& nbsp; The goods lifting platform is a type of lifting equipment composed of walking organization, hydraulic organization, electric control organization, and supporting organization. Hydraulic oil is composed of a vane pump to generate a certain pressure. It enters the lower end of the hydraulic cylinder through an oil filter, a explosion-proof electromagnetic directional valve, a throttle valve, a hydraulic control check valve, and a balance valve, causing the piston of the hydraulic cylinder to move upward and lift the heavy object. The return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and the additional pressure is adjusted through an overflow valve. The pressure gauge is used to investigate the reading value of the pressure gauge.
