Abstract
A lift truck upright having a fixed upright section, one or more telescopic upright sections, and a load carrier mounted on an inner upright section. An asymmetric lift cylinder assembly is located adjacent one side or the upright in a position which provides improved overall operator visibility through the upright. The lift cylinder is adapted to be operatively connected at its upper end to a telescopic upright section for operating lifting chain structure which traverses laterally across the upright and which is reeved on spaced and rotationally aligned sprockets supported either from a telescopic upright section or from the lift cylinder assembly, the one chain end structure being connected in the two stage upright hereof a substantial distance outwardly of one side of the cylinder assembly to a member, such as to the adjacent outer upright rail, and the other chain end structure being connected centrally of the lifting or fork carriage. The cylinder assembly is operatively connected to the telescopic upright section 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. In any multi-section upright using this invention, the asymmetric cylinder assembly is located such that it projects at least partially into the area of interference by the adjacent side of the upright when in a retracted or collapsed position with the visibility of the operator from his normal line of sight through that side of the upright.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
