[0002] Curtain wall is the outer wall of a building. It is non-load-bearing and is hung up like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is composed of a structural frame and inlaid panels. It is a building enclosure structure that does not bear the load and function of the main structure.

[0003] A crane is required during the installation and hoisting process of the curtain wall. Currently, the existing cranes used for curtain wall installation mainly have a counterweight block at the rear end of the crane to increase the lifting capacity of the crane. The lifting capacity of the crane is limited by the number of counterweight blocks, and the crane is not fixed stably. When lifting heavy objects, the crane poses a safety hazard.
