The LF-12H is a vehicle which was especially designed for the specific conditions in soft rock mining. The vehicle concept offers a very high level of stability under extreme conditions and offers an excellent visibility and ergonomics due to its low profile machine design and spacious operator's cab. The hydrostatic drive Efficient Drive System (EDS) - in conjunction with an intelligent monitoring system - allows for a significant reduction of power losses during the loading process. Low fuel consumption, brake and tire wear as well as the simple operability are key features of this machine.


  • 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
