he working principle of the hydraulic system is as
follows:
When the UP button is pressed, the motor is started, driving
the oil pump, 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, and Max working the 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 UP button to stop the oil supply and the lifting will
stop. For lowering, press and hold the UNLOCK button, the
electromagnetic safety lock mechanism will be released,
meanwhile press the DOWN button, the solenoid valve 6 is
actuated, the hydraulic oil flows back from the hydraulic
cylinder into the oil tank through the solenoid valve 6 and flow-
control valve 7, and the lift starts the lowering.
