YDC post-tension Hollow jack are advanced devices based on their former structures of YDC, redesigned with high-strength steel, advanced structures, sealing function, optimization technology. This new type features tight structure, lightened weight, short axial length, stands saving by the short reserved length in prestressing strand anchorage. The results of the test show its perfect performance, durability, flexibility of lifting, the convenience of using and preparing. It can be used in pre-tensioning and post-tensioning. With different attachments, respectively tensioning XYLM, QYM clip group anchor, DM, LZM anchorage, etc.
