SG STRAIN GAUGE ROCKBOLTS

Rugged and robust strain gauge rockbolts are an invaluable tool for measurement and recording of the distribution of bolt loads in mines and tunnel support environments.

Distributed in an array across the excavation as part of the bolt pattern, they provide precise information that can be used to maximize safety and also to significantly reduce costs through optimizing the placement of roof support collateral

The SG rockbolts can be supplied with multiple pairs of strain gauges so that axial loads and bending movements can be measure along its full length and comes with our free Exbolt for Windows software package to enable data download and storage
