A lift truck upright having a fixed upright section, a telescopic upright section, and a load carrier mounted on the latter 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 connected to the telescopic upright section by means of a pair of lifting chains. One of the chains is reeved on a pair of spaced and rotationally aligned sprockets supported either from the lift cylinder assembly and from the fixed upright section, or from the opposite ends of a transverse bar structure which is supported from the cylinder assembly. In either embodiment the one chain traverses the upright and is fixedly secured at one end at one side of the cylinder assembly and at the other end to the remote side of the telescopic section of the upright. The second chain is adapted to be reeved on a sprocket mounted from either the upper end of the lift cylinder assembly or from said transverse bar structure, the one chain end thereof being fixedly secured on the same one side of the lift cylinder as is the first chain, and the other end being secured to the near or adjacent side of the telescopic section. A second centrally mounted cantilevered cylinder is mounted centrally of the telescopic upright section for elevating thereon the lifting carriage to a full free-lift position. |
