2. The effective construction covering area of the crane is large, which can give full play to the overweight ability of the tower crane and improve the working efficiency of the tower crane.
3. Small input cost for the whole machine.
Ii. Disadvantages of the internal climbing tower crane
1. As the tower crane is directly supported on the building, it is necessary to check the structure. If necessary, it should be temporarily strengthened to increase the cost.
2. The internal climbing tower crane is installed in the elevator shaft. Due to the requirements of the installation structure, a certain number of holes must be set on the shear wall of the elevator shaft, which brings certain adverse effects to the main structure.
3. Since the tower crane is installed in the elevator shaft of the building, the installation of the tower crane will affect the construction schedule of the basement structure.
4. It is difficult for the driver to communicate with the ground, and the driver's vision is not wide enough, which brings some hidden dangers to the safety of hoisting.
5. After the completion of the project, the dismantling machine downstairs needs auxiliary lifting equipment, which is difficult to dismantle and unsafe.
