1.Single acting hydraulic jack.
2.Nut could be locking automatically, making load more safe.
3.Specially-made composite material coating has stronger anti-corrosion, and less force of friction.
4.Overflow hole has the function of limiting stroke.
5.The top of piston rod is with a ringlike sphere spacer, it is allow about 8% of bias factor, keeping the pressure of the jack balanced, making jack more longevity.

6.Self-locking hydraulic jack can be customized into double acting hydraulic jack according to the requirement of customer, but closed height need to be increased.
1.If the oil capacity is not enough in the pump, it should pour working oil(10#) and then start to work.
2.Estimate tonnage, prohibit to overload.
3.Confirming the center of gravity of jack, finding the point of strength, meanwhile, it should consider the degree of hardness and softness of ground, whether it need to add a plank to prevent jack will be slant when lifting.
4.After jack lift the heavy, it should use some tough wood to support the heavy, prohibit to use jack as upholder to prevent unbalanced load, there has the dangerous of slant.
5.when working, firstly, it should connect quick coupling with jack, choose a suit placement, screw the bolt of oil pump, and then it could start to work, unscrew the bolt, the cylinder will be unloading.
