SLEWING DEVICE MONITORING APPARATUS AND METHOD

摘要

A method of monitoring performance of a slewing device and in particular predicting an operational life-time of the slewing device based on real-time tilting moments. The method comprises measuring real-time force related parameters at a superstructure mounted upon a support structure via a slewing device. The operational life-time of the bearing is accordingly adjusted and determined based on real-time measurements as the machine is operative.
