This Standard establishes performance requirements for electric wire rope hoists for vertical lifting service involving material handling of freely suspended (unguided) loads using wire rope with one of the following types of suspension: (1) lug (2) hook (3) trolley (4) base or deck mounted (does not include base-mounted winches of the type covered by ASME B30.7) (5) wall or ceiling mounted (does not include base-mounted winches of the type covered by ASME B30.7) This Standard is applicable to hoists manufactured after the date on which this Standard is issued. This Standard 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 the purpose of lifting or lowering people (5) hoists used for the purpose of drawing both the load and the hoist up or down the hoist\u2019s own wire rope (6) hoists used for marine and other applications as required by the U.S. Department of Defense (DOD) unless Nonmandatory Appendix A is invoked 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 operation.<\/p>\n
