Product details

1.Product Description：

It is a multi-purpose prestressed tensioning equipment with easy operation. Mainly used for single hole tensioning. It can also be used for multi-hole pretension, tension and obstacle removal, and can be applied to high-strength steel wire bundles and steel strands of various specifications and sizes.

2.Structural features：
A. The tensioning cylinder and the return cylinder are double-sealed, which improves the sealing reliability. Key connections are used between the small cylinder and the second cylinder, the small cylinder and the rear end cover, and the small cylinder and the tool ring to prevent rotation. Both are sealed with Gray ring or Sterling ring, and the seal is reliable.
B. The second cylinder and the piston head are designed as an integral form, which avoids the possibility of failure due to welding of the two bodies or connection of the two bodies with threads. Increased processing technology difficulty, but improved reliability.
C. The improved design of wear-resistant ring and wear-resistant sleeve avoids the possibility of the assembled type coming out under force and improves product reliability.
D. All important stress-bearing parts are made of high-quality alloy structure or tool steel to improve hardness and strength.

3.Multi Mono Strand Jacks ：
can be used for single-hole tensioning and group anchor tensioning one by one. The mono jack is light in weight, easy to operate, high in efficiency, and has a short reserved length of steel strand, which is especially suitable for high-altitude or small-space operations.
