Instructor: Lester Kenway, Trail Services LLC, PTBA Member Company
This 1-Day workshop will explore the safe use of Griphoist ® wire rope machines and their applications for moving materials for building trails. An introductory indoors presentation will review the available Griphoist products, safety guidelines, estimating loads, tools and accessories, as well as photos and descriptions of both simple and highly complex systems.
The outdoor segment of the workshop will be hands-on use of rigging systems to familiarize students with the safe operation of the hoists and rigging equipment. We will move materials via pulling loads with single and multi-line systems. “High lines” will be constructed by the class to move heavy loads through the air , down slopes, up slopes and across side hill terrain. Dynamometers will be available to measure and visualize forces at play. This workshop is appropriate for trail builders of all experience levels.
