Abstract (en)

[origin: WO2012016666A1] A method for continuously and simultaneously monitoring a plurality of operatively connected mechanical and/or hydraulic drive components provided in at least one drive train in a large hydraulic excavator by virtue of a vibration sensor being positioned in the region of just a single one of the operatively connected drive components, said vibration sensor being connected by means of a line to an evaluation unit which contains prescribable conspicuousness patterns for all the operatively connected drive components, and the collective measurement signal from all the operatively connected drive components being aligned in conditioned form, as an input frequency, with a limit value - associated with the respective individual drive component - from the conspicuousness pattern.
