China Ydc Feed-Through Multi-StrHydraulic Stressing Jack

Product Description
Stressing jack is a specialized machine for prestressing engineering. It can be applied both to pre-tension and post-tension project. Using different models, you can simultaneously stretch a bunch of 2 to 22 strands. The nominal tensile force is 65t up to 1000t.
Our YDC series stressing jack is a product by our independent research and development. After tens of years' improvement, it is compact in size, smooth and steady while working, and very reliable in leak tightness and service life.
The stressing jack is powered by our ZB series high-pressure electric oil pump.

Model Selection
1. Considering the loss of tensile force by resistance, the stressing jack outputs about 95% of the nominal tensile force. If the jack needs strict and continuous working, we recommend a higher nominal tensile force than the load, by about 20%.
2. The diameter of the center hole shall be 17mm larger than the outer circle of taper holes.
3. In order for your convenience, we made a table of model selection for stretching 1860Mpa Ø15.24mm strands at 0.85Fptk tensile force.
