Abstract (en)
[origin: EP2378053A1] The machine (1) has an actuating unit (18) e.g. rotary drilling drive and vibration drilling drive, adjustable with respect to a carrier unit (10) that is formed as an undercarriage, and detectors (51-64) for detecting condition data of the machine. A processor unit (23) determines an adjusting range of the actuating unit based on the data, where the actuating unit is adjustable within the adjusting range with tilt steadiness of the machine. The processor unit determines a position of the actuating unit within the adjusting range, and one of the detectors is formed as a rotary encoder. An independent claim is also included for a method for operating a construction machine.
