  • Patent number: 11485620
    Abstract: An operating method for an industrial truck. The industrial truck includes a hydraulic pump which provides a hydraulic output, an output setpoint value generator which controls the hydraulic output to influence a traveling speed, two drive wheels which respectively comprise a hydraulic drive unit driven via the hydraulic pump, and a hydraulic device. The hydraulic device is switchable between a first switching state, where the hydraulic drive units are supplied with hydraulic outputs which are different, and a second switching state, where the hydraulic drive units are supplied with hydraulic outputs that have a particular ratio with respect to each other. The operating method includes detecting at least one operating parameter of the output setpoint value generator, comparing the at least one operating parameter with a predefined threshold value, and moving the hydraulic device from the first switching state to the second switching state based on the comparison.
