The LF-5 is a powerful LHD for narrow workings in hard rock mining and in tunneling. Due to its excellent power to weight ratio the LF-5 performs well even in high altitudes. With its canopy in the front an excellent visibility is guaranteed, in particular during the loading process. The LF-5 can be optimally combined with the MK-A15.
