Notes about the Lego Crane

This is probably one of the best technic lego set I ever saw. Probably because the backhoe loader is another great set. While the backhoe loader is all pneumatic (10 pneumatics!!) the crane is pneumatic (2 pneumatics), electric (includes a motor), manual (for roation, for instance) and mechanical.

Talking about the lego crane, it is awesome. First, it is enourmous. Then, it includes a lot of bricks (I tend to call them pieces, as few are the usual lego brick). Also, it tooks a lot of time to build. In my case, I took more than 8 hours of full work.

It is very interesting the way the motor works to make two different actions accordingly with a level. Regarding the pneumatic, it is used to raise the crane arm. While it raises smoothless, to lower it... you must take it with your harm, not to let it drop too quickly.

I'll prepare some photos to let you see this set more closely.
