Features

The 960E-2K provides the same features as the 960E-2 but uses Komatsu Drive with Siemens liquid cooled insulated Gate Bipolar Transistor (IGBT). In addition, Komatsu Drive provides improve torque capacity, a top speed of 40 mph and Hill Start logic which helps reduce rollback in case the truck has to stop while travelling uphill.
