摘要： 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.

摘要： 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.

摘要： A hydraulic rotating and braking system for a lift truck-mountable load handling assembly has a hydraulically-driven worm screw with a hydraulic motor located adjacent one end of the screw and a friction brake located adjacent the opposite end of the screw. The system includes a friction brake having a brake controller located at least partially within the worm screw. The friction brake is releasable by the exhaust of fluid without the need for a fluid exhaust line extending to the lift truck's reservoir tank.

摘要： A gripping arm (32) for a clamping attachment (30) for a forklift (20) has a load engaging inner arm (3) including portions defining a load face (48). The inner arm is pivotal about a first axis (5) parallel to the load face and pivots about a second axis (6) normal to the first axis to engage and secure a load.

摘要： A fork positioner (28), usable alternatively either as an attachment to an existing load-lifting carriage with forks (10), or as part of the original equipment of a load-lifting carriage, has a pair of elongate hydraulic piston and cylinder assemblies (30,32) mountable in an interconnected parallel relationship between an upper transverse fork-supporting member ( 14) and a lower transverse member ( 16) of the carriage (10). Each of a pair of fork-positioning guide members (36, 38) has a fork-engagement surface movable by a respective piston and cylinder assembly (30,32) and connectable thereto so that the fork-engaging surfaces face substantially perpendicularly away from an imaginary plane (40) containing the respective longitudinal axes (30a, 32a) of the piston and cylinder assemblies (30, 32). An exemplary carriage mounting the fork positioner (28) is also disclosed.

摘要： Hydraulic valve circuits capable of variably limiting respective maximum hydraulic pressures at which an assembly of bidirectional. hydraulic power devices (308, 310) can move respective clamping members, such as forks or clamp arms, selectively in a closing movement toward each other, in an opening movement away from each other, or in a side-shifting movement in unison with each other, so as to provide damage-control capabilities for the control of the clamping members. The circuits preferably include one or more pressure-regulating valves (200, 202, 204) interconnected with the assembly of power devices, and capable of variably.limiting a maximum side-shifting pressure, at which said assembly can cause said side-shifting movement, in response to a maximum pressure selection. The circuits preferably include at least one override assembly (220), capable of overriding the maximum pressure selection to thereby lower the maximum side-shifting pressure automatically irrespective of the maximum pressure selection.
