Entertainment Technology - Manual Counterweight Rigging Systems
It's scope covers permanently installed, manually operated counterweight systems of stage rigging hardware for the raising, lowering, and suspension of scenery, lighting, and similar loads. The systems illustrated in the Figures section describe common arrangements of systems used over performance areas. It also applies to variations of manual counterweight rigging, including rope and sandbag systems. This standard applies to rigging hardware and basic functional requirements only, and not to the structure from which it is supported. While not part of this standard, building structural capacity for the intended loads shall be considered in the design and application of rigging systems.
