An installation for cleaning ballast of a track includes a plurality of vehicles having machine frames supported on on-track undercarriages. Two shoulder clearing chains, positioned opposite one another relative to a transverse direction of the track, take up ballast located in a shoulder area adjoining sleeper ends, an endless clearing chain follows the shoulder clearing chains relative to a working direction of the installation and is to be guided around the track for taking up ballast underneath the track. A screening installation, conveying devices for transporting ballast, and a ballast introduction device are also provided. A first conveying device transporting ballast to the screening installation is associated with the shoulder clearing chains. A second conveying device transporting ballast to a processing unit is associated with the endless clearing chain. A third conveying device transporting ballast to the screening installation is associated with the processing unit.

A machine having a ballast take-up device for taking up ballast located underneath a track. The take up device has an endless clearing chain guided in a chain channel. In a connecting joint from a transverse channel to a transport channel. There is also a ballast deflector blade pivotable about a pivot axis. Arranged on the ballast deflector blade is a ballast conveyor, designed for ballast transport in the direction towards a pivot axis by means of a conveyor drive. With this, it is possible to expand the operating range of the ballast take-up device, as needed.

A machine for repairing a ballast bed has an undercutter that defines a direction of movement of the repairing machine, and a distributor for dividing a flow of ballast entering from the undercutter into a rear flow of exiting ballast and a separate front flow of exiting ballast. At least one rear screening machine is positioned behind the undercutter in the direction of movement and is fed by the rear flow of exiting ballast. At least one front screening machine is positioned in front of the undercutter and fed by the front flow of exiting ballast, and the distributor has a variator for varying the ratio between the separate first and the second flows of exiting ballast.
