  • Patent number: 11959469
    Abstract: A method monitors the state of a device having a first drive cylinder for receiving hydraulic fluid and a first drive piston which is movably arranged in the first drive cylinder. The method determines a speed of the first drive piston, establishes a difference between the determined speed of the first drive piston and an expected speed of the first drive piston, and determines a faulty state as a function of the difference established between the determined speed of the first drive piston and the expected speed of the first drive piston.

  • Publication number: 20230265843
    Abstract: A method operates a construction material and/or viscous-material pump having: at least one conveying cylinder, the conveying cylinder being designed to receive and discharge construction material and/or viscous material; and at least one conveying piston, the conveying piston being disposed in the conveying cylinder for movement in order to draw construction material and/or viscous material into the conveying cylinder and to displace drawn-in construction material and/or viscous material out of the conveying cylinder.

  • Publication number: 20220341197
    Abstract: A method is provided for operating a working machine having a device for conveying thick material. A number of target values relating to the operation of the device for conveying thick material can be adjusted by a user. The method includes the following steps: detecting a number of actual values of the device; calculating a target value optimum for a respective target value of the number of adjustable target values based on the number of detected actual values; and outputting a notification for the user, in the event that an adjusted target value of the number of adjustable target values does not correspond to its calculated target value optimum.
