Komatsu
Chile S.A. found special meaning in the 2008 delivery of a new unit of the 930E
electric drive dump truck. This sale consisted not only of the acquisition of
new equipment for a long-standing customer, but it also marked a milestone for
the Chilean market as the 200th 930E electric drive dump truck Komatsu currently
operates in the expansive national mining field.
Mr. Manuel Lattes, product manager
for mining trucks of Komatsu Chile S.A., explains, “This major milestone
began in the 1990s when Chile received its first 930E electric drive dump truck,
which has since evolved into the 930E-4 electric drive dump truck. The model’s
high availability, performance and operation attributes, as well as low maintenance
costs, have made it the favorite of leading mining companies.”
Komatsu Dominates the Super-Large Electric Mining Truck Market
Within the super-large electric mining truck market, Komatsu 930E electric drive
dump trucks with a load capacity exceeding 290 tonnes (320 U.S. tons) are a major
presence in Chile’s leading mining operations. Mr. Lattes confirms that “of
the total number of super-large electric mining trucks in Chile, Komatsu possesses
a large share of the market for this kind of equipment with two competitors sharing
the remainder of the market.”
Komatsu’s electric drive dump trucks
rely on a device to control speed on steep grades through an electro-dynamic
retarding system that alleviates the need to replace worn-out components of the
brake system, compared to the retarding systems of mechanical trucks. This provides
additional safety to the truck operator and equipment.
Mr. Lattes adds, “The
electric propulsion system of Komatsu trucks does not require the ‘speed
changes’ typical of mechanical trucks. The continuous propulsion motor
system of Komatsu 930E electric drive dump trucks is based on induction electrical
motors, an alternating current and GDY106 wheel motor installed in each wheel
of the rear axle. A self-ventilated main alternator GTA41 coupled to the 2,014
kW (2,700 HP) diesel engine generates the electric current used to drive the
motors. This is another important design advantage that when paired with high
productivity and lower operation costs has made the Komatsu 930E electric drive
dump truck the market leader.”

Komatsu Announces Autonomous Haulage
Project with Rio Tinto
Komatsu Ltd. announced on January 18, 2008
that they will provide Rio Tinto with the FrontRunner® Autonomous Haulage
System for use at Rio Tinto’s Pilbara iron ore operations in Western Australia.
This is the second FrontRunner® autonomous installation using Komatsu’s
flagship 930E-4 electric drive dump truck, as Komatsu has already supplied the
first fleet to Codelco in Chile. The trucks navigate the complex mining environment
to deliver a 290-tonne (320-U.S.-ton) payload of overburden and ore without drivers,
revolutionizing productivity and mine operations, especially at mines where it
is difficult to secure sufficient manpower because of their locations.
The deployment
of the FrontRunner® system to Rio Tinto further demonstrates Komatsu’s
ability to deliver highly engineered, cutting-edge solutions with products and
services to meet the challenging tasks of its customers around the world.
