ASME HST-6 - Performance Standard for Air Wire Rope Hoists HST-6 - 2020

This Standard establishes performance requirements for air wire rope hoists for vertical lifting service involving material handling of freely suspended (unguided) loads using wire rope as the lifting medium with one of the following types of suspension: (1) lug; (2) hook or clevis; (3) trolley; (4) base or deck mounted (does not include winches of the type covered by ASME B30.7). (5) wall or ceiling mounted (does not include winches or the type covered by ASME B30.7). It is applicable to hoists manufactured after the date on which this Standard is issued. It is not applicable to: (1) damaged or malfunctioning hoists; (2) hoists that have been misused or abused; (3) hoists that have been altered without authorization of the manufacturer or a qualified person; (4) hoists used for lifting or supporting people; or (5) hoists used for the purpose of drawing both the load and the hoist up or down the hoist's own wire rope. HST-6-2020 includes a new Nonmandatory Appendix B, which provides guidance and recommendations for providing mechanical spark resistance for hoists covered in this standard when such hoists are used in hazardous (potentially explosive) locations, as defined by NFPA 70 National Electric Code. The requirements of this Standard shall be applied together with the requirements of ASME B30.16. Please also refer to ASME B30.16 for requirements pertaining to marking, construction, and installation; inspection, testing, and maintenance; and operations. HST-6-2020 includes a Nonmandatory Appendix which provides performance requirements beyond those cited in ASME HST-6 for air wire rope hoists for use in marine and other applications as required by the Department of Defense (DOD). When used with the rest of HST-6, this Standard replaces the requirements of MIL-H-2813 for air wire rope hoists. Table of Contents
