Two Draft Powered Rigging Standards in Public Review

Two of the several documents that make up the E1.6 project for powered rigging systems in the entertainment industry are now available for public review on the PLASA website.

BSR E1.6-1 - 201x, Entertainment Technology - Powered Hoist Systems, deals with powered winches that are not serially manufactured electric chain hoists. These are most often wire rope winches that are installed as part of a powered rigging system. The document is intended to establish requirements for the design, manufacture, inspection, and maintenance of powered hoist systems for lifting and suspending loads in theatres and other places of public assembly. It is in public review through July 11.

BSR E1.6-4 - 201x, Portable Control of Fixed-Speed Electric Chain Hoists in the Entertainment Industry, covers portable control systems for single-speed electric chain hoists. These systems are most often used to control one or more chain hoists being used to fly equipment or scenery in shows or events being done in arenas and convention centers. It is in public review through June 27.
