The Intermat is one of the most important exhibitions for the French-speaking market in Europe as well as Africa and took place again this year from 20th to 25th of April in Paris-Nord Villepinte. The international „Who is Who“ of the Heavy Equipment producers were travelling to France to show the latest developments. So did Rockster with the long-term French distributor KoncassToo and presented the innovative Hybrid Impact Crusher R1100DE.

Absolutely unique technology

Rockster's R & D department has developed a worldwide unique drive concept together with European experts of hybrid solutions. The heart of this concept are the so-called power caps, energy buffer with top capacities, which store electrical energy to cover any peak loads. The diesel engine operates nearly constant at optimal speed to drive the generator for the electric motor and does consequently save fuel. The permanent-magnet technology also guarantees lower energy consumption, improved engine and generator performance, and higher power density. With this technology, you can save approximately 16,000 liters of diesel at an annual use of a machine. The energy storage concept would also allow a smaller engine, but because an additional objective was to increase the productivity despite fuel savings, a common CAT 242kW engine is used. This synergy results in a considerable increase in performance and thus significantly more output.

In one of the largest construction companies of France, the Hybrid Crusher is already in use for 1.5 years and does a good job. Operations manager Laurent Perraguin says, "We produce up to 450 tons per hour of recycled demolition material, which is almost 30% more than we had before, the performance is very stable, and the fuel required could be reduced by 30%."
