Product Description

                      Large Tonnage Prestressing Hydraulic Post Tension Jack

Descriptions:
1. It is suitable for the tension of group anchors with 1860-2000 sizes, Φ15.24, Φ12.7 strands.
2. In some certain circumstance it can be used in the working of pushing, jacking and transforming and so on.
3. Easy to operate and used widely.
Notice: according to users' requirement, YDC prestressing jack can be configured

Features:
YDC Feed-through jacks are the new designed products in our company, are the upgrades of the primary jacks.
1. Using new seals, to synchronous strengthen the seal-ability under great pressure.
2. Using special alloy steel with heat treatment process, reducing the cylinder's expansion ratio in the tensioning
process. So the life of seals and sealing performance can be improved about 20%.
3. In the tensioning the operating process, jacks is easily damaged under overpressure because of the jack-based
pullback cylinder, so we added the overpressure valve on the jacks to pressure production. Meanwhile we improved
the original of commonly used structure by wire disc and flanged disc, to make the bearing capacity for oil pressure
strengthen. So enormously reduce the possibility of mechanical damage due to improper operation. 

In the word, the YDC series feed-through jacks' performance is improved, and widely used in pre-stressing and post
stressing construction.
