The QYC250-200 front clip-through hydraulic jack is a multi-purpose pre-stressed tensioning device, which is easy to operate.
Mainly used for single-hole tensioning. It can also be used for multi-hole pre-tensioning, tensioning and obstacle removal, and
can be applied to high-strength steel wire bundles and steel strands of various specifications and sizes. It is suitable for
single-hole tensioning, group-anchor tensioning one by one, troubleshooting, anchor withdrawal, and supplementary tensioning. As
far as the strength of the pre-stressed tendons is concerned, Φ15.24 steel strands and Φ12.7 steel strands below class 2000 can be
tensioned. If the parts are replaced/removed, the finish-rolled screw ribs can be tensioned (customers place an order) Rebar etc.
The jack is small in size, light in weight and high in efficiency. The important thing is that the reserved length of the thousand
card steel strand is short (about 260mm). Especially suitable for high-altitude or small space operations. The jack is used in
conjunction with a dual-circuit oil pump greater than or equal to 63Mpa.

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.
