Roofminder^TM System

Use our Roofminder^TM System to monitor the change in mine roof load. Increasing load on the indicator is a warning of impending danger and a signal to pull out equipment & personnel from the area.

Roofminder^TM Can Tolerate Considerable Variation in Roof Geometry

Because of the Roofminder^TM system’s spherical geometry, plate angles up to 15 degrees with the bolt axis will not bend the bolt nor interfere with the strain indicator.
