FIELD: transport machine building.
SUBSTANCE: group of inventions relates to the field of transport machine building, in particular to parking brake devices for vehicles, preferably for industrial vehicles. Parking brake device includes brake cylinder with spring-loaded power accumulator, electrically controlled first valve device designed so that depending on electric control signal air release and/or air inlet to cylinder with spring-loaded power accumulator can be started. Parking brake device also includes a switched second valve device having a pneumatic control input and an electric control input, which is made to start air bleed from brake cylinder with spring-loaded power accumulator, when pneumatic control input has pneumatic pressure that is less than predetermined threshold value, and when electric current is not available at electric control input.
EFFECT: higher reliability of device is achieved.
