FIELD: mechanical engineering; control systems of load-lifting cranes.
SUBSTANCE: control signals of load-lifting crane actuators are formed depending on movement of handle of microprocessor control device by crane operator in directions for executing different crane operations and on results of comparison of parameters of crane operation measured by pickups with tolerable values. Setting of parameters of control signals is provided by microprocessor calculator at provision of safe operation of load-lifting crane and convenience for operation of crane operator depending on crane operation, direction and value of shifting control device handle and parameters of crane operation.
EFFECT: improved efficiency of crane, safety of crane in operation and convenience in operation for crane operator.
