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 jack can be configured

Applications:

It is matched with prestressed anchorage widely used in the  construction of bridge and buildings, railway and subway,  water conservancy and hydropower engineering .

Features:

YDC Feed-through jacks are the new designed products in our company, are the upgrades of the primary jacks.

1. Using the 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 that 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 clinder, 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 that 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 poststressing construction.

Information we need to know as followings so we can recommend you suitable equipment and give you best price.

1. How many holes anchors(maximum holes numbers) do you stress or what is maximum numbers of prestressed cable you tension?”
2. What is your required maximum capacity and stroke?
3. How many sets do you need?
