摘要： A work machine includes a moving boom, an ultra-wideband system (UWB) having one UWB tag and a number of UWB anchors, a marking apparatus that can be handled by a user and can be operated by the user, and a control unit. The UWB tag is mounted on the marking apparatus. The control unit is designed so as, when the marking apparatus is operated, to store a position of the UWB tag ascertained by way of the UWB system at the time of the operation and to control the operation of the mobile work machine on the basis of the ascertained position.

摘要： A method controls the movement of a boom, wherein the boom is moved by a plurality of hydraulic drives. Each hydraulic drive is fed with a hydraulic medium, the pressure and/or volume flow of which is adjustable. The method predefines a desired direction of movement and a desired speed of a boom tip; predictively calculates a pressure and/or a volume flow required for each of the hydraulic drives that are required for the desired direction of movement and desired speed; subsequently generates a supply pressure depending on the predictively calculated pressures and/or subsequently generating a supply volume flow as a function of the predictively calculated volume flows; and subsequently feeds the hydraulic drives required for the desired direction of movement and desired speed with the hydraulic medium having a respective feed pressure and/or a respective feed volume flow such that the boom tip moves in the desired direction of movement at the desired speed.

摘要： A method operates a thick-matter pump having a thick-matter delivery system and a hydraulic drive system. The thick-matter delivery system delivers thick matter with a variably settable delivery volumetric flow rate for driving the thick-matter delivery system. The hydraulic drive system has: a hydraulic circuit having a hydraulic fluid, a variably operable first drive pump, and a variably operable second drive pump. The first drive pump is designed for variable operation with at least one variably settable first pump parameter and the second drive pump is designed for variable operation, independent of the first pump parameter, with at least one variably settable second pump parameter for generating a variably settable overall drive volumetric flow rate of the hydraulic fluid in the hydraulic circuit. The method determines an overall-drive-volumetric-flow-rate target value for the overall drive volumetric flow rate, and determines a first parameter target value for the first pump parameter and a second parameter target value for the second pump parameter in a manner dependent on the determined overall-drive-volumetric-flow-rate target value. The first and second parameter target values differ from one another if the determined overall-drive-volumetric-flow-rate target value is in at least one overall-drive-volumetric-flow-rate-target-value range from a set of possible overall-drive-volumetric-flow-rate target values. The method delivers the thick matter with the delivery volumetric flow rate at a delivery-volumetric-flow-rate target value by generating the overall drive volumetric flow rate with the determined overall-drive-volumetric-flow-rate target value by setting the first pump parameter to the determined first parameter target value and the second pump parameter to the determined second parameter target value.
