Prestressing jacks model variant, the update code to (A, B, C ...... represent) the main parameters of the code, the tensile force / stroke electric hydraulic jacks, the unit kN / mm feature code, no code type code: rod type (L), feedthrough (C), cone-anchored (Z), after 105Mpa (1050Kgf / cm2) when the pedestal type test (T) group code (Y) high-pressure tubing factory. However, due to the aging of the hose easily, so users need to be inspected regularly, usually six separate hydraulic jacks, frequent users for three months. With check 87.5Mpa (875Kgf / cm2) pressure test, if blasting, raised hydraulic jacks offer, leakage and other phenomena can not be used. 6, jack spring return system structure, lifting finished, you can quickly removed, but not with a hose connected to pull jack. Separate hydraulic jack _ _ Shandong Dezhou aerospace hydraulic hydraulic jacks are provided by Dezhou City aerospace hydraulic machinery plant.
