I. Reasonable Matching The tires at the front and rear, left and right of the machinery must be reasonably matched. The tires assembled on the same machinery should ensure the same brand, specification, structure, tread pattern, and load. Radial tires and bias-ply tires cannot be mixed; tires with different rim diameters, widths, or different cross-sectional […]

I. Working Principle The hydraulic oil is pressurized by a vane pump and then passes through a filter, a flameproof electromagnetic reversing valve, a throttle valve, a pilot-operated check valve, and a balance valve to enter the lower end of the hydraulic cylinder. This causes the piston of the hydraulic cylinder to move upward, thereby […]
