The 2014 National Electrical Code has a number of paragraphs affecting electric chain and wire rope hoists. Some of these paragraphs are subject to varying interpretations. Therefore, acting through the electrical engineering subcommittee of the HMI engineering committee and with the approval of the HMI Board of Directors, the Hoist Manufacturers Institute has developed and authorized the publication of the consensus contained within this pamphlet. It is hoped that this HMI Consensus will be mutually helpful to users, manufacturers and sellers of electric chain and wire rope hoists. For specific commentary with respect to individual brand hoists, users and sellers should contact the manufacturer(s) of their electric chain and wire rope hoist(s).
