The lift is a kind of lift equipment composed of a walking mechanism, a hydraulic mechanism, an electric control mechanism and a supporting mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve and balance valve, so as to make the piston of the hydraulic cylinder move upward and lift the heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof 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.
A lift shall be defined as a lifting mechanical device or device of a platform or semi enclosed platform on which people or goods are lifted and lowered in a vertical up and down passage.
The development of lift is in a peak state. In order to improve the utilization rate of the site, most manufacturers or individuals choose multi-storey buildings, which also requires a device to facilitate the lifting and lowering of goods. Ordinary elevator has high cost and low bearing capacity, so it is not suitable for loading dozens of tons or hundreds of tons of goods, so a high bearing capacity hydraulic elevator has been developed to assist production and cargo transportation. The hydraulic elevator is not only safe, but also has a large load capacity, and it is easy to maintain, which makes the development of this special industry faster.
