Description

Technical Field

[0001] The utility model relates to the technical field of building hoisting equipment, in particular to a hoisting equipment for blasting and demolition of frame-type high-rise buildings. Background Art

[0002] In the process of building demolition and blasting, the commonly used lifting equipment mainly includes cranes, tower cranes, truck cranes, crawler cranes, etc. These equipment can help construction workers to safely and efficiently carry out the demolition and handling of large structures. For example, cranes can be used to lift heavy building materials and components, while tower cranes are suitable for the construction and demolition of high-rise buildings.

[0003] Currently, existing cranes balance the force by installing counterweights at the rear. The weight that cranes bear on buildings is fixed, but most of the time, the objects are not weighed before being lifted. Since the weight of high-rise buildings is unknown, the crane may topple over or tilt during lifting, posing a serious safety hazard to the workers. When lifting a building, due to the different weights of various parts of the building, the center of gravity is not necessarily in the center, causing the objects to tilt or fall during the lifting and moving, thereby causing harm to nearby workers.
