QYC Series Steel Strand Front-end Hydraulic Floor Prestressed Tensioning Jack

Specification of QYC Series Steel Strand Front-end Hydraulic Floor Prestressed Tensioning Jack

Descriptions:

1. QYC front-end fixed jacks have internal re-usable anchor which can automatically clamp and loosen the wedge.

2. They are mainly used for GYM15 and GYM13- type various single tensioning with bonded and unbonded prestressed cable.

3. Notice: QYC type front-end fixed jacks could be matched with different size, length of the top cover, retreat anchor device, to be used in the experiment by root tension pre-tightening, tension retreat anchor and stay cable tone with single cable.

4. We can manufacture all kinds of anchor and equipment according to your requirement and drawings.

Applications:

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

QYC Series Front-End Hydraulic Floor Prestressed Tensioning Jack is applied in hole tension, group of anchors tension one by one, which can be used for troubleshooting, for back- up anchor and tension, especially used for high altitude or in a small space.

Features:

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 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.

Notice: according to users' requirement, prestressed concrete jack for anchors and pc strand can be configured
