摘要
预应力７孔群锚张拉用千斤顶———ＹＣＮ１５０及ＹＣＮ１５０Ｚ的设计采用新型密封装置、引导器、顶压器、自动工具锚，使得千斤顶张拉锚固可靠，自重大大降低，并实现了工具锚的自动装卡和拆卸，提高施工效率一倍以上。
The multi-strand jacking system,type YCN150 and YCN150Z for Seven-Strands anchorage,are designed by means of advanced technology,such as new type sealing device,guiding device,wedge pusher and auto-clamping jaws.Through these means,the stressing reliability is ensured,the self-weights of jacking is reduced,the jaws is automatically gripped and released,and the tension efficiency is increased more than one times.
