本厂设计的电杆钢筋预张器(见图),经实践证明,能满足工艺要求,不占用张拉台座,提高效率15~18%,节电0.1~0.15度/根。操作过程如下: 将活动卡穿过穿筋盘内孔,
The pole rebar pretensioner (see figure) designed by our factory has proved that it can meet the technical requirements and does not occupy the tensile pedestal, increasing the efficiency by 15 to 18% and saving 0.1 to 0.15 degrees per root. The operation is as follows: Pass the activity card through the hole in the ribs.
