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.
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:
