Der LF-11H ist ein modernes Fahrzeug für den Bergbau und Tunnelbau unter härtesten Einsatzbedingungen. Die bedeutendste Innovation ist das Efficient Drive System (EDS). EDS ist das Synonym für den für die harten Bedingungen des Untergage-Bergbaus optimierten hydrostatischen Fahrantriebs. Diese Innovation – in Verbindung mit einem intelligenten Überwachungs-System – erlaubt es die Leistungsverluste während des Ladevorganges zu minimieren und setzt neue Maßstäbe in der Produktivität. Niedrigste Betriebskosten werden durch verminderten Kraftstoffverbrauch, Brems- und Reifenverschleiß und eine einfache Bedienbarkeit des Fahrzeuges ermöglicht. Mit einer hohen Vortriebskraft, optimierter Traktion und dem automatischen Belademodus (TIMO) ist ein schnelles Beladen der Schaufel garantiert. Ferner verfügt das Fahrzeug über eine Kapazität von 11 Tonnen bei einer Größe eines 10 Tonnen Fahrladers.
