ANSI E1.4-1-2022
Entertainment Technology - Manual Counterweight Rigging Systems
Scope
Design, construction, inspection and maintenance requirements for manual counterweight rigging systems: the fly systems in most proscenium theatres, arbors, rope locks, loading galleries and all.
Notes
The document behind how a counterweight house is meant to be built and looked after. If a venue survey finds a fly system with no inspection history, this is the reference to hold it against.
