La chaîne trancheuse (3) est protégée par un carter (3a) de protection de chaîne trancheuse (3).The slicer chain (3) is protected by a slicer chain guard (3a) (3).

Le bâti ou corps (1) porte latéralement, extérieurement au carter (3a) de protection de la chaîne trancheuse, un boîtier d'engrenage (5) protégé par un couvercle (5a) de protection de la transmission.The frame or body (1) carries laterally, externally to the casing (3a) for protecting the slicer chain, a gearbox (5) protected by a cover (5a) for protecting the transmission.

Le bâti ou corps (1) comporte également, du côté opposé au couvercle (5a) de protection de la transmission, un couvercle (4a) d'accès à un moteur hydraulique d'entraînement (4) alimenté en fluide hydraulique par la machine de bâtiment ou travaux publics non représentée.The frame or body (1) also comprises, on the opposite side to the cover (5a) for protecting the transmission, a cover (4a) for access to a hydraulic drive motor (4) supplied with hydraulic fluid by the control unit. building or public works not shown.

Dans le dispositif selon l'invention présentant un ensemble de fraisage comportant une chaîne trancheuse (3) et deux têtes (2) latérales de fraisage, la largeur de travail de l'ensemble de fraisage (2, 3) correspond sensiblement à la dimension transversale du moteur hydraulique (4) d'entraînement.In the device according to the invention having a milling assembly comprising a slicer chain (3) and two lateral milling heads (2), the working width of the milling assembly (2, 3) substantially corresponds to the transverse dimension. the hydraulic drive motor (4).
