Der LF-12H ist ein speziell an die besonderen Bedingungen des Weichgesteinsbergbaus angepasstes Fahrzeug. Das Fahrzeugkonzept bietet eine sehr hohe Standsicherheit unter extremen Bedingungen und verfügt aufgrund seines flachen Aufbaus und geräumigen Fahrerstands über eine überragende Übersichtlichkeit und Ergonomie. Der hydrostatische Antrieb Efficient Drive System (EDS) – in Verbindung mit einem intelligenten Überwachungs-System – ermöglicht eine erhebliche Reduktion der Leistungsverluste während des Ladevorganges. Niedriger Kraftstoffverbrauch, Brems- und Reifenverschleiß und eine einfache Bedienbarkeit des Fahrzeuges runden dieses Modell ab.

EIGENSCHAFTEN

  • Efficient Drive System (EDS) for highest productivity and reduced maintenance costs
  • Semi-automatic loading mode (TIMO) simplifies and speeds up loading
  • Intuitive two pedal control for faster cycle times
  • Hydraulic brake hybrid (HBH) for recuperation of brake energy
  • Advanced controls and condition monitoring systems
  • Extremely robust GHH frame and system design resulting in lowest operating cost
  • Load sensing hydraulics for lower oil temperatures and higher energy efficiency
