Wirtgen’s 4200 SM WPI surface miner with integrated measurement system detects wear and tear on cutting tools. WPI stands for Wirtgen pick inspection — and essentially consists of eight very quickly measuring sensors integrated in the cutting roller housing. These sensors are used to measure the wear of the cutter. WPI can take measurements in less than one minute and this can be carried out easily during truck changeover so that downtimes can be avoid- The use of WPI provides the machine operator with a ed.
