Abstract
A trolley assembly is provided including a pair of trolley brackets with an axle extending outwardly from each of the trolley brackets. Bushings adapted to rotatably engage each of the axles are provided with a wheel fixedly attached to each of the bushings. The bushings include an interlock to prevent rotation of the bushing with respect to the wheel. A pendant is attached to the pair of trolley brackets. The components of the trolley assembly can be replaced on a one-to-one basis with parts of prior art trolley assemblies.
