Komatsu HD785 to 960E: rigid haulers split between mechanical and electric drive
At Komatsu, "HD" marks the classic rigid-frame dump trucks with mechanical drivetrains, while the model number indicates payload class: the HD785 carries a manufacturer-rated payload of 92.2 tonnes. Models with the "E" suffix, such as the 830E, 930E and 960E, use diesel-electric drive instead – the diesel engine powers a generator that feeds two wheel motors on the rear axle through cabling, with no mechanical transmission.

The number after the dash, as in 730E-7 versus 730E-8, marks the build generation. The "Komatsu Rock Truck" bucket here groups 35 live-listed models across both drive types, from smaller rigid HD haulers to the largest electric-drive trucks.
The technical spread is wide: among 33 models with recorded displacement, values run from 12,175 to 78,000 cm³, and cylinder count among 25 models spans 6 to 18 – figures consistent with the huge drive engines used in electric haulers. Among 19 models with recorded power, output ranges from 171 to 2,495 kW.
Buying used, operating hours and the engine's service history matter most; on diesel-electric models, also check the traction alternator and wheel motors. Models such as 830E, HD780, 730E-8 and 930E-4 appear across the listed inventory.
Generation (the dash number), drive type (the E suffix or its absence) and payload class (the model number) together make up the full code of a Komatsu haul truck.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
