DYWIDAG Cable Bolt
Flexible reinforcement system with post-tensioning option.
- Ground Support
The DYWIDAG Cable Bolt is a pre-tensioned, bulbed cable tendon designed to be installed as a long rock bolt. Used in underground hard rock mines, DYWIDAG Cable Bolts help ensure a safe working environment by increasing rock mass stability.
Manufactured from 19 wire strands having a nominal diameter of 21.8mm cross-section, the cable bolts are capable of being post-tensioned at the face to withstand with a post-tensioning force of up to 25 tons. The system uses mixed resin to fill the borehole. The top end of the bolt provides a very efficient anchorage by using a unique combination of a spiral resin mixer and a choice of up to 3 bulbs.
High-strength system for permanent or temporary reinforcement, with tensioning possible
Available in lengths up to 10 meters, and can be cut to any length for easy on-site length adjustment
Unique combination of a spiral resin mixer to ensure thorough combination of resin and hardener
Anchorage strength of the resin-grouted top end of the bolt exceeds bolt tensile strength in typical rock conditions
Easy to handle and adapt to confined working spaces
Can be used in combination with other support systems such as shotcrete, mechanical bolts, or grouted rebar for complete flexibility
