摘要： A hydraulic valve assembly (10) for selectably delivering hydraulic fluid from a supply of hydraulic fluid to one of a first hydraulic operator (80) and a second hydraulic operator (82) is disclosed. The assembly includes first (32) and second (34) supply ports which communicate with the supply (18) and four operator ports (44,46,48,50). First (44) and third (48) ports communicate with the first hydraulic operator (80). Second (46) and fourth (50) ports communicate with the fourth hydraulic operator (82). First (36) and second (38) chambers are provided. The first chamber communicates with the first supply port and first and second operator ports. The second chamber communicates with the second supply port and third and fourth operator ports. Two selection valves (60,61) operating in unison are each located in each chamber. The selection valves operate between a first position at a first hydraulic fluid pressure and a second position at a second hydraulic fluid pressure. In a first position, the valves permit fluid communication of the first and second supply ports with the first and third operator ports, respectively. In a second position, the valves permit fluid communication with the second and fourth operator ports.

摘要： A side shifting and fork positioning assembly for a lift truck is disclosed. The assembly includes a carriage (2) which moves in a lift truck mast. The carriage includes a pair of horizontally spaced apart vertical members (6) and a frame support member (4) secured transversely to the vertical members. A side shift frame (20) slides on the carriage. An upper cross member (22) of the side shift frame supports two forks (5) along their hook portion. Hydraulically actuated cylinders (12, 14) located in the frame support member move the side shift frame. The assembly also includes first and second fork shoes (40a, 40b) movably secured to the side shift frame. Each of the fork shoes define a contact surface to engage the forks. The contact surface of the fork shoes is located no further forward than a front face of the upper cross member. The assembly includes a fork positioner (3) which moves the first fork shoe relative to the second fork shoe, where the fork shoes are maintained at an equal distance from the center of the side shift frame.
