Reliability modelling for maintenance scheduling of mobile mining equipment

Raymond Alfred Summit, David Halomoan


It was observed that in a particular open-pit mine, failure of the front and rear suspensions of a particular model of dump truck frequently occurs before the scheduled replacement of the parts. The Weibull distribution is used to model the time to failure of these components. Maximum likelihood estimators of the parameters are obtained and used to find a more appropriate replacement time.
