Semi-gantry crane, as a special lifting equipment, combines the characteristics of gantry crane and single-beam crane. One side of it is supported by legs on the ground track, and the other side is supported by the factory building or other structures, presenting a unique semi-gantry structure. This design makes it more flexible in space utilization, especially suitable for working environments with fixed buildings or site restrictions on one side. Structurally, the semi-gantry crane is mainly composed of main beams, legs, trolley running mechanism, car running mechanism, lifting mechanism and electrical control system. When working, the lifting mechanism lifts the heavy objects through the hook, the trolley can move horizontally along the main beam to adjust the position of the heavy objects in the horizontal direction, and the trolley running mechanism drives the crane to move longitudinally along the track to complete the handling of the heavy objects. Semi-gantry cranes are commonly found in various factory workshops, warehouses, docks and other places. In the factory, it can efficiently complete the lifting of raw materials, the transfer of semi-finished products and other tasks; in the warehouse, it can be used for loading and unloading and stacking of goods; in the dock area, for the cargo loading and unloading operations of some small ships, semi-gantry cranes can also play an important role, greatly improving the operating efficiency and reducing labor costs.
