LEC Post Tension Mono Strand Hydraulic Jack
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 LYM15 and LYM13- 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.
2. 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.
3. Matched Oil Pump: 50Mpa, 63Mpa Electric Oil Pump
4. Application: bridges, high buildings, coal mine , railway and subway, water conservancy and hydropower engineering .
5. Features: it can tension the followings PC Strand and Stel Rebar
A It can tension standard pc strand diameter 12.7mm, 15.24mm, 15.7mm, 16mm pc strand.
B It can tension non-standard pc strands diameter 8.0mm, 9.52mmn, 10.8mm, 12.9mm. 17.8, 21.6, 21.8mm, ect.
C It also can tension 16mm, 22mm, 24mm, 26mm, 28mm, 32mm, steel rebar
6. Warranty Time: One Year, we will send you Repair Kits if you need any time.
