What is the most popular Komatsu dump truck model?
For mining, the Komatsu HD785 (currently the HD785-8) is widely considered the brand's flagship rigid hauler, with a rated payload of around 101 U.S. tons and a 1,140 net-horsepower SAA12V140E-7 engine. In the articulated category, the HM400-5 (44-ton class) consistently ranks among the top three best-selling ADTs in North America, alongside the smaller HM300-5.
What is the biggest Komatsu dump truck ever made?
The Komatsu 980E-5 is currently the largest rigid dump truck Komatsu produces. Introduced in 2019, it has a nominal payload of around 363 tons (327 metric tons) and is powered by an 18-cylinder SSDA18V170 engine generating about 3,500 horsepower. It's used primarily in large-scale mining operations in North America and Australia.
What's the difference between Komatsu's "HD" and "HM" series?
HD models (HD465, HD605, HD785, HD1500, etc.) are rigid-frame off-highway trucks designed for mines and quarries with prepared haul roads. HM models (HM300, HM400) are articulated dump trucks (ADTs) with a pivot joint between the cab and bed, built for soft, muddy, or uneven terrain typical on construction sites.
How much payload can a Komatsu HD785 carry?
The HD785-8, the latest generation, has a rated payload of approximately 101.6 U.S. tons (about 92 metric tons) and a 78.5-cubic-yard V-shape dump body. Earlier generations like the HD785-7 carry around 91 tons. It's a workhorse for high-production mining, quarry, and aggregate applications.
Are Komatsu dump trucks diesel or electric?
Komatsu offers both. Mid-size haulers like the HD465, HD605, and HD785 use mechanical (diesel) drive systems. Ultra-class trucks such as the 730E, 830E, 930E-5, 960E, and 980E-5 use diesel-electric drive, where a diesel engine powers an alternator that drives AC traction motors at the rear wheels — more efficient and easier to maintain at huge tonnages.
How much does a Komatsu dump truck cost?
Prices vary widely by class. Articulated models like the HM300/HM400 typically range from around $500,000 to $900,000 new, mid-size rigid trucks like the HD465/HD605 fall roughly between $1 million and $1.5 million, and ultra-class electric-drive trucks like the 930E-5 or 980E-5 can exceed $4–5 million. Used units start much lower depending on hours and condition.
Where are Komatsu dump trucks manufactured?
Komatsu, founded in Japan in 1921, manufactures dump trucks at several global plants. Articulated models like the HM400-5 are now built in Chattanooga, Tennessee (production began there in 2023) as well as at the Ibaraki, Japan, plant. Ultra-class electric-drive trucks such as the 930E and 960E are assembled in Peoria, Illinois, USA.
What is KOMTRAX and how does it work on Komatsu dump trucks?
KOMTRAX (and the upgraded KOMTRAX Plus 2 on larger trucks) is Komatsu's telematics system. It remotely transmits machine data — location, fuel consumption, payload, error codes, idle time, service hours — to fleet managers and dealers via satellite or cellular networks, enabling predictive maintenance, fuel optimization, and uptime tracking.
What safety and operator-assist features do modern Komatsu dump trucks have?
Newer models like the HD465-10 and HD605-10 include Auto Retard Speed Control (ARSC) for safe downhill driving, hill start assist, throttle lock (cruise control), waiting brake, payload meter (PLM) with overload alarm, full LED lighting, ABS (optional), wet multi-disc brakes on all four wheels, and a 4-point seatbelt option. Komatsu's KTCS traction control on HM-series ADTs improves grip in mud and on slopes.
What is the fuel efficiency like on Komatsu dump trucks?
Komatsu states the newest HD465-10 and HD605-10 deliver up to 6% better fuel efficiency than the previous -8 generation, thanks to tuned SAA6D170E-7 engines and Economy / Economy Light operating modes. Articulated HM models use hydrostatic transmissions optimized for smoother power transfer and reduced fuel consumption during loading cycles.
