Description of double acting jack
The double acting jack (double acting jack) produced by our company, especially in large projects, is easy to operate and control and hydraulic jack, designed with safety pressure retaining device, built-in pressure relief valve to prevent overload, in order to protect the jack for safe operation. The connection of the device is made of high pressure rubber hose and threaded joint. The utility model has the advantages of quick use and overcoming the shortcoming of oil leakage of fast traditional joints.

Method of use

1. If the oil volume of the pump body is insufficient, it is necessary to add working oil to the pump before it can work
2. Estimate lifting weight, avoid overload use by all means
3. Determine the center of gravity of the lifting weight, choose the lifting point of the jack, at the same time must consider whether the soft and hard degree of the ground pad with tough wood, so as to avoid the risk of dumping when lifting
4. After jacking up the weight, the weight shall be firmly supported by tough wood in time. Jacks shall not be used as supports to avoid the risk of dumping due to unbalanced load
5. When in use, firstly connect the quick joint of the manual pump with the top, then select the position and tighten the drain screw on the oil pump to work. Unscrew the drain screw and unload the cylinder
