How the hydraulic platform works

How the hydraulic platform works

The hydraulic lifting platform mainly realizes the function of lifting through the pressure transmission of hydraulic oil. Its shear fork mechanical structure enables the lifting platform to have higher stability, and the large working platform and higher load-bearing capacity enable high-altitude operations. The scope is larger and suitable for multiple people to work at the same time. It makes high-altitude operations more efficient and safer. The working principle of hydraulic lifting platform The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the cylinder moves upwards and lifts the weight. The oil return from the upper end of the hydraulic cylinder is returned to the fuel tank through the flameproof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge. (Recommended 　 Precautions for the safe use of lifting platforms) The piston of the hydraulic cylinder moves downward (that is, the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil from the lower end of the hydraulic cylinder returns to the tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects fall smoothly and brake safely and reliably, a balance valve is installed on the oil return line to balance the circuit and maintain the pressure so that the descending speed is not changed by the weight. The throttle valve adjusts the flow rate and controls the lifting speed. In order to make the brake safe and reliable, and prevent accidents, a hydraulic control check valve, namely hydraulic lock, is added to ensure that it can lock itself safely when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure. use The hydraulic lifting platform is widely used in various industrial enterprises and production lines such as automobiles, containers, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different working heights, and can be equipped with various table tops (such as balls, rollers, Turntable, steering, tilting, telescopic), with various control methods (split, linkage, explosion-proof), has the characteristics of stable and accurate lifting, frequent starting, large load capacity, etc., effectively solving the difficulties of various lifting operations in industrial enterprises, making Production operations are effortless.
