La mine à l'air essentiellement Komatsu , quelle est la raison pour que Liebherr la choisissre pour ses essais ?
Cette mine a plusieurs avantages, elle utilise des dumpers de la classe 100T, comme le T236, ce qui permet de faire des comparaisons intéressantes. Par ailleurs, elle tourne 24/24, 330 jours par an, avec des variations climatiques importantes (neige, gel...) ce qui permet notamment de reproduire les conditions de la plupart des mines.
Tu as l'explication complète en Anglais Liebherr says the Erzberg Iron Mine in Austria has proven an ideal testing site for the T 236.
“The Erzberg mine gave us a package of testing capabilities that are rare,” says Dr. Burkhard Richthammer, managing director of design and engineering, Liebherr Mining Equipment. For example, the mine has an existing fleet of 100-metric-ton trucks, offering Liebherr a way to directly compare the T 236 with competitive machines.
Located in the Alps, climate conditions at the mine can range from minus 4 degrees Fahrenheit and snow to in-pit temperatures of 104 degrees Fahrenheit. Open 330 days a year, 24 hours a day, Erzberg also offers both uphill and downhill haulage cycles with a constant variation of grade. Richthammer says this site gave Liebherr the ability to demonstrate several features of the T 236.
