Komatsu Articulated Dump Truck

12 models in this series

The Komatsu Articulated Dump Truck series from Komatsu comprises 12 models. Rated output ranges from 251.5 to 459.3 hp.

Komatsu articulated dump trucks HA250 to HM400 – the number as payload in tenths of a tonne: HA of the 1990s, HM300 to HM400 since 2001, generations -1 to -5, SAA6D125 and SAA6D140 engines, 179 to 334 kW

Komatsu's articulated haulers carry two codes: HA for the range of the 1990s (HA250-3, HA270-3) and HM for the generation from 2001 (HM300, HM350, HM400), with which Komatsu seriously attacked the market of the 30 to 40 tonners. The number gives the payload in tenths of a tonne – HM300 carries about 30 t, HM350 35 t, HM400 40 t – the digit after the hyphen the generation from -1 to -5, where the -5 brings Stage IV; M0 is a market variant. The engines are Komatsu's own six-cylinders from the excavator programme: S6D125 and SAA6D125 with 11 litres in the HM300, SAA6D140 with 15.2 litres in the HM350 and HM400.

The register lists 12 versions with 179 to 334.1 kW from six-cylinders of 11,001 to 15,242 cm³, torque from 1,600 to 1,990 Nm at 2,000 to 2,200 rpm, lengths from 9,303 to 11,302 mm, widths from 2,502 to 3,536 mm and heights from 3,340 to 6,520 mm.

Komatsu's hallmarks are drive to all six wheels with engageable locks, traction control that regulates wheel slip via the brakes and the powershift transmission with lock-up converter; the HM400s run in quarries, earthworks and small open-pit mines where rigid-frame trucks have too little ground clearance.

On used trucks, operating hours, play in articulation joint and oscillation bearings, the condition of body cylinders, brakes and transmission and the tyres, which are the biggest cost item on these vehicles, are what count; parts run through Komatsu dealers worldwide.
