Abstract
The present invention discloses an overhead rail and trolley apparatus and method. The apparatus provides an overhead rail having one or more tracks. A wheeled trolley having a wheel or wheels travels upon the tracks. A stop unit on the rail is positioned to selectively halt the trolley. There is a cutout section on the rail and an insert that is attached to the rail at the cutout. The trolley wheels engage the upper surface of the insert when the trolley is halted by the stop unit. A plating on the insert increases the hardness of the insert upper surface. The insert helps prevent and/or at least lessens wear of apparatus when the trolley is halted by the stop unit.
