The features of YDC Prestressed concrete hydraulic jack

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.

Notice: According to users' requirement, YDC through jack can be configured
