The LF-3 is the smallest LHD in the GHH Fahrzeuge portfolio and is designed for extremely narrow veins. The machine is worldwide proven in hard rock mines as well as in tunneling operations. Despite the small dimensions, the LF-3 provides an ergonomically designed cabin and a good visibility. The machine is characterized by an extremely simple and robust structure and is particularly suitable for underground applications in high altitudes.
