Instead of it rotating around, it goes up and down. There's a CyberKnex motor on the arm's tip, and it's lifted by reeling in fishing line. The ball pushes a button on the tip of the arm in order for this to happen. When the ball leaves at the top, it pushes switches (including another motor) to reset everything. This lift uses a lot of pieces, but it's worth it. The last two pictures show the gate at the bottom that lets one ball in at a time.

See Cataclysm's video to see it finished! The video below shows it finished, but without the gate at the bottom.

Step 34: Quarter Arm Lift

Picture of Quarter Arm Lift
This quarter arm lift was built by CassisDude98. The arm uses a crank to go up and down about 90 degrees. Here are instructions, made by KneXtreme. The arm lift in those instructions is slightly modified from the original. 

There is a different version of a quarter arm lift made by Palslayers. Here is the video of his version.

Step 35: Parallel Arm Lift

Picture of Parallel Arm Lift
This lift was originally built in my unfinished ball machine (skip to 4:47 on the video to see the lift). It uses arms that are parallel, and they are connected in the back. Balls roll down the arm into a claw, and, when the arms get to the top, the ball goes through a flap in the bottom of the next arm. My version didn't work very well, since there was a lot of strain when it was fully loaded with balls. It was also pretty slow. 

Sorunome rebuilt it from the video and modified it to make instructions, shown in picture 6.

Step 36: Counter Parallel Arm Lift

Picture of Counter Parallel Arm Lift
This lift was built by sandroknexmaster, and was first featured in his ball machine Euphoria.The arms are similar to a regular parallel arm lift, but there are two sides of arms instead of one. A crank at the top alternates both sides (when one is up, the other is down).  Here are the instructions, and the video is below.


Step 37: Connected Arm Lift

Picture of Connected Arm Lift
Built by sandroknexmaster, this lift uses two sets of connected arms that alternate with a crank. It was first featured in his ball machine Euphoria. Here are instructions!

Step 38: Crossing Arm Lift

Picture of Crossing Arm Lift
Made by mathsboy314, this lift is an arm that goes up and down using a crank. The end picks up a ball, and when the arm is tilted enough, the ball rolls along the top of the arm and off of the end. Here are the instructions!

Step 39: Falling Arm Lift

Picture of Falling Arm Lift
Built by sandroknexmaster, this lift uses a crank to lift an arm up, and the arm falls down fast. The arm uses an upper joint to make the ball exit at the top. Click here for the instructions!

Step 40: Shifting Arm Lift

Picture of Shifting Arm Lift
This lift is a collaboration between me and Tornado96. It uses two sets of arms that alternate on going up and down. The balls are shifted from one side to the other when the arms move. It uses a double crank at the bottom and a gate system to keep the balls in the lift.


The video is embedded below.

Sorunome built a shifting arm lift for his ball machine, Apocalypse, shown in picture 5. His version is 8 arms tall. Picture 6 shows one built by koolcoasterkid, which is 6 arms tall. These two versions had to be modified in different ways to make them work, more information on that can be found here.

Step 41: Multiple Arm Lift

Picture of Multiple Arm Lift
This is a lift built by mathsboy314. The arms have different widths to allow one arm to go inside of the other. A wave motion makes the arms go at the right timing to hand the ball from one arm to the next. Here are the instructions! 

Step 42: Right-Handed Arm Lift

Picture of Right-Handed Arm Lift
Built by dickheijboer, this lift uses arms that are lined up with each other, much like the multiple arm lift, except this lift is built differently and has more arms. Below is the video, and here are the instructions!

Step 43: Small Returning Arm Lift

Picture of Small Returning Arm Lift
Built by KneXtreme, this lift uses arms that go up and down that hand each other the ball. Each arm rotates about 180 degrees. Here are the instructions!

Step 44: Jigsaw Lift

This lift was originally invented by bezempje95, but he deleted his account and instructions; Sorunome decided to post his version, so now there are instruction again. With this lift there is a shaft, tilted diagonally, which has something in the middle that goes up and down in a circular motion. The part in the middle has "spikes" on it, that grip the balls and take them up a level. There is also a counterweight. Pictures 1-6 above show Sorunome's version (5 and 6 show the lift in Apocalypse), and pictures 7-9 show bezempje95's. Click here for the instructions!

Step 45: Vertical Jigsaw Lift

Picture of Vertical Jigsaw Lift
This lift was invented by Tornado96 as a prototype. I built upon his original idea and made the exit track and motor connection for my ball machine, Citadel. The first picture shows the final version. There is also a counterweight to assist the motor in moving the jigsaw part up. 

Click here for the update video that shows this lift working. I am going to make instructions for this lift, but until then the picture above is from Citadel's construction album.

There is also a different version of this lift, made by mathsboy314. He calls it a puzzle lift. Here are instructions and the video!

Step 46: Ladder Lift

Picture of Ladder Lift
This is a lift built by Thibault Art. It is a bit similar to jigsaw lifts, except the balls go inside of the rotating carrier instead of along the side, which is where it gets the name "Ladder Lift". It is also different in the way the balls are stored for each rotation, inside of the tower structure itself. Here are the instructions.

Step 47: Mill Lift

These are two different lifts invented and built by Kairah and floris2burn (the original inventor of this lift). They are both similar to each other, which is why they're both called mill lifts. Floris2burn's uses wheels that have two spokes sticking out to lift up the ball up a diagonal slope. Kairah's is made of wheels with 4 spokes, and the advantage it has over the other is that it can go diagonal, horizontal, and vertical, or even upside down. It's also smaller than floris2burn's. He also made a second version, which is built into a tower. It works 100%, and goes much faster! Watch the video down below. More balls can be added to it, but the more balls it lifts at a time the more strength it needs.

Click here for instructions of floris2burn's mill lift!

The first 4 pictures were taken by foris2burn of his lift. You can find the video here.

Here's the video of Kairah's mill lift:

Here's Kairah's second version of his mill lift:

Step 48: Wheel/Mill Lift

Picture of Wheel/Mill Lift
This lift was built by Kairah. It is similar to the mill lift he built in the previous step, except the wheels are modified to let less balls in at a time. This lift was featured in his ball machine, Metropolis. Here are the instructions!

Step 49: Twin Elevator Lift

This is an elevator lift that was first built in Citadel. It uses two carts to lift the balls, each one carrying 4 balls. Since the carts weigh the same they act as each other's counterweight. It uses a simple forward/reverse transmission to make them switch direction (the gearbox is located in the base). The video below shows all of the parts working. There are two reels of fishing line, and the reels are easy to adjust, which helps to combat stretching of the fishing line.

Right now Citadel is in construction, so the pictures above are from the construction album. (Pictures 1-11)

In addition to my elevator lift, there is also a similar version built by dickheijboer. It uses the same concept of a twin elevator lift, but it is less refined than mine, so it isn't as smooth. The transmission box is at the top, and uses bits on the chain to switch direction. This is a nice lift to use as an alternative to mine if you don't have very many pieces, as this one uses less pieces. It also has a nice speed and runs pretty smoothly. Between choosing which twin elevator lift to build, the one I made has a more refined system, as well as taking 4 balls up at a time instead of 3. But, if you need to save pieces and build a simpler version, you can build this one, as it still works nicely. This lift was first featured in dickheijboer's ball machine Intertwined, and the instructions for the lift are here. The pictures of his lift begin at Pic. 12, and the video is below.

Step 50: Elevator Lift

This is an elevator lift built by Sorunome. It uses an elevator cart that holds 8 balls and a counterweight. The up and down motion is controlled by a gearbox that has forward and reverse transmission, similar to the twin elevator lift. Levers switch the gearbox when the elevator gets to the top/bottom. In total, the lift uses 34 gears. This lift is featured in Apocalypse, and below is a video of the lift.

Step 51: Elevator Free-fall Lift

Picture of Elevator Free-fall Lift
Built by KneXtreme, this lift is an elevator lift where the cart that holds the ball falls straight down when it gets to the top. String is attached to the cart, and a special gear with some teeth cut out spins a reel to lift the cart up. Here are instructions!

Step 52: Wheeled Crankshaft Lift

Picture of Wheeled Crankshaft Lift
Built by mathsboy314, this lift uses a large crank to lift a platform up and down along a track. It's much like a crankavator since it's an elevator powered by a large crank, instead of a gearbox. The track is used so the platform can have wheels, instead of sliding on rods. Here are the instructions!

Step 53: Pump Lift

Picture of Pump Lift
This is a lift built by Sorunome. It consists of a chute, and the balls are pumped up by a mechanism at the bottom. A gate keeps the balls from falling back down. There is a piston that moves from side to side, which pushes the balls upward. This lift can be a problem if you don't have a lot of balls, because you can only make it as high as how many balls you have.

Here are the instructions!

Step 54: Stacker Lift

Picture of Stacker Lift
This lift was built by bezempje95. It is similar to a pump lift because it stacks balls on top of each other in a chute. But, there is a wheel at the bottom that lifts balls one by one, so it's much more simple. There is also a rod that keeps the balls from falling back down. Here is a video. Also, he built a ball machine using this lift, called Gravity.

Step 55: Big Air Ball Tower Lift

Picture of Big Air Ball Tower Lift
This is the air motor and tube lift from the Knex set Big Air Ball Tower. It only works with the newer balls, and it requires two balls in order to lift one ball through the tube. This is one of the fastest Knex lifts, as far as how long it takes for a ball to reach from bottom to top. Thanks to Sorunome for taking pictures of this lift.

Step 56: Scissor Lift

Picture of Scissor Lift
This lift was built by Sorunome. A platform that carries balls lifts up, letting them out the top. It's a bit slow, but it can fit multiple balls on the platform. You can modify it to make it go higher. Here's the instructions!

Step 57: Door Lift

Picture of Door Lift
Built by martijnb95, this lift uses a wall that goes back and forth with a crank. The balls are lifted on doors that open up and close as the wall pushes the balls. Here are instructions!

Step 58: Push Lift

Picture of Push Lift
This lift was built by sandroknexmaster. It uses a vertical crankshaft to alternate two sets of pushers. There's also a gate that releases the balls evenly into the lift. Click here for the instructions!

Step 59: Stepper Lift

Picture of Stepper Lift
This lift was in a Knex set. There are two sides which move up and down, and the ball is switched back and forth between the two sides as it goes up. A video is right here (not my video).

I haven't built this lift yet, so I don't have any of my own pictures. Thanks to I_am_Canadian for the pictures, which are of his ball machine, Twister.

Instructions are right here. This is a step within an Instructable for Retrograde (designed by MarsCrystalMan and instructions made by knexpert#10829476.

Step 60: Up and Down Lift

Picture of Up and Down Lift
This is a variation of the stepper lift built by dickheijboer. Unlike the stepper lift it fits into red rod scale, which is useful since that's the standard for most ball machines. It also uses a different way of making the balls exit the carts. Here are the instructions!

Step 61: Modified Stepper Lift

Picture of Modified Stepper Lift
This lift is similar to the lift in the previous step, except the carts that carry the balls don't slide on rods. Instead, they are connected with small towers that move on axles. This allows for less friction, so you can make this lift as high as you want.

This was originally built in Unfinished Knex ball machine. You can see this in the 5th picture.

Here are the instructions! Below is the video.

There is a different version of this lift, made by Thibaultisthebest. collinjo12 made instructions here. His version uses less pieces than mine, but its movement is pretty choppy. The last picture shows his lift. 

Step 62: Modified Chain Stepper Lift

Picture of Modified Chain Stepper Lift
This lift was built by KneXtreme. In this lift, the steppers are on small towers that slide up and down on wheels, and chain controls the movement. Here are instructions, and below is the video.

Step 63: Alternating Arm Lift

Picture of Alternating Arm Lift
This lift was built by me and Tornado96. It uses concepts from the alternator lift and stepper lift. The arms go up and down on opposite sides, and the ball holders flip up when a ball is arriving underneath. Here are the instructions, and below is the video.

Step 64: Alternator Lift

In this lift, there's a tower in the middle that goes up and down (the lifter). Grabbers on the lifter grab the balls and lift them to the top. Ball holders keep the balls from going back down. A crank turned by a motor makes the lifter go up and down. The balls alternate from one side to the other, which is why I called it the alternator lift.

This lift is featured in Cataclysm. The last few pictures show it.

Here's the video:

Step 65: Slider Lift

Picture of Slider Lift
Built by mathsboy314, this lift is similar to the alternator lift, except it's tilted and uses less pieces. A crank makes a sliding platform go up and down, and balls get stopped by small arms in the tower. It can be modified to go higher easily, but keep in mind that it gets more choppy under the load of a lot of balls. Here is the Instructable!

Step 66: Rollerball Lift

Picture of Rollerball Lift
This lift is made of a roller coaster car and track, and the car has a bucket that holds the ball. The ball falls in the bucket and is lifted up the chain lift on the lift hill.
This was first used in RCManiac31's ball machine, Mission to Mars.

Mr. Muggle recreated the lift section (pictures below) and used it in his ball machine, Power Tower.

Step 67: Micro Rollerball Lift

Picture of Micro Rollerball Lift
This lift is similar to the rollerball lift, except it uses micro-style roller coaster track. The car pushes the ball to the top, and the car is pulled up with a chain lift. mathsboy314 made this lift, and took pictures which are below. He also made instructions, and below is the video. His version uses micro pieces for the support tower, but you can use standard pieces if you want to.

Step 68: Car Lift

Picture of Car Lift
This lift was built by therealkeggore (also known as Keggore) in this ball machine. Balls are carried by cars, which go around a continuous track, and part of it slopes up so the cars can get to the top. The ball gets out of the car by the cart it's in being tipped over. The cars are able to go back down much faster.

KneXtreme also made instructions of this lift in his ball machine, Lithium (pictures below). The lift in the instructions is slightly modified from the original.

Step 69: Hammer Lift

Picture of Hammer Lift
This is a lift built by RNB. In this lift, a rotating arm goes up, and it comes down real fast, sending the ball up the incline.

Here are the instructions!

Here is the video:

Step 70: Kick Lift

Picture of Kick Lift
Built by knexcrazzzzzy, this lift is similar to the Hammer Lift, except it is more powerful. Below is the video.

Step 71: Ball Launcher

This lift launches the ball with the use of two wheels. The motors, battery pack, switch, and wheels were taken out of a Rippin' Rocket power booster. Silver spacers are placed around the edge of the wheels, and they're taped over with a layer of clear tape and electrical tape. Rubber bands on the outside of the wheels add grip and power.

I pictured earlier designs, and the newest ones. Picture 8 shows a track system that didn't work very well, but I improved it by making the track lead straight up (pictures 4-6). Picture 3 shows a close-up of the switch.

Step 72: Micro Ball Launcher

Picture of Micro Ball Launcher
This is a lift made by tornado96. It's a lot like my ball launcher lift in the previous step, except it uses the power booster found in the Lava Launch coaster.

Step 73: Launching Arm Lift

Picture of Launching Arm Lift
This lift is was built by Austron. You can find the blog post here. This lift is a bit similar to the hammer lift, except the arm that launches the ball doesn't go all the way around. The arm's power comes from a rubber band. There is a series of gears that makes everything be powered by one motor, including a small arm that deposits the balls into the launching chute. Below are pictures. The video can be found at the link to his blog post above.

Step 74: Ball Launcher/Shooter

Picture of Ball Launcher/Shooter
This lift was built by bezempje95. It's almost like a catapult mechanism, and it launches newer Knex balls. It uses two motors to power it. Pictures are below, and here are the instructions! He used this lift in his ball machine, Ejection.

Step 75: Jump Lift

Picture of Jump Lift
This is another type of launching lift, built by sandroknexmaster. It is quite small, so it can fit underneath floors easily. Keep in mind that the lift will push the line of balls in the entrance track back a bit, so you won't want too many balls lined up there. Here are the instructions!

Step 76: Jump Arm Lift

Picture of Jump Arm Lift
Built by Thibault Art, this lift is a hybrid of an arm lift and a catapult-type lift. It uses the movement of the arm to bring back the catapult part, and when the arm goes back up the catapult is released. The instructions are here, and the video is below.

Step 77: Lifts Without Pictures

This step covers the lifts that don't have pictures. It's just a list of each lift, with a link to the video along with who built/invented it. Some of the videos will be videos of whole ball machines, so I've made the link start at the time that the lift appears.

Step 78: The End

Picture of The End
Well, that's the end of the guide. If you looked through all of the steps, then congrats! That must have taken a while. Again, I'll be updating this guide whenever people build new lifts.

Comment if you have any feedback or suggestions!

Thanks for viewing!

I built this lift... I used orange track clips instead of the gray connectors on the blue rods on the helix... the balls go up much smoother.. awesome design.

Shadowman39 (author)  MisterBukweet4 months ago

That sounds like a nice addition, thanks for building!

correction ... oops.. I meant white rods... getting color blind in my old age.

The 2 lifts from Revolution :)



Shadowman39 (author)  sandroknexmaster8 months ago

Added! (They're located in already-existing steps)

Yay, thanks!

I was too late O_O

New lift:


Shadowman39 (author)  dickheijboer8 months ago


For some reason, whenever I try to make a lift other than a chain lift, it DOESN'T WORK. And I am getting VERY bored of chain lifts.

Shadowman39 (author)  TheUnfortunateHobbit8 months ago

Have you tried helix lifts or arm lifts? There are many choices, so at least one of them will have to work for you. I agree that chain lifts get boring, haha.

would it be possible to set the connected arm lift at a 45 degree angle?

Reaching 45 degrees would be difficult due to the formation of the ball holders in relation to the arms. Looking back on the multiple arm lift (step 30, my design) I think it is geometrically impossible to achieve 45 degrees or higher while keeping all arms the same size and shape, and keeping the parallel-like pattern.

You could ditch the parallel-like pattern and try something like the Right-Handed Arm lift (step 31), as it has consistently designed arms, then you could modify it to 45 degrees, but this complicates the gear system.

Yeah, you're right, I've been trying for days now and not much progress. It's impossible to get the arms to tilt enough to tip the ball onto the next one.

I had the same problem when trying to make a staircase of Small Rotating Arm Lifts (Step 17). I should probably try a smaller angle...

There was ACTUALLY instructions posted for the stepper lift before Retrograde:

Shadowman39 (author)  hunter9991 year ago

I think those instructions are incomplete.

I know this is a late reply, but I actually did use that link for the main structure (though never could find it after!) The problem was that it mentioned nothing about entrance and exit paths or the crank mechanism at the top. Those all had to be improvised...thanks again to knexpert#10829476 for making better instructions of the Stepper lift from my Retrograde pictures. :-)

Too bad bezempje deleted his account and ibles :-( This look like a cool lift/shooter.I'm gonna try to build this from the pics, if I succeed I will post an ible on it...
Shadowman39 (author)  hunter9991 year ago
I'm sure people will be glad to see an Ible of this. :-)
YAY!!!!! I rebuilt it perfectly!! :-D One Q - What height do you think this should reach? At the moment I seem to get 1 metre + in height.... but I have like 4 rubber bands on the end and the motor does not have enough torque so I am yet still tinkering around. I have also modified some parts of the shooter.

I can post if you would like, let me know and i'll begin a Ible if so. :-)
Shadowman39 (author)  hunter9991 year ago
That height sounds good. What type of balls does it use? You may want to ask Sandro before posting, as he has a similar version, I'm not sure if he was posting instructions of his. If this comment has any grammar errors then sorry, I'm having a hard time reading right now (blind spot)...
Sandro said his mechanism is completely different to bezempjes so I can post. Also it uses the newer K'nex balls: these ones. I'm gonna change it round though. It seems at the moment the 2 motors shown above do not have enough torque that is required, to make it worth building as it seems to be getting very very low heights. So instead im going to try a 12V motor and tinker one in. That ought to do it! :D (*late comment)
I'm sure bezempjes also works with the old style knex balls.
And as you can see, my version works almost entirely different, so please don't hesitate to make instructions when you're finshed! :D
Does it really reach more than 1 metre height? That's quite a lot, much more than I expected ;) That's probably the biggest difference between yours and mine: the height. Mine is more designed to attach in a white floor so it can shoot the balls from a lower floor to a higher floor (or something like that)
Shadowman39 (author)  sandroknexmaster1 year ago
I remember bezempje saying that his works with older balls but they don't reach a good enough height.
Yeah older style balls are heavier.
Shadowman39 (author)  sandroknexmaster1 year ago
Eyup, which is why I like them better. Only problem with them is the holes.
Ha, sometimes when I was building the white floors of my ball machines, the balls didn't roll because they landed on the hole >.<
Shadowman39 (author)  sandroknexmaster1 year ago
Yeah, they also get stuck on rods. I mean, the odds must be rare, but it happens often. o.o

Far too often.

And it sucks if, because of a rod sticked into the whole, and you notice it to late, some gearing gets destroyed in a lift >.<

Shadowman39 (author)  Sorunome1 year ago

Yeah, that's bad. :-P

ever thought about using that phenomina for making a lift, though? :P

Shadowman39 (author)  Sorunome1 year ago

No, it would have to line up every time, lol.

This would work on a ball machine with no turns... such as the Quark.

1 metre = manually, I am yet configuring round what to do as the motor keeps clicking since it is under a lot of torque. 4 rubber bands = 1 metre+ in height so I am trying to get a 12V motor since the torque is really high


Since this lift is made to fit a yellow rod scale and the 12V motor is for a blue rod scale, I am having a hard time tinkering one in :-/. The floor would have to be quite high for this lift (like the one in your ball machine: Euphoria it is a red rod raised off the ground).

IF I am successful, it will be in my next ball machine :-)
Yeah, back then people used yellow rod boxes, now most ball machines have red rod boxes.
But I'm sure you'll find a way to attach the 12v motor :D
Can't wait for your ball machine!
Shadowman39 (author)  hunter9991 year ago
Nice! And a late comment is better than no comment. :-)
