  • the detection of the interruption of the work operation and the interruption of the drive of the milling drum is carried out automatically.
  • the present invention has the advantage that the milling drum is not driven when it is not in the work mode and thus the energy consumption of the construction machine is reduced.

  • At least one operating parameter of the construction machine can be checked to detect the interruption of the working operation.
  • the at least one operating parameter of the construction machine which can be checked to detect the interruption of the working operation, can in particular be an actual operating parameter of the construction machine.

    caractérisé en ce qu'un dispositif de contrôle (15) détecte une interruption du régime de travail et, en cas de détection de l'interruption du régime de travail, émet un signal afin d'interrompre l'entraînement du tambour de fraisage (12), dans lequel le tambour de fraisage se trouve en régime de travail lorsque l'engin de chantier se déplace vers l'avant et le tambour de fraisage est en rotation et se trouve en prise avec le sol.
  11. Engin de chantier (1) selon la revendication 10, caractérisé en ce que le dispositif de contrôle (15) contrôle au moins un paramètre opérationnel de l'engin de chantier (1) afin de détecter l'interruption du régime de travail.
  12. Engin de chantier (1) selon la revendication 11, caractérisé en ce que le dispositif de contrôle (15), afin de contrôler l'au moins un paramètre opérationnel, requiert le paramètre opérationnel de l'engin de chantier (1) depuis le dispositif de commande (14) et/ou depuis des capteurs mesurant le paramètre opérationnel, et compare l'au moins un paramètre opérationnel requis à au moins une valeur limite prédéfinie.
  13. Engin de chantier (1) selon l'une des revendications 10 à 12, caractérisé en ce qu'un dispositif de transmission de force (13) est prévu afin de transmettre une puissance d'entraînement de l'unité d'entraînement (6) au tambour de fraisage (12), dans lequel le dispositif de contrôle (15) émet le signal d'interruption de l'entraînement du tambour de fraisage (12) vers le dispositif de transmission de force (13) ou vers le dispositif de commande (14) et le dispositif de transmission de force (13) interrompt l'entraînement du tambour de fraisage (12).
  14. Engin de chantier (1) selon l'une des revendications 10 à 13, caractérisé en ce que le dispositif de contrôle (15) détecte une interruption du régime de travail et n'émet le signal d'interruption de l'entraînement du tambour de fraisage (12) qu'après un délai prédéfini.
  15. Engin de chantier (1) selon l'une des revendications 10 à 14, caractérisé en ce qu'après l'interruption de l'entraînement du tambour de fraisage (12), le dispositif de contrôle (15) détecte si le régime de travail doit être repris et, en cas de détection de la reprise prévue du régime de travail, émet un deuxième signal afin d'entraîner à nouveau le tambour de fraisage (12).
  16. Engin de chantier (1) selon la revendication 15, caractérisé en ce que le dispositif de contrôle (15), afin de détecter la reprise prévue du régime de travail, requiert au moins un paramètre opérationnel de l'engin de chantier (1) depuis le dispositif de commande (14) et/ou depuis un dispositif de service (16) et/ou depuis des capteurs, et compare l'au moins un paramètre opérationnel à au moins une valeur limite prédéfinie.
  17. Engin de chantier (1) selon l'une des revendications 10 à 16, caractérisé en ce que le dispositif de commande (14) retarde la locomotion de l'engin de chantier (1) et/ou un abaissement du tambour de fraisage (12) jusqu'à ce que le tambour de fraisage (12) ait atteint une vitesse de rotation opérationnelle prédéfinie.
