Description

TECHNICAL FIELD

[0001] The utility model relates to hoisting technical field, concretely to a novel retractable hoisting device. BACKGROUND

[0002] In modern industrial production, construction and logistics transportation and many other fields, hoisting operation is a very critical and frequent operation process. The traditional hoisting device gradually exposes many limitations that are difficult to overcome in practical application, and it is difficult to meet the increasingly complex and changing work requirements.

[0003] The traditional hoisting device lacks the ability to adapt to different hoisting environments and cargo hoisting requirements. When facing some work scenes with complex space structure and variable operation angle, the support angle of the traditional hoisting device often cannot be flexibly adjusted, or even if it can be adjusted, the adjustment process is relatively complicated and time-consuming, which affects the work efficiency.

[0004] In addition, the early hoisting equipment often has poor mobility. For example, some large fixed hoisting machines are fixedly installed in a specific place and cannot be flexibly moved to other work sites. This results in the need to set up corresponding hoisting equipment at each location when facing hoisting tasks at multiple different locations, which not only causes a substantial increase in equipment purchase cost, but also greatly wastes resources. Even some hoisting devices with mobile functions are prone to instability phenomena such as shaking and sliding due to uneven stress or external environmental factors, and may even cause component damage, construction accidents and other adverse consequences.

[0005] Therefore, we propose a novel retractable hoisting device to solve the problems mentioned above. CONTENT OF THE UTILITY MODEL
