Service and preventive maintenance of heavy vehicles
Why planned maintenance keeps trucks on the road
For a transport company a truck is a tool that makes money when it is running — and costs money every hour it is standing still. Therefore working as a truck mechanic is largely about preventing breakdowns before they happen. Preventive maintenance is the core task.
§Preventive rather than reactive
Reactive maintenance is repairing when something has broken down – often roadside, expensive and at the worst possible time. Preventive maintenance is planned inspections where wear is detected and remedied before it leads to breakdown. It increases operational reliability, extends the vehicle's lifespan and improves safety for both driver and other road users.
§Areas in a service inspection
- 01Motor: oil and filters, cooling system, belts and visible leaks.
- 02Brakes: linings, discs/drums, air tightness and spring brakes.
- 03Wheels and tires: wear, pressure and tightening of wheel bolts.
- 04Steering and suspension: play, leaks and worn joints.
- 05Electrical: lights, warning lamps and battery condition.
- 06Hydraulics and superstructure: oil level, hoses and function of lift/tip.
§Legal requirements and documentation
Heavy vehicles are subject to rules on inspection, weight and equipment, and the driver's driving and rest time is recorded by a tachograph. As a mechanic you must know the requirements for what you work on and document completed work properly. Good documentation is both a legal requirement, proof of quality and helpful at the next inspection.
§The mechanic's role in operations
The good truck mechanic does not just see the individual error, but the entire vehicle's operational safety. By catching incipient wear, advising on upcoming repairs and performing inspections thoroughly, you keep the fleet on the road. It is a role where expertise is directly translated into transport being able to function.
