Single Phase Hoist

EOT Crane design and costs depends upon Duty Class of cranes. Crane class duty are chooses based on average load intensities and number of cycles. On the other hand, the classification all hoists by the International Organization for standardization (ISO), European Federation Standard (FEM) and Hoist manufacturer Institute (HMI) is according to more rigorous requirements, which include number of starts and maximum running time per hour. 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.
