[0002] Lifting equipment is a kind of lifting and handling machinery widely used in ports, workshops, power plants, construction sites and other places. Multi-action lifting machinery that vertically lifts and horizontally carries heavy objects within a certain range belongs to material handling machinery.

There are at least the following disadvantages in the use of existing lifting equipment: 1. Existing lifting equipment cannot be moved flexibly, and personnel are required to operate the equipment all the time during the material handling process; 2. When the existing equipment is used to carry materials, there is no limit on the carrying weight, which is easy to cause equipment damage and affect the service life. Therefore, we have launched a kind of lifting equipment with high safety. Utility Model Content
