Abstract

Un capteur mesurant la pression d'une barre de support sur un engin de nivelage à froid fournit un signal permettant de commander l'extension de la barre (22) afin de maintenir le contact entre le sol et cette dernière (22) dans l'éventualité d'un rebond. La rotation du cylindre de nivelage (21) est également interrompue en réponse à ce signal, et la reprise du fonctionnement du véhicule n'est permise que lorsque la pression de la barre de support es t suffisante pour permettre à l'opérateur de contrôler le déplacement du véhicule.
