Abstract

The proposal is for an earth-moving machine, e.g. a cable dredger, hydraulic dredger, ditcher, loading shovel or the like with a bogie (3) possibly connected to moving gear (2) on which a superstructure (5) pivotable about a vertical axis is secured on which there is working gear (11) integral with a counterweight (9), in which the superstructure (5) is divided into a stationary section (10), possibly rotatable about the vertical axis (7) and a section (10) pivotable about a horizontal axis (13) and the pivotable section (10) is directly or indirectly coupled to the working gear (1).
