Features

The HD605-7 is a 70 ton capacity truck that has proven its worth in mines around the world. The HD605-7 has a top loaded speed of 43.5 mph and great climbing power to get out of the pit quickly, dump and cycle back for high production. The oil-cooled wet multi-disc retarder gives the operator great controllability on downhill slopes. A frame designed like Komatsu’s largest mining trucks handles the stress and strains of mining to provide long productive and trouble free life.
