17 ABSTRACT OF THE DISCLOSURE An escalator for transporting passengers between upper and lower landings. The escalator includes a fly- wheel, an overrunning clutch, and a fail-safe friction brake. The overrunning clutch and brake, when actuated applies a braking torque only when the escalator is moving such that it would transport passengers from the upper to the lower landing. The inertia of the flywheel and the braking torque of the brake are predetermined to provide the desired range of deceleration, when the escalator stops in either travel direction, regardless of load.
