Flanders’ crowd motors have shown documented
electrical life of greater than 100% over competitive
motors. This supports longer uptime, reduced
maintenance cycles and lower cost of repairs.
Hoist motors
Flanders-designed M24 and M22Amotors are drop in
replacements for competitive hoist motors. The motor is
designed to provide additional torque and deliver
exceptional life compared to the OEM motor. Current
applications have seen nearly 40 000 hr of continuous
operation with no maintenance or rework. The
commutator incorporates Flanders’ exclusive design that
ensures no degradation in life after performing turn and
undercut refurbishment. Unlike competitive motors that
may actually weaken the armature after rework, the
motors will continue to outperform their rivals.
Results for end users
The Freedom upgrade can provide increased reliability,
machine up-time and lower cost of maintenance.
Flanders estimates that the Freedom system will yield
an 8 – 10% increase in productivity (short t/sec). This
translates to more material moved at a lower cost per
short ton.
A recent upgrade in the Powder River Basin on a
P&H 4100XPC provided a 24% improvement in
performance – or short t/sec. as measured in this
example. The shovel cycle time was reduced on average
by more than 20%. This performance has been repeated
in subsequent upgrades. This example was conducted
in a coal application; therefore, performance results
may vary depending on a variety of external conditions
(i.e. shovel utilisation, dig conditions and truck
dedication). Following the significant improvements
that this particular mine owner encountered, it has
decided to order and install another system, and are
also currently considering a third shovel upgrade.
“The Flanders Freedom system upgrade allowed us
to turn one of our lower-performing shovels into the
highest-performing shovel in our fleet. In addition, we
have not seen any increased maintenance costs as a
result of the increased productivity of the machine,”
commented the Electrical Manager at the mine.
Each critical component of the Freedom upgrade
improved the overall performance of the shovel. This
allows the upgrade configuration to be selected in
accordance with a mine operation’s specific
requirements.
Return on investment
Capital improvement expenditures are limited and
new equipment purchases are nonexistent. Therefore
it is essential to get the most out of current machines.
The typical payback on a Freedom upgrade is
typically less than twelve months depending on a
customer’s requirements, while the impact to the
bottom line is measurable and immediate.

SLOPE CONVEYOR
BELTS
Slope conveyors are the most cost-effective
means of transporting material from an under-
ground mine to the surface and – if necessary –
from the surface back underground at the
same time.
PHOENOCORD Steel Cord Conveyor Belts
with integrated PHOENOTEC active protection
system and with highest fire resistant properties
are the perfect choice for underground
slope conveyors.
