Top 5 benefits of retrofits

Cut costs: Reduce your operating budget with more efficient components and lower maintenance costs from common fleet parts.
Extend machine life: Delay large investments in new bolters and jumbos by replacing vital components — such as a mining rock drill — that do the hard work.
Boost productivity: Whether Montabert drifters that can increase penetration rates by 8.5% or Timberock feeds with fast loading 9-bolt carousels, our retrofits help you get results.
Promote zero-harm: Lower drifter noise, fewer bit changes, strong rock bolting anchorage and less maintenance fosters a better work environment and minimizes hazards.
Retrofit your way: Our component experts will work closely with you to address your unique needs and help you get the most from retrofitting your fleet.
