The principle of lift

The hydraulic oil is formed by the vane pump to a certain pressure. After the oil filter, the flameproof electromagnetic directional valve, the throttle valve, the hydraulic check valve and the balance valve enter the lower end of the hydraulic cylinder, the piston of the hydraulic cylinder moves upward and lifts the weight. The upper cylinder of the hydraulic cylinder returns to the fuel tank via the explosion-proof electromagnetic directional valve. The rated pressure is adjusted through the relief valve, and the pressure gauge is used to observe the reading of the pressure gauge.

The piston of the cylinder moves downwards (both weights drop). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve. The return oil at the lower end of the hydraulic cylinder is returned to the tank by the balance valve, the hydraulic-controlled check valve, the throttle valve, and the explosion-proof electromagnetic reversing valve. In order to make the weight drop smoothly, the brake is safe and reliable. A balancing valve is set on the return oil road to balance the circuit and maintain the pressure so that the falling speed will not change due to heavy objects. The flow is adjusted by the throttle valve to control the lifting speed.

The cylinder lifter is used to make the brake safe and reliable, prevent accidents, and increase the hydraulic control check valve, that is, the hydraulic lock, so as to ensure the safety self-locking when the hydraulic pipeline accidentally bursts. An overloaded voice-activated alarm was installed to distinguish between overload or equipment failure. The electronic control system can control the rotation of the motor through the explosion-proof button, and switch the direction of the explosion-proof electromagnetic reversing valve to keep the load from increasing or decreasing, and adjust the time delay through the “LOGO” program to avoid the frequent starting of the motor. Lifting is not flexible, card machine phenomenon, to extend the service life.
