  • Patent number: 5217343
    Abstract: A lifting mechanism for a fork lift truck wherein a side shifting carriage is slidably supported on horizontal bearing bars that are directly attached to the upright of the lift truck. Lifting bars secure the bearing bars together and carry load roller bearings supported in the guide slots of the uprights. A hydraulic motor anchored to the bearing bar assembly at one end and the carriage at the other controls horizontal sliding of the carriage relative to the bearing bars. The interfitting arrangement of the bearing bars in the carriage reduces the load moment arm, reduces the weight requirement, and provides the operator with greater visibility as compared to prior side shift carriage mounts.

  • Patent number: 4619579
    Abstract: A load-handling attachment for a forklift truck has an upright base including a downwardly open upper hook for engaging the upper crossbar of the truck's load carriage and an upwardly open lower hook for engaging the lower crossbar of such carriage. The lower hook forms part of a hook-and-support assembly. The assembly includes a base from support foot which supports the attachment in an upright free standing condition when the attachment is dismounted from the truck. The lower hook and foot move together between operative and inoperative positions when activated so that when the foot is moved to its supporting position, the lower hook disengages the load carriage to enable the truck to disengage the attachment.
