It all began in 1991 with an idea from Gerald Hanisch, the founder and owner of RUBBLE MASTER HMH GmbH. The goal was to give as many entrepreneurs as possible the chance to use mobile rubble recycling for value enhancement. It was with this innovative concept that RM created a market: on-site recycling!

RUBBLE MASTER has concentrated on its core competences since the beginning: development, marketing and service for mobile crushers in the compact class. With the acquisition of the Northern Irish screen manufacturer Maximus and the rebranding to RM Group, another focus was added – the production of our own mobile screening plants.

It all began in 1991 in a small office in Linz and a hired unit where we began to develop and sell compact processing machines for a wide variety of applications. Innovative products and professional services form the basis of RM’s success and it has since developed into the world leader in mobile crushers in the compact class.

Successful growth led to the building of RM headquarters in Linz-Pichling in 2001. Our corporate culture is reflected in the extension built in 2009 where offices and production moved closer to each other. Open-mindedness and transparency are values that reflect RM principles and foster true partnerships in business. These principles have also been put into practice at RM Dungannon, the centre of excellence for screens, since 2018.
