    Wenn bezüglich der Schwenkbarkeit der Kübelhälften 15 um die Achsen 28 kein Anschlag vorgesehen ist, der ein Schwenken der Kübelhälften 15 gegenüber der Kübeltragkonstruktion nach unten begrenzt, ergeben sich auch bei Unebenheiten im Fahrbahngrund immer einwandfreie Auflastverhältnisse bezüglich der Stützräder 30.If with respect to the pivotability of the bucket halves 15 Axes 28 no stop is provided, the pivoting of the bucket halves 15 limited compared to the bucket support structure, result perfect load conditions even with unevenness in the road surface with respect to the support wheels 30.

    Anstelle der Stützräder 30 können auch Raupenlaufwerke eingesetzt werden.Instead of the support wheels 30, caterpillar drives can also be used become.

    Unterseitig zu dem Kübel 11 des vorderen Straßenfertigers 1 kann auch ein Fahrwerk etwa in Form von Stützrollen angeordnet sein, so daß dieser als eingeklappte Einheit unabhängig vom Straßenfertiger transportiert werden kann.Underneath to the bucket 11 of the front paver 1 a chassis can also be arranged in the form of support rollers, for example that this as a folded unit regardless of the paver can be transported.

    Die Querfördereinrichtungen 18 sind zweckmäßigerweise wechselweise entsprechend einer Auflastmessung an den Kübelhälften 15 antreibbar. Die Steuerung kann manuell oder automatisch erfolgen.The cross conveyors 18 are expediently alternating driven according to a load measurement on the bucket halves 15. The control can be done manually or automatically.
