1. YM prestressing anchorage system is designed and certified for a wide variety of applications:
• use of 13 mm (0.5") and 15 mm (0.6") strands of all grades (1,770 or 1,860 MPa) including galvanised strands or greased sheathed strands
• prestressing units holding up to 55 strands
YM Series products are composed of tensioning anchor head, tool wedges, bearing anchor plate and spiral reinforcement.
2. HOW STRESSING WORKS:
The unique feature of our post-tension system is its special wedge locking procedure. The wedges always remain in contact with the strands during the stressing operation. As the pressure in the jack is released, the wedges automatically seat into the conical holes of the anchor head.
