[0002] Grandstands generally refer to seats provided for spectators to watch during large-scale collective activities such as cultural and sports events, entertainment performances, etc., and mainly refer to the audience seats surrounding the performance or competition venues. Prefabrication refers to all or most of the components (such as houses) that are prefabricated in advance. With the rapid development of the economy, the demand for venues with stands such as large gymnasiums and cinemas is increasing. Prefabricated stands will gradually be used in the construction process of venues with stands because they have good molding, save materials, reduce on-site wet operations, and protect the environment.

[0003] During the construction of prefabricated stands, tower cranes, truck cranes, crawler cranes and other equipment are mainly used for lifting construction.
