Technical Field

[0001] The utility model relates to the field of lifting devices, in particular to a lifting device for repairing mechanical equipment. Background Art

[0002] Mechanical equipment maintenance is a technical activity that is carried out by maintaining and repairing mechanical equipment to reduce its deterioration rate, extend its service life, and maintain or restore the specified functions of the mechanical equipment. In the maintenance of mechanical equipment, lifting equipment is a key tool that can help technicians maintain and repair equipment safely and efficiently.

[0003] However, the most common lifting device for mechanical equipment maintenance is a lifting platform controlled by an electric pulley. This type of lifting platform can accurately adjust the height and is often used for maintenance work in factories and workshops. However, this type of lifting platform basically uses ropes to fix the mechanical equipment, which is not only difficult to operate but also has poor stability. There is a risk of falling off when lifting the mechanical equipment. In addition, this type of lifting platform is also relatively unsafe when carrying maintenance workers for lifting.

[0004] Therefore, in order to solve the problem that the mechanical equipment and maintenance personnel have poor stability in the lifting device and there are potential safety hazards when using it, a lifting device for mechanical equipment maintenance can be designed. Utility Model Content
