How an Electric Overhead Crane Receives Power

Cable festoons, conductor bars, or cable reels are used to transfer power from the building supply to the crane runway and bridge crane control panel. The same components are then used to supply power across the bridge to the hoist trolley.

An operator controls the movement of the crane and hoist via push button pendants or radio remote controls. All of these components combined allow the bridge and hoist to move into position over the load. Once the load is lifted, the push button pendant or radio remote control are used to drive the bridge crane to its destination and lower the load.
