Jack has a shell, a large piston, small piston, wrench, fuel tank and other components. Works wrench to go up the small piston driven up oil tank is sucked into the lower part of the small piston through tubing and a one-way valve, driven by a small piston down, the lower part of the oil tank and the small piston is pressed down a one-way valve when the wrench plug the small piston is pressed into the lower part of the oil through the lower part of the large piston internal lines and one-way valve, because the lower part of the small piston leverage pressure increases the number of times five tons jacks, large piston area has dozens of small piston area Jilin 5 tons journey times 300 jack, hydraulic manual produced by the large piston is squeezed by Pascal principle know the size of the piston area than the same ratio and pressure. Before using the claw jack placement smooth, Liaoning 5 tons before lifting jack stroke 200, you should consider the hardness of the ground, to prevent the lifting process, produce heavy skew, dangerous. Liaoning 5 tons hydraulic jack stroke 200_ Texas aerospace _5 ton jack provided by the Dezhou City aerospace hydraulic machinery plant. Dezhou City aerospace hydraulic machinery plant (www.sdhtyeya.com) is a leader in Dezhou, hydraulic equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Texas aerospace hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the Texas aerospace hydraulic better future.
