Abstract: This invention relates to a machine, in particular a construction machine and preferably a wheel loader or dumper, comprising a pump, an energy accumulator connected with the pump, which includes a first space which is gas-filled and which includes a second space which is designed such that in operation of the pump it is filled by a fluid delivered by means of the pump, wherein the gas contained in the first space is compressed, and comprising a hydraulic motor to be driven by means of the energy accumulator, wherein the energy accumulator is designed such that the ratio of the volume of the first space with fully loaded second space to the volume of the first space with non-loaded second space is >0.5.

Abstract: The present invention relates to a system for the automatic movement of material in a working area comprising at least one movable piece of equipment, wherein the system has a control for the automatic movement of the piece of equipment with an automatic recognition of obstacles. In accordance with the invention, the control has a first obstacle processing function which moves an obstacle in the working area automatically using the movable piece of equipment; and/or in that the control has a second obstacle processing function which automatically removes an obstacle from the working area using the movable piece of equipment.

Abstract: A drive arrangement for earth moving machines of simplified structure which allows ready access to the various parts thereof for servicing. The arrangement includes a controlled hydrostatic motor dispersed between a fluid power pump associated with the internal combustion engine of the machine and which is connected through its drive shaft to the universal drive shaft of the machine at a point between the rear wheel driving axle and the universal joint associated therewith.
