Josef Hamminger’s core business is reclaimed building materials. He demolishes around 200 old farm buildings a year and also processes the C&D waste. For more flexibility, he has now purchased his own RM crusher. What crushing has to do with feelings and beer crates, you can find out here.

Josef Hamminger is on the move throughout Austria and Bavaria with his RM 70GO! 2.0. Based in the Innviertel region of Austria, he demolishes farm buildings and old structures on narrow inner city sites as well as in the mountains. As carefully and lovingly as he handles the reclaimed wood, he also puts a lot of feeling into the way he treats his machines: “We look after our equipment!” When preparing material for crushing, Hamminger cites the “beer crate” as the measure of all things: “With a crusher, it is very important to prepare the raw material well. The feed material must not be too big, otherwise you will block the system and everything will stop. If you make sure that chunks of concrete are no larger than a beer crate, then you can keep feeding the crusher at a high throughput rate. We sometimes even feed material in with two excavators because that’s the throughput the crusher manages!” His team sort out the reclaimed wood and metal. C&D waste and concrete is broken up in advance using an excavator and chisel and then piled into a heap. When the crusher arrives on site, it can start crushing right away. “If you do that, you achieve a high throughput and much less wear. The hammers last seven times as long!”, says Hamminger in describing his experience. All this sounds like years of experience, but the business owner has only been using the RM 70GO! 2.0 for two years.


Owning a crusher means more flexibility and sticking to schedules

Before Hamminger purchased his own crusher, he experimented with excavator crushing jaws and rented mobile crushers. “My customers want a complete package. It’s not enough for me to just to collect the old wood. They want demolition and recycling from a single source. Many can reuse the recycled material directly on site. In the past, I often had to make a lot of phone calls to then have a crusher available at the right time. When you have to rely on another company, there is always the possibility of delays and waiting times. That’s why I bought the RM 70GO! 2.0 in 2020. I have a much quieter life now I have my own crusher and can plan better. I know when my job sites will be completed,” says Josef Hamminger, who likes to be able to keep to deadlines. That is how he can reliably offer his customers a complete package for the demolition and processing of C&D waste.


Optimising costs with your own crusher

Having his own crusher not only makes Hamminger flexible and saves stress, it also reduces his costs. “We used to have up to pay up to €60,000 a year for rented crushers,” the company owner explains. He has calculated the purchase costs and the operation of his RM 70GO! 2.0 at 400 hours per year over five years. “We used to rent crushers for 350 to 400 hours a year. Now we crush 400 to 500 hours a year. That’s where we have optimised our running costs with our own crusher,” says Hamminger.


The RM 70GO! 2.0 hardly damages the ground

When you rent a crusher, you never really know how big and heavy the machines that are available will be. “Sometimes we have job sites where only 40-50 m³ need to be crushed. This is only possible with a crusher as flexible as my RM 70GO! 2.0. It is quickly loaded onto the low-loader and soon ready for action. At just under 20 tonnes, it also hardly causes any damage to the ground, plus I can drive it up mountains and work in inner cities. It operates very quietly and manages a super throughput despite its compact size,” says Hamminger.

Josef Hamminger founded his company in Gurten in the Innviertel region of Austria in 1995, originally as a building materials firm. Its main business is now recycling and selling reclaimed building materials. The resourceful entrepreneur has registered seven different businesses and sells the reclaimed wood all over Europe. He currently employs around 30 people. More at:

Natural rock

Crushing at a high output and low wear, and that in every possible and impossible location, is not an issue for RM crushers. They manage to generate the highest quality value grain from natural stone on site. Depending on the desired combination of machinery. The end result is always cubic aggregate.

Abrasive rock

Quartz gravel, granite and riverbed gravel are not easy to process because high levels of quartz cause high wear. However, RM crushers are designed for such materials: thanks to their compact size they can achieve high throughputs even in tight spaces, producing valuable aggregate directly on site at all times.

Schrefler relies on RM hybrid crusher

Demolition work and mobile recycling have been part of Manfred Schrefler’s range of services since 2016; previously he was known primarily for transport and earthwork. In terms of machinery, the Upper Austrian relies on top quality and always has the very latest technology.

Basalt preparation

Crushed basalt is used for a variety of purposes. Most often, it is crushed to be used as an aggregate in construction projects.

Increase in orders with cuboid final aggregate

In Mexico the RM 100GO! replaces a jaw and cone crusher combination. Basalt with a diameter of up to 500 mm is crushed into different sizes of cuboid final aggregate, which is then reused for asphalt production. Final aggregate grades between 0-19 and 0 25 mm are processed to a high standard without any problems.

RM 70GO! 2.0 crushes hard river basalt

The first mobile RM crusher in Gorontalo, Indonesia, has been in operation since spring 2017. The new RM 70GO! 2.0 replaces several machines at once: instead of using the jaw crusher combined with a cone crusher, this mobile crusher unit processes extremely hard river basalt in a single pass.
