Advanced Bridge Load Testing Units for Infrastructure Safety
Mobile and scalable bridge testing solutions delivering precise load analysis, compliance assurance, and structural confidence
Smart Testing Technologies for Bridge Safety and Compliance
Bridge load testing units are critical tools for evaluating the ability of bridges and overpasses to safely carry design and live loads. By applying controlled loads and monitoring real-time responses, these systems help engineers validate structural strength, detect anomalies, and inform maintenance strategies. This webpage delves into the technology, design, and benefits of modern bridge load testing rigs, demonstrating how they empower safer and more cost-effective infrastructure.

Case Studies
Bridge Assessment – Georgia DOT (U.S.)
STRUCTURAL TESTING TOOLS deployed a hydraulic load frame with GAO Tek strain gauges to conduct AASHTO-compliant load rating on a highway overpass. Wireless data capture enabled remote engineer review and rapid certification.
Seismic Retrofit Validation – California Highway
A damaged bridge required proof load testing following seismic repairs. Our modular bridge load unit applied cyclic loads while GAO RFID telemetry logged deflection and stress, confirming improved resilience.
Rail Overpass Survey – Ontario, Canada
A Canadian rail authority contracted us to certify an aging steel overpass. Utilizing hydraulic jacks and digital displacement sensors from GAO Tek, the system verified structural compliance under CSA S6 guidelines.
