Abstract
This invention relates to a public works machine comprising a frame, a working attachment, a counterweight and auxiliary jib moving above the counterweight and coupled to the working attachment. This auxiliary jib is provided with a guide member for a flexible connection means, said member being disposed above the counterweight, whilst such a connection means connects the counterweight to that part of the working attachment which is movable with respect to the part directly coupled to the frame by abutting on the guide member, constituting a link for handling said counterweight. One application of the present invention is the providing of a high power hydraulic shovel with a dismountable counterweight.
