Heavy Duty Equipment Technician Red Seal Exam Prep · Question
An articulated haul truck with an unladen weight of 35,000 kg and rated capacity of 25,000 kg needs additional traction for a specific worksite. The decision is made to add calcium chloride solution as tire ballast to the drive axle tires. If each of the four drive tires requires 400 litres of ballast, and the solution weighs approximately 1.2 kg/litre, what is the total added weight to the drive axle from the ballast?
Total added weight = (Number of tires) x (Volume per tire) x (Weight per litre) = 4 tires x 400 litres/tire x 1.2 kg/litre = 1920 kg. This increases traction bu

Question: An articulated haul truck with an unladen weight of 35,000 kg and rated capacity of 25,000 kg needs additional traction for a specific worksite. The decision is made to add calcium chloride solution as tire ballast to the drive axle tires. If each of the four drive tires requires 400 litres of ballast, and the solution weighs approximately 1.2 kg/litre, what is the total added weight to the drive axle from the ballast?
Answer options: ✅ 1,920 kg
- 1,600 kg
- 4,800 kg
- 2,400 kg
Correct answer: 1,920 kg
Explanation: Total added weight = (Number of tires) x (Volume per tire) x (Weight per litre) = 4 tires x 400 litres/tire x 1.2 kg/litre = 1920 kg. This increases traction but must be carefully calculated to avoid exceeding axle load limits.
