Single acting large tonnage hydraulic jack
Lifting capacity: 50-800 tons
Journey: 50-300mm
Maximum working pressure: 70MPa
characteristic:
Single acting, gravity reset.
The piston rod is plated with hard chrome to prevent scratching and corrosion.
Dust seals reduce pollution and extend the service life of hydraulic jacks.
The special guide ring design provides support for the offset center pressure and effectively prevents direct friction between the piston rod and the inner wall, reducing wear and extending the service life of the hydraulic cylinder.
The painted surface has stronger corrosion resistance.
The bottom mounting hole provides reliable and convenient installation.
All models come with NPT3/8 "-18 quick couplings and dust caps.
The interchangeable hard treated groove saddle is a standard component configuration.
According to the working conditions, biased pressure heads and special purpose jacks can be developed.
Designed with a safety pressure protection device to prevent sudden overpressure, the structure provides multiple protective functions for the jack. It can withstand a partial load of up to 5% of the rated bearing capacity of the hydraulic cylinder. The high-pressure alloy cylinder is durable and easy to operate and control in large-scale projects.
1. When the oil level of the pump body is insufficient, it is necessary to add working oil to the pump before it can work.
2. Estimate the lifting capacity and avoid overloading during use.
3. Determine the center of gravity of the lifting object, select the point of force for the jack, and consider whether the ground is soft or hard and whether it is cushioned with tough wood to avoid the risk of tipping during lifting.
4. After the jack lifts the heavy object, it should be supported firmly with tough wood in a timely manner. It is forbidden to use the jack as a support or to use multiple jacks at the same time to avoid uneven load and the risk of tipping.
