Passively actuated braking system

A movement system includes a rail, a trolley, and a braking system. The trolley is movably attached to the rail and configured to support the payload. The braking system is operatively attached to the rail. The braking system includes a braking module having a base, operatively attached to the trolley, and a wheel assembly, operatively attached to the base. The wheel assembly has a shaft, a clutch, and a braking wheel. The clutch is rigidly attached to the shaft and configured for rotation with the shaft about the rolling axis. The braking wheel axially surrounds the clutch and is in continuous rolling contact with a surface of the rail. The clutch is configured to selectively allow rotation of the braking wheel relative to the shaft in only one direction of rotation to decelerate movement of the trolley along the rail.
