Bridge cranes consist of several main parts that work together to lift and move heavy loads. The main components of a bridge crane include the bridge, end trucks, hoist, and trolley. The bridge spans the width of the workspace and supports thehoist, and trolley. The end trucks, located at either end of the bridge, support the bridge and allow it to move along the runway system. The hoist, which is attached to the trolley, is responsible for lifting and lowering the load. The trolley moves along the bridge and positions the hoist above the load. Other important components of a bridge crane include the controls, which can be either wired or wireless, and the electrical system, which powers the crane. Proper maintenance and inspection of all these parts are essential for safe and efficient operation of a bridge crane. Regular maintenance can extend the lifespan of the crane and prevent costly repairs.
