[0002] In modern industrial production and construction, hoisting operation is an important link and is widely used in material handling, equipment installation, building construction and other fields. Although the traditional hoisting equipment meets the basic hoisting needs to some extent, it still has many deficiencies in operation flexibility, space utilization and operation efficiency. Especially in complex and changeable working environment, such as precise hoisting operation in narrow space, the traditional equipment often appears to be inadequate.

[0003] In order to solve the above problems, a series of improved hoisting devices appear in the market, among which the cantilever hoisting device is gradually favored because of its compact structure and flexible operation. However, the existing cantilever hoisting device still has some limitations in design. For example, the cantilever part of some cantilever hoisting devices usually adopts fixed connection mode, which cannot adjust the angle according to actual needs, limiting the operation range; at the same time, the winding and unwinding of the lifting rope usually rely on manual operation, which not only is low in efficiency, but also has safety hazards. In addition, some devices lack enough stability and reliability in structure, which are difficult to bear large load or long time continuous operation.

[0004] Therefore, it is necessary to design a cantilever hoisting device to solve the above problems. CONTENT OF THE UTILITY MODEL
