Product Description

Introduction
Self-locking hydraulic jack is mainly used in places that need to support heavy objects for a long time. It can still support heavy objects when the oil pressure is removed, and it is safe and reliable. It can be used underwater, for single-acting, for load retraction, and the nut self-locking makes the load safer. Especially in large projects, it is easy to operate and control. It is designed with a device to hold pressure and a built-in pressure relief valve to prevent overload for protection. These designs are used to protect the jack for safe operation. This jack adopts high-pressure hose and threaded joint connection, which is quick to use and overcomes the oil leakage of fast traditional joints.It is mainly used for equipment installation, lifting and dismantling operations in various industries such as electric power, construction, machinery manufacturing, mining, railway,bridges, and shipbuilding.

The parameters in the table may be changed due to improvement without notice

Notice
a) If there is a runaway phenomenon during use, you can first loosen the oil drain screw on the pump body, lift the pump body upright and run it downward, and then tighten the drain screw to continue using.
b) When there is a load, never remove the quick connector .
c) This machine uses oil as the medium, so the machine must be well maintained to avoid clogging or oil leakage.
d) For new jack or jack not used for a long time, there is more air in the cylinder. The piston rod may suddenly vibrate slightly when you start using it. The hydraulic jack can be reciprocated 2-3 times without load to eliminate air in the cavity. For jacks that have been idle for a long time, the hardening of the seals will affect the service life of the hydraulic jacks. Therefore, when the hydraulic jacks are not in use, it should be reciprocated 2-3 times a month without load.
