Austrian manufacturer Rubble Master has focused since its founding in 1991 on mobile impact crushers for demolition and recycling applications. The product line of the Linz-based company includes compact, tracked mobile crushing plants designed for decentralized material recycling directly on the construction site – an alternative to stationary large-scale plants and traditional jaw crushers.
Product line: RM 60 to RM 120GO! – compact and mobile
Rubble Master offers its impact crushers in a weight class between approximately 10 and 35 tons operating weight. The entry-level model RM 60 processes up to 80 tons of material per hour according to the manufacturer and is suitable for demolition companies with varying job sites. The mid-range series RM 90GO! and RM 100GO! achieve throughput capacities of 250 to 350 tons per hour and are frequently used at recycling yards and larger demolition sites. The top model RM 120GO! reaches up to 400 tons throughput and offers integrated pre- and post-screening – crucial for sorted processing of construction debris, concrete, and asphalt.
All models work on an impact crusher principle: the fed material is accelerated by impact bars and reduced in size through impact. The advantage over a jaw crusher lies in the more cubic grain shape of the end product – relevant for example in recycled concrete or bearing layers in road construction. The machines are standard-equipped with a tracked chassis, can be controlled via remote control, and are ready for transport within minutes – a difference from large, stationary crushing plants that require several days for assembly and disassembly.
Areas of application: demolition, recycling, natural stone
Rubble Master crushers are primarily used in three segments: In demolition, they crush concrete, brick, and masonry directly on the construction site, eliminating transport costs and allowing material to be reused on-site. In recycling, they process construction debris, asphalt, and concrete rubble into recycled aggregates that serve as fill material, frost protection layers, or recycled mineral aggregates. In the natural stone sector, softer rocks such as limestone or slate are processed into gravel or crushed stone – a niche market where compact impact crushers offer cost advantages over large cone crusher plants.
A typical application is decentralized processing of concrete rubble on large urban construction sites: A demolition excavator with hydraulic hammer or pulverizer prepares the concrete sections, which are then reduced to defined grain size in the RM crusher. This significantly reduces truck trips and CO₂ emissions – an argument that is gaining weight especially in emission-regulated city centers.
Market position: niche specialist against large full-range suppliers
Rubble Master positions itself as a specialist for compact, mobile impact crushers – thus differentiating itself from full-range suppliers such as Kleemann (part of Wirtgen Group), Sandvik, or Metso, which in addition to impact crushers also offer jaw crushers, cone crushers, and screening plants. Rubble Master's advantage lies in its focus: the machines are consistently designed for compactness, low transport weights, and ease of operation – factors that are decisive for purchase decisions by small and medium-sized demolition and recycling companies.
In the European market, Rubble Master competes primarily with the Kleemann Mobirex series and the compact impact crushers from Sandvik (QI series). While Kleemann and Sandvik focus on higher throughput and larger machines, Rubble Master concentrates on operating weights under 35 tons – a segment where transport costs, downtime, and flexibility are more decisive than absolute throughput performance. The company does not publish concrete market share figures; industry observers estimate the company's share in the segment of compact mobile impact crushers in Europe at approximately 15 to 20 percent.
Developments: electrification and digitalization
In the past two years, Rubble Master has begun to electrify its product line. First hybrid variants with mains connection and diesel generator are already in operation – particularly on urban construction sites with strict emissions and noise regulations. Fully battery-electric crushers are not yet ready for series production, but the company is testing prototypes with lithium-ion batteries and external charging infrastructure. The challenge lies in the high energy demand of impact crushers: an RM 100GO! requires approximately 150 to 200 kW of drive power – significantly more than a mini excavator or wheel loader.
In the area of digitalization, Rubble Master relies on telematics modules that capture operating hours, throughput quantities, and maintenance intervals. The data is transmitted via mobile connection to a cloud and is available to fleet managers in real-time – a standard that has been established for years at full-range suppliers such as Kleemann or Sandvik. Rubble Master is catching up here, but lags behind the software ecosystems of large competitors. Integration into comprehensive BIM or ERP systems is not currently planned.
Conclusion: specialist for decentralized construction site recycling
Over the past three decades, Rubble Master has carved out a clear niche for itself: compact, mobile impact crushers for demolition and recycling operations that value low transport costs, rapid operational readiness, and ease of operation. The product line covers throughput capacities from 80 to 400 tons per hour and is suitable for both demolition sites and stationary recycling yards.

Compared to full-range suppliers like Kleemann or Sandvik, Rubble Master offers less model variety, but in return provides consistent focus on the requirements of small and medium-sized businesses. Electrification of the product line is underway but lags behind developments in hydraulic excavators or wheel loaders – an issue that will gain importance in light of stricter emission regulations and inner-city zero-emission zones.
