Look for training programs that prepare you to become an anchor rigger, which are available through companies and agencies such as the U.S. Forest Service or Total Solutions Group. Expect the course to last one to a few days.
Study topics such as the principles of chain hoists, lifting points on structures and the proper way to conduct rope work when rigging to the grid in roof steelwork. Also, review information regarding handling and running chains through motors, putting together trusses and using shackles and slings with hoists. Purchase helpful industry books such as the "Riggers Bible" by Robert Leach, which covers technical information related to anchor rigging.
Go over the laws governomg work in the anchor rigging industry, such as the Health and Safety at Work etc. Act of 1974 and the Work at Height Regulations of 2005. Practice actually hanging chain motors, rigging simple two-leg bridles and de-rigging equipment. Go over the principles of bridle trigonometry as well as asymmetrical and symmetrical bridles. Learn how to place anchors appropriately so a load's tension can be managed safely as well.
Also, get experience with communicating with hoist operators and directing individuals to make their equipment more slack or tight, which you will have to do if you are the anchor rigger in charge on a job site. Build your skills with working in a team environment.
Master how to perform simple load calculations and work at heights using personal protective equipment. In addition, study how to maintain your machines by cleaning component parts and performing routine maintenance duties. Get practice with lifting heavy items, as an anchor rigger job position will require you to push, pull, lift or carry heavy objects.
Ask your training program to help you find local internship opportunities or entry-level job opportunities to help you to build your skills in the anchor rigging industry.
