Hydraulic boarding bridge is also called unloading platform. It is a special auxiliary equipment to realize the rapid loading and unloading of goods. The height adjustment function of forklift truck can directly enter the container batch processing. There is only one operation to realize the rapid loading and unloading of goods, which can make enterprises reduce labor and power, improve work efficiency and obtain greater economic benefits.


The working principle of the hydraulic boarding bridge is that the lower end of the piston-type hydraulic cylinder of the balance valve moves upward and the upper part of the hydraulic cylinder moves upward from the pressure of some vane pumps, oil filters, explosion-proof solenoid valves, throttle valves and hydraulic control valves, and the upper part of the cylinder moves upward from the explosion-proof tank to the oil return solenoid valves, the rated pressure regulating relief valves, and the pressure gauges observe the The downward movement of the piston cylinder (two drops) is achieved by using explosion-proof solenoid valve on the hydraulic cylinder block. Through the return valve of balancing valve, one-way fluid control valve and explosion-proof solenoid valve, the return flow of oil is reduced, the weight is reduced, the balance valve and boarding bridge balance circuit are set on the safe and reliable brake oil line, and the pressure is maintained, so that the speed of descent is not affected by the change of weight. The throttle valve regulates the flow control to accelerate and decline.
