Abstract

A lift truck upright having a fixed upright section, a telescopic upright section, and a load carrier mounted on the latter section. An asymmetric lift cylinder assembly is located adjacent one side of the upright in a position which provides improved overall operator visibility through the upright. The lift cylinder is adapted to be operatively connected to the telescopic upright section by means of lifting chain structure which traverses across the upright and which is reeved on spaced and rotationally aligned sprockets supported from the cylinder assembly, the one chain end structure being connected substantially centrally of the load carrier and the other chain end structure being fixedly secured substantially outwardly of one side of the cylinder assembly. The cylinder assembly is positioned at or near a location which is one-half the projected distance between the chain end connections, or in a broader sense, approximately midway between the vertical central plane of the load carrier and the chain end connection outwardly of the cylinder assembly. It preferably comprises a cylinder assembly supported from the one side of the upright at an elevated position and having an effective stroke of substantially one-half the height of the collapsed upright. In addition a cantilevered cylinder is supported from the telescopic section for elevating thereon the load carrier to the full free-lift position.
