Frequently Asked Questions

  • What is a mine spec fit-out?

    A mine spec fit-out refers to the installation of safety and compliance equipment on vehicles or machinery to meet the entry requirements of mining or civil worksites. This can include items like battery isolators, fire extinguishers, reflective tape, call signs, wheel chocks, seatbelt alarms and more. Each mine site may have its own set of specifications, so fit-outs are usually customised for each project.

  • What vehicles need to be mine-spec compliant?

    Any vehicle or machine entering a mining or high-risk worksite typically needs to be mine-spec compliant. This includes light vehicles (like utes), trucks, excavators, graders, rollers, and other mobile plant. Even machines used temporarily on-site may need to meet certain safety requirements before being allowed entry, especially for shutdowns or audits.

  • Can mine spec fit-outs be done on-site?

    Yes – many providers offer mobile mine spec fit-outs, which means the equipment is installed at your location or depot rather than transporting vehicles off-site. On-site fit-outs save time, reduce downtime and allow multiple machines to be prepped quickly for compliance. Mobile technicians bring all the necessary tools, parts and knowledge to complete the work efficiently and to standard.
