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 supported 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. 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 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.
Abstract: A gripping arm for a clamping attachment for a forklift has a load engaging inner arm including portions defining a load face. The inner arm is pivotal about a first axis parallel to the load face and pivots about a second axis normal to the first axis to engage and secure a load.
Abstract: 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.

Abstract: A tissue roll handling clamp, mountable on a vehicle such as a lift truck, has elongate, substantially equal-length, thin clamp arms with opposed tissue-engagement clamping surfaces. The clamp arms are capable of movement in unison by a frame assembly to alternative positions where the clamp arms extend longitudinally from the frame assembly selectively in either substantially horizontal or substantially vertical directions of extension. The frame assembly is capable of maintaining the respective clamping surfaces at substantially equal elevations to each other during such movement to substantially equalize the distribution of the weight of a clamped tissue roll between the opposed tissue-engagement clamping surfaces.
Abstract: Improvements are disclosed for a load-clamping system with variable clamping force control by which a wide variety of dissimilar loads of different types, geometric configurations and/or other parameters can be accurately clamped at respective variable optimal clamping force settings. An operator terminal cooperates with a controller to translate one or more possible load parameters into a form easily discernible visually by a clamp operator and preferably easily comparable by the clamp operator, from his visual observation, to each particular load which he is about to engage, so that the clamp operator can interactively guide the controller in its selection of an optimal clamping force setting for each particular load.
Abstract: A control system is provided for a load-handling clamp mountable on a vehicle, the clamp having a pair of opposed load-engagement clamping surfaces capable of clamping opposite sides of different types and configurations of loads. At least one of the clamping surfaces is closeable toward the other clamping surface along a direction which extends substantially laterally across a direction of forward approach of the clamp toward the load. The control system is capable of generating a variable signal indicating a desired forward, vertical and/or lateral pre-engagement position of the clamp from which the clamping surfaces can correctly engage the load.
Abstract: A modular face plate for mounting swing frame roll clamp to a rotator reduces the cost of the face plate and simplifies hydraulic connections to the clamping rams.

Abstract: 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.
