The braking arrangement has an input shaft for connection to a drive shaft of the system. A brake device for the input shaft is urged towards operation by a spring released by an electric actuator. The input shaft is coupled to a flywheel by step-up gearing so that the moment of inertia applied by the flywheel to the input shaft is more than 17 times that of the remainder of the arrangement. Acceleration of the drive shaft under an external force is thereby reduced, as is its rotational travel during application of the brake.
