Self locking hydraulic jack for sale is a hot-selling product from the manufacturer of Gaodetec hydraulic jack. It is a powerful self locking hydraulic jack with a unique structure. It used for supporting heavy in the long term, it could support heavy without oil pressure, safe and reliable. Self locking hydraulic jack also could be used underwater, single acting, return with loading, the nut can be locking automatically, making loading safer, especially in the large project, it is more easily to be operated and controlled, it has pressurizer, the pres-relief valve prevents to overload in the cylinder to protect jack.
The connection of the self locking hydraulic jack adopts high pressure and thread couple, it has the function of quick use, and it also could conquer the disadvantage of an oil leak.

Self locking hydraulic jack adopts high pressure and threaded connection, which has the function of rapid use and can also overcome the disadvantages of oil leakage. Self locking hydraulic jack for sale is mainly used for the installation and disassembly of various equipment in the power, chemical, steel, construction, machinery manufacturing, mining, railway bridge, shipbuilding and other industries.

Self locking hydraulic jack also needs to pay attention to the following operations:
1) If the oil capacity is not enough in the self locking hydraulic jack, it should pour working oil (10 #) and then start to work.
2) Estimate tonnage, prohibit to overload.
3) Confirming the center of gravity of self locking hydraulic jack, finding the point of strength, meanwhile, it should consider the degree of hardness and softness of ground, whether it needs to add a plank to prevent self locking hydraulic jack will be slant when lifting.
4) After self locking hydraulic jack lifts the heavy, it should use some tough wood to support the heavy, prohibit to use self locking hydraulic jack as upholder to prevent unbalanced load, there has the danger of slant.
5) when working, firstly, it should connect quick coupling with a hydraulic jack, choose a suit placement, screw the bolt of the oil pump, and then it could start to work, unscrew the bolt, the cylinder will be unloading.

1) Self locking hydraulic jack is a single acting hydraulic jack.
2) Self locking hydraulic jack 的 nut could be locking automatically, making the 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 the piston rod is with a ringlike sphere spacer, it allows about 8% of bias factor, keeping the pressure of the jack balanced, making jack more longevity.
6) Self locking hydraulic jack for sale around the world, it can be customized into double acting hydraulic jack according to the requirement of the customer, but closed height needs to be increased.
