Heavy Vehicle Mechanics are qualified to repair and maintain the engines and components of large vehicles and engines. Depending on their practical experience and qualifications, these mechanics will specialise in particular vehicles and/or stationary engines; anything from mobile cranes, drilling rigs, trucks and bulldozers to specialised agricultural or mining machinery.

With a Heavy Vehicle Mechanic Apprenticeship you are qualified to undertake a number of diagnostic processes associated with the vehicles and/ or engines your host employer exposes you to. You could find yourself working for the government maintaining bus and transport fleets; working for a national Road Transport company managing their road worthy assessments; or subcontracting to mining or construction companies repairing and maintaining generators, pumps, compressors and drilling rigs.

This trade requires a four year apprenticeship. MIGAS will facilitate your practical work placement with one of our quality host employers. In addition to on-the-job training, we will assist you with enrolment through a Registered Training Organisation to complete your certification. With MIGAS you will be fully supported throughout the duration of your placement by a Field Officer and by the wider MIGAS Apprentices and Trainees community.
