Monorail Trolley

An item used for transporting material from one location to another by means of an overhead track, beam, cable, or similar method. The trolley consists of either a single wheel or set of wheels, the wheel frame, and a device for transporting the material to be relocated. The transporting device may be an arm which is directly attached to the material or a basket, sling, or the like. For trollies which utilize hoists in the overhead transportation of material, see trolley, hoist.
