Abstract

L'invention concerne un véhicule mobile de ramassage de déchets comportant une paire de brosses avant de coins (32, 34) montées de façon indépendante sur des bras articulés (46) de façon que les brosses (32, 34) puissent être déplacées en cas d'obstacle afin d'éviter de les (32, 34) endommager (32, 34) ou d'endommager l'objet représentant l'obstacle. Un système de recirculation d'air est utilisé afin de prolonger la durée de vie du filtre final de sortie, et il est possible d'utiliser un sac à déchets imperméable (133) afin d'évacuer le contenu d'un sac de collecte primaire en renfort tissé (131) .
