Komatsu America introduced the new HD465-8 and HD605-8 off-highway trucks. Equipped with EPA Tier 4 Final certified engines, these latest additions to the rigid frame truck family combine increased horsepower and come standard with Komatsu Traction Control System (KTCS). KTCS automatically applies independent brake assemblies to achieve optimum traction in varying ground conditions. Because the system operates without the need for differential lockup, steering performance is not compromised.

The new trucks feature a Komatsu SAA6D170E-7 engine that has increased to 724 hp and reduced fuel consumption for the HD465-8 by up to seven percent, and the HD605-8 by up to 12 percent. Machine access is improved with sloped stairs and handrails in front, to replace the previous ladder configuration.

The HD465-8 has a payload capacities of 61 U.S. (short)/55 metric tons, and the payload capacity of the HD605-8 is 69.4 U.S. (short)/63 metric tons.
