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.

A method of reinforcing an overhead rail and trolley assembly comprising the steps of:
- a) providing on a rail of the assembly one or more bearing surfaces and a trolley of the assembly having one or more wheels that travel upon the one or more bearing surfaces;
- b) forming a cutout section on the rail that extends above the one or more bearing surfaces;
- c) heat treating an insert to increase hardness of the insert to a first hardness value;
- d) after step “c”, coating the insert with a coating that increases hardness of the insert to a second hardness value that is greater than the first hardness value;
- and
- e) attaching the insert to the rail at the cutout section, wherein the insert has an upper surface that is engaged by the one or more wheels.
