  • Patent number: 7604300
    Abstract: The present invention relates to a dump truck or large mining truck, comprising a dump body for the transport of overburden or the like, a first hydraulic circuit having a first pump device for the actuation of the dump body as well as a second hydraulic circuit having a second pump device for the actuation of a steering and/or of a braking device of the dumper truck chassis and/or an auxiliary truck element. In accordance with the invention, the first, second and/or a further hydraulic circuit having are connected to one another by a valve device which is controlled by a control device such that the plurality of hydraulic circuits cooperate in an unloading mode and actuate the dump body together and, on the other hand, the hydraulic circuits work separately in a travel mode so that the second hydraulic circuit and/or any further hydraulic circuit is separated from the dump body and its actuator device.
