ABSTRACT:
Cylinder head (81) of a hydraulic lift cylinder (39) includes a fluid input port (74) and first fluid output port (75) to be connected respectively to a pump (46) and to a power steering mechanism (40). These ports preferably open at one and the other side surfaces of the head. The head further includes a second fluid output port (83) and fluid inlet port (84) which open at a front surface of the head. These ports are connected through an inside of a cover member (49a, 50a; 201; 250a) detachably mounted on the front surface of head. The head includes therein a flow divider (47) which divides inflow of the input port into first and second flows directed respectively to the first and second output ports. Fluid returned into the inlet port is directed towards a first control valve assembly (48) for the lift cylinder. A second control valve assembly (49; 250) for an auxiliary implement can be provided using the cover member as its valve housing with remaining fluid pipings to the input and first output ports unchanged. A third control valve assembly (50) can further be provided by mounting it on an upper surface on the second assembly.
