Cranes), there are six (6) different classifications of cranes, each dependent on duty cycle. Within the CMAA Specification is a numerical method for determining exact crane class based on the expected load spectrum. Aside from this method, the different crane classifications, as generally described by CMAA, are as follows:
Aug 28, 2013· CMAA Crane classification and its comparison with other classification are given below. There are six different classifications of cranes by CMAA based on the duty cycle of crane. Class A (Standby or Infrequent service) – This crane is the lightest crane as far as duty cycle is concerned.
This service class covers cranes that may be used in machine shops or paper mill machine rooms, etc., where service requirements are moderate. In this type of service, the crane will handle loads that average 50 percent of the rated capacity with 5 to 10 lifts per hour, averaging 15 feet, not over 50 percent of the lifts at rated capacity.

CMAA traces its roots to the Electric Overhead Crane Institute, known as EOCI, which was founded in 1927 by leading crane manufacturers of that time to promote the standardization of cranes as well as uniform quality and performance. The voluntary association was incorporated as the Crane Manufacturers Association of America, Inc. in 1955.
Jun 09, 2017· Two cranes with an equal capacity and span could vary in price as much as $100,000 because high duty cycle cranes (Class D, E, or F) require specialized components like the hoist, end trucks, motor, bearings, and controls. Low duty cycle cranes can get away with more standardized and economical components—resulting in significant cost savings.
