Regarding the Load-Time Factor and the Starting Frequency
In case of the Bando wire rope hoist is set, the Load-Time factor is set at 40% and the Starting Frequency is set at 240 times /hour for the repetitive operation.
Load-Time Factor = ((Total of the time when the motor is live with electricity in a severe working condition)/60 minutes)× 100
Starting Frequency = Starting frequency per hour in an severe working condition
