For the past 60 years, the CMAA (Crane Manufacturers Association of America) has published standardized guides for the selection of suitable cranes and crane equipment. These guides and specifications take into account a few key points to help buyers make the right match:
-The service that the system will be used for
-The frequency of use
-The speed required to match process parameters
-The buyer’s budget
The CMAA includes a detailed checklist for buyers to complete while they begin the selection process with a crane manufacturer. The checklist asks if key components of the crane are in compliance with the CMAA’s quality, safety, and value specifications. A “Crane Inquiry Data Sheet” will help narrow down the field to facilitate the perfect match of crane and buyer.
There are also specific service classifications so that the most economical crane can be purchased. They are Class A (Standby or Infrequent Service,) Class B (Light Service,) Class C (Moderate Service,) Class D (Heavy Service,) Class E (Severe Service,) and Class F (Continuous Severe Service.) Single girder cranes meeting Specification 70 can only be classified in categories A through D. Guides are available for Single Girder cranes, Multiple Girder cranes, and Below the Hook Lifting Devices.
