ABSTRACT:
A hydraulically controlled and driven dredge, in which the pumps for delivering the driving fluid for the bucket wheel drive are equipped with output controls for controlling the fluid delivery in conformity with the encountered digging resistance and that a control conduit branched off from a pressure conduit leading to a hydraulic motor for driving the bucket wheel is connected to an output limiting valve located in a control circuit which includes an adjusting device connected through conduits to a manually operable control for varying the delivery and the delivery direction of the pump for actuating the hydraulic motor for pivoting the upper structure of the dredge. The fluid delivery of the pumps to the hydraulic motor employed for driving the track laying mechanism being conveyed to the hydraulic motor for driving the bucket wheel when the track laying mechanism is not to be operated.
