This Standard establishes performance requirements for hand chain manually operated chain hoists for vertical lifting service involving material handling of freely suspended (unguided) loads using welded link type load chain as a lifting medium with one of the following types of suspension: (1) hook or clevis; (2) trolley. It is applicable to hoists manufactured after the date on which this Standard is issued. Differential pulley and self-locking worm drive type hoists are not covered in this Standard. 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; (5) hoists used for the purpose of drawing both the load and the hoist up or down the hoist’s own load chain; and (6) hoists used for marine and other applications as required by the Department of Defense (DOD). The standard includes an appendix on Hand Chain Manually Operated Chain Hoists used in marine and other applications as required by the Department of Defense (DOD).
