Abstract
The invention relates to the chassis of a public works machine, constituted by a central frame joined with two side-members. After assembly with the two side-members, the central frame constitutes a girder comprising a lower plate, an upper plate, two cross-plates, and two longitudinal plates, which plates are joined together as follows: each cross-plate to the upper plate, to the lower plate and to each one of the longitudinal plates, and the upper plate and the lower plate to the longitudinal plates, so as to constitute a closed compartment. The invention finds an application in the construction of a chassis for a mechanical shovel.
Claims5
Supporting chassis for a public works machine, such as a hydraulic shovel, consisting of a central frame joined with two side-members, wherein after assembly with the said side members, said central frame constitutes a girder comprising:
- a substantially horizontal external lower plate,
- a substantially horizontal external upper plate,
- two substantially vertical external crossplates, and
- in the area of the side-members, two external longitudinal plates, these various plates being joined together as follows:
- each external cross-plate to the upper plate, to the lower plate, and to each one of the longitudinal plates,
- and in addition, the upper plate and the lower plate are individually joined to each one of the external longitudinal plates,
- so as to constitute at least a closed compartment, delimited on the one hand, by the external upper and lower plates, and on the other hand by the two external crossplates,
- an upper-structure or turret mounted on the central frame for rotation with respect to the chassis, about a substantially vertical axis, by means of a shroud integral with the said central frame, the said shroud being mounted on a shroud support constituted by a sheet of metal extending between the external lower and upper plates of the central frame and which is connected to said plates.
