Description

Technical Field

[0001] The utility model relates to the technical field of construction hoisting equipment, in particular to a novel hoisting platform. Background Art

[0002] After the main structure of a high-rise building is completed, the required equipment needs to be installed in the high-rise building. However, due to the limited space of the elevator, it is difficult to transport large equipment through the elevator. During the construction process, workers use the lifting platform to receive the large equipment, and the tower crane moves the lifting platform to lift the large equipment into the high-rise building. However, although the current lifting platform can limit the position of objects during use, it has poor flexibility during use. Most of them require manual adjustment to limit the position of objects. In addition, it is inconvenient to quickly lock the protective door during use, and it is inconvenient to operate. Therefore, we have launched a new type of lifting platform. Utility Model Content
