Technical Rigging: Speedlining and Span Rigging

Similar to an “Advanced Rigging” seminar.
This one day seminar will provide participants with training and practical use of specialized equipment and techniques employed in safe rigging techniques used in arboricultural operations. By the end of this seminar attendees will be able to identify hazards and risks associated with rigging and tree removal. They will be able to identify and inspect rigging equipment that is in compliance with the work to be performed, as well as the equipment’s limitations. A basic knowledge of physics, forces and loading involved with rigging will be provided, along with rigging methods that can mitigate those forces. The second half of the day will feature the advanced rigging techniques of span rigging and speed lining. When each method is used, what gear is involved, how to set the system up and operate it.
