Double acting hollow hydraulic cylinder manufacturers
1.Product Description:
Double acting hollow hydraulic jack is connected with all the design features of single acting hydraulic jack and design superiority of double acting hydraulic jack, increase its operation and working speed, especially, it can make the best of its hydraulic force in the long stroke engineering.
This type of hydraulic jack have central in the piston, it is widely used for nuclear power plant, tunnel engineering, foundation and other the similar projects. And it can be connected with prestressed craft, it is also used for post tension prestressed bridge project.
2. Features:
Double acting design can highly improve the convenience.
Built-in safe valve can protect jack when over loading.
Cylinder can bear Max loading when Max stroke.
High quality seal ring make the jack's life more long, no oil leakage.
