YCQ Front-Gripping Jack (Single-Hole)

The YCQ-series front-gripping jack is a type of hollow-core, prestressing jack designed for the single-strand tensioning of bonded tendons (compatible with YJM13, YJM15, YJM17.8, and YJM21.6 anchorage systems). It is widely used in projects involving pre-tensioned or post-tensioned prestressed concrete structures, bridges, and geotechnical anchoring. The jack is particularly well-suited for high-altitude operations and is highly portable.
