TRAINING COURSE:
Rigging, Part 2
Course Category: Transmission and Distribution
Course description: The purpose of this course is to teach rigging skills required for tasks often performed in line work. The course demonstrates how to rig to lift a conductor and how to rig to take the strain from a conductor at a dead end. Rigging to lift and move a piece of equipment and the use of a gin pole are also demonstrated. Safety is emphasized throughout the course. At the conclusion of this course, participants should have a basic understanding of how to rig to lift a conductor, how to rig to take strain at a dead end, how to lift and move a load, and how to use a gin pole. They should understand how to maintain safe working clearances around energized lines and how to avoid overloading rigging equipment.
