Cable Bolts incorporate much higher strengths than traditional bolts do, providing a much greater range of flexibility that adjust to the movement of the earth’s strata.
Cable Bolts are applicable where standard ground support is marginal or inadequate. 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.
Significant Advancement in Roof Support Technology
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.
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
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.
