TRAINING COURSE:
Rigging, Part 1
Course Category: Transmission and Distribution
Course description: The purpose of this course is to teach the fundamentals of overhead rigging. The topics covered include three basic elements of safe rigging, rope, knots and knot tying, use of a handline, and use of block and tackle. The course also introduces approaches to performing some basic rigging tasks. At the conclusion of this course, participants should have a basic understanding of how to plan a rigging job, how to inspect the equipment used on a job, how to tie basic knots commonly used in rigging, how to hang and use a handline, and how to hang and use a block and tackle. Participants should also be able to calculate the mechanical advantage of a block and tackle and identify the basic parts of a rope.
