Demag Cranes & Components, Cleveland, Ohio, is the first manufacturer to receive the Hoist Manufacturer Institute’s (HMI) certification for its DC line of electric chain hoists. HMI is a trade association affiliated with the Material Handling Industry of America (MHIA). HMI certification requires a stringent and thorough evaluation, by an independent third-party professional engineer, of the product’s technical design and specifications.
Product design and test data was reviewed and certified to ensure Demag’s DC chain hoists conform to North American standards that include the Performance Standards for electric chain hoists ASME HST 1-1999 reaffirmed (2004); Safety Standards for overhead hoists ANSI B30.16; and National Fire Protection NFPA 70 Article 610.
Also required for certification were availability of product safety, installation, operation, maintenance, and spare parts manuals; the availability of product training and technical support; life-cycle spare parts availability; and qualified service and repair capabilities. Demag’s HMI certification indicates that the company’s DC electric chain hoists meet or exceed every applicable requirement in the identified standards. Its purpose is to instill confidence in the product bearing that mark and in the licensee providing that product.
