[0002] The roof system of large venues usually uses a long-span steel structure as the structural force system, and a canopy is set on it to realize the building function. At present, the vertical transportation of the canopy panels usually adopts the following two methods:

[0003] The first is to use a tower crane for hoisting. This method uses a tower crane throughout the entire process from hoisting of components to installation completion, which has low construction efficiency and affects the development of other hoisting work, and has low economic efficiency;
