Improvements are made to prior tractors supported and driven by a rubber track having bogie wheels to increase the boom lifting capacity. The improvements include a main subframe having a loop-like structure which has a center section extending under the tractor frame midway between the front idler wheels and rear drive wheels, two end sections extending outwardly, one end section supporting the drawworks and the other end supporting the fairlead. A rigid cross member extends from the fairlead to the drawworks and is positioned above the tractor frame beneath the cab.
Cette invention concerne des améliorations relatives aux tracteurs à chenilles en caoutchouc et roues en bogies, destinées à augmenter la capacité de levage de la flèche. Il s'agit d'un faux châssis en forme de boucle passant sous le châssis du tracteur de manière que sa partie médiane soit centrée entre les roues avant de retour et les roues arrière motrices et que les deux extrémités dépassent de part et d'autre du tracteur. L'une des extrémités porte le treuil et l'autre le guide-câble. Un élément transversal rigide passant par dessus le châssis du tracteur, sous la cabine, relie le treuil et le guide-câble.
