Please explain the difference between using prefabricated building tower cranes and ordinary tower cranes.

The emphasis of cloth tower is different: when arranging tower cranes in traditional projects, it mainly focuses on the vertical transportation of materials by tower cranes. And we should take large area coverage as the first principle. Strive for full coverage of the project site. The starting point of using tower cranes in supporting projects is to meet the lifting capacity of PC components first. Tower crane has almost become a single building. Moreover, in order to ensure the lifting capacity, it is almost impossible to use the tower crane with full arm length, which leads to the situation that the tower crane is mainly single and often cannot cover the whole audience.

The choice of attachment points is different: the tower crane attachment in traditional projects is mainly due to the fact that the buildings are cast-in-place and the external frame measures for facade protection are complete. Therefore, the choice of attachment point is optional, and the tower crane can be attached to the wall near its layout. There are two reasons for prefabricated buildings: there are prefabricated components, which are equivalent to cast-in-place at present, but the implementation degree is not high in actual construction. Some items of the outer frame of the facade are not done, but only similar protective frames (such as tripods). Once the frame is lifted, it is impossible to provide a working platform for the construction work attached to the wall.
