Rock Bolts – Bolt Fittings
- Used for Sling System with the 15.2mm Cable Bolt.
The Cable Sling Tension Block optimises the performance of the Cable Bolt by eliminating premature failure due to stress raisers. The twisting of the block when the system is under tension induces these stresses. The factors that contribute to the relief of the stress are:
1. The length of the block. The longer the block, the less twisting results when the system is under load;
2. The radius of curvature of the cable. The greater the radius of curvature, the greater area over which the stress is spread. The pipe yields as the load increases, forming a curve.
- Can be either supplied black or galvanized.
