It doesn't have the looks but gets the job done. I used a pulley system and a lot of gear wheels. (I didn't use to much gear wheels otherwise it would go very slow.) On a simple electric engine. Sorry but i am not going to post this, trust me making a crane like this is much more fun by your own. It took me to make it about 8 hours to get it up to 3kg.

I also made some other instructables.
I am gonna need instructions for this
can u show instructions for it <br>
Check out my knex crane on instructables here: https://www.instructables.com/id/Worlds-Strongest-Knex-Crane-Lifts-13lbs/
i can make it lift 3 kg<br>
can u please make easy instructions for it pleasssssseeeeee
would you please send me insteructions on how to make this please, because i looks cool!
you know what, this looks like the crane they used in chile to rescue 33 trapped miners <br>
&nbsp;WOOOOOOOOOOOOOOOW!!!!!!!!!
<p>Wow Never knew knex could do that! I knew Legos could do that but not Knex!!</p>
&nbsp;I can&nbsp;certainty&nbsp;understand that. Ow and if would poot 3,5kg on it. The rod connected to the engine bends. And if you wait to long ill just snap.
Good.<br /> I Have The ACTUAL Set For a knex crane :)<br /> <br />
&nbsp;Yeah there are more cranes of couse but i&nbsp;doubt&nbsp;&nbsp;that it can lift 3kg.
Nope..<br /> BUT<br /> It can lift a knex ball,<br /> it lowers the box, and picks up the ball, all by itself :)<br /> its weak, but very fancy!
can u make it so we can build it
Sorry but i already took it apart and i used a nylon string. I axially don't make those pictures so you all can figure it out your self and make it even better.
that isn't really the reason i forgot to make better pictures so
Nice job on the pulley system. Pictures of the top of the crane showing the pulleys would be nice, maybe you can add those (unless you took it apart already). What kind of string/cable/wire did you use?
