INNOVATIVE SIMPLICITY

With their own practical drilling experience the Mincon Rock Drill engineers used innovative simplicity to design a series of drilling units that were easy to maintain and service. This engineering methodology designed a series of machines that are built to last: 

  • Engineered simplicity also means components are stronger and more durable. 

  • Maintenance requirements are reduced with fewer wearable items and moving parts.

  • Off-the-shelf parts and spares can be utilized from local suppliers, Lowering maintenance and operating costs.

  • The Rock Drill R405 is a powerful, restricted access drill rig for low head room applications.
