Features

Product Features
1. Mono strand jack is mainly used for single-hole tensioning. It can also be used for porous preloading, tensioning, and troubleshooting, and can be applied to high-strength steel wire bundles and steel strands of various sizes.
2. Installation and construction are very convenient: no need to rotate the arbitrarily installed working anchor; no need to rotate the radial direction of the jac; it is easier and faster to install the tool anchor plate and tool clamp piece than the original post-card type.
3. The limit plate, tool anchor and tension jack are separated and independent.
4. Better stability: the conventional post-card tensioning jack for a 3-point piston guide, this series of tensioning jacks for a 4-point piston guide; overcome the 3-point guide eccentric tensioning force often produces the phenomenon of pulling the cylinder scrap jack.
5. It overcomes the shortcomings of cumbersome and inconvenient installation of the overall front card tensioning jack at home and abroad.
