6.2 Oil pump
Oil pump is gear pump
6.3 Multiway valve
The multiway valve is two piece four body in pattern,the high pressure oil from working pump
is distributed,by multiway valve rod,to lifting cylinder or tilting cylinder.The safety valve,which can
control the pressure of the system,is set on the upper side of multiway oil-in mouse.The
self-locking valve, main function is to prevent the terrible result caused by mishandling the
controlling rod when there is no pressure source for tilting cylinder,is set on tilting valve piece.@
there are one way valves fitted between inlet and oil suction inlet of lifting valve slice and between
inlet of lifting valve slice and inlet of tilting valve slice.
