This video shows my knex crane. The first half of the video is pictures of my design, then it has a 3 second clip from the botttom of the carriage, then it goes into the video of it actually lifting the 13 pounds.
If I get a lot of people asking for instructions, i will post some instructions.

can u make instructions for it <br>
I have dismanteled it along time ago, rebuilt it, and re-dismantelled it. <br>The second time that i made it, I looked at about 5 pictures of it, and it actually turned out better. <br>I think that you could make it just by watching the video.
just completed a 17lb lifter.
haha <br>nice timing <br> <br>I had a challenge for another member that ended a day before you posted that comment.
wish i still had my K'nex i would beat this lmao<br>
im changling this myself
good luck<br>Im working on a stronger design as of yesterday<br>RustyMia<br><br>
another thing is your gears are slipping<br>
I was worked about them slipping so I doubled them back to back. I am workin on making it stronger and I have only one gear per mesh so I made a little harness device to keep the gears straight. <br>Rustymia<br>
ok im up to 7 1/2 lbs and im not even finshed...
I hanged how the weight is attached changed the gear ratio and gave it Mir supports and it lifted 16 but now I have no idea how to measure more because I have no more weights that will fit on it<br>Good luck<br>RustyMia
hm well mines at 15 lbs with some sagging on my rails now to build up the sides so it can support the weight.
your welcome
13 lbs isn't much for a k'nex crane, there are ways to make a motor more efficient when paired up with gears and stuff. The structure is lacking in places, it could use more North/South support etc. Otherwise, nice try.
It is very stable when it is alone and when it has a load on it. It is a lot of weight when you realize the it is lifting over 2 times its own weight. Let me se a crane that can lift more
Challenge accepted.
U have 369 days begin<br>
I'm sure that this is not the strongest one in the entire world lol. Lifting capacities can be immense with the right design and pulley layout. It's still good, though.
I no but it's the stongest I could find!<br>
Not bad at all.
