Products Description
Hydraulic jack for professional tensioning steel hinge lines of prestressed reinforcement for Hydraulic Stressing Jack, tensioning operation in all kinds of steel strand anchorage. It generally need to be matched with the tension of high pressure oil pump, tension and power back to the top by the tension of oil pump.
All hydraulic fluid conduits are interior designed. Allows for more efficient and safer operation during tensioning, retraction, power lock circuits.

Advantages of the hydraulic jack for post tensioning
1. YCW (B) series jacks have 60, 100, 150, 200, 250, 300, 350, 400, 500, 650 (×10KN) and other specifications, and the standard jack stroke is 200mm.
2.Main parts of the jack is made of high strength steel, has the advantages of compact structure, light weight, small size and characteristics.
3.Short axial length, steel wire tension for short length, can save steel material.
4.Lifting and flexible, durable, easy operation and convenient maintenance.
5. Select steel to ensure material stability.
6. Fine processing to ensure quality and precision.
7. Use explosion-proof nozzle for safety protection.
8. Factory customization: can be customized.
What to note when use the bridge prestressed post tension jack:
1. If there is a runaway phenomenon during use, you can first loosen the oil drain screw on the pump body, lift the pump body vertically and run it downwards, and then tighten the drain screw to continue using.
2. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
3. This machine uses oil as the medium, so the oil and the maintenance of the machine must be done well to avoid blockage or oil leakage, which will affect the use effect.
4. For new or long-term hydraulic jacks for post tensioning, because there is more air in the cylinder, the piston rod may suddenly jump slightly when you start to use it. The hydraulic jack can be reciprocated 2-3 times without load to eliminate the cavity. The air inside. For jacks that have been idle for a long time, the hardening of the seals due to the long-term non-working of the seals will affect the service life of the hydraulic jacks. Therefore, when the Bridge Prestressed Post Tension Jack are not in use, the hydraulic jacks should be reciprocated 2-3 times a month without load.
