The Rigging for Trail Work Workshop is for anyone interested in the use of Griphoists and rigging systems for trail work, regardless of prior experience. Over the course of three days, this workshop will cover rigging fundamentals, safe setup, and operation of Griphoist ground and high line systems for situations involving pulling, lowering, lifting, and moving heavy loads on and off of the ground.

Rigging in trail work entails using hoists, wire ropes, and mechanical advantage systems for moving heavy loads. High line operations utilize hoists, wire ropes, elevated spar locations, belays, hauling, and mechanical advantage systems with a variety of slings, blocks, shackles, belay, and anchoring equipment. Over three days, participants in this workshop will learn how to safely design, setup, and operate ground and aerial rigging systems, and will get hands-on experience. This will include learning about the different pieces of equipment, their working load limits (WLL), tree climbing and anchor building, how to identify and quantify forces, and safe operational practices.

Please bring lunch, water, snacks, and clothing appropriate for being outdoors, as well as this required personal protective equipment (PPE), which will be worn at all times unless otherwise noted:

  • Hard Hat (provided at workshop if needed)
  • Eye Protection (provided at workshop if needed)
  • Full Leather Boots
  • Long Work Pants
  • Long Sleeve Shirt (for specific jobs)
  • Leather Gloves (when handling wire rope)
  • Latex-coated Gloves (optional, better grip when wet)
