Enhanced safety and maximum convenience
The RM Group once again sets new standards in user-friendliness with RM NEXT. As the first NEXT philosophy crusher, the RM 120X combines maximum safety with maximum performance and flexibility. Using RM Operations Assist and RM GO! SMART, the crusher interacts with the machine operator who is able to see the status of the machine from the loader cab. The Performance Indicator also enables maximum efficiency in processing without leaving the cab.

Maximum throughput capacity and maximum flexibility
The best ratio of weight to throughput capacity, combined with equipment perfectly matched to each application, guarantees maximum flexibility. Depending on the application, the RM crusher can be equipped with the optimum equipment options and drive technology. In addition, it is more efficient during operation thanks to a larger diesel tank.
