The invention relates to a parking brake device (1) comprising an electrically controllable parking brake circuit with a parking brake actuation device (36) that has at least one parking brake actuation element (37), which interacts with an electric parking brake value transmitter (39) and which can be actuated by the driver, and an electronic controller (14), to which a parking brake signal based on an actuation of the parking brake actuation element (37) is transmitted by the parking brake value transmitter (39). The electronic controller (14) controls a solenoid valve (10, 12) of a valve device (8, 18) on the basis of the parking brake signal, said valve device being connected to at least one spring accumulator brake cylinder (5) as the parking brake. The parking brake device also comprises a pneumatically actuatable parking brake circuit that is provided as a redundancy and has at least one pneumatic valve (72) which can be actuated by the driver and which pneumatically controls at least one pneumatically controllable valve (18) of the valve device (8, 18). According to the invention, the at least one pneumatic valve (72) is arranged and designed so as to be mechanically actuatable by the parking brake actuation element (37).
