Mid-size raiseboring machines for holes ranging from 1.5 to 3.1 m (5-10 ft.) in diameter.

Robbins 73 rigs are the sturdiest, most widely sold raiseboring rigs in the world. These medium-sized machines drill holes from 1.5 to 3.1 m (5-10 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 73 rigs are no exception. Robbins 73 machines are built to serve and built to last.


Features & benefits

  • Designed for expert drilling The Robbins 73 in-line drive system provides balanced thrust loads to improve cutting and minimize vibrations and wear.
  • Fast and easy setup Robbins 73 rigs require a smaller drilling pad and fewer tie-down bolts. Setup is quick and easy.
  • Steadfast and efficient Standard functions include anti-jamming, auto makeup and the gradual ramp-up of speed and torque.
