How does a hydraulic lifting platform work?
The hydraulic lifting platform mainly achieves the lifting function through the pressure transmission of hydraulic oil. Its shear fork mechanical structure provides high stability for lifting, wide working platform, and high bearing capacity, making the high-altitude work range larger and suitable for multiple people working at the same time. It makes high-altitude operations more efficient and safer.
Working principle of hydraulic lifting platform
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the piston of the hydraulic cylinder to move upwards and lift the heavy object. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure is adjusted through the overflow valve. The reading value on the pressure gauge is observed through the pressure gauge.
The piston of the hydraulic cylinder moves downwards (i.e. the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow and controls the descent speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
Purpose
Hydraulic lifting platforms are suitable for various industrial enterprises and production lines such as automobiles, containers, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different operating heights. At the same time, they can be equipped with various table forms (such as balls, drums, turntables, steering, tilting, and telescoping), combined with various control methods (transfer, linkage, explosion-proof), and have the characteristics of smooth and accurate lifting, frequent starting, and large load capacity, Effectively solving various lifting and lowering difficulties in industrial enterprises, making production operations easy and free.
