Jack Pressure for Single and Multi Pull Stressing

Intelligent Stressing System is widely applied for stressing the Pre-Stressing components in bridges and buildings.

Some of the Features are :

1. The system can control one jack for single-strand jacking and stressing.

2. The system also can control 2 or 4 sets of jacks for stressing, which make multi-items simultaneous and balanced stress.

3. Control the tension force and measure the Pre-stress elongation & force precisely. Make the additional tension and collect the Pre-stress elongation automatically, correct the elongation & forces deviation.

4. Wireless control, remote monitoring, easy operation and high maintainability.

5. Intelligent data analysis and processing, all kinds of required sheets can be generated automatically.

1. Design load per Strand in Kg

2. Losses due to Jack Efficiency (%) ( Add as per Jack Calibration Report )

3. Losses due to Anchorages (%) ( Add as per System Supplier’s Report )

4. Load per Strand including losses in Kg — P

5. Jack Ram Area in cm2 — JA
