Product Description
The principle of the front clamp jack is based on hydraulic transmission and mechanical locking mechanism. The hydraulic oil enters the cylinder under pressure and pushes the piston forward. The clamping mechanism has locked the steel strand at the beginning, and with the movement of the piston, the steel strand is stretched and the prestress is gradually formed. During tension, the tension force can be accurately set and monitored by the automatic control system, and the pressure can be maintained after reaching the target value, so that the prestress can be stabilized. After the job is completed, the oil is returned to allow the piston to return, and the clamp unlocks the strand. This principle ensures that in all kinds of prestressed projects, such as the prestressed roof truss construction of industrial plants, the prestressed stress can be applied efficiently and accurately, and the stability and durability of the structure can be enhanced.

Product structure
Structural characteristics
A, Prestressing Mono jack tension cylinder and return cylinder are double sealed to improve the reliability of sealing. Prestressing Mono jack's small cylinder and two cylinders, small cylinder and back end cover and small cylinder and tool ring are all connected by a key to prevent rotation. Prestressing Mono jack are all sealed with Glay circle or Stirring, and the sealing is reliable.
B, Prestressing Mono jack two cylinder and piston head design as a whole form, to avoid the possibility of failure due to two body welding or two bodies to thread connection. It increases the difficulty of processing technology, but improves the reliability.
C, Prestressing Mono jack wear ring, wear sleeve improved design, to avoid the possibility of assembly stress out, improve product reliability.
D, Prestressing Mono jack all stressed important parts, have chosen high quality alloy structure or tool steel manufacturing, improve hardness, improve strength.
Applications
restressing 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.
