CMAA Requests for Interpretation

The Crane Manufacturers Association of America (CMAA) does not provide: design guidance, design critique, advice, or comments. Any inquiries of this nature, if received, will be declined. However, CMAA Members may be interested in providing such technical support and you are encouraged to visit CMAA members for their contact information.

CMAA will respond to a request to interpret a specific element of a CMAA specification if your request is supplied on company letterhead and is provided via fax or as an emailed attachment identifying the specification and the specific paragraph(s) in question.

Such requests will be considered as an Action Alert Inquiry (AAI) and will be submitted to the CMAA Engineering Committee for interpretation and a response. Only written inquiries on interpretation and applicability of CMAA Specifications 70 and 74 will be given a response by the CMAA Engineering Committee.

Please send your inquiries related to CMAA specifications as outlined above to:
