A work machine, more particularly a wheeled loader, having a cab for the operator of the work machine, wherein the work machine has a drive which can be operated with hydrogen and that one or more tanks for receiving hydrogen are provided, wherein components for receiving the tanks are provided, wherein the tank or tanks are arranged below the cab and, when the work machine is viewed from above, next to the cab of the work machine, wherein the components for receiving the tanks do not have a direct mechanical connection to the cab, and that an armor is provided which partially or completely surrounds the tank.

Work machine

The present invention relates to a work machine, in particular a wheeled loader, having a cabin for the operator of the work machine and having an engine room arranged behind the cabin, wherein the work machine has a drive that is operable with hydrogen; and in that one or more tanks for the reception of hydrogen are present, with the tank or tanks being arranged in a hydrogen fuel system behind the cabin and above the engine room.

The present invention relates to a mobile work machine, in particular to a wheeled loader, having a hydraulic circuit, having a pump for conveying a hydraulic medium through the hydraulic circuit, and having at least one control block having an inflow control edge and an outflow control edge for controlling the flow of the hydraulic medium, wherein the work machine has a working tool and a cylinder for actuating the working tool and wherein the cylinder has an outflow and in inflow for the hydraulic medium, and wherein the outflow is in fluid communication with the outflow control edge and the inflow is in fluid communication with the inflow control edge, and wherein the inflow control edge does not have any or has fewer fine control notches than the outflow control edge and thus works in a largely unrestricted manner, while the outflow control edge is equipped with one or more fine control notches so that with a pulling load at the working tool, the outflow control edge restricts the outflow amount through the outflow of the cylinder.

Mobile work machine

The present invention relates to a switching valve block for a hydraulically actuable work machine that comprises a plurality of valve block inputs for a respective connection to a pressure output of one or more hydraulic fluid pumps, a plurality of valve block outputs for outputting a pressurized hydraulic fluid, and at least one valve that is arranged between valve block inputs and valve block outputs and is adapted to selectively produce a fluid connection between a first valve block input and a first valve block output or between a first valve block input and a second valve block output. The invention is characterized in that the first valve block output furthermore already has a fixed fluid connection to a second valve block input.

Switch valve block for a hydraulically actuatable working machine

The present invention relates to a work machine, in particular a wheeled loader, having an electric motor and having oil cooling that is suitable and intended to cool the electric motor and having a driving axle that has an oil reservoir, wherein a feed line from said oil reservoir to the electric motor and a discharge line from the electric motor to said oil reservoir are present and a pump is present to pump oil from the oil reservoir to the electric motor so that the electric motor is cooled by means of oil from the oil reservoir of the driving axle.

The invention relates to a system for controlling a work machine, in particular a wheel loader, having at least one hand-held control device (), in particular a joystick or steering wheel, at least one restoring device () in the form of one or more spring assemblies, which are connected to the hand-held control device in such a way a restoring force is exerted upon the hand-held control device by the spring assembly when said spring assembly is not in the central position. An adjusting device () which engages with the spring assembly such that an adjustment of the central position of the spring assembly can be carried out, is provided.

Method for controlling a work machine

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 &#x3e;0.5.
