ABSTRACT:
A load force bypassing apparatus is provided for a work engaging support assembly, such as a lift truck fork and mast assembly, having a plurality of rollers movably mounting a carriage assembly on a generally upright support with the rollers normally subjected to load forces imparted against the carriage assembly during a normal load crowding operation. The bypassing apparatus is positioned between the carriage assembly and the upright support in direct force transmitting relation to effectively isolate the rollers from the load forces during the normal load crowding operation.
