scope:

This standard establishes the minimum requirements for the design, inspection, and maintenance of Portable Fixed-Speed Electric Chain Hoist Control Systems in the Entertainment Industry.

Other elements connected to Portable Chain Hoist Controllers such as the chain hoist, the electrical power system, the rigging, and the rigged load may be covered by other standards or codes of practice, and may also be required to be inspected by, or reviewed by, a local authority having jurisdiction.

This standard is focused on control systems that are based on discrete signals that have a direct effect on the controlling relays, contactors, and indicators, without the aid of a Programmable Electronic System (PES).

For information regarding PES equipment the reader is directed to the ESTA Technical Standards Documents web page to locate the appropriate documents.

This version of the E1.6-4 Standard is not intended to be applied retroactively to equipment manufactured prior to the publishing date of this revision.
