Multi Purpose Bridge Erecting Machine Hydraulic Prestressed Jacks For Tensioning

Description of Post Tension Mono Strand Stressing Jack

The front cassette 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 preloading, tensioning, and troubleshooting, and can be applied to high-strength steel wire bundles and steel strands of various sizes.

Technical Parameter of Mono Jack

Components of Mono Jack

Post-Tensioning Hydraulic Jack Structure feature

1. Both the tension cylinder and the return cylinder are double-sealed, which improves the sealing reliability. The small cylinder and the second cylinder, the small cylinder and the rear end cover, and the small cylinder and the tool ring are all connected by keys to prevent rotation. All are sealed with a Gree 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 due to the welding of the two bodies or the threaded connection of the two bodies. It increases the difficulty of the processing technology but improves the reliability.

3. The improved design of the wear-resistant ring and the wear-resistant sleeve avoids the possibility of the assembly type being forced out and improves the reliability of the product.

4. All the important parts under stress are made of high-quality alloy structures or tool steel to improve hardness and strength.

Hydraulic Prestressed Jack Safety Precautions

1. It is strictly forbidden to dismantle the jack under pressure
2. When the jack is tested or loaded, the staff should stand on both sides, and it is forbidden to stand in the direction of the end face, and protective devices should be installed in the dangerous area
In any job, safety is the first priority, especially if the jack is suitable for high pressure and large tonnage, and more attention should be paid to safety.
3. Avoid the misoperation of jack parts flying out and hurting people.
4. Always pay attention to the oil gauge value. When returning, if the pressure of the oil gauge rises rapidly, stop the pump immediately.
