In this course, trainees learn how to be safe and productive with one of the true, all-weather workhorses of mining and heavy construction: the articulated haul truck. When conditions are adverse or when you've got a worksite with close quarters requiring tight turns, or you need a hauler that can go where others can't, it's tough to beat the articulated haul truck.
- Lesson 1 covers the basic components of a typical six-wheel-drive articulated dump truck (ADT), including its powertrain, braking systems, transmission and areas of limited visibility.
- Lesson 2 explains how to claim the machine and do a walk-around inspection of a typical ADT.
- Lesson 3 focuses on loading methods, and covers topics such as factors to keep in mind as operators approach the loading area, truck positioning, loading from a bench, spotting methods for over-the-rail and through-the-tail loading, drive-by loading and loading from a wheel loader.
- Lesson 4 explores the most important situations operators are likely to face on the haul road, how to minimize tire damage and extend tire life, how to travel down a grade with a fully-loaded truck.
- Lesson 5 is all about unloading the truck, including how to approach the dump area, basics of dumping the load, dumping with and without a spotter, roll-over accidents, dumping on an incline and how to spread a load when dumping.
