The CEMA Engineering Conference meets each June. Its purpose is to develop, and keep relevant, the technical documents that support the needs of the Conveying Industry. It has been doing so since 1934. The following pages summarize most, if not all, of the technical products that it has developed in support of the needs of the Conveying Industry Members attending the upcoming Engineering Conference will continue to preserve and enhance that proud legacy.
Developed and Maintained by the General Bulk Handling Section Members CEMA STANDARD No. 102, "CONVEYOR TERMS & DEFINITIONS" When the Conveyor Equipment Manufacturers Association (CEMA) was formed in 1933, one of the first things they discovered that there were no common terms and agreed upon definitions for any equipment or products in the industry. It took them eight years to develop the first edition, just in time for World War II. The common terms and definitions were influential in helping standardize the conveying and other material handling activities in the war mobilization and in the industrial expansion after World War II. They have since been adopted for use nationally and internationally and have contributed to the common worldwide language of the global material handling and distribution system we enjoy today. This standard has indeed made a difference. CEMA BROCHURE No. 201, "SAFETY LABEL BROCHURE" This document was developed to begin the CEMA Standardized Safety Label Program. Danger, Warning, and Caution Safety Labels were developed to identify known potential hazards associated with human operation in and around conveying equipment.

Newest items include addition of CEMA Class "F" Idlers. PULLEYS CEMA STANDARD No. B105.1, "SPECIFICATIONS FOR WELDED STEEL CONVEYOR PULLEYS WITH COMPRESSION TYPE HUBS" These pulleys have a continuous rim and two end discs, each with a compression type hub to provide a clamp fit on the shaft. This ANSI/CEMA Standard provides recommended load ratings, dimensional information, and criteria for selection of welded steel conveyor pulleys with compression type hubs. CEMA STANDARD No. 501.1, "SPECIFICATIONS FOR WELDED STEEL WING PULLEYS" Welded steel wing pulleys have a number of steel wing plates that extend radially from the longitudinal axis of two compression type hub assemblies and are equally spaced about the pulley circumference. This ANSI/CEMA Standard provides recommended load ratings, dimensional information, and criteria for selection of welded steel wing pulleys. Bulk Conveyors, Bulk Conveyor Accessories See Above.
