Computer control pre-stress values, to reduce error range from ± 15%(traditional technology) to ± 1%.
Sensor collects the displacement from strand steel and pre-stress values from cylinder, computer do real time data analysis and adjustment.
One computer Synchronous control two or more tension cylinders.
Standardized tension process to avoid pre-stress loss.
Automatic and standard process, computer control loading velocity, stop points and load holding time, no artificial influence and environmental effects.
Automatically generate reports. Better traceability, high efficiency.
The pre-stressed tensioning system consists of system mainframe, pump station and tension cylinders. System mainframe collects the required stress information and sends signal to pump station, to control valve, velocity of flow, oil flow, and pressure. Then drive tension cylinders move synchronously. Meanwhile Pressure measurement sensor and tension displacement sensor continually provide real-time data to system mainframe for analysis and adjustment, so as to achieve required tension and elongation.
