7- Servo flow-control valve, 8- Hose, 9- Hydraulic cylinder, 10- Level gauge, 11- Air filter 

 

 

The working principle of the hydraulic system is as 
follows: 

As shown in Fig.4b, 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 of 

5

10mm, 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.
