technical field

The utility model relates to the technical field of high-rise building hoisting, in particular to a hoisting device used for external transportation of super high-rise buildings.

Background technique

In order to improve the utilization rate of urban land and save the use of urban land resources, urban buildings are gradually developing towards high-rise and super high-rise buildings. For this kind of buildings, there are many materials and equipment to be transported during the construction process, and a lot of construction waste is generated. In addition, most high-rise and super high-rise buildings have equipment floors, and the electromechanical equipment installed in them is heavy and large in number, which brings huge challenges to transportation.

The traditional method is to rely on the construction general contractor to build a public transportation channel inside the building, or build hoisting equipment such as tower cranes outside; but the former is limited by the structural design and construction cost of the building itself, and the general contractor usually does not consider large-scale The transportation needs of equipment, and the latter also has the defect of site limitation, so the above method can only be used to solve the transportation problem of ordinary building materials, and is not suitable for the transportation of large electromechanical equipment on the equipment layer.
