CEMA’s HistoryCEMA 90th anniversary logo

The story of the Conveyor Equipment Manufacturers Association (CEMA) dates back to 1933, when the idea of an organized, professional association representing the interests of the materials handling and elevating machinery manufacturers was first discussed.  During its 90-year history, CEMA has grown and developed to respond to the ever-changing environment in which its members do business, while remaining true to its original goals and purposes:

  • To promote the common interests of CEMA members and the conveyor industry of the Americas; and
  • To promote standardization of design, manufacture, and application on a voluntary basis and in such a manner as will not impede the development of conveying equipment and component parts or lessen competition.

At CEMA’s three in-person and one virtual meeting each year, member companies discuss new developments in conveyor design, technology, and application.  Drawing upon the efforts and expertise of our member companies, CEMA provides the conveyor industry with standards, technical publications, safety labels, and safety information.

CEMA works closely with other organizations, such as the Material Handling Industry of America and the Association of Rubber Products Manufacturers, with a shared interest in materials handling, voluntary standards, and business in general.  CEMA also maintains contact with government agencies whose activities concern the conveyor equipment industry, keeping a finger on the pulse of federal legislation and regulations affecting the industry, which is then reported to our membership through our Government Affairs Committee.

With an ever broadening membership base and an unwavering commitment to its original puposes, CEMA continues as the voice of the conveyor industry of the Americas, enjoying international prestige and stature throughout the industrial community.
