Abstract
Official abstract text for this publication.
A regenerative hydraulic circuit for a clamping attachment limits the clamping force applied to a clamped load.
First claim
Opening claim text (preview).
I claim: 1. A load handling clamp for a vehicle, said clamp comprising: (a) a frame arranged for engagement with said vehicle; (b) a clamp arm movably attached to said frame; (c) an actuator arranged to move said clamp arm relative to said frame when fluid under pressure flows into a first actuator volume; and (d) a modulator valve arranged to enable fluid to flow from a second actuator volume to said first actuator volume when fluid in said first actuator volume and fluid i…
