This service covers cranes which may be used in repair shops, light assembly operations, service buildings, light warehousing, where service requirements are light and the speed is low. Loads may vary from no load to occasional full rated loads with 2 to 5 lifts per hour, averaging 10 feet per lift.
CMAA SERVICE CLASS C AND D
Within the crane industry, there has been considerable confusion as to the definitions of CMAA C and D services, as well as HMI ratings of H3 and H4. In the past, Class C has been regarded as packaged hoist equipment, while Class D has been regarded as open deck machinery. As packaged hoist manufacturers increased the duty ratings of their hoists from H3 to H4, packaged hoists then began to be used for Class D service. In some cases, this has resulted in premature failures of Class D packaged hoists when operating in a Class D rating.
Crane Manufacturers Association Specification No. 70
defines Class C and D service as:
This service covers cranes which 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 which average 50 percent of the capacity with 5 to 10 lifts per hour, averaging 15 feet, not over 50 percent of the lift at rated capacity.
This service covers cranes which may be used in heavy machine shops, foundries, fabricating plants, steel warehouses, container yards, lumber mills, etc., and standard duty bucket and magnet operations where heavy duty production is required. In this type of service, loads approaching 50 percent of the rated capacity will be handled constantly during the working period. High speeds are desirable for this type of service with 10 to 20 lifts per hour averaging 15 feet, not over 65 percent of the lifts at rated capacity.
This type of service requires a crane capable of handling loads approaching a rated capacity throughout its life. Applications may include magnet, bucket, magnet/bucket combination cranes for scrap yards, cement mills, lumber mills, fertilizer plants, container handling, etc., with 20 or more lifts per hour at or near the rated capacity.
This type of service requires a crane capable of handling loads approaching rated capacity continuously under severe service conditions throughout its life. Applications may include custom designed specialty cranes essential to performing the critical work tasks affecting the total production facility. These cranes must provide the highest reliability with special attention to ease maintenance features.
