Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to an adjustable sling specially used for a building construction crane. Background Technique

[0002] When hoisting some piled-up components at the construction site, it is easy to loosen and fall, which poses certain safety hazards. At the same time, it is also necessary to hoist some materials that need to be leveled at the bottom, or transport personnel to high-altitude operations or construction sites that are difficult to reach.

[0003] After retrieval, it is found that the publication number is CN213707484U, and the name is an adjustable box-type sling specially used for a building construction crane. This application proposes that however, the existing hanging basket sling structure is relatively simple. During the transfer process of the crane, it is very difficult for the hanging basket to maintain relative stability, which leads to the parts in the hanging basket being easily scattered from the hanging basket, affecting its hoisting efficiency. Through the channel steel notch on the adapter frame being adapted to the crane boom, it is firmly fixed and does not shift. By using the lifting lug in combination with the steel wire rope, the overall angle of the sling can be adjusted, and the mobility is strong. However, when this application is actually used, it is very difficult to find a crane boom that matches its rotating frame. At the same time, when loading materials such as fasteners, it still requires workers to disassemble and take them, which is relatively inconvenient to use and can be further improved.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model
