Self-locking jack

Details of the self-locking jack :

I. Use
Self-locking jack , self-locking jack : Self-locking jack is mainly used for places that need to support heavy objects for a long time. It can still support heavy objects when removing oil pressure, and it is safe and reliable. Can be used underwater, single-acting, load retraction, nut self-locking to make the load safer, especially in large projects, it is easy to operate and control and hydraulic jack . It is designed with a safety pressure holding device and a built-in pressure relief valve to prevent overload to protect it. Jacks facilitate safe operation. The connection of this device uses high-pressure hoses and threaded joints. It is fast to use and overcomes the shortcomings of the traditional traditional oil leakage. It is mainly used for equipment installation in various industries such as electricity, construction, machinery manufacturing, mining, railway bridges, and shipbuilding. Lifting disassembly work.

Second, use method 1, if the pump body is not enough oil, you need to add working oil (10 # engine oil) to the pump to work.
2. Estimate the lifting weight and avoid overloading.
3. Determine the center of gravity of the lifting object and select the point of force for the jack. At the same time, you must consider whether the softness and hardness of the ground is lined with tough wood to avoid the risk of falling when lifting.
4. After the jack lifts the heavy object, the heavy object should be supported with tough wood in time. It is forbidden to use the jack as a support, so as to avoid unbalanced load and the risk of falling.
5. When in use, first connect the quick connector of the manual pump to the top, then select the position, and tighten the oil drain screw on the oil pump to work. Loosen the drain screw and unload the oil cylinder.
6. For electric pump, please refer to the electric manual

The parameters in the table are subject to change without notice.

Fourth, matters needing attention

a) If runaway occurs during use, first loosen the oil drain screw on the pump body, lift the pump body upright and hit it downwards a few times, then tighten the oil drain screw to continue using.
b) When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
c) The machine uses oil as the medium, and the maintenance of the oil and the machine must be done to prevent blockage or oil leakage, which will affect the use effect.
d) For new or long-time hydraulic jacks, because there is more air in the cylinder, the piston rod may have a slight jump phenomenon when it is used. You can reciprocate the hydraulic jacks 2-3 times under no load to eliminate Air in the cavity. For long-term idle jacks, the seals harden due to long-term non-operation of the seals, which affects the service life of the hydraulic jacks. When the hydraulic jacks are not in use, the hydraulic jacks are reciprocated 2-3 times a month without load. .
