Komatsu Introduces New Off-Highway Trucks


HD325 8Komatsu America Corp. introduced the new HD325-8 and HD405-8 off-highway trucks. Equipped with an EPA Tier 4 Final certified engine, these latest additions to the rigid frame truck family feature increased horsepower and a new Komatsu Traction Control System (KTCS) to achieve improved productivity. These models have payload capacities of 40.3 U.S. (short)/36.5 metric tons and 44.1 U.S. (short)/40 metric tons, respectively. They replace the HD325-7 and HD405-7 models.

The new trucks’ Komatsu SAA6D140E-7 engines have increased to a net 514 hp (383 kW). Fuel consumption is down for the HD325-8 by as much as 9 percent, and by as much as 6 percent for the HD405-8, compared to predecessors. Also, access is better, with sloped stairs and handrails in front, to replace the previous ladder configuration.

For HD325-8 and HD405-8 machines, KTCS is now standard. KTCS automatically applies independent brake assemblies to achieve optimum traction in varying ground conditions. Because the system operates without the need for differential lock-up, steering performance is not compromised.

Other new standard features for both truck models include a quiet 78 dB(A) cab, 7-in., LCD color monitor, dedicated rearview monitor, fast-fill fuel system, and a premium heated and ventilated operator’s seat with air suspension.

In addition, the tire size for the HD405-8 truck has been increased from 18.00 R33 to 21.00 R33, for extended wear properties.

“The updated truck models retained their industry leading steering performance and retarding capacity for maximum production,” said Rob McMahon, product marketing manager for Komatsu America. “The addition of Komatsu’s latest fuel saving technologies and the all-new cab, lower the cost to maximize production and significantly enhance operator comfort at the same time.”

The HD325-8 and HD405-8 are covered by the Komatsu CARE program for the first three years or 2,000 hours, whichever comes first. Komatsu CARE for these models includes complimentary scheduled engine maintenance and two complimentary Komatsu Diesel Particulate Filter exchanges in the first five years. Komatsu CARE lowers ownership costs, raises resale value and improves equipment uptime and availability. For full program details, refer to the Komatsu CARE reimbursement letter.
