Abstract
The invention relates to a supporting chassis for a working machine, having a central frame provided, on each side of its longitudinal middle plane, with an indentation, whose general concavity is transversely directed opposite the middle plane, and which is delimited by two transverse arms, each one including a substantially vertical cross-plate, and, further having two longitudinal side-members placed on either sides of the middle plane, substantially parallel thereto, the ends of the arms defining an indentation which constitutes the areas where the central frame is secured by welding to the corresponding side-member, each arm being secured to the side-member essentially by welding the outermost edge of the cross-plate of this arm to the side-member, and the invention finding an application in the production of a hydraulic bucket loader with strong chassis.
