Pro Tips from the Field

Wisdom from experienced Articulated Dump Truck operators.

1

Always grease the articulation joint and steering components thoroughly. This is a high-wear area and proper lubrication is critical.

2

Pay attention to tire pressure. Maintaining the correct pressure improves fuel efficiency, reduces tire wear, and enhances stability.

3

When operating in dusty conditions, check the air filter frequently and clean or replace it as needed. A clogged air filter can significantly reduce engine performance.

4

Listen for unusual noises. ADTs are complex machines, and unusual noises can be an early warning sign of a problem. Investigate any strange sounds promptly.

5

Keep the machine clean. Regularly washing the truck helps prevent corrosion and makes it easier to spot leaks and other problems.

6

Before starting the engine in cold weather, use a block heater to warm the engine oil and coolant. This will make starting easier and reduce engine wear.

7

When parking on a slope, always engage the parking brake and chock the wheels. ADTs can roll easily if not properly secured.
