Abstract: The present invention relates to a work machine having a fuel cell drive comprising a fuel cell and determination means for determining the load demand of the fuel cell, wherein the work machine has a plurality of electrical consumers that are directly or indirectly connected to the fuel cell for the purpose of obtaining electrical energy, wherein the determination means are configured such that the power requirements of at least two of the electrical consumers enter into the determination of the load demand of the fuel cell.

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: The present invention relates to a work machine, preferably a wheeled loader, having a bucket which is movable via lifting arms having at least one lift cylinder, on the one hand, and which is pivotable via a tilt mechanism actuable via at least one tilt cylinder, on the other hand, having a selectable fully automatic or semi-automatic bucket filling process in which the bucket is movable by a superimposition of the tilt movement of the bucket and of the lift movement of the lifting arm for the filling. In accordance with the invention, material-dependent target tilt cylinder speed values and target lift cylinder speed values stored in a memory are associated with the measured lift cylinder pressure values and/or the pulling force for the regulation of the bucket filling process.
