double acting hydraulic jack cylinder

1.ISO9001:2008 2.Compact structure 3.Light weight 4.Small volume 5.Wide use and so on

This is our new product ( Hydraulic Jack Cylinder ) with the following feature :

1) Secure and reliable,with excellent anti-corrosion and anti-fatigue capacity. Special damping devices in the system are available to reduce the damages caused by the tendon vibration.

2) The radius of the individual strand deviation is very small,which can furthest decrease dimensions of diaphragms .Forces on every strand are individual at one deviation ,so stress concentrations and greatly lessened .

3)good flexibility.  When equipped with different accessories,it is able to tension multi-strand anchorage,heading anchorage and stay cable anchorage etc.

4)Convenient for inspection,maintaining and replacing tendons if needed.

5)series hydraulic jack cylinder is widely applied to pretensioning and post-tensioning.  It have successfully worked on numberous project,including bridges,buildding,tunnels and harbours.
