scope:

This standard establishes requirements for the design, manufacture, installation, inspection, and maintenance of powered hoist systems for lifting and suspension of loads for performance, presentation, and theatrical production.

This standard does not apply to the structure to which the hoist is attached, attachment of loads to the load carrying device, or systems for flying people. Excluded are welded link chain hoists, and manually powered hoists, including auxiliary drill operation. (See Annex note.)

The provisions of this standard are not intended to prohibit any design, materials, or methods of fabrication, provided that any such alternative is at least the equivalent of that described in this standard in quality, strength, and effectiveness. (See Annex note.)
