According to Mining News Pro - Komatsu has added low-emission tier 4 engines that cut fuel
consumption by up to 7 per cent compared with previous models to two of
its trucks.
The engines vary slightly between the two truck
models. Komatsu’s 40t capacity HD405-8 truck uses the SAA6D140E-7 engine
(383kW) and the larger 63t capacity HD605-8 truck uses the SAA6D170E-7
(540kW) engine.
The Komatsu-designed engines use an electronic
control system using vehicle sensors. The condition of the engine can
be checked in this way from a monitor inside the operator’s cab.
Owners and fleet managers can remotely assess this data using Komatsu’s telematics monitoring system, Komtrax.
“Operators
have unmatched control and safety in even the most difficult operating
conditions, through our integrated transmission and braking system —
which is recognised as being the best in the industry,” said Richard
Feehely, Komatsu Australia national business manager, quarries.
Energy-saving
measures have been used to reduce fuel consumption, such as an
auto-idler, choice between power and economy modes, and an ecology
guidance feature.
“Our 40t and 60t class trucks have built a
reputation over many years for being the safest, most cost-efficient and
productive trucks available; these two new generation tier 4 trucks
will further build on this, with their ultra-low emissions, even lower
fuel consumption, and detailed data capture through on-board monitoring
and Komtrax,” said Feehely.
