The hoisting trolley is a key component in equipment such as bridge-type cranes and cable-type cranes that enables the suspended load to achieve three-dimensional spatial displacement. Its core functions include running along the bridge frame or load-bearing cables, achieving the lifting of the lifting gear, and some types also have the function of rotation. Hoisting trolleys are widely used in scenarios such as suspended monorail systems and boom-type cranes. They are mainly composed of traveling mechanisms, lifting mechanisms, etc., and are responsible for the horizontal and vertical movement of the load. In bridge cranes with returnable functions, the rotation of the lifting gear can be additionally achieved
