DS421 Cable bolter

Sandvik DS421 is a self-contained cable-bolting rig for rock reinforcement in underground mines and tunnels with small and medium cross sections. The full bolting cycle can be operated by one person working safely under the canopy or in a soundproof, air-conditioned cabin.


  • On-board cement mixer, cement bag platform, or optional cement silo and steel strand reel, make the rig autonomous for longer than one shift
  • Daily and routine checks are done with feet on the ground for increased safety
  • Electric controls and good ergonomics enable safer and faster operation
  • Flexible installation sequence increases efficiency
