Title: Method of handling a pivoting cab of a public works machine and a public works machine applying said method

Abstract: This invention relates to a method of handling the driver's cab of a public works machine, said cab being mounted to pivot on the frame (turret) of the machine and this machine comprising a working attachment, mounted on said frame, whose form may undergo a modification. The pivoting axis of the cab is substantially perpendicular to the plane of deformation of the working attachment, a zone of the cab distinct from the one where the axis is located is coupled, via a sling, to the working attachment and the deformation of the working attachment is controlled so as to displace said coupling zone thus pivoting the cab as desired. One application of the present invention is the realization of a high power hydraulic shovel.
