Large-size raise boring machines for holes ranging from 2.4 to 6.0 m (8-20 ft.) in diameter.

The Robbins 91 and Robbins 123 rigs are powerful raise-boring rigs with a modular design for easy transport when weight or size limitations can be a serious concern. These rigs drill holes from 2.4 to 6.0 m (8-20 ft.) in diameter and can be relied on in a variety of applications. At Atlas Copco, we strive to construct high-quality machines that are easy to set up, operate and maintain – and our Robbins 91 and 123 rigs are no exception. These machines are built to serve and built to last.


Features & benefits

  • Power you can depend on The powerful 500-kW electric motor drives the reamer to penetrate the hardest rock.
  • Easy maintenance and transport The gear box is installed in a removable barrel, allowing the derrick to be split into smaller, more transportable components.
  • Steadfast and efficient Standard functions include anti-jamming, auto makeup and the gradual ramp-up of speed and torque.
