1）Lifting State
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.
2）Lowering State
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
