INTRODUCING HMI
Founded in 1956, The Hoist Manufacturers Institute (HMI), an affiliate of Material Handling
Industry, is a trade association of manufacturers of overhead handling hoists. The products of its
member companies include hand chain hoists, ratchet lever hoists, trolleys, air chain and air rope
hoists, and electric chain and electric wire rope hoists.
HMI operates through committees with programs and policies reviewed and adopted by the
membership with representation from each member company. Its many activities include an active
engineering committee. HMI is represented on a number of standards developing committees and
actively supports the development and certification of safety standards by the ANSI consensus
method.
Our Members
HMI member companies are recognized as the leading authority and the principle resource in the
Hoist Industry. The HMI members are concerned, conscientious manufacturers affiliated in an
industry association to provide voluntary standards for the mechanical, structural and electrical
design of hand chain hoists, ratchet lever hoists, trolleys, air chain and air rope hoists, and electric
chain and electric wire rope hoists and to formulate guidelines for the proper use, operation and
maintenance of that equipment.
Our Association
HMI is a member driven organization. To qualify for membership a company must manufacture or
as a partial manufacturer of overhead hoists has engineered and designed its own overhead hoists
and assembled continuously the major hoist components for at least a three-year period prior to its
application for membership.
Member companies of HMI meet regularly to review, discuss and revise the standards for design,
performance and proper operation. HMI member companies have committed to the development,
maintenance and publishing of industry standard specifications.
Additionally, HMI has prepared, published and distributes Training, Inspection and Maintenance
recommendations that are available to all hoist users, such as the Hoist Operators Manual, Hoist
Inspection and Maintenance Personnel Manual, Manually Lever Operated Hoist Inspection and Hoist
Maintenance Personnel Manual, and the Manually Lever Operated Hoist Operators Manual.
The Occupational Safety and Health Administration (OSHA) recently announced an alliance with the
Monorail Manufacturers Association (MMA), the Crane Manufacturers Association of America (CMAA)
and the Hoist Manufacturers Institute (HMI). The purpose of this alliance is to provide monorail
systems, crane and hoists owners and operators with information, guidance, and access to education
and training resources that will advance their workplace safety and health.
Member companies participate in a requisite number of regularly scheduled meetings which among
other things further the ongoing process of revising and updating today's standards to meet the
ever-changing demands of technology and the modern industrial environment.
