TT MECHANICAL TELLTALE

Mechanical Telltales are low-cost, easy-to-install mine and tunnel roof safety monitoring devices designed to give clear, at-a-glance information about roof movement within and above the reinforced height.

Ultra-visible reflective colour bands indicate the roof movement, and millimeter scales allow highly accurate monitoring of trends over time. The units have been developed to provide exceptional in-hole stability and water diversion to ensure reliable and precise information is being displayed.

Also available as a triple-height version where long tendons are installed on drivage in addition to rockbolts, and as a cable-bolting version with longer anchor wires and an alternative colour scheme.
