Abstract
Official abstract text for this publication.
A load-handling clamp mountable on a lift truck has one or more hydraulic clamping cylinders of the type having two or more sequentially extensible stages capable of applying either load-weight-responsive variable hydraulic load-clamping force or, alternatively, load-size-responsive variable hydraulic load-clamping force, without risking the clamp's dropping of a clamped load. The length of the hydraulic clamping cylinder(s) may in some applications extend generally forwardly from a supporting lift truck, and in other applications extend generally laterally from a supporting lift truck.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hydraulic load-clamping and load-lifting system including at least one load-clamping hydraulic cylinder of a type having at least first and second sequentially extensible stages capable of applying a clamping force to a load in response to a source of pressurized hydraulic fluid, said first stage having a first fluid pressure-receiving area greater than a second fluid pressure-receiving area of said second stage, said first stage being capable of appl…
