Liebherr Mining and VA Erzberg companion to develop 5-kilometre trolley line for mining truck fleet


Since then, the iron ore mine has been testing the diesel-electric truck in Austria. The truck was modified to function with an overhead line related via a present collector with bars on a 500 m lengthy take a look at observe.

That is the best way it really works: The diesel-electric truck is provided with a present collector with bars that join the truck drive system to the overhead energy traces on uphill haulage segments to drive with electrical energy. This revolutionary expertise permits for tracks with small radiuses and even switchbacks. It additionally permits for a wider use of the haul street width apart of the catenary line compared with standard pantograph options. That is of significance when the haul street circumstances will not be optimum resulting from climate circumstances.

Josef Pappenreiter, Technical Director of VA Erzberg says, “There are just a few firms on the planet that use overhead line expertise for his or her vehicles. Nevertheless, we realized in a short time that the present expertise wouldn’t work for us. Our newly developed expertise is totally different from all the pieces beforehand out there in the marketplace when it comes to each the overhead line system and the car expertise itself. This might solely be developed with our cooperative and revolutionary companion Liebherr Mining in Colmar.”

Prolonged observe with new challenges

The brand new prolonged observe for a fleet of six Liebherr T 236 may have a size of 5 km with the higher part at round 1,055 m above the ocean degree. VA Erzberg will probably be observing how the climate circumstances will have an effect on the overhead traces in the course of the winter within the Eisenerz Alps. 

Peter Schimek, venture supervisor on the mine added: “One other problem is all the electrical engineering as all six T 236 may be related to the overhead traces concurrently in a number of locations.” 

When related to the overhead energy traces in trolley mode, the total energy capability of the electrical wheel motors of the T 236 may be translated into pace on grade whereas the diesel engine idles, thus decreasing emissions and gasoline consumption. In the long run, VA Erzberg expects to avoid wasting round three million liters of diesel and 4,200 t of CO₂ per 12 months. Moreover, the emission of nitrogen oxides and high-quality mud will even be decreased. 

Pappenreiter feedback, “With this expertise, we count on a sustainable energy-optimized manufacturing. Round 13 million tons of rock are at present transported within the mine yearly. The associated fee issue for ore manufacturing is correspondingly excessive. Along with the optimistic environmental results, an funding on this new expertise additionally secures the sustainable extraction of the essential uncooked materials iron ore for home metal manufacturing. A complete of round 20 million euros will probably be invested within the venture.”
