Permanent condition monitoring of wheeled excavator in Chilean copper mine – Early defect detection essential for maintenance scheduling
HERZOGENRATH, September 16, 2004 – FAG Industrial Services (F’IS) is using a Condition Monitoring assignment in the mining sector to further expand its activities in South America. A wheeled excavator facility manufactured by FAM Magdeburger Foerderanlagen und Baumaschinen GmbH has been equipped with several of FAG’s DTECT X1 systems for permanent Condition Monitoring and is operated in copper surface mining in Chile. This far away from civilization – in the desert, so-to-speak – early defect detection is of particular significance, not least due to the long transport distances for spare parts. Unplanned downtimes are something copper mine operators cannot afford because logistics planning and the procurement of spare parts take up a lot of time and cause exorbitant costs.
The modern DTECTX1 series developed by the condition monitoring experts from Herzogenrath consistently monitors wheel excavator components such as excavator bearings and drives that are exposed to particularly high loads under harsh conditions, including dust and extreme temperature changes. These systems are very efficient and cost-effective vibration devices that work with permanent frequency selection monitoring. The vibration data acquired from the sensors installed are transmitted via radio to the control station. An alarm signal is emitted for any deviation from individually defined limit counts or alarm limits. Simultaneously, the monitoring system provides the operator with an objective decision support for maintenance scheduling. These systems also allow remote monitoring through fixed network, radio or satellite modems, including a detailed depth analysis by F’IS service center experts.
When using frequency and envelope spectra to determine the condition of equipment, the decisive factor is that this allows both the evaluation of the cause for an increased vibration level and the localization of the damaged component. This method also enables operators to determine the type of damage for rolling bearings (outer ring or inner ring, rolling element). This in turn provides important information about reaction times because the rate at which this type of damage develops varies. For maintenance scheduling, in the desert and elsewhere, this means that early damage detection allows operators to request spare parts and service technicians in time and to complete retrofitting as part of regularly scheduled maintenance intervals.
FAG Industrial Services GmbH (F’IS) Since the beginning of 2001, FAG Kugelfischer AG, a member of the Schaeffler Group, has been focusing its service business in FAG Industrial Services GmbH (F’IS), headquartered at Herzogenrath near Aachen. As an independent company, F’IS offers its maintenance services and service products on a manufacturer-neutral basis, so helping customers to save maintenance costs, optimize machine availability and avoid unexpected machine downtime.
