HIGH STRENGTH. FLEXIBILITY.
Cable bolts offer significantly higher strength compared to traditional bolts, along with unparalleled flexibility to accommodate the movements of the earth’s strata.
The Minova cable bolt range includes:
- Continuous roll or cut to length 15.2 mm
- Plain and bulbed cables
- Twin strand plain and bulbed cables
- Resin anchored 21.8 mm diameter Superstrand
- 50T fully bulbed strata cables
PLATES
- Flat plates
- Dome plates
- Other plate variations are available
ACCESSORIES
Accessories include various barrel and wedges to suit either 15.2mm cable bolts or a 21.8 mm cable bolt. Barrel and Wedges consist of either two or three triangular shaped wedges placed inside a case hardened cylindrical barrel. Used to secure plates to the rock surface and in some instances to provide pre-tension to a resin point anchored cable bolt.
Other accessories include grout, breather tube and several hole plugging products.

LOKSET RESIN CAPSULES
- The Lokset resin system provides rapid anchoring of the bolt to the surrounding strata. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components transforming the resin mastic into a solid anchor. Resin point anchoring and bulbs to assist resin capsule mixing.
Packaging
- Bolts are usually packaged in bundles of 50 or 100. Coiled or flat bundle options available.
