At present, a large number of mining projects in my country require corresponding mining equipment during mining. Most of the current mining equipment is mining cranes. When using mining cranes, they lift the mined ore and put the ore into the dump truck. The current mining cranes are relatively high, and hydraulic lifting platforms are generally used during maintenance to transport staff and maintenance equipment to the required height.

[0003] When the current hydraulic lifting platform is in use, the hydraulic lifting device is used to lift the lifting platform to the required position, and then the mining crane is repaired. However, the height of the protective plates around the current lifting platform is fixed, and the heights of the maintenance workers are different, which leads to different centers of gravity of the workers. When the lifting platform rises to the required height, the workers move inside the lifting platform to repair the crane. During the maintenance process, the workers' center of gravity changes due to horizontal movement. When the taller workers are repairing, the center of gravity shifts and the lifting platform tilts, which causes the workers to separate from the lifting platform, so that the safety of the lifting platform cannot be guaranteed. For this purpose, a vehicle-mounted hydraulic lifting platform is provided. Utility Model Content
