Elphinstone Mechanical Services

What Elphinstone Mechanical Services does

Elphinstone Mechanical Services (EMS) is a privately held, family-owned Western Australian heavy equipment maintenance and field services provider founded in 2005 (with some sources citing 2006). The company delivers on-site mechanical, electrical, welding, line boring, and shutdown support for mobile plant equipment, primarily to major mining operators and mining contractors across Australia. Its service stack spans Mobile Plant Maintenance (drill rigs, excavators, haul trucks, dozers, loaders), Field Service Support, Rostered Site Support, HME Shutdowns, Fast Tracked (24-hour) Emergency Maintenance, Automotive Electrical, Welding and Fabrication, and mobile Line Boring, with additional dedicated offerings in Rail Maintenance and Road Transport Maintenance. Service delivery relies on trade-certified technicians (mechanics, fitters, auto-electricians, welders, line borers, boilermakers) deployed in mine-spec compliant field service vehicles equipped with specialised diagnostics, with EMS handling all personnel onboarding (inductions, PPE, medicals, police clearances, insurance) on behalf of clients.

EMS operates from three primary locations — Belmont (Permetropolitan headquarters), Karratha (Pilbara workshop), and Paget/Mackay (Queensland east-coast regional office) — and supports operations across metro Perth, the Pilbara, the Goldfields, the Northern Territory, and east-coast Queensland. The business is run by founder Shane Elphinstone (Business Development Manager / Managing Director) and Jody Elphinstone (General Manager – Operations), supported by an Operations Manager and Finance Manager. Revenue is generated through professional-services contracts, with quote-based, multi-year pricing structured around scope, duration, location, and skill requirements. The customer base is concentrated in tier-1 mining (Rio Tinto, BHP, Roy Hill, CITIC Pacific Mining) and major contractors (Barminco, Emeco, MACA), and EMS is CAT 3 certified and holds ARC license AU27415. In May 2026, EMS announced a strategic partnership with SSH Group to scale WA service capacity.
