Sandvik mobile bolters

Sandvik DM300 is a mobile bolter designed for the installation of strata support in place-change coal mining operations. This track-mounted machine offers a safe yet rapid way to install roof and rib support. It offers superior performance thanks to the ability to install a full row of roof bolts without tramming. Options include dedicated rib bolters that can operate from a common operator’s platform.


  • Walk-through design allows on-board access to consumable storage and offers protection from exposed ribs
  • Four dedicated roof bolters ensure productivity with full coverage of strata support plans
  • Large operator platform provides full protection from the roof and rib as well as safe and ergonomic access to all functions
