Aerial rigging is commonly practiced to different degrees by specialty fabricators, professional riggers, professional aerial artists, and amateur aerial artists. Most aerial circus equipment is built by a few fabricators around the world that build equipment specifically for the circus industry.
Aerial artists, both professional and amateur, often become riggers out of necessity. They generally learn to rig what they need.
WLA (Weak Link Analysis) is the process of systematically analyzing aerial rigging for the weakest link or links in the system. WLA is the most common process used by aerial riggers to assess and improve rigging. However, it is not the only system used.
