WEIGHT OVERLOAD PROTECTION WITH MAGNETEK G+ MINI DRIVE
Weight overload protection automatically limits the amount of weight a hoist can pick up. Typically this is done with a calibrated load cell or a slip clutch in the hoist. This can also be accomplished with a variable frequency drive which controls the hoist motor.
Recently we have successfully employed the Load Check II feature on G+ Mini hoists. This feature can be used to limit the capacity of the hoist to its full load capacity or to a lesser load if desired. In order to implement, a known weight is suspended from the hoist and then the drive is calibrated through simple command inputs at the drive keyboard.
