Based in Stumm in Zillertal, his ‘RM 90GO!’ is his fourth RM  crusher, with Hauser being particularly enthusiastic about the single deck mesh screen and the pivoting refeeding belt. “The mesh screen is easy to operate and can be transported together with the crusher. We simply unload our RM at the job site and can start crushing. In addition, RM crushers are extremely versatile. You can't do that with other crushers,” says Hauser.  The crusher recycles C&D waste, concrete and asphalt around 500h a year, and granite or limestone for another 500h. Hauser entered the processing business in 2001 when the company purchased an RM 80, with this area now accounting for 20% of the firm's business. 

Excellent service

Günter Prast, managing director of Halbeisen & Prast KG in Dornbirn, tells a similar story. “Service has an extremely high priority at RM, who has had a 24h service hotline since the beginning, something very few suppliers offered 20 years ago. In addition, at Rubble Master someone who knows what they are talking about answers your call; few manufacturers have that either. Every spare part arrives within 24h, which is really sensational. We have a lot of comparisons with products and service provided by other suppliers, which is why we always choose Rubble Master.”

Prast remembers buying his first RM crusher in 1999. That was when he watched RM founder and CEO Gerald Hanisch at a machine demonstration with the RM 60, which later became Prast's first RM crusher. Since then, processing accounts for around 50% of the total volume of material handled. The RM crusher is in operation for around 1,000h annually. This spring, investment was made in the latest technology to be able to operate in the mountains with a Euro V engine even though natural stone processing accounts for only about 20% of material handled. Mostly the new RM 90GO! recycles C&D waste and asphalt in the greater Dornbirn area. Business is doing well and in the past four years around 20 new employees have joined the company, which now employs 45 people.

In action when needed

“I only buy machines that I know are reliable, and everything works in terms of service and spare parts,” says Hermann Dünser from Bizau. As a two person company in the Bregenz Forest region, the reliability of the machines is particularly important to Dünser. Most of his jobs are for private customers, with small commercial companies and municipal operations accounting for around 20% each of business. “If I have to transport 200m³ of rubble and then bring new material to the job site, it costs me too much time. My own crusher makes me more flexible. The Rubble Master crushers are very handy, easy to transport and ready for immediate use. They are also convenient for small business owners like me. If I ever need spare parts, RM always has them in stock and they send me the right part,” says Dünser, who is also extremely enthusiastic about the throughput of RM crushers. “They are awesome. The throughput is unique in this weight class.” 

The company states that was the case twenty years ago, and in 2007 switched to the larger RM 80 model before recently upgrading to a previously owned RM 90GO!. Even though Dünser only uses the RM 90GO! for around 200h a year, it pays off. “My depot is quite small, so it is practical if I can reuse material on site straight away, otherwise I would have to pay landfill fees for construction and demolition waste. The crusher enables me to turn this waste into valuable raw material again. RM impact crushers produce high quality material with well-defined edges. This creates a material cycle,” says Dünser. This illustrates one of the key philosophies that has driven Rubble Master since its inception in 1991: namely sustainable materials management using clever crushers and screens to conserve resources and protect the environment.
