has announced the release of the
980E-4 electric-drive haul truck – its largest-ever – with
a payload capacity of 363 tonnes (400 US tons).
Power for the 980E-4 comes from a Komatsu
SSDA18V170 Tier 2 engine, rated at 2611 kW which in
combination with its GE Mining dual IGBT electric drive
system provides a top speed of 60 km/h.
According to Scott Harrington, Komatsu Australia’s
National Product Manager, Mining, this engine provides
one of the lowest brake-specific fuel consumption (BSFC)
in this truck class.
Applications for this truck include iron ore, coal and
other resources requiring bulk material movement when
matched to large loading tools, to deliver the lowest
As with other trucks in Komatsu’s ultra class electric
drive haul trucks range, the 980E-4 was designed, de-
veloped and manufactured by Komatsu America Corp
at its Peoria operation in Illinois for customers around
“Komatsu was the first to introduce AC drive
systems for ultra-class mining trucks in 1996,
and has ever since continued to demonstrate to
our customers in Australia and globally the
incomparable performance and reliability that
Komatsu trucks provide,”
“The 980E-4 is based on the proven high
quality Komatsu design that will deliver excep-
tional productivity and outstanding availability
over the whole life of the asset, to provide our
customers with the lowest cost per tonnage
A number of major components on the 980E-4 are
common to Komatsu’s successful and well proven 960E-2
truck. These include the engine, radiator, alternator,
retarder and cab.
Other key components have been developed specif-
ically for the new 980E-4, engineered to meet the de-
mands of its 363 tonne rated payload.
These major component changes include larger wheel
motors and hydraulic components.
The new GDY108C wheel motors, based on GE
Mining’s proven GDY108B design, are longer to accom-
modate the 980E-4’s 44 inch rims and incorporate a
number of gearing and bearing design changes.
Hoist cylinders, steering cylinders and suspension
cylinders have all increased in capacity, ensuring that
with these trucks can maintain a known rated hydraulic
system pressure and Komatsu component design life
