Intelligent tensioning hydraulic system is mainly used in bridge intelligent tensioning project. Hydraulic system equipped with displacement sensor and force sensors form a closed-loop control system. The intelligent tensioning can be realized by operating control device to carry out accurate and effective tensioning construction. It can store and process the data, has strong anti-interference ability, and can guarantee the prestressed tensioning construction quality effectively.
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
