Title
(EN) LOG SKIDDING VEHICLE'S PIVOTABLE ARCH STRUCTURE
(FR) STRUCTURE ARQUEE PIVOTANTE POUR UN VEHICULE DE TRAINAGE DE BILLES DE BOIS
Abstract
(EN) A pivotable arch structure (18) having an integral log bunk (30) is pivotable at one end (P) thereof relative to a main frame (15). The log bunk (30) includes several longitudinally arranged bunk webs (36) which are bolstered by laterally arranged support beams (38) connected thereto. A bumper (40) is arranged adjacent the end of the bunk webs (36) near the pivot axis (22). The longitudinal disposition of the bunk webs (36) promotes longitudinal log travel thereon while the bumper (40) guides logs initially engaged therewith in a direction to promote their subsequent engagement with the bunk webs (36). The longitudinally arranged bunk webs (36) also provide high operator visibility for various pivotal positions of the arch structure (18).
(FR) Une structure arquée pivotante (18) ayant un logement solidaire (30) pour les billes peut pivoter à une extrémité (P) par rapport à une structure principale (15). Le logement des billes (30) comprend plusieurs joues de logement longitudinales (36) qui sont soutenues par des poutres de support latérales (38) reliées aux joues. Un buttoir (40) est disposé adjacent à l'extrémité des joues (36) à proximité de l'axe de pivot (22). La disposition longitudinale des joues de logement (36) améliore le déplacement longitudinal des billes tandis que le buttoir (40) guide les billes dans une direction facilitant leur engagement ultérieur avec les joues de logement (36). Les joues de logement longitudinales (36) offrent également une bonne visibilité à l'opérateur, la structure arquée (18) pouvant prendre plusieurs positions de pivotement.
