UG LOAD AND HAUL
The DUX DT-Series line of dump trucks ranging
from 7 to 50 t capacity now includes a smaller 5
t model designed and manufactured in
response to customer demand.
Measuring only 1,425 mm wide with 1,930
mm tramming height, the DT-5N (narrow
version) is powered with Deutz D914 L05 with
97.2 hp and features Rexroth hydrostatic
transmission. Also equipped with Kessler D41
series axles with spring applied hydraulically
released liquid force cooled multi-disc brakes
on each wheel end, “it is sure to provide
trouble-free service. The DT-5N's extremely
rugged design allows for five-year unlimited
hour warranty on frames, which comes
standard on all DUX trucks. DUX has long
history of designing and manufacturing
smaller-sized dump trucks and is looking
forward to delivering the new DT-5N to a US
customer within the next few months.”
about 17% smaller drifts since they do not need
the large ventilation ducts. This can be the single
biggest mine cost saving in the long run.”
On added infrastructure, Gaitonde told IM:
“Minimal infrastructure is required to locate one
charger and two batteries. The GE battery
exchange system does not require the use of
cranes or any other infrastructure to change out
batteries, allowing for charging and exchange of
batteries closer to the workforce. GE’s quick
battery change-out system allows for a battery to
be changed in 15 minutes. Most mines already
have the electrical infrastructure needed to
support the charging of batteries, meaning no
additional work would be needed to support the
technology.”
GE has conducted extensive 7T LHD testing at
its GE Fairchild facility in Glen Lyn, Virginia and
has run the vehicle on two separate occasions at
a local quarry to simulate shifts in the field. GE's
first commercial units are currently on their way
to be commissioned at mines in South America
and Canada.
On performance against peers: “GE 7T LHD has
been benchmarked to perform against the best
LHDs on the market although there has been no
head-to-head trial. We incorporated additional
improvements in our design to correct the
deficiencies or unmet customer requirements in
the currently available models.”
This is the first GE LHD to be launched for the
underground hard rock market. Previously, all
Fairchild products have been designed for the
coal market. Currently, the 7T LHD is the only unit
available for the UG hard rock market.
On larger machines and other options, GE
says it is committed to the electrification of
underground mines, “with a plan to offer a host
of products through our GE store to meet the
needs of our underground hard rock mining
customers”, however, there are no further
details. Equally, on the underground
development collaboration with Komatsu, the
company would only say: “Komatsu is a valued
GE customer and partner. We continue to
successfully collaborate with them on various
aspects of mining value chain and applications.”
Joy Global
Joy Global has LHD options in its range from 0.7
to 10 t and truck options ranging from 6.4 to 31.8
t. With the range still mainly based on acquired
MTI models, Joy is working on upgrading and
redesigning these machines with up to date
components and technology, while retaining the
positive attributes such as their robustness and
versatility. Bill Maki, Senior Product Manager –
Loaders and Trucks, told IM: “We are still
supporting the existing MTI fleet while we work
