CPC classification number: B66F9/183

Abstract: A load-bearing assembly including a clamping-force sensor in a pivoting support assembly that is adjustable to vary a radial spacing between a pivot pin and a clamp pad mounted on the support assembly. A plurality of clamping-force sensors may be included in a plurality of pivoting clamp pad support assemblies to support a clamp pad and may be arranged to sense the magnitude of a clamping force exerted by a particular adjustable pivoting clamp pad support assembly and send signals indicative of the magnitude of the force to a controller. A load sensor may be located between a pivot pin and a bearing block, or strain gauges may be mounted in the pivoting bearing block so as to measure forces carried through the bearing block. Force values sensed and transmitted to the controller may be used to evaluate and adjust the clamp arm assembly to grasp a load with a desired clamping force or distribution of clamping forces.

IPC: B66F9/14

Abstract: Attachment assemblies for industrial material handling equipment are shown and disclosed. In some embodiments, the attachment assembly includes a carriage assembly having a carriage, wherein the carriage is mountable to industrial material handling equipment. The attachment assembly additionally includes a frame assembly connected to the carriage. The attachment assembly further includes a faceplate assembly fixedly attached to the frame assembly. The faceplate assembly is configured to receive one or more support members for supporting a load. The faceplate assembly includes one or more load cells configured to measure horizontal and vertical forces applied to the one or more support members.

Abstract: An improved hydraulic control system for a lift truck attachment having opposed clamp arms that selectively grip and release a load. The improved hydraulic system utilizes a secondary hydraulic force control circuit that increases the gripping force on the load independently of inward movement of the clamp arms.
