The purpose of this course is to introduce trainees – particularly those people who have had little or no previous exposure to mining – to key pieces of heavy equipment most often used on mine sites and large construction projects. These work sites are busy places and may expose workers to a variety of hazards and dangers. Trainees need to have a clear understanding of how these machines work and interact, and common safety hazards to be aware of when working around them. It is usually a prerequisite to most other equipment courses.
- Lesson 1 introduces seven types of earthmoving machines and explains how each plays a part in moving material in the mine: crawler dozers, hydraulic excavators, motor graders, wheel loaders, rear-dump rigid frame haul trucks, articulated frame haul trucks and hydraulic face shovels.
- Lesson 2 teaches trainees about key safety principles, including due diligence, engineered controls, administrative controls and personal protective equipment (PPE).
- Lesson 3 explains how heavy machinery responds to being started in cold weather and what can be done to transition it to operating temperature with the least amount of machine stress. It also outlines important steps that must be followed when shutting down a machine after it has been working hard.
