Working Principle
The hydraulic oil in the SJ scissor lift platform is pressurized by a vane pump. It then passes through an oil filter, solenoid directional valve, throttle valve, pilot-operated check valve, and counterbalance valve before entering the bottom of the cylinder, forcing the piston upward to lift the load. During lowering, the hydraulic oil is directed by the directional valve to the top of the cylinder, while the oil from the bottom returns to the tank via the counterbalance valve, check valve, throttle valve, and directional valve. The counterbalance valve in the return line maintains pressure to ensure the lowering speed is unaffected by the load, and the throttle valve regulates the hoisting speed. A hydraulic lock valve ensures automatic self-locking in the event of an unexpected hose rupture.
