FIELD: mechanical engineering; load-lifting cranes.
SUBSTANCE: invention relates to control and protection of load-lifting cranes. Method provides forming of image of working process, checking of position of load-gripping member or load in process of crane operation, and forming of control signal by at least one of crane actuating devices basing on results of checking. Said checking is provided by microprocessor calculator by processing and analyzing the image, as a result of which distance from load-gripping member or load to object or obstacle or to human in working zone of load-lifting crane is determined. Revealed distance is compared with set minimum threshold level. Then warning signal is shaped automatically, or control signal to operate actuating device and prevent movement of load-gripping member or load towards object, obstacle or human.
EFFECT: improved safety of crane in operation with due account of overall dimensions of lifted load and operation of slingmen.
