ABSTRACT:
A machine for distributing ballast on a ballast bed supporting a track comprises a machine frame supported on the track by undercarriages, the undercarriages having wheels making point contacts with the track and the contact points defining a reference plane, chutes arranged on the machine frame and spaced from each other in a direction extending transversely to the machine frame, each chute having a discharge end for downwardly discharging ballast, and a vertically adjustable wiper unit downwardly projecting from the discharge end of each chute towards the track and extending the chute. The wiper unit comprises a drive for adjusting the wiper unit relative to the discharge end, and defines an inlet opening associated with the discharge end of the chute and an outlet opening defining a wiper edge, the wiper edge extending parallel to the reference plane.
