Torque Testing

Overview

Torque Testing is a fundamental mechanical verification process utilized to ensure that critical fasteners—such as bolts, nuts, and screws—have been tightened to the precise rotational force specified by the Original Equipment Manufacturer (OEM). In the assembly and maintenance of cranes, hoists, and Elevated Work Platforms (EWPs), achieving the correct torque is essential for preventing the loosening of components under intense vibration and dynamic loading. Incorrect torque application is a leading cause of mechanical failure; under-torqued fasteners allow joint movement leading to rapid wear and fatigue, while over-torqued fasteners can exceed the yield strength of the steel, causing immediate stripping or sudden rupture. Our Torque Testing services provide independent, calibrated verification of fastening forces across all critical mechanical assemblies, ensuring that maintenance overhauls and new equipment commissioning meet exact engineering tolerances.

Ensuring correct torque application is a core component of responsible plant maintenance and WHS compliance. Our technicians deploy a range of highly accurate, NATA-calibrated electronic and click-type torque wrenches to systematically audit fastener connections on slew rings, winch mounts, hydraulic cylinder anchors, and counterweight assemblies. For principal contractors and maintenance managers, comprehensive Torque Testing provides the necessary quality assurance documentation to validate that servicing has been executed correctly. By identifying and rectifying torque discrepancies before they evolve into catastrophic mechanical failures, our services enhance the reliability of your lifting fleet, extend asset lifespan, and ensure the ongoing safety of personnel operating in demanding high-risk environments.
