New Powered Rigging Standard Project: Electric Chain Hoist Control

  • The BSR E1.6 project to develop an American National Standard for powered theatrical rigging systems has a new project and part to the standard: E1.6-4, Control of Serially Manufactured Electric Chain Hoists Used in the Entertainment Industry. The E1.6 document has been broken into parts to facilitate its development and to better match the expertise of the people writing it.
  • This newest part is an offshoot of the BSR E1.6-3 project, Selection and Use of Serially Manufactured Electric Chain Hoists in the Entertainment Industry. That project is to specify how chain hoists can be used safely in entertainment applications, which are very different from the applications for chain hoists in factories and materials handling situations. It has became clear that chain hoist control system safety is a complex topic, so the Rigging Working Group, at its meeting on 13 July 2007, voted to give control systems their own E1.6 part and development project.
