Description

technical field

[0001] The invention relates to tool equipment, in particular to a lifting device. Background technique

[0002] Lifting equipment is a device that enables people or things to move back and forth between low and high places. The important indicators of lifting equipment are: 1. Safety; 2. Detachability; 3. Has the function of crisis relief and escape.

[0003] At present, the common lifting mechanisms include civil elevators and building elevators. Civilian elevators have high requirements for supporting facilities, and generally cannot be used for outdoor operations; cables are used for lifting, and cable breakage is prone to fall accidents. In addition, power failure during operation is not conducive to escape. Construction lifts are suitable for outdoor use, but steel pipe supports are required, making the construction relatively complex and costly. At the same time, construction lifts are lifted by cables, which are prone to fall accidents if the cables ...
