Electric separate jack Cautions

1, after 105Mpa (1050Kgf / cm2) when the high-pressure tubing factory test. However, due to the aging of the hose easily, materials lifting equipment so users need to be inspected regularly, usually six months, frequent users for three months. By checking 87.5Mpa (875Kgf / cm2) pressure test, if blasting, bumps, leakage and other phenomena can not be used.

2. When a load, avoid the quick connector removed, in order to avoid accidents and damage to the parts.

3, the machine is oil as the medium,crane manufacturer this equipment must be prepared to oil and maintenance work, in order to avoid blockage or leakage affect the results.

4, such as occurs when using an empty playing phenomenon, can be relaxing on the oil discharge screw pump, the pump vertically up and down the empty head hit a few times, and then tighten the drain screw, you can continue to use.

5, the new set of hydraulic jacks, or a long, because more memory is an air cylinder, the start of the use, the piston rod may occur slight sudden jump phenomenon, the hydraulic jack can be unloaded reciprocation 2-3 times to exclude air cavity. Long-term idle jack, do not work because of the seal and cause long-term hardening of the seal, thus affecting the service life of hydraulic jack,PA Mini Electric Hoist hydraulic jack when not in use so the monthly hydraulic jack load reciprocating motion to 2-3 times .
