Does the motor have a higher duty cycle if lifting a light load?
I would like to know if this hoist can be run at a higher duty cycle if it is lifting a very light load (30lbs). For example, could it be run for a few hours with a lifting time of about 5 seconds and 10 seconds rest?

on Northern Industrial Tools Electric Hoist - 220/440-Lb. Capacity
This electric hoist has a 20% duty cycle regardless of the weight of the load(max capacities of 220 lbs./single line and 440 lbs./double line).

Yes, duty cycle actually tells your the motor will heat up and kick out the thermal safety switch at or about 20% of ten minutes while lifting a maximum load. So, the amount of work the hoist does generates heat, the lighter the load the lower the heat put out by the motor windings. Also, it the ambient temperature is high or low that will affect the length of time you can operate within the motors thermal safety range also.
