Abstract

An apparatus for determining the effective operating life, or working life, of a machine for moving loads, in particular in the form of a crane, comprises means (Cnm) for counting the number of cycles (Nnm) that have occurred for corresponding oscillation intervals (Pnm) of the signal detected. The apparatus also comprises means that use this count for calculating a data item defining the effective operating life in relation to the operating life limit defined for the machine and means (25, 25', 26) for displaying the effective working life.
