Knex Crane Capeble of Lifting 3kg

Introduction: Knex Crane Capeble of Lifting 3kg

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 can certainty 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.

    Nope..
    BUT
    It can lift a knex ball,
    it lowers the box, and picks up the ball, all by itself :)
    its weak, but very fancy!

    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?
