From servicing the equipment to following preventative maintenance schedules; general condition inspections; reports to repairing any defects on the spot where possible.

Rig Rebuild Support

Rebuilding rigs is a large part of keeping your equipment on-site running reliably. We want to help you ensure your equipment is up to date with technology and compliant with mine site safety systems. We are passionate about keeping your rigs in top condition and assisting you in respect to the time targets you have set.

We can supply personnel to be in your workshop working alongside your maintenance crew, or on-site for site based overhauls.

  • Equipment modernisation
  • Installation of new valves, auxiliary hydraulics and improved control systems
  • Re-hosing rigs in a way that improves the ergonomics of the rig, increasing the life of hoses and cables.
  • Rebuilding Mud and Grout pumps

Mine site compliance is an area of maintenance that is simple, though it will cost you more time due to the small things that are flagged in mobilisation inspections and site audits. We are here to help reduce the downtime and make sure your equipment is site ready, audit ready and safe.

When there are any issues, we are here to assist with planning, timeframes and solutions to get you on site, and drilling.

  • Pre-mobilisation inspections for a smooth transition onto site
  • On-site audits to prepare for ongoing compliance inspections
  • Installation of safety systems such as interlocks, cut-outs and warning systems to comply with latest site requirements
  • Installation of guarding and barriers

Who Are We

Over a decade of experience in the drilling industry

Hey there, I’m Ben. I am the rig-fixing, guitar-playing, woodchopping extraordinaire, and I do it all with a smile on my face.

I started MOA Heavy Diesel in 2021. I noticed there was a gap in the industry, and I knew many more clients would benefit from high-quality workmanship and a holistic approach to drill rig and suite maintenance. I understand the drilling industry from both sides of the fence, having been a driller in the past.

I have worked in the Drilling industry for over a decade, and each day is an opportunity to lead with my expertise and help as many people as I can to continue to succeed in the Drilling industry with great asset availability and reliability.

When I’m not out there working on equipment or troubleshooting over the phone, you’ll find me honing my axes or training for the various Woodchops around WA!

I have always been known as the person that is always smiling and enthusiastic about what I do and its true! I really do have a true passion for the people and equipment that I get to work with and get great satisfaction from helping people fix problems.
