DCRM – Disc Cutter Rotation Monitoring

________________ By localizing damaged or blocked disc cutters, the Herrenknecht system optimizes the maintenance intervals on the . Frequent standstills due to manual inspections of the disc cutters are reduced to a minimum – which makes more efficient and avoids secondary damage to the adjacent disc cutters or to the steel construction of the cutterhead.

The components: Sensors, DCRM Unit and receiver.

Detecting wear on and buckets is already a well-established practice on tunnel boring machines at Herrenknecht AG. Expanding our wear management to disc cutters as a next step makes sense technologically.

The DCRM System assists in early planning and targeted realization of maintenance intervals.
