It sucks oil from the oil pump and pushes the piston in the oil cylinder to lift the platform. When descending; pressure oil flows back to the oil tank through the solenoid valve under the control of the speed limit valve and flow adjustment. When the oil cylinder is overloaded, the pressure oil output by the oil pump directly flows back to the oil tank through the overflow valve (safety valve), In order to prevent the rupture of the oil pipe and the elevator falling out of control,every inlet pipe of oil tank has one-way speed-limiting valve. Even if the oil pipe is ruptured, the elevator can be guaranteed to descend at a normal speed.
