RUBBLE MASTER Welcome! to our world

Welcome to the world of the RM Group, the leading manufacturer of mobile crushers and screens. Both our competence centres RM Dungannon, an expert in screens, and RM Headquarters in Linz, a specialist in crushers, keep on raising the bar with their trailblazing technologies. Thanks to their cost effectiveness and consideration towards the environment, RUBBLE MASTER mobile machines enjoy a high level of acceptance in the recycling and processing of natural stone.

One of the key focal points of the RM Group is on research and development. Mobile crushers and screens that offer the highest level of customer benefits as a result of their innovative solutions, have top priority at RUBBLE MASTER. RM innovations have made our mobile and extremely powerful machines the market leader in our segment.


As the world market leader in mobile crushing and screening as well as recycling in the compact class, RM offers excellent opportunities in various areas for your career in the mechanical engineering industry. The visionary Gerald Hanisch founded RUBBLE MASTER in 1991. Thanks to the excellent economic development, we are constantly expanding our locations and looking for new employees.


RM sets standards in compact crushing and screening. In 2008, RUBBLE MASTER revolutionised the crusher market with the intuitive RM GO! principle. We have since grown to become the RM Group, and are now developing the product philosophy further with the RM GO! principle as an integral part of the RM NEXT philosophy. With RM NEXT, the RM Group goes one step further by implementing a machine2machine communication system connecting crushers and screens.
