ing than conventional hard, rigid square<br />
trays. “Damage is quite a bit less on our<br />
bodies, because it will absorb the shock,<br />
it will bend, it will spring, but it will come<br />
back into shape,” says Turner. “On square<br />
bodies, it will crack, or affect the chassis.”<br />
In the event of an accident, Hercules<br />
trays can be easily replaced with a new<br />
side panel, unlike square bodies. “With a<br />
rigid square body, it can be a major repair<br />
or you can just about write the body off,”<br />
explains Turner.<br />

Grueling Field Tests<br />
At <strong>DT</strong> <strong>Australia</strong>, the company believes<br />
that one of the best ways to test its trays<br />
is to put them in use at mine sites. During<br />
one particularly grueling 18-month-long<br />
field trial with one of <strong>Australia</strong>’s leading<br />
mine sites, results were benchmarked,<br />
and the performance and savings the<br />
Hercules’ lightweight and durable bodies<br />
offer to the mining industry was evident.<br />
From operational performance to significant<br />
savings through increased load<br />
ability, reduced maintenance, repair and<br />
overall operational efficiencies, there are<br />
many benefits to mines from using <strong>DT</strong><br />
Hercules trays. Truck carrying capacity<br />
improves by 10 to 15 percent. Fuel costs<br />
are lowered 6 to 11 per cent per tonnes<br />
moved. Along with reduced tyre costs,<br />
users can expect a reduction in truck<br />
downtime due to less body maintenance.<br />
Customers also report that spillage is significantly<br />
reduced during, haulage, at the<br />
loading point and at the dump site.<br />
Wear Management Programme<br />
Unlike some other companies, <strong>DT</strong> <strong>Australia</strong><br />
has a unique Wear Management<br />
Programme, which manages the service<br />
life of the Hercules Trays. On mine sites,<br />
trucks hauling and dumping tonnes of<br />
iron ore, coal and other materials will<br />
all show the effects of wear and tear in<br />
time. In regular square trays, wear maintenance<br />
is costly in more ways than one.<br />
Repairing trays is expensive, and trucks often<br />
experience considerable down time, reducing<br />
mine effectiveness and profitability.<br />
Under <strong>DT</strong>’s Wear Management Programme,<br />
the company’s trays undergo<br />
periodic assessments, with any signs of<br />
wear being monitored and patterned.<br />
When necessary, wear plates or tiles are<br />
installed at varying thicknesses depending<br />
on the wear rate. This adds back only<br />
the weight of steel worn from the floor<br />
(which carries the bulk of the weight and<br />
payload), prolonging the service life of<br />
the body without compromising load carrying<br />
advantages.<br />
“Our philosophy is: wear<br />
first, and then replace.”<br />
“We have a specific Wear Management<br />
Programme, because unlike other bodies,<br />
our bodies don’t require wear liners<br />
to start with, and that’s another area<br />
where we get a significant weight advantage,”<br />
says Turner. “Our philosophy<br />
is: wear first, and then replace. We do<br />
a free wear measure check and report<br />
as part of our warranty within the first<br />
12 months of operation. Providing the<br />
wear is managed and the floors are maintained,<br />
the bodies will require minimum<br />
maintenance.”<br />
At <strong>DT</strong> <strong>Australia</strong> , the company is capable<br />
of manufacturing customised trays ranging<br />
from 80 o 360 tonne super truck capacity,<br />
and everything in-between. “We<br />
can build up to about 250 cubic metre<br />
capacity,” says Turner. “This is why it’s<br />
mine-specific; it depends on the density<br />
of the material. But we can build 225,<br />
190… it really depends on the material, so<br />
we don’t overload the truck.” Floor thickness<br />
varies with the material the dump<br />
trucks are required to carry.<br />
Weight Advantage<br />
From the quality of the steel they<br />
use to the skills used to cut and assemble<br />
them, there are many advantages<br />
for mining companies using<br />
the Hercules trays, with the greatest<br />
being weight. Putting it simply, lighter,<br />
more durable curved trays mean<br />
dump trucks can carry more payload,<br />
increasing profitability over typical<br />
rigid square trays.<br />

curved trays mean<br />
dump trucks can<br />
carry more payload,<br />
increasing profitability<br />
over typical rigid<br />
square trays.<br />
“We can offer on average a 10 to 15 per<br />
cent weight advantage, which purely<br />
relates to the payload,” says Turner.<br />
“On a smaller truck, you get an extra<br />
10 to 15 per cent in them; on a larger<br />
truck, you’re talking 50, 60, 70 tonnes<br />
extra. Our bodies are lightweight because<br />
of how they are engineered and<br />
designed, not just taking steel out of<br />
it.” By making trays lighter, there is<br />
no need to add tailgates or other unnecessary<br />
“dead weight,” resulting<br />
in greater productivity, safer hauling,<br />
and lower operating costs.<br />
Since <strong>DT</strong> <strong>Australia</strong> focuses its development<br />
efforts on the Hercules<br />
range, the company’s Research and<br />
Development focusses on making its<br />
trays more durable, lighter, and of<br />
the highest possible quality. “This is<br />
our own patented design, and all our<br />
dollars go into continually improving<br />
this body, so that’s a significant benefit,”<br />
comments Turner. “Our product<br />
is engineered and designed to<br />
be used in all types of mining applications<br />
all over the world. Through<br />
our engineering and design work<br />
solutions, we believe our bodies offer<br />
greater longevity, and higher payloads<br />
because they are lighter. There<br />
are others out there, but the curved,<br />
innovative design of the Hercules<br />
has evolved over 10 years and we are<br />
producing our Phase IX body. Our<br />
competitors simply don’t reach our<br />
performance levels. No one else can<br />
tick ALL the required boxes!”<br />
Additionally, the company offers firstclass<br />
service, and a solid, 12-month<br />
warranty on all structural parts, with<br />
checks of all welds, joints, pivot areas,<br />
and main rails. “We measure the<br />
floor thickness to see what’s worn,<br />
and with that, we can determine how<br />
quick it’s wearing, and when the likelihood<br />
of the need for some wear management<br />
would need to be applied.<br />
Depending on the abrasiveness of<br />
the material, that could be anywhere<br />
from 5,000 hours to 30,000 hours. To<br />
apply our wear package is minimum<br />
work. To apply big plates of steel to a<br />
square body is a major job, very costly<br />
and requires longer down time.”<br />
Just as the company<br />
has evolved over<br />
the years, so has the<br />
Hercules tray.<br />
Just as the company has evolved<br />
over the years, so has the Hercules<br />
tray. Even with countless tests and<br />
computer analysis, the true test<br />
comes from being out in the mines.<br />
“That’s the only way to get a true<br />
indication,” says Turner, “and our<br />
bodies are becoming more and more<br />
popular. We’ve got over 1,000 bodies<br />
worldwide now, and some of those in<br />
excess of 50, 000 hours old, so we’ve<br />
got a very good history in all types of<br />
materials and conditions of how these<br />
bodies perform, and what can be expected<br />
with life and maintenance. It’s<br />
really been a work in progress.”<br />
