Tower crane installation

The cross arm of tower crane is transported to the construction site in sections first, and then assembled on the ground. After assembly, hoist the cross arm with a heavy crane, and then connect it with the main tower (i.e. the vertical tower with cab). The main tower itself has self-lifting function. When the tower crane needs to be lifted, the jack-up frame of the main tower will lift the main tower, so that a space about 3 meters high appears in the middle of the tower body. Then use the cross arm of the tower crane to put a new section of the tower body into this space, and then tighten the bolts. The process of disassembly is just the opposite.
