(FR) EXCAVATRICE DE TRANCHEES ROTATIVE
Abstract: front page image
(EN)A rotary trench excavator comprises a propulsion unit (1) hingedly connected to a movable boom (2) carrying the working organ which consists of a system of rotors (9-11). Each rotor (9-11) is provided inside it, to ensure its rotation, with a supporting frame (6) having supporting (7) and guiding (8) rollers and a driving mechanism. To enable turning through 180° of each of the rotors (9-11) individually or the system of rotors as a whole in the position of forward or reverse excavation, an additional frame (4) is connected to boom (2) of the excavator and to each of the rotors (9-11) by means of dismountable fixing units (13-26).
(FR)Une excavatrice de tranchées rotative comporte une unité de propulsion (1) reliée de manière articulée à une flèche mobile (2) portant l'organe de travail qui consiste en un système de rotors (9-11). Chaque rotor (9-11) renferme, afin d'assurer sa rotation, un cadre de support (6) possédant des rouleaux de support (7) et de guidage (8) ainsi qu'un mécanisme d'entraînement. Afin de permettre la rotation sur 180° de chacun des rotors (9-11) individuellement ou du système de rotors dans son ensemble dans la position d'excavation dans le sens de la marche ou en sens inverse, un cadre additionnel (4) est relié à la flèche (2) de l'excavatrice et à chacun des rotors (9-11) au moyen d'unités de fixation (13-26) démontables.
