FIELD: mechanical engineering; load-lifting cranes.
SUBSTANCE: invention relates to control systems of load-lifting cranes. It contains electronic unit, actuating unit and load-lifting crane operating parameters transmitters. Electronic unit is made in form of digital computer and control elements connected to computer as well as indicators, storage unit and data input-output device connected to inputs of actuating unit and to load-lifting crane operating parameters transmitters. System contains also additional control members on crane control handles and connected to electronic unit input-output device, and digital computer is made for changing data transmitted to indicators and parameters or functions of disconnection of load-lifting crane mechanism according to coordinate protection system depending on signals from additional control members.
EFFECT: improved safety of crane in operation owing to reduced time of reaction of crane operator under critical situations, improved convenience of control and operating conditions for operator.
