Der Straßenferliger nach der Erfindung arbeitet folgendermaßen: Die Antriebsmotor^ 90 fur die Rader 25 und 25 A der beiden Fahrböcke 11 und 12 sind mit einer Fernbedienung ausgestattet, und weiten Fernbedienungen sind für die Rüttler und d.e Motor-Generator-Einhcit 86 vorgesehen. Die Motoren 90 können mit verschiedener Geschwindigkeit und auch in beiden Richtungen laufen.The road worker according to the invention works as follows: The drive motor 90 for the wheels 25 and 25 A of the two trestles 11 and 12 are equipped with a remote control, and other remote controls are provided for the vibrators and the motor-generator unit 86 . The motors 90 can run at different speeds and also in both directions.

Rüttelbohlen sich schräg zu den Fahrböcken einstellen können. An jedem Ende der Platten 70 sind eine oder mehrere sich abwärts erstreckende Hallerungen 71 vorgesehen, die von oben in Schraubenfedern 72 eingreifen. Unten ruhen die Schraubenfedern 72 auf an den Fahrböcken fest angebrachten Stützplatten 73, 74 und 75. Jede der Stützplatten weist eine «der mehrere Halterungen 76 auf, die von unten in die Schraubenfedern 72 eingreifen.Vibrating screeds can be set at an angle to the trestles. One or more downwardly extending hallways 71 are provided at each end of the plates 70 and engage coil springs 72 from above. At the bottom, the coil springs 72 rest on support plates 73, 74 and 75 which are firmly attached to the trestles. Each of the support plates has one of the plurality of holders 76 which engage in the coil springs 72 from below.

Der Querbalken 13 zwischen den Fahrböcken 11 xo und 12 kann jeweils an der oberen Seite des horizontalen Schenkels 50 jedes Teiles 22 befestigt sein. Eine U-förmige Halteplatte 78 umfaßt den Querbalken 13 an jedem Fahrbock. Schenkel 79 und 80 der Halteverringert wird, können erforderlichenfalls ein oder mehrere Teile der Laufstegplanke 14 abgenommen werden.The crossbeam 13 between the trestles 11 xo and 12 can each be attached to the upper side of the horizontal leg 50 of each part 22 . A U-shaped retaining plate 78 encompasses the crossbeam 13 on each trestle. Legs 79 and 80 of the holding device is reduced, one or more parts of the catwalk plank 14 can be removed if necessary.

Eine Motor-Generator-Einheit 86 ist auf dem waagerechten Schenkel 50 des Teils 22 befestigt. Der von der Motor-Generator-Einhcit erzeugte elektrische Strom wird unter anderem zur Speisung der Rüttler und der Antriebsmotoren 90 verwendet.A motor-generator unit 86 is fastened on the horizontal leg 50 of the part 22. The electrical current generated by the motor-generator unit is used, among other things, to feed the vibrators and the drive motors 90.

Der Antriebsmotor 90 ist auf dem V-förmigen Teil 21 jedes Fahrbockes montiert und weist ein Untersetzungsgetriebe 95 auf.
