Abstract
The invention is concerned with an improved carriage guide and mast stiffener for a lift mast of the sort used on a lift truck or the like. Such a lift mast comprises a pair of spaced apart outer mast members, a pair of spaced apart inner mast members between the outer mast members, each slidably mounted in a respective one of the outer mast members and a carriage structure mounted on the inner mast members for translation therein. The improved structure of the present invention comprises a pair of rails each affixed to extend longitudinally along a respective outer surface of a respective one of the outer mast members and a pair of bearings affixed to the carriage structure, each snugly but slidably engaging a respective one of the rails and allowing relative longitudinal translation of the carriage structure relative to the outer mast members while preventing other translation therebetween.
