En 
Hydraulic lifting platform mainly realizes lifting function through hydraulic oil pressure transmission. Its shearing fork mechanical structure makes lifting platform have higher stability, wide operating platform and higher load-bearing capacity, which makes high-altitude operation scope larger and suitable for multi-person simultaneous operation. It makes high-altitude operation more efficient and safe.
Working Principle of Hydraulic Lifting Platform
Hydraulic oil forms a certain pressure by vane pump. It enters the lower end of the cylinder through oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control one-way valve and balance valve, so that the piston of the cylinder moves upward, lifts heavy objects, and the upper end of the cylinder returns oil to the tank through flameproof electromagnetic reversing valve. Its rated pressure is adjusted by relief valve, and the pressure gauge is used to observe and read the value of the pressure gauge. (Recommend safety precautions for lifting platforms)
The piston of the cylinder moves downward (as the weight drops). The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the oil returns to the tank through the balance valve, the hydraulic control one-way valve, the throttle valve and the explosion-proof electromagnetic reversing valve. In order to make the weight drop smoothly and brake safely, a balance valve is set on the return road to balance the circuit and maintain the pressure so that the descending speed is not changed by the weight. The throttle valve regulates the flow rate and controls the ascending and descending speed. In order to ensure braking safety and prevent accidents, a hydraulic control one-way valve, i.e. hydraulic lock, is added, which can lock itself safely when the hydraulic pipeline bursts unexpectedly. An overload sound alarm is installed to distinguish overload from equipment failure.
purpose
Hydraulic lifting platform is widely used in automobile, container, mould manufacturing, wood processing, chemical filling and other industrial enterprises and production lines, to meet the lifting requirements of different operating heights, and can be equipped with various types of countertops (such as balls, drums, turntables, steering, tipping, telescoping), with a variety of control modes (division, linkage, explosion-proof), with stable lifting, frequency. Complex start-up, heavy load and other characteristics, effectively solve all kinds of lifting operation difficulties in industrial enterprises, so that the production operation is easy and comfortable.
