The mono prestressing jack is a multi-purpose prestressed tensioning equipment, which is easy to operate. Mainly used for single hole tensioning. It can also be used for porous pre-tightening, tension and barrier removal, and can be applied to high-strength steel wire bundles and steel strands of various specifications and sizes.  
Jack is one of the indispensable tools in tensioning and anchoring construction of prestressed engineering. No jack is omnipotent. The structure, structure size and tension tonnage of jack limit its application range. The mono prestressing jack is suitable for single hole tensioning, group anchor tensioning, troubleshooting, anchor withdrawal and supplementary tensioning. As far as the strength of prestressed reinforcement is concerned, φ 15.24 steel strand and φ 12.7 steel strand below grade 2000 can be tensioned. If all parts are replaced or removed, fine-rolled threaded rebar can be tensioned.
 
The mono prestressing jack for sale is small in size, light in weight and high in efficiency. The important thing is that the reserved length of kilocalorie steel strand is short (about 260mm). Especially suitable for working at high altitude or in places with small space position. Our company is a mono prestressing jack manufacturers, mono prestressing jack can be used with 63Mpa double-circuit oil pump.  
Structural characteristics of mono prestressing jack of our company:
1. The tension cylinder and return cylinder adopt double seals, which improves the sealing reliability. Keys are used between the small cylinder and the second cylinder, between the small cylinder and the rear end cover, and between the small cylinder and the tool ring to prevent rotation. Both are sealed by Gray ring or Sterling ring, and the sealing is reliable.
2. The second cylinder and the piston head are designed as a whole, which avoids the possibility of failure caused by welding or screw connection between the two bodies. It increases the difficulty of processing technology, but improves the reliability.
3. The improved design of wear-resistant ring and wear-resistant sleeve avoids the possibility of assembly-type stress coming out and improves the reliability of products.
4. All important stress parts are made of high-quality alloy structure or tool steel to improve hardness and strength.
   
Matters needing attention:
1. it is strictly prohibited to disassemble the jack under pressure
2. When the mono prestressing jack supplier is tested or loaded, the staff should stand on both sides, and it is forbidden to stand in the end face direction. Protective devices should be set up in dangerous areas
3. In any work, safety is the first priority, especially when the jack is used under high pressure and large tonnage, more attention should be paid to safety.
4. All people who enter the jack use site should do "when the oil pump rings, clear both ends of the jack". On the one hand, it can avoid hurting people by stretching sliding wire, and on the other hand, it can avoid hurting people by misoperation of jack parts flying out.
5. "When the oil pump is opened, the pump personnel shall not leave". Pay attention to the oil meter value at any time. On the return trip, if the oil gauge rises rapidly, stop the pump immediately.
