The IN-ROOF™ Cable Truss System is a flexible support system that can be installed in-cycle much faster and easier than existing truss supports.
Uncompromising Strength
Our research indicates that the design capacity of the IN-ROOF system should be limited to the ultimate strength of the cable being used (30 tons).
Simplicity - Only Three Basic Components

SDS Square Head Cable Bolts
SDS Square Head Cable Bolts can be used in every application where traditional cable bolts are used and where standard ground support is marginal or inadequate. Common application areas include: gate roads, bleeders, recovery rooms, set-up rooms, intersections and other mine areas where additional support is indicated.
Added benefits of this cable bolt with its innovative square head indented strand design are improved resin/strand mechanical interlock, eliminated or reduced bulbs, lower hydraulic pressure during insertion and better encapsulation.
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. The TCB System provides compression into the roof and ensures “top-to-bottom” tensioning of the cable, which places the anchorage higher in the roof structure to eliminate “anchorage shock” during loading.
Common application areas include: tail gates, bleeders, recovery rooms, set-up rooms, head gates, intersections and other mine areas where longevity and additional support is required.
Minova leads the way with cable bolt technology that can be installed within development stages.
It incorporates various truss anchor types and two different truss shoe assemblies along with a cable cross member in concert with threaded U-bolts for re-tensioning without requiring hydraulic power, thus making it a very strong and highly flexible system.
Truss systems have evolved and currently many systems incorporate high strength cables as a key component to add flexibility and capacity. One such system is the Minova U-Bolt Hybrid Truss System.
