The invention provides an electric transport vehicle which is equipped with a non-excitation operation type electromagnetic brake and can properly control the electromagnetic brake. An electric transport vehicle is provided with an electromagnetic brake of a non-excitation operation type. The electromagnetic brake has an electromagnetic coil. An electric transport vehicle is provided with a brake control circuit. The brake control circuit outputs a first control signal and a second control signal in response to the release condition being satisfied. An electric transport vehicle is provided with a signal processing circuit. The signal processing circuit outputs a cancellation signal in response to the first control signal and the second control signal being received. An electric transport vehicle is provided with a drive circuit. The drive circuit supplies a current to the electromagnetic coil in response to the release signal being received.
