Preloading and Torque Loading

Swantest provides specialist expertise in preloading a variety of steelwork installations. Using calibrated hydraulic equipment, we apply controlled loads to steel support systems—an effective and reliable method for minimising movement in adjacent areas during excavation and for managing deflection within the structure.

This service includes the preloading of flying shore props, king posts, and raking props in large-scale basement excavations. Additionally, we can preload holding-down bolts or anchors used to restrain substantial forces, such as those on tower crane bases or retaining structures.

We also offer precise torque loading to ensure the correct and uniform clamping of connected surfaces. This prevents overstressing, distortion, or failure of bolts, studs, and other fasteners. Swantest delivers this service across a range of structures, offering independent quality assurance to support our clients’ project requirements.
