Air scissor lift characteristics and working principle

A lift device lifts the running gear, hydraulic mechanism, electric control mechanism, supporting institutions. A certain pressure of hydraulic hand truck oil from the vane pump, the filter, explosion-proof solenoid valve, throttle valve, check valve, balance valve into the lower end of the hydraulic cylinder, the upward movement of the piston cylinder, improve weight matter, the upper end of the hydraulic hand truck cylinder return oil through flameproof solenoid valve back to the tank, which is adjusted by the rated pressure relief valve, pressure gauge watching the pressure gauge readings.
