of operation such as the torque generated.
“This also makes it possible to become
much more accurate when specifying
components like drive motors – where
we can specify size and capacity in a more
scientific way,” states Mayhew-Ridgers.
“We might find, for instance, that a smaller
motor will start the motion just as well as
a larger unit allowing a saving on capital
costs and energy consumed.”
The test frame can also be used to test
different condition monitoring solutions,
by installing the necessary tools and con-
ducting computer monitoring; even the
performance of newly developed isola-
tors under the machine can be tested with
results escalated to suppliers about how
their items could be further enhanced for
better results.
He says the company’s compact design
of a dual motor base – where the motor
base can stand on a pedestal between
two machines and drive them both – also
makes it easier for a mine’s process plant to
accommodate this technology.

New rigid dump truck tyres from Goodyear
Goodyear is introducing the RM-4B+ OffThe Road (OTR) tyre range
for rigid dump trucks in the Europe, Middle East and Africa (EMEA)
region. After successful performance in the United States, the
brand-newOTR range, which includes several new sizes – among
them a 63-inch version which was recently presented at the
MINExpo in Las Vegas – is now available to customers in EMEA.
The range comprises five sizes for vehicles operating in
severe conditions such as those typically encountered in min-
ing and quarrying.
The Goodyear RM-4B+ range features 170-level tread depth
and optimal tread zone stiffness for excellent wear performance.
The innovative CycleMax tread rubber compound ensures cool
running and is enhanced by tread lug blading for additional heat
resistance. Heat resistance is also a benefit of the centreline chan-
nel, which gives added lateral traction.
Other tread features include interlocking blading for high sta-
bility and angled main grooves for forward and lateral traction.
Particularly important for severe operating conditions are the extra thick sidewalls, which
provide excellent protection against friction and impact.
“Our new RM-4B+ OTR tyres feature our latest technologies in materials, design, con-
struction and manufacturing. Thanks to this they provide high performance in all areas
resulting in a high number of operating hours and therefore reduced costs per hour to our
customers,” said Tracy Maclear, Marketing & Brand Manager, Goodyear South Africa.
The tyres are all tubeless radials with load capacities from 12 150 kg up to 63 000 kg.
