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).
