Abstract

L'invention concerne une machine de nettoyage de tube et de canal (1) pourvue d'un système de mâchoires de serrage (3) monté en rotation et destiné à être amené en prise par serrage avec une spirale de nettoyage (10) pouvant être entraînée par la machine de nettoyage de tube et de canal (1). Le système de mâchoires de serrage (3) peut être amené en prise par serrage avec la spirale de nettoyage (10) à la suite d'un actionnement d'un levier à main (5) de la machine de nettoyage de tube et de canal (1). La spirale de nettoyage (10) est mise en rotation pendant le mode nettoyage de la machine de nettoyage de tube et de canal (1), un sens de rotation du mouvement de rotation du système de mâchoires de serrage (3) pouvant être inversé à la suite d'un actionnement d'un dispositif d'actionnement de sens de rotation (12). La spirale de nettoyage (10) ne peut être mise en rotation que lorsque le levier à main (5) est actionné et, lorsque le levier à main (5) est actionné, le dispositif d'actionnement de sens de rotation (12) est commuté à partir d'un état neutre soit dans un état marche à droite soit dans un état marche à gauche.
