Anyone who wants to process material on-site at a demolition site or recycling yard is increasingly relying on mobile crushing systems. Austrian manufacturer Rubble Master has made a name for itself in this segment with compact, track-driven impact crushers. But which models are the right choice for which application – and what should you as an operator pay attention to when purchasing and operating them?

Product line: Compact impact crushers for mobile use

Rubble Master focuses on mobile crushing systems with impact crusher technology, specifically designed for recycling construction waste, concrete and asphalt. Unlike traditional jaw crushers, impact crushers operate at high speeds and are particularly suitable for processing soft to medium-hard materials. The systems are completely mounted on track chassis and can be assembled and disassembled without crane support – a decisive advantage on changing construction sites.

The product line includes models in various performance classes, with the RM 60, RM 90GO! and RM 100GO! among the best-selling machines. They all share the all-in-one solution concept: crusher, pre-screening unit, side discharge conveyor and magnetic separator are already integrated from the factory. This reduces not only the number of machines needed on the construction site, but also the logistics effort when transporting between different locations.

Top models at a glance: From compact class to high-performance crusher

RM 60: Entry model for smaller recycling volumes

With an operating weight of around 14 tons, the RM 60 is one of the most compact models in the portfolio. The throughput is up to 80 tons per hour – ideal for smaller demolition contractors or municipal construction yards that want to process manageable amounts of material on-site. The system can be transported on a standard lowboy trailer without requiring special permits. For you as an operator, this means: high flexibility at low transport costs.

RM 90GO!: Versatility for changing requirements

The RM 90GO! is the workhorse of the product line and is frequently used by medium-sized construction companies that operate both concrete and asphalt recycling. With a throughput of up to 220 tons per hour, the model is in the mid-performance segment. Particularly noteworthy is the integrated pre-screening system, which separates fine material before the crushing process and thus reduces wear on the impact bars. This extends maintenance intervals and noticeably reduces operating costs.

RM 100GO!: High performance for large recycling projects

If you regularly process large amounts of material at stationary recycling yards or for large-scale demolitions, you can hardly avoid the RM 100GO!. The system achieves up to 250 tons per hour and has a particularly large feed hopper. This also allows the use of wheel loaders with larger buckets, which speeds up feeding. The integrated diesel direct drive technology provides comparatively low fuel consumption – an important factor in multi-shift operation and rising diesel prices.

Market position: How does Rubble Master compete?

In the segment of mobile impact crushers, Rubble Master competes primarily with established manufacturers such as Kleemann, Metso and Sandvik. While these providers often focus on larger, more powerful systems for mining and quarry operations, Rubble Master has specifically specialized in compact, easy-to-transport machines for construction waste recycling. This focus pays off: In Europe, the RM models are particularly widespread among smaller and medium-sized companies that value rapid mobility and uncomplicated operation.

Another distinguishing feature is the service network: Rubble Master relies on a dense dealer network with its own technicians who specialize in impact crusher technology. This reduces downtime in case of breakdowns – a critical factor when you need to complete your demolition and recycling projects on schedule.

Current developments: Electrification and digitalization

Like many manufacturers, Rubble Master is working on electrifying its product range. First prototypes with hybrid or fully electric motors have already been shown at trade fairs, but series production is still pending. At the same time, the manufacturer is increasingly equipping its systems with telematics systems that digitally record operating hours, fuel consumption and maintenance intervals. For fleet managers, this means: better planning capability and more precise cost calculation.

Additionally, Rubble Master has recently invested more heavily in developing wear-optimized impact bars and screen covers. The goal is to further increase the service life between maintenance intervals – a direct contribution to reducing the total cost of ownership (TCO).

What you should pay attention to when purchasing

If you are considering purchasing a mobile impact crusher system from Rubble Master or another manufacturer, you should check the following points:

  • Throughput capacity: Do not choose the model too tightly – a buffer of 20 to 30 percent above your average requirements prevents bottlenecks at peak loads.
  • Transport weight and dimensions: Make sure that the system can be transported on your existing fleet without requiring special permits.
  • Material spectrum: Not every impact crusher processes asphalt and concrete equally efficiently. Clarify in advance which materials you will mainly be processing.
  • Service and spare parts: A dense dealer network and fast spare parts supply are business-critical for mobile systems – every day of downtime costs revenue.

For operators who already have experience with mobile crushers on recycling construction sites, Rubble Master offers a solid, field-proven solution. However, if you are investing in mobile processing technology for the first time, you should also look at competing models from Kleemann or Metso and compare the offers in terms of throughput, maintenance requirements and payback period.
