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.

A lift truck clamp arm assembly for engaging large cartons, which may contain large household appliances. Pivoting clamp pad support assemblies are adjustable to vary a radial spacing between a pivot pin and a clamp pad supported on the clamp arm assembly by attachment to the adjustable clamp pad support assembly, to provide desired pressure concentrations at selected parts of a carton to be gripped.

An exceptionally thin load-weighing fork assembly, having its weight sensors mounted on a fork base, overcomes fork-insertion limitations with respect to commonly used standard pallets without sacrificing load-handling capacity.

A roller load support, for mounting on a load carrying vehicle such as a lift truck, has an elongate frame with a forwardly tapering vertical thickness and an upper surface for insertion beneath the underside of a load. Different longitudinally spaced pluralities of transverse upper rollers are movable upwardly to protrude through the frame's upper surface to engage the underside of the load during the insertion process. During the insertion process, the upper rollers are pushed upward by corresponding different pluralities of transverse lower rollers which rotatably engage the floor or other surface beneath the frame and frictionally counter-rotate the upper rollers. The lower rollers are spaced nonuniformly relative to each other along the length of the frame, with such spacings increasing progressively in size, within each plurality of lower rollers, in a forward direction toward the front end of the frame. Conversely, each such plurality of lower rollers has sequentially corresponding nonuniform spacings which decrease progressively in size, from plurality to plurality, in the forward direction.
