FAQs
Q
What does the RSM-JCP(C) test and what method does it use?
+
A
It measures effective prestress under anchors in post-tensioned bridge structures using the reverse tension method. Typical uses include checking effective prestress under single-strand anchors and detecting non-uniformity within a tendon group or at the same section. It references standards such as T/CECS G:J51-01-2020, JTG/T F50-2011, and CQJTG/T F81-2009.
Q
How does it improve on-site safety and automation?
+
A
The system provides automatic load control, intelligent multi-stage pressure management, and dual safety protection values (initial stress, design control stress, warning limits) for safe staged pressurization—even in harsh conditions. Real-time monitoring plus wireless data upload support cloud-enabled reporting and management.
Q
Is it portable, and what are the key hardware specs?
+
A
Yes. It combines a lightweight high-pressure micro pump (up to 70 MPa, full-oil weight ≤28 kg, 60 V DC lithium battery/AC power) with a 12.1″ high-brightness LCD host (wireless/wired, ≥30 m wireless range). The single-strand hydraulic unit offers 2 displacement channels, 1 pressure/1 force channel, displacement error ≤0.1% FS, load accuracy ≤0.5 grade, 0–250 kN pressure range; the special jack is front-clamp type, 270 kN nominal tension, 57 MPa nominal oil pressure, φ19 mm center hole, 100 mm max stroke.
