The working principle of the hydraulic system is as
follows:
As shown in Fig.4a, when the start button is pressed, the
motor 2 is started, driving the oil pump 1 , sucking the
hydraulic oil from the oil tank into the oil cylinder 9, forcing
the piston rod move. At this time, the safety valve 5 is
closed.( the Max working pressure is already adjusted
before ex-factory. The safety valve can ensure the capacity
of the rated load, but when the pressure in the system
exceeds the limit, automatically overflow will be happened
inside safety valve to protect the hydraulic system).
Release the start button to stop the oil supply and the lifting
will stop. For lowering, first start Motor 2 to raise vehicle a
little, pull the steel ropes on two carriages to release the
safety lock mechanism, then press the lowering handle, the
valve 6 is actuated, the hydraulic oil flows back and the lift
starts lowering.
