Abstract

The invention relates to a supporting chassis for a working machine, constituted by a central frame assembled to two longitudinal side-members. Each side-member is essentially constituted by a metal sheet which is bent to form an overturned V and by a plate, closing off the said V, which is fitted to the lower ends of the sides of the overturned V. The invention finds an application as a supporting chassis for a hydraulic shovel.
