Features

A leader in the 240 ton class mining truck, the 830E-1AC is built on a tradition of excellence dating back to it's introduction as a DC drive truck in 1989. Customers experience the lowest cost per ton operations in the industry while utilizing the 830E-1AC as their prime material hauler. Powered by a Komatsu SDA16V160 engine, the General Electric drive system provides efficient transfer of the power to the ground while demonstrating low fuel consumption and excellent reliability. The dynamic retarding provides the greatest braking efficiency in the industry, utilizing advanced logic including retard speed control. The modern operators cab is fully ROPS/FOPS certified and designed for maximum operator comfort. With a host of options designed for mine specific needs, the 830E-1AC is the only 240 ton class truck you will ever need.
