Tensionable Cable Bolt (TCB)
Superior ground control for the most challenging environments
Minova’s patented Tensionable Cable Bolt (TCB) System offers an advanced support with all the installation versatility of the traditional cable bolts while providing the ability to tension the cable during the normal roof bolting cycle. The TCB System provides compression into the roof and ensures “top-to-bottom” tension of the cable, which places the anchorage higher in the roof structure to eliminate “anchorage shock” during loading.
The TCB System can be used for primary support and as secondary support in applications where traditional cable bolts are used and enhanced beam building is needed. Common application areas include: tail gates, bleeder, recovery
room, set-up room, head gates, intersections and other mine areas where longevity and additional support is required.
