Crane and hoist duty motors are most suitable for demanding applications where intermittent duty drives are required. These are duty-type rated motors, which require a high starting torque with a low starting current. Crane and hoist duty motors have to withstand frequent start-stops and reversal operations.
The term, ‘duty’, defines the load-cycle to which the machine is subjected, including, if applicable, starting, electric braking, no-load and rest de-energized periods, and including their durations and sequence in time. We offer a wide range of duties such as S1, S2, S3, S4, S5, S6, S7, S8 and S9, which comply with the IS 12824 standard.
