METHOD OF CONTROLLING ELECTRICALLY DRIVEN LIFTING MECHANISM BRAKE

摘要

FIELD: transport.;SUBSTANCE: invention relates to brakes for lifting mechanisms. For control purposes, true power transducer is used to measure motor consumed true power with lifting mechanism serviceable brake disengaged. Then, brake is engaged for short-term to measure true power with engaged brake. Difference in said magnitudes are compared to reference value. If both are equal, brake is considered serviceable.;EFFECT: higher safety.;4 cl, 3 dwg
