摘要： An upright, particularly for a counterbalanced, high lift truck, comprising first and second telescoping dual mast sections disposed in fore and aft relationship, each section having laterally spaced outer, intermediate, and inner rails, and a load carriage elevatable on the inner rails of the front mast section providing a five-stage, sextuple upright. The carriage has side thrust and vertical guide roller pairs travelling in anti-friction engagement on the inner rails spaced to distribute the forces for reducing roller wear and rail distortion. The carriage has a free lift that leaves the top of the carriage flush with the top of the upright reducing the possibility of ceiling damage. The carriage also does not extend laterally beyond the sides of the mast section to reduce interfering with objects alongside the lift, such as storage racks, when engaging a load. The rails and carriage overlap to a high degree thereby allowing loads to be lifted by a truck having a smaller capacity.
