The LF-11H is a modern LHD for mining and tunneling with the toughest operating conditions. Its most significant innovation is the Efficient Drive System (EDS). EDS is a synonym for the hydrostatic drive train that is optimized for the tough conditions in underground mining. This innovation - in combination with an intelligent monitoring system - allows minimizing power losses during loading and sets new standards in productivity. Low operating costs are realized by reduced fuel consumption, brake and tire wear as well as by the vehicle’s simple operability. Its extreme tractive effort, optimized tire traction and the semi-automatic loading mode (TIMO) guarantee the fastest and simplest one pass loading and highest bucket fill factors. Furthermore, the vehicle has a capacity of 11 tons with a profile of a 10 ton LHD, thus increasing capacity by 10%.
