The Minetruck MT5010 exits from the Stawell portal after a 9 km uphill drive.<br />
a tight turning circle, saving on backing<br />
out trucks in the limited space underground,<br />
<strong>and</strong> is a lot less tedious to<br />
drive, being much faster than the old<br />
machines.<br />
The engine on the MT5010 is electronically<br />
controlled for maximum fuel<br />
efficiency, minimum exhaust emissions<br />
<strong>and</strong> continuous diagnostic monitoring.<br />
This control system, along with an electronic<br />
transverter, provides smooth <strong>and</strong><br />
precise gear changes.<br />
In addition to the selection of Cummins<br />
as the engine supplier, Atlas Copco<br />
has put the MT5010 through a series of<br />
more than 40 performance-enhancing<br />
upgrades to the engine, powertrain, cab,<br />
suspension, structural body, <strong>and</strong> systems,<br />
which dramatically increase engine <strong>and</strong><br />
component life. Servicing is fast <strong>and</strong><br />
simple, thanks to easy access to filters,<br />
test points, <strong>and</strong> other parts which require<br />
regular maintenance.<br />
Continuous support<br />
The routine performed by the mine’s<br />
maintenance team includes checking<br />
main functions after each 12-hour shift,<br />
as well as more thorough services at 125<br />
hours, <strong>and</strong> the recommended intervals<br />
at 250 hours.<br />
The MT5010 trucks, despite their<br />
arduous working situation, are acknow-<br />
ledged by Stawell management as being<br />
the best performing trucks on site, with<br />
the highest t/km <strong>and</strong> excellent availability.<br />
As a result, the MT5010 trucks now<br />
constitute 70% of the hauling fleet.<br />
Where problems have been experienced,<br />
the mine knows it can rely on<br />
support from Atlas Copco.<br />
If they need a part, or a question an-<br />
swered, Atlas Copco provides a true,<br />
24-hour service, seven days a week, <strong>and</strong><br />
treats every enquiry with the correct degree<br />
of urgency.<br />
MelBOurne, auSTralia<br />
A technical training course on the<br />
MT5010 was conducted at the mine by<br />
Atlas Copco to further enhance the expertise<br />
of the maintenance staff. Many<br />
of the participants reported back that<br />
it was the best on-site training they had<br />
ever received from any equipment sup-<br />
plier, observing that Atlas Copco underst<strong>and</strong>s<br />
that aftermarket service <strong>and</strong> support<br />
is an important complement to any<br />
sale.<br />
Future plans at Stawell include further<br />
exploration <strong>and</strong> deeper development<br />
work. In the next four to five years it is<br />
planned to increase the mining depth to<br />
at least 1,300 m.<br />

Atlas Copco is grateful to the management<br />

their assistance in the production of<br />
