3）Lift System
The lifting system consists of an oil cylinder and a power unit and allows the fork to rise
and fall.
●When it is in the lifting state, start the motor and extract the hydraulic oil with the oil pump.
The hydraulic oil is input into the lifting cylinder through the check valve and hydraulic tube,
and therefore lifting the object. Meanwhile. The solenoid valve is power off and the
hydraulic will be blocked.
●When it is in the lowering state, the motor is closed and the solenoid valve is power on
(the hydraulic oil can pass). The hydraulic oil passes the lifting cylinder, hydraulic tube,
solenoid valve and the oil return tank of the governor valve.
●The governor valve is used to limit the maximum speed of descent
4）Safe oil passage
The overloaded machine and blocked oil tube will make the pressure of the system over
13.5Mp, wherein the overflow valve will be open to ensure the safety of the system.
