History
Leading crane manufacturers founded the Electric Overhead Crane Institute, or EOCI, in 1927 to promote standardization of cranes in both quality and performance, which is the root of CMAA. After publishing specifications in 1949 and 1961 of EOCI 61, CMAA’s Engineering Committee continued to propose specifications of CMAA 70, CMAA 74, CMAA 78, the last of which are Standards and Guidelines for Professional Services Performed on Overhead and Travelling Cranes and Associated Hoisting Equipment. Re-released in 2003, CMAA engineering committee published the Crane Operators Manual, as well as the Operational Guide for Lifting Devices in 2006. Members meet twice a year to update and review its publications.
