Description

Technical Field

[0002] The cantilever construction platform is an overhead construction equipment, also known as a cantilever construction platform or cantilever operating platform. It is mainly composed of platform structure, cantilever beam and support system, which can be hung on the outer wall or cantilever structure of the building to provide a safe and stable working platform for construction workers. Indoor cantilever platform is a common building structure, and its design and construction require precise height control to ensure the safety and stability of the structure. However, when the construction height cannot be determined, a series of problems may arise.
