Rubble Master from Austria has positioned itself in recent years as a specialist for mobile impact crushers in the demolition and recycling business. The compactness of the machines, short setup times, and suitability for changing job sites make the RM series particularly interesting for medium-sized demolition and recycling companies that want to process material directly on site.
Product lines: From compact to medium-heavy
Rubble Master's portfolio is divided into several series, each designed for different throughput volumes and operating weights. The smallest models, such as the RM 60, weigh under ten tons and can be transported with a standard truck – ideal for job sites in cramped urban areas or with frequent location changes. The operating weight remains low, mobility remains high.
In the mid-range segment are models such as the RM 100GO! and RM 120X. These machines achieve throughput performance of 250 to over 350 tons per hour, depending on material type and degree of comminution. They feature crawler undercarriages that work stably even on uneven recycling surfaces, and are often equipped with integrated magnetic separators as well as pre- and post-screening units.
Technical features and practical suitability
All RM crushers are based on the impact crusher principle: material is comminuted through impact stress, which works efficiently especially with soft to medium-hard rocks as well as concrete and bricks. For harder materials such as natural stone, jaw crushers or cone crushers are often the more economical choice – this is where Rubble Master's strength clearly lies in the construction debris and demolition sector.
The machines are designed for quick assembly and disassembly: side conveyors can be unfolded hydraulically, operation is via a central control unit. This reduces downtime and increases utilization – a crucial factor for amortization if you service multiple job sites per month. Maintenance intervals are practice-oriented: wear parts such as impact plates and striking bars can be changed without tools or with minimal effort.
Fields of application: Demolition, earthworks, road construction
Typical applications for RM impact crushers are found in selective deconstruction, where concrete and masonry fractions are processed directly on site into recycling aggregate for road base or as filling material. The machines are also used in road construction, for example for processing milling material or old concrete pavements.
For mobile use on recycling job sites, compact dimensions and low transport weight are key arguments. Those who frequently move between job sites and do not operate a stationary crushing plant benefit from the flexibility – and save expensive haulage to external recycling yards.
Market position and competition
Rubble Master competes with established manufacturers such as Kleemann, Metso, and Sandvik. While major providers often carry broad portfolios with stationary and mobile solutions for all crusher types, Rubble Master focuses on the niche of compact, mobile impact crushers. This focus enables clear product differentiation: short delivery times, specialized service, and construction optimized for frequent site changes.
Rubble Master's market share in the segment of mobile impact crushers under 30 tons operating weight is solid in Central Europe, although exact figures are not published by the manufacturer. In practice, it shows: those who primarily process construction debris and demolition material and rely on mobile solutions will find a coherent concept in the RM series.
Current developments and outlook
In recent years, Rubble Master has increasingly focused on digitalization: telematics solutions enable remote monitoring of operating hours, throughput volumes, and wear conditions. This facilitates usage planning and reduces unplanned downtime. Hybrid drives and electrified auxiliary aggregates are also on the development agenda – however, no series-ready solutions are available yet.
For fleet managers and procurement personnel, this means: if you invest in mobile processing in the coming years, you should keep an eye on the development of electric and hybrid drives – especially if inner-city construction sites or low-emission zones are part of your operational spectrum.
