FIELD: transport.
SUBSTANCE: invention relates to pick-and-place equipment, particularly, to protection of cranes with telescopic booms against turnover and overloads. Magnitudes normalised relative to tolerable magnitudes are used as info and comparable values. This allows reducing the tolerable loads varying in the field of cargo characteristics to constant value defining the range of crane loads to be expanded by multiplication by constant factor. Proposed method allows setting the zone of crane dangerous operation whereat automatic drive deceleration device switches on to decelerate the drive to zero rpm at constant load.
EFFECT: higher reliability and safety.
