New Komatsu Dash-8 Off-Highway Trucks: HEAVY HAULING PERFORMANCE, PRODUCTIVITY AND COMFORT

Nov 15, 2018, 09:04 AM by Jeff Richards
Komatsu has introduced new Dash-8 models in four classes of off-highway trucks, adding features that increase productivity while significantly improving fuel efficiency. The remodeled rigid-frame trucks are the HD325-8, HD405-8, HD465-8 and HD605-8, with payload capacities ranging from 40.3 tons to 69.4 tons.
 
Most improvements are featured across all four models, including new Tier 4 Final engines. The HD325-8 and HD405-8 are equipped with a 514-net-hp engine while the two larger trucks are powered by a 724-hp engine. These efficient engines result in fuel savings of 6 percent to 12 percent over the previous models, with savings varying by truck size.
The Komatsu Traction Control System is now standard on all four trucks. The system works without operator input to provide optimum braking in different ground conditions. Komatsu’s traction control doesn’t require differential lock-up, so it doesn’t hurt steering performance.
 
The operator environments have been upgraded to be quieter, and the cabs are outfitted with premium heated and ventilated air-suspension seats to keep operators comfortable and productive for longer periods. Operators will find the new full-color monitor easy to read, even in harsh light. The cab also has a dedicated rearview monitor for improved line of sight.
 
To reduce the time operators spend filling the tank, Komatsu added a fast-fill fuel system.
 
Truck access has been improved, with angled front access stairs replacing the ladder configuration previously used. The stairs, with handrails, are standard on both sides of the machine.
 
“These updated truck models retained their industry-leading steering performance and retarding capacity for maximum production,” noted 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 Dash-8 off-highway trucks are all covered by Komatsu CARE for the first three years or 2,000 hours. Komatsu CARE covers scheduled maintenance, including one complimentary diesel particulate filter exchange, and the program applies whether equipment is purchased, leased or rented.
