Button-head anchorage

The DM-type button-head anchorages include four types, i.e., A, B, C and K, which can be used to stretch Φ5 and Φ7 high-strength steel wire tendons with standard strengths of 1,570MPa, 1,670MPa and 1,770MPa. They are mainly used in post-tensioned prestressed concrete members. It is equipped with LD series heading machine for forming steel wire head, and ZB4-500 high-pressure oil pump, YDC600 (YCQ60Q) jack (matching tension rod) and YDCL-type pull rod jack for tensioning.
