FIELD: mechanical engineering; load-lifting machinery.
SUBSTANCE: invention relates to control devices of tower crane mechanisms electric drives. Proposed device contains control unit and electric drive control unit, unit to determine operating conditions and state of crane, unit to convert analog signals into digital signals and back, and unit to check condition of electric drives. Control unit is connected by first two-way communication channel with converter unit, by second two-way communication channel with unit determining operating conditions and state of crane. Electric drive control unit is connected with electric drive condition check unit and converter unit, and the latter is connected with electric drive condition check unit.
EFFECT: improved safety and reliability of tower crane in operation.
