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.
Hydraulic valve circuitry adapted for automatic weight-responsive control of load-clamping members of a load-lifting system having a free lift mast.

The hydraulic valve circuitry provides, independently, weight-responsive control of the load-clamping members when lifting a load, full-time automatic weight-responsive force control of the load-clamping members without concurrent manual actuation of load-clamping or load-lifting selector valves, and equalization of sensed load weight so that the sensed load weight is substantially independent of the longitudinally-extensible position of the lifting device.

An improved hydraulic control system is proposed 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 for limiting clamp pressure applied by opposed clamp arms against a load, the clamp arms moveable towards and away from the load by first and second hydraulic cylinders when supplied with pressurized first hydraulic fluid. Each clamp ann is fitted with at least one bladder holding a second fluid. The hydraulic control circuit has a charging system for expanding at least one bladder using the first pressurized hydraulic fluid and at least one fluid line, together capable of selectively pressurizing the second hydraulic fluid in the bladder(s) of each clamp arm. The system is employed in a method for limiting clamp pressure applied by opposed clamp arms against a load. In the method, pressurized fluid is provided in the first and second cylinders until the clamp arms contact the load, and after the clamp arms contact the load, the system automatically increases bladder pressure in a manner independent of further movement of the clamp arms toward the load.

Coupler for earth moving or materials handling machine
A coupler is configured to couple an implement to an earth moving or materials handling machine. The coupler includes a locking member for locking a pin of an implement into a coupler in the recess. The locking member is driven by a hydraulic arrangement, with the hydraulic cylinder body being formed integrally with either the coupler body or the locking member. The coupler may be adapted to accommodate a range of implement pin spacings and/or diameters, so that the coupler can be used with different implements and in particular with different makes of implement.
