Product Description

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 the design superiority of double acting hydraulic jack, increasing 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 has central to the piston, it is widely used for nuclear power plants, tunnel engineering, foundation, and other similar projects. And it can be connected with prestressed craft, it is also used for the post-tension prestressed bridge project.



2. Features:
Double acting design can highly improve convenience.
Built-in safe valve can protect the jack when overloading.
Cylinder can bear Max loading when Max strokes.
High quality seal ring makes the jack's life longer, with no oil leakage.
