RUBBLE MASTER Compact Recyclers – Intelligence inside

The success of a development is judged in retrospect – by the customers themselves. It is achievable by addressing existing requirements early on and by using state-of-the-art technology. The inventors of Compact Recycling have been taking this approach since 1993 and always rely on maximising efficiency while minimising running costs – much to the benefit of their customers. With 700 satisfied users around the globe the RUBBLE MASTER machine concept with its intelligent control technology has proven its worth hundreds of times – and the success has long since surpassed traditional thinking.

The diesel/electric power concept has become established as the industry standard in serious processing technology. This is why nobody today would describe this concept as unreliable. It has long been clear that the best hardware – also in the case of construction machinery – is not much use unless you can take full advantage of the performance potential of the machine thanks to high-quality software. This is the only way to achieve perfect solutions that give the customer maximum benefits. The RUBBLE MASTER developers have taken development concepts proven over the years for large processing machinery and applied them with perfection to compact, mobile crushers.
The often quoted RUBBLE MASTER Best Solution Principle ensures users a technically proven series standard, as is to be expected from a quality supplier. Additionally it guarantees reliability and cost-efficiency. The developers have always acknowledged that the customer's wish of having compact machines to handle a wide range of small and large jobs with varying materials and high expectations when it comes to the final grain has to be satisfied – using one crusher which guarantees maximum flexibility, is mobile, has surprisingly high throughput despite the compact dimensions and, thanks to this compactness, can be transported easily using standard equipment and without any special permits.
RUBBLE MASTER also stands out in manufacturing terms, with the highest industry standard both in the selection of high-quality components and through suppliers of international repute. Most of them have a long-standing business partnership with the company and are closely involved in development work. Great importance is also attached to the service quality of the suppliers, especially with regard to the availability of parts and fast service when required. It is for this purpose that supplier workshops are held on a regular basis to coordinate requirements and consolidate the working relationship.

Up to 25 percent more drive power with lower diesel consumption

Customers benefit from an ingenious machine concept for maximum performance with low consumption and future-oriented environmental acceptability. This is possible due to an optimised crusher drive concept with diesel engines certified as low-emission. The perfectly matched Deutz engine stands out through high efficiency, saving at least 10 percent in the process – a decisive factor, bearing in mind the ever increasing price of crude oil. Vibro channel and discharge belts are operated electrically using an integrated three-phase generator which also powers all the external equipment, even on remote job sites where no electricity is available.

Fully remote-control functions guarantee safe crushing. No personnel are needed at the machine throughout the entire crushing process! RUBBLE MASTER crushers really do require only the one operator: it even takes less than 10 minutes to unload the machine. The operator driving the loader is able to control the crusher functions and movements from the loader cab – incidentally the safest place to observe the crusher in operation. All operational crusher functions are controlled using the radio control unit: automation, conveyor speed, crusher inlet and Release System and, of course, the crawler gear. While the models RM60 and RM80 prevent clutch wear with switching taking place only when the crusher is not in operation, a new, virtually loss-free concept was developed for the RM70, which has a maintenance interval which is equal to the service life of the crusher.

The benefits of the RUBBLE MASTER machine concept are convincing even for stalwart supporters of hydraulics in the USA. Alan Huber, a construction machinery dealer in California with years of experience and a fleet of 150 diggers, has been a fan of the diesel/electric concept for two and a half years: "We Americans have grown up with hydraulics. But we value economic solutions. So why should I keep on spending money on diesel and hydraulic oil unnecessarily when there is a much more efficient power system? With the RUBBLE MASTER RM80 I didn't have a single drive or control technology failure in 1,450 operating hours. And for any other problems there are always the guys in after-sales with their expert knowledge and the reliable troubleshooting tree who can solve just about everything immediately on the phone. That's what I call profitable construction machinery!"

High-tech for more productivity and the edge over competitors

Maximum throughput continuity is a significant purchasing criterion for RUBBLE MASTER Compact Recyclers. After all, it is at the end of the day – or when settling accounts on the job site – and not by looking at performance peaks when you can judge the actual performance. This begins with the optimum feeding cycle and conveying in line with crusher load.

This requires integrated intelligence, as in the case of the RM70 with its second generation automatic conveying system. The decision to use the programmable controller (PLC) was taken back in 2001 in the development of the RM80. Whereas the RM80 features 4 preselectable steps according to material and feed type, the material flow on the RM70 is automatically regulated so the crusher is operated at full capacity, avoiding overload. The conveyor speed is adjusted to handle the specific task. In addition to this the rotor speed is adjustable so it is just right for the job in question. The result is defined, exceptionally homogenous final grain in the desired screen line analysis – a high-quality raw material which can be used to make profits. The transfer from vibro channel to crusher, impact plate kinematics and the rotor intake performance are likewise optimised. The initial crushing benefits from high-quality crusher tools, the shape and material of which are constantly being further developed for even longer service life. The unique RUBBLE MASTER Release System, which removes any blockages within seconds and works via remote control, makes sure the material is processed continuously. The magnetic separator reliably removes any ferrous items from the crushing material.

No need to be concerned about running costs

Because the maximum availability and productivity of the RUBBLE MASTER machines guarantee cost-efficient operation. It is for precisely this reason that RUBBLE MASTER Compact Recyclers always have been and always will be made for the benefit of the customer. They fully comply with the requirements of a modern building company that works cost-efficiently and is either just about to start out in the recycling business, is going to add recycling to his range or is already a professional recycler who demands proven, quality products. But that's not enough for the Best Solution Principle: RUBBLE MASTER users value the straightforward operation and no-nonsense maintenance – particularly the easy access from ground level, for fast and safe service work and maximum machine availability.

RUBBLE MASTER's dynamic duo RM80/OS80 is a highlight in cost-efficiency: it is used to produce up to 120 t/h of high-grade final grain from a variety of feed materials with just one operator and in one pass. Low investment costs, no transport or disposal costs and high value retention optimise the users' bottom line. "Great to be in the business!", as the RUBBLE MASTER advertisement says. Customers appreciate that RUBBLE MASTER not only offer machines, they also give you solutions for success: smaller companies in particular that secure their company's future with recycling, classic medium-sized businesses that have their costs under control and an increasing number of large concerns, concentrating on quality.

RUBBLE MASTER users worldwide also value the reliability in further development: many are already awaiting the next innovation so they can upgrade or expand their machine range – the manufacturer's promises of rapid amortisation and economic success have been kept. This is music to the ears of the developers. Developers who take their job very seriously, just as all the requirements of their customers. This is what saw the first RUBBLE MASTER emerge from virtually nowhere back in 1993 – the result of the concrete demand of a circle of customers who had not been provided with the appropriate machines in the past. Ever since the birth of mobile Compact Recycling, RUBBLE MASTER has always succeeded in satisfying the growing circle of customers and has established itself as an strong, unfailing brand in a niche market.

The reliability of an experienced service team in the background

Besides outstanding machine technology, with which RUBBLE MASTER have been setting standards in construction machinery for over 12 years now, unrivalled service quality and after – sales support are a top-level guiding principle. Even the best of machines are only as good in practice as service in an emergency. This is why world-class customer care and professional after-sales competence – whether it's the telephone hotline or experienced local service partners, first-rate documentation and extensive training – guarantee that RUBBLE MASTER machines operate smoothly and profitably.

A dedicated team at the manufacturer's headquarters is right in claiming that they know any malfunction that could occur and have the remedy for it. Malfunction statistics have been kept over the years and have been taken into account as a preventative measure in every further development. A malfunction search tree makes it easier and quicker to find the cause of the malfunction and normally makes it possible to remedy it within a very short time. The control technology in particular makes troubleshooting easier. Plus all the electrical components are standardised parts that are easily identified at the machine and available at short notice wherever you are.

Top priority is also given to the rapid supply of wear and spare parts with the original RUBBLE MASTER quality. This is managed worldwide via the central logistics office in Linz, supported by regional competence centres. Clear evidence of RUBBLE MASTER's commitment to customer orientation could be seen at the end of 2004 as the company invested in a large-scale, modern Service Centre. This is what sets RUBBLE MASTER aside from its competitors – it stands out through the competence of a manufacturer's service, especially as manufacturing expertise is maintained with in-house final assembly. Whether as part of the regular machine maintenance or as a service before the next season begins: here, all machines are checked free of charge by the service experts. The customer receives an individual quotation specifying the required service work and also inexpensive updates to increase productivity and retain the value of the machines long-term.

Besides a fast and cost-efficient job, the accent here too is on advising the customer in respect of improving performance and reducing costs. As part of the Active Wear Cost Management programme RUBBLE MASTER customers are advised by the Service Centre on how to use original RUBBLE MASTER quality crushing tools to reduce wear and costs, plus intelligent solutions that make work easier – such as hammer lifting devices and much more.

Environmentally acceptable recycling with RUBBLE MASTER

A further criterion which is becoming increasingly important on an international scale is the environmental impact of a crusher. Large-scale demolition sites are now part of normal day-to-day business in the construction industry. The increasing amount of leftover building materials requires an efficient system for recycling directly on-site to avoid unnecessary transport runs. Conditions at inner-city job sites in particular are scarcely comparable with those at remote gravel pits or in stone quarries, where noise pollution is not a major concern. Faced with advancing mechanisation and heavier traffic, legislators are under constant pressure to bring emissions under control and stipulate ever decreasing emission limits for construction machinery.

This is why, since 2003, RUBBLE MASTER has been devoted to setting standards in environmentally acceptable recycling. Here too, high efficiency and economy are of the essence – not forgetting machines that are already extremely environmentally friendly as they can be used on the job site, saving transport as a result. These principles come into effect already in the development stage: the environmentally-friendly crusher drive system uses low-emission, certified diesel engines. The power supply to the vibro channel and discharge belts is electrical via an integrated three-phase generator. Hydraulics are used only for secondary functions and are switched on only when the crusher moves. The small tank volume has a positive effect on maintenance costs and, in the event of a malfunction, environmental impact is kept low.

Thanks to its low noise levels the first RUBBLE MASTER RM60 was also ideal for use in residential areas; the RUBBLE MASTER ENVIRO concept for minimum consumption and extremely low emissions was developed to comply with increasingly stringent guidelines. The consistent study of noise protection was reflected in very favourable noise levels in various noise analysis tests. This was achieved by implementing a wide range of measures. From the outside you can see the special cover over the crusher to suppress crushing noise. Selected materials have also been fitted to the crusher inlet to reduce noise. Noise reduction is enhanced even further by an optimised exhaust system. Inside the machine, a finely tuned low-emission diesel engine shows how important environmental impact is for RUBBLE MASTER machines. An intelligent dust suppression system is fitted at several points to cut down on airborne particles – both in the crusher and on the discharge conveyor belt.

This forward-thinking concept was featured and perfected in the development and design of the RM70. By eliminating noise at the source, noise suppression is extremely impressive – with the integrated frame construction and drive unit. The large expansion chambers inside the crusher can be sprayed efficiently with water to keep dust to a minimum.
The RM70 inner-city crusher stands out from the rest because this whispering machine works even where space is limited and residents have to be taken into consideration. RUBBLE MASTER also supports its users in organising an optimum and environmentally safe recycling site.

 

Quality and dynamism are the hallmarks of the successful development of the RUBBLE MASTER brand, together with the organisation that goes into it – the mastermind behind a growing network with the core competences of engineering, marketing and service. A mechanical engineering company in particular has to rely on the quality standard and dedication of its partners in sales, service and manufacturing. Only this way can a product turn into a profit-making instrument for the customer – from the brainwave to an unconventional engineering solution. The new research and development centre ensures the continued innovation potential of this powerful international brand through shorter development times. Extensive test series before the market launch also ensure the full security of technology you can rely on.
