A hoist and trolley mechanism allows industrial bridge cranes to easily lift and lower heavy tools and supplies.
The hoist and trolley, along with the bridge and the runway, make up the three main components of industrial bridge cranes.
The hoist and trolley is a hook-and-line system that runs along the length of the bridge crane. It is used for hoisting up objects and then dropping them at appointed destinations.
With the aid of an industrial bridge crane, loads can be easily transported back and forth between opposite sides of an industrial facility. The bridge crane moves along the length of the facility while the hoist and trolley moves along the width of the facility.
