This training outline for heavy duty tiremen, one in a series of eight outlines, is designed primarily for company training foremen or supervisors and for trainers to use as an industry-wide guideline for heavy equipment operator training in open pit mining in British Columbia. Intended as a guide for preparation of lesson plans both for classroom and on-the-job training activities, this outline is divided into eight modules. Each module is based on 3 to 13 objectives. For each objective, key points and procedures are outlined. Module topics are basic safety and operating rules, communications, preparation of the equipment for tire changes, remove the tire from the equipment front and rear, replace the tires on the equipment front and rear, tire removal from the rim assembly, install tire on rim assembly, and special assignments. A skill profile chart is attached. (YLB)
