Ever wonder how cranes that build high-rise buildings get built? They can build themselves upwards!

they make cranes so that they can be set up in sometimes near impossible spots. the tower crane is assembled to a predetermind hight with the use of a crane. the only time you use the climber is when you can't reach the crane with another crane. Also towers aren't meant to be heavy lifters, and that's a lebherr and it's top of the line stuff.

The "climber" is a specially designed mast section that acts as a spacer/jacking mechanisim; it holds onto the new mast section and allows it to be rolled into position. It has a 21 foot hydraulic cylinder on each corner that jacks the crane up, workers pull the 20 ft. mast section into alignment and pin it. Note that the crane has to be perfectly balanced while jacking. Thats why the next section is raised & held precisly to ensure the delicate hyd. cyls. are not bent during raising.
