§Study guidance — lorry mechanic

Work with heavy vehicles is similar to cars but the forces, weight and consequences are far greater. Emphasize safety and systematicity: compressed air, hydraulics and large wheels are safe when handled correctly and life-threatening when they are not. Understand the systems so you can find faults and perform preventive maintenance with insight.

Important concepts to understand

• 01Air brakes, spring brake and the fail-safe principle.
• 02Hydraulics: pump, valve, cylinder, tank and filter.
• 03Preventive maintenance versus reactive repair.
• 04ABS/EBS and brake control on heavy vehicles.
• 05Legal requirements for training in epoxy and isocyanates; product number and safety data sheets

Good habits and preparation

Always empty compressed air and hydraulic systems of pressure before separating parts, and mechanically support lifted vehicles and parts. Use manufacturer's torques and procedures, and document completed work thoroughly. Always remember that what you send out on the road weighs many tonnes — your care is part of traffic safety.

Where can you read more

Use the school's teaching material, manufacturers' workshop data and the applicable regulations for heavy vehicles as primary sources. Vocational schools' truck and transport programmes and industry organisations in transport and automotive publish technical guidance. Daily consultation with experienced colleagues and your master is an important learning source.
