The telescopic truck SK-A30 was specifically designed for low profile mining. Due to the front axle suspension the dump truck has an ideal ground contact, regardless of whether the vehicle is empty or loaded. This is guaranteed even at high speeds with bad ground conditions exceeding 30 km/h. Whether the loading is done by roadheaders or by LHDs with an ejector bucket a secure and fast loading is guaranteed due to its good visibility and maneuverability. By means of hydraulic cylinders and a "push plate" a fast, smooth and low-wear discharge is guaranteed. This avoids the need for extensive expansions at the transfer points. Different cabin designs are offered for different applications.
