Product Features

1. Tensioning hydraulic cylinder, according to prestressed tension construction process and the design of the integrated numerical control cylinder, accepts computer commands and feeds back real-time tensioning data.

2. Integrated displacement and force sensor control unit, independent high-precision force measurement unit, to achieve the accuracy control of force and displacement.

3. 70Mpa working pressure, to achieve lightest weight of cylinder with the same tensioning force, reduce labor intensity.

4. Standard safety valve, protects the cylinder from damage of overload and ensures safe and reliable use.

5. Double acting, hydraulic return; baked enamel finish for increased corrosion resistance.

6. Aluminum alloy handles, lifting eye and mounting base, convenient for field applications and carrying.

7. 3/8 ” – 18NPT coupler and dust cap included on all models.

Field Applications

Prestressed tensioning of high-speed rail box girder
