Product Description
Hydraulic Mono Single Strand Post Tensioning Jack
1. QYC series of mono strand hydraulic jack have internal re-usable anchor which can automatically clamp and loosen the wedge.
2. They are mainly used for LYM15 and LYM13- type various single tensioning with bonded and unbonded.
3. Notice: QYC type hydraulic jack could be matched with different size, length of the top cover, retreat anchor device, to used in the experiment by root tension pre-tightening, tension retreat anchor and stay cable tone with single cable.
The features of QYC type mono strand hydraulic jack
The prestressed concrete hydraulic jack for achors and pc strand are the new designed products in our company, are the upgrades of the primary jacks.
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 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, prestressed concrete jack for achors and pc strand can be configured
