  • Patent number: 5139385
    Abstract: The attachment (20) provides inner forks (54, 56) and outer forks (58, 60) that are directly and independently driven for handling juxtaposed pallets. The fork assembly (26) is carried by guide members (44, 48, 62, 66) that are constructed so that when two juxtaposed pallet loads are carried, there is substantially no downward deflection of the laterally outermost portions of the loads. A hydraulic control system is included for controlling the four operation functions performed by the attachment (20). The hydraulic control circuit is designed so that no electrical components need be mounted to the attachment (20).

  • Patent number: 4890973
    Abstract: A push-pull slip sheet handling attachment for a forklift truck is fork-supported. The attachment is connected to the fork upright portions. In one embodiment, the base frame of the attachment includes side frame members that straddle the fork uprights and fork connectors that are vertically movable on a base frame support foot between latching positions behind the fork uprights and release positions below the fork uprights. In another embodiment, the base frame is mounted in front of the fork uprights and has pin-type fork connectors adjustable vertically and movable transversely behind the fork uprights between latching and release positions. Both embodiments have lightweight, compliant base frames comprising an open framework having thin side frame members and a minimum of cross frame members.
