Jinan tripod recommended a variety of high lift / hydraulic lifting platform

 Hydraulic lifts lifts principle works: vane pump hydraulic oil is formed by a certain pressure, the oil filter, explosion-proof solenoid valve, throttle valve, check valve, balance valve into the lower end of the hydraulic cylinder, the liquid cylinder piston moves upward, lifting heavy objects, back to the oil through the upper end of the hydraulic cylinder explosion-proof solenoid valve to the tank, which is adjusted by the rated pressure relief valve, pressure gauge readings by observing the pressure gauge. Hydraulic cylinder piston downward movement (both heavy fall). Explosion-proof hydraulic oil through solenoid valve into the upper end of the hydraulic cylinder, hydraulic cylinder through the lower back to the oil balance valve, check valve, throttle, explosion-proof solenoid valve to the tank. In order to decrease the weight stable, safe and reliable braking, set the balancing valve, balancing loop back to the oil on the road, keep up the pressure, so that the rate of decline from the weight change, the throttle valve regulates the flow, speed control movements. In order to secure the brake to prevent accidents and increase check valve, namely hydraulic lock, ensure that when an unexpected burst hydraulic lines can safely self-locking. Installed voice alarm overload, overload or equipment failure to distinguish. The electronic control system can be controlled by the rotation of the motor-proof button, explosion-proof solenoid valve so commutation to keep the load raised or lowered, and by "LOGO" program to adjust the time delay to avoid frequent starting motor caused Lifting is not flexible, the card machine phenomenon, and prolong life.
