Product Description
Prestressing jack is one of the indispensable and important tools in the tension anchorage construction of Prestressing bridge project. No Prestressing jack of any kind is a panacea. Prestressing jack structure, structure size and tension tonnage limit its range of use. Prestressing Mono jack is a kind of multi-purpose prestressed tension equipment. Prestressing Mono jack is mainly used for single-hole tensioning, and can also be used for porous prestressing, tensioning and drainage. Prestressing Mono jack is suitable for a variety of specifications and sizes of high-strength steel wire and steel strand.
Prestressing Mono jack is suitable for stressing single hole tension, group anchor by root tension, troubleshooting, withdrawing anchor, filling tension. As far as Prestressing strand wire strength is concerned, you can stretch the following 2000 grade Φ15.24 steel strand, Φ12.7 steel strand, if you replace/unload the parts, you can stretch the fine rolled screw rib (customer put an order) rebar and so on.
Prestressing Mono jack is small, light weight and high efficiency. It is important to note that the reserved length of the kilo-card strand is short (about 260mm). It is especially suitable for high altitude or small space location.
Prestressing Mono jack is used with double circuit oil pump 63Mpa and above.

Product structure
The structure of the front clamp jack
The front clamp jack is a kind of tool specially used for the tensioning and anchoring construction of prestressed projects, and its structural design has unique advantages, which is suitable for a variety of scenarios such as single-hole tensioning, group anchor tensioning, troubleshooting, unanchoring, and additional tensioning. The following are the main structural features of the front clamp jack:
Structural characteristics
Double seal design: tension cylinder and return cylinder are double seal design, improve the reliability of the seal. The small cylinder and the second cylinder, the small cylinder and the rear end cover and the small cylinder and the tool ring are connected by keys to prevent rotation. The seal is made of Glay ring or Ster ring to ensure the sealing effect.
Integral two cylinder and piston head: The two cylinder and piston head are designed as one piece, avoiding the possibility of failure due to two body welding or two body threaded connection.
Improved wear resistance design: The wear ring and wear sleeve have been improved to avoid the possibility of assembly force out and improve the reliability of the product
Applications
The rapid tensioning construction method of the front clamp jack is suitable for the tensioning construction of various Bridges, railway, highway, municipal and other traffic Bridges and prestressed structural projects in the construction industry. The new type of front clamp jack rapid tension construction method, with the help of the front clamp jack to pull the steel strand inside the beam, the characteristics are: The working process is to install the working clip on the wire harness on the beam, and after fastening and positioning it, install the limit plate with the matching diameter on the steel strand, install the extended sleeve, install the front clamp jack, install the tool clip, quickly tensioning, and return the oil loose. The new type of fast tensioning construction method of the front clamp jack integrates the advantages of various domestic front and back clamp jack construction technology, and the construction method is simple, safe, fast, efficient, environmental protection and energy saving, which greatly improves the production efficiency, saves the project cost and shortens the construction period.
