FIELD: mechanical engineering.
SUBSTANCE: according to proposed method of supporting crane operator to provide safe operation of load-lifting crane, operating parameters of crane are measured and processed and information is shown on display for necessity of taking measures to eliminate emergency situation. Data base is created additionally concerning combination of operating parameters of crane at different loads and spatial positions of boom or load-gripping member giving rise to danger at crane operation and said data base is kept on crane. Forecasting of appearance of emergency situation is provided by means of computer with use of data base and, when necessary, by means of mathematical model of crane, and additional measures taken by crane operator to prevent trouble are shown on display.
EFFECT: improved safety of crane operation and operating conditions for crane operator.
