Abstract

L'invention concerne un dispositif servant à démolir une construction présentant une paroi circulaire, telle qu'une cheminée ou une tour de refroidissement, et comprenant une première poutrelle (1) à plusieurs bras, une deuxième poutrelle (2) à plusieurs bras, un palier rotatif (3) reliant de façon pivotante la première et la deuxième poutrelles l'une par rapport à l'autre, et au moins un chariot (6, 7) pouvant se déplacer sur au moins un des bras de la poutrelle, ce chariot pouvant être déplacé et arrêté de façon sélective dans le sens de la longueur du bras et présentant un palier pourvu de galets de roulement (14a, 14b) et de friction (15a, 15b) conçus de sorte qu'un basculement du chariot (6, 7) par rapport au bras dans une première position relative provoque l'accrochage des galets de friction (15a, 15b) et du bras, afin d'arrêter le chariot (6, 7), et qu'un basculement dans une deuxième position relative provoque un contact des galets de roulement (14a, 14b) avec le bras et le dégagement des galets de friction (15a, 15b) par rapport au bras, ce qui déclenche la translation du chariot (6, 7).
