ESTA's Technical Standards Program Full E1.6 Suite is Open for RevisionTwo Rigging Working Group standards have been announced as open for revision: E1.6-3, Selection and Use of Serially Manufactured Chain Hoists in the Entertainment Industry, and E1.6-4, Portable Control of Fixed-Speed Electric Chain Hoists in the Entertainment Industry. The first two parts of the E1.6 suite for powered hoist systems, E1.6-1 and E1.6-2, were both opened for revision last year, so now all four parts are open for revision to address outdated references, correct errors, include new technologies, and stay coherent as a suite of standards. E1.6-3, Selection and Use of Serially Manufactured Chain Hoists in the Entertainment Industry, establishes minimum safety requirements for the selection and use of serially manufactured electric link chain hoists having capacity of two tons or less in the entertainment industry. This part does not address the design or maintenance of these hoists. The standard is being revised to address outdated references, correct errors, and include new technologies. E1.6-4, Portable Control of Fixed-Speed Electric Chain Hoists in the Entertainment Industry, covers portable control systems for fixed-speed electric chain hoists used in the entertainment industry. This part four document is the final installment of the ANSI E1.6 suite of powered entertainment rigging standards as it currently exists. It is being opened for revision to address changes from other parts of the suite under revision.
