Description

Technical Field

[0002] Climbing frame is also called lifting frame. It can be divided into hydraulic type, electric type, manual type and other main types according to its power source. It is a new type of scaffolding system developed in recent years, mainly used in high-rise shear wall buildings. It can climb up or down along the building. This system has completely changed the scaffolding technology: first, there is no need to turn over the frame; second, the disassembly and assembly process of the scaffolding is eliminated (it is used until the construction is completed after one assembly), and it is not limited by the height of the building, which greatly saves manpower and materials. And from the perspective of safety, it is also a big improvement on the traditional scaffolding. It has great development advantages in high-rise buildings.

[0003] The climbing frame is prone to falling accidents when climbing and descending, so the design of the anti-fall device is particularly important.
