Why Choose Us?

1. We Solve Problems

We love to solve problems and think on our feet for our clients. We treat each job with the utmost respect for time and its value.

2. Trade-based Knowledge

Along with our trade-based knowledge, we also understand the facets of mobile earthmoving equipment from the operator’s and crew’s point of view. This is a massive advantage when diagnosing and improving your equipment for functional use.

3. High-quality Workmanship

We pride ourselves on high-quality workmanship and giving a great experience for both YOU and your site representatives.

4. Risk Management Strategy

We treat our clients’ equipment as though it is our own. We are always keeping an eye out for things that may pose a threat to future downtime, so we can RESPOND to issues instead of REACTING.

5. We Are Innovative.

We love innovation. We are always looking at ways to improve your equipment in an ever-changing industry.

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 operating. 

Pre-mobilisation inspections for a smooth transition onto site. On-site audits to prepare for ongoing compliance inspections.

Installation of safety systems, NSW MDG compliant such as mine speecification, cut-outs and warning systems to comply with latest site requirements. Installation of guarding and barriers.
