With the launch of WPI, Wirtgen is introducing a new system which measures the wear of surface miner cutting tools.
WPI – Wirtgen Pick Inspection – principally comprises eight very rapid measuring sensors which are integrated in the cutting drum compartment of the surface miner. These sensors measure the degree of wear of the picks. Taking just one minute to complete, the measuring process can easily be carried out while changing trucks, thus avoiding downtimes.
App for service teams slashes tool-changing times
WPI is very simple to operate: the entire measurement proceeds fully automatically at the push of a button. A separate mobile end device, which forms part of the cutting drum, marks the worn pick in colour on its display. The result of the measurement is displayed clearly, making life very much easier for machine operators and service technicians, who can plan the necessary service intervals optimally – both in terms of personnel requirements and spare parts stocks – based on the wear information for individual machines. The system also ensures that the cutting tools can be used for the maximum length of time.
These optimized service and production processes will offer vast material benefits to mining companies which use entire fleets of surface miners in 24/7 operation.
