2.2 Main functional features

1) Enhanced host framework, fully protected structure.

2) The integrated structure design of oil source and control cabinet occupies less space.

3) The design of spoke type load sensors provides higher force accuracy and feedback sensitivity.

4) Servo pump direct closed-loop control has higher closed-loop accuracy and faster response compared to digital valve systems.

5) Adopting an integrated industrial tablet computer (randomly equipped with a printer), real-time display of curve and process data, and automatic calculation of shrinkage. Humanized design of software interface, rich information, and direct printing of reports.

6) Standard pre tensioning oil source and jack, the oil source is controlled by an electric contact pressure gauge to ensure consistent tension of the pre tensioned steel strand, avoiding the disadvantage of inaccurate pre tensioning tension during manual operation.

7) Randomly equipped with a mobile jack (anchor support device) for users to install anchor ring pads, avoiding the disadvantage of using forklifts during on-site testing.
