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.

The most fascinating video I've ever seen.

I don't quite understand how they are doing it, but I get that they lift the parts up to near the top, assemble it somehow maybe inside the top piece, and the crane pushes itself upwards?

I love cranes!

That crane doesn't look like it could handle alot of weight looking at the weight balance at the back, also if the arm was put together on the ground that would require alot of space on the ground, it doesn't seem like a very efficient crane.

I look after the maintenance on a couple of similar cranes in Australia so I know what's involved. Everytime they are put up, there are huge amounts of inspections to be done prior. If done properly they are very safe. I loved the vid too as you normally don't see it sped up. Well done mate.

I believe it was about three hours for the stuff in this video.

Very interesting.What this vid needs is some funky music though.
