施工现场钢筋冷拉工艺比较繁琐 ,而由加工厂加工 ,又受钢筋长度和距离的限制 ,不便于运输。现场冷拉需做地锚或冷拉台座 ,且要搬运卷扬机 ,穿绕滑轮组以及回程系统。一次性投资较大 ,且工艺复杂 ,施工进度较慢。为此采用YPD60S型大行程水平千斤顶 ,较好地解决了钢筋现场冷拉的动力源和“双控”问题 Cold-drawn steel construction site more complicated process, which by the processing plant, but also by the length and distance restrictions, not easy to transport. On-site cold-drawn to be done to anchor or cold bench, and to move the hoist, around the pulley block and return system. One-time investment is large, and the process is complex, the construction progress is slow. For this reason, YPD60S large-stroke horizontal jack is adopted, which solves the power source and “double-control” problem of cold drawing on the steel bar
