  • Patent number: 10550886
    Abstract: A slide-bearing assembly capable of enabling sliding of a load-carrying surface relative to a load-supporting structure, such that the slide-bearing assembly may include a first arrangement of at least one substantially nonmetallic elongate bearing element capable of extending along a first load-carrying surface and a second arrangement of at least two substantially nonmetallic elongate bearing elements capable of extending longitudinally in series along a second load-carrying surface parallel to the first load-carrying surface such that the second load-carrying surface is in non-coextensive supportive relationship with the first load-carrying surface.
    Type: Grant

  • Patent number: 8403618
    Abstract: A fork positioner, usable alternatively either as an attachment to an existing load-lifting carriage with forks, or as part of the original equipment of a load-lifting carriage, has a pair of elongate hydraulic piston and cylinder assemblies mountable in an interconnected parallel relationship between an upper transverse fork-supporting member and a lower transverse member of the carriage. Each of a pair of fork-positioning guide members has a fork-engagement surface movable by a respective piston and cylinder assembly and connectable thereto so that the fork-engaging surfaces face substantially perpendicularly away from an imaginary plane containing the respective longitudinal axes of the piston and cylinder assemblies. An exemplary carriage mounting the fork positioner is also disclosed, together with a wireless hydraulic function control system for use with the fork positioner or other multi-function load handlers.

  • Patent number: 6390763
    Abstract: A lift truck sideshifting carriage has an upper transverse slide guide with an upwardly-protruding first lip for slidably supporting an upper transversely-extending slide of a sideshifting frame. The sideshifting frame has a second upwardly-protruding lip for supporting the load-handling implement of the lift truck. The slide guide has a transversely-extending reinforcing portion which protrudes forwardly from beneath a forwardly-facing surface of the first lip, and extends throughout at least a major portion of the transverse length of the slide guide. A sideshifting motor, for moving the sideshifting frame transversely with respect to the slide, is mounted to the slide guide externally beneath the reinforcing portion of the slide guide. The forwardly-protruding reinforcing portion of the slide guide and the upwardly-protruding first lip of the slide guide are formed monolithically and homogeneously as a single member.
