ABSTRACT OF THE DISCLOSURE A truck upright having a fixed upright section, three or more telescopic upright sections, and a load carriage mounted on a telescopic upright section. A sole 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 con- nected at its upper end to a first telescopic upright section for operating first lifting chain structure which traverses laterally across the upright and which is reeved on spaced and rotationally aligned sprockets supported from said telescopic section. The chain first lifting structure in all embodiments comprising either single or multiple chains has one chain end (5) fixedly secured a substantial distance outwardly of one side only of the cylinder assembly to a member, such as to the adjacent outer upright rail, and the other chain end(s) secured to the second telescopic section either centrally thereof or at opposite sides thereof. A third telescopic upright section on which is mounted the load carriage is itself mounted for elevation relative to the second telescopic section. Second lifting chain structure is also adapted to traverse laterally across a portion of the upright and is supported from the second telescopic section by sprocket means and is reeved thereon such that one chain end structure is secured to the third telescopic section and the other chain end structure is connected to the first telescopic section. A second lift cylinder is mounted centrally of the third section for elevating thereon a load carriage to a full free-lift position.
