Der LF-14HE mit dem bewährten Antrieb EDS bietet durch seine einzigartige Kombination aus Elektroantrieb und stufenlosem hydrostatischen Getriebe eine hohe Effizienz und Ergonomie. Das Fahrzeug ist somit für die härtesten Einsatzbedingungen des Weichgesteins- und Erz-Bergbaus unter Tage optimiert. Das Fahrzeug erfüllt höchste Ansprüche an Ergonomie und Wartungsfreundlichkeit. Die Maschine zeichnet sich durch einen robusten Aufbau aus und ermöglicht somit geringste Betriebskosten bei höchster Förderleistung. Der LF-14HE ist mit einem aktiven Trommelantrieb ausgestattet, der eine geordnete Wicklung garantiert, wodurch lange Standzeiten des Kabels, aufgrund geringerer Zugkräfte, erreicht werden.
