The electric panel is now housed in an
ATEX-approved flameproof box that can also
incorporate a monitor screen where profile
control is used. Sandvik is in the process of
gaining national approvals for this enclosure, with the aim of having a standardized
installation on all its machines, worldwide.
Two types of water spray are available,
the choice depending on local regulations.
The Incentive Temperature Potential (ITP)
system recycles motor-cooling water into
the spraying system, while the Jet Pipe system uses both cooling water and compressed air for dust suppression.
The first MR341 is scheduled for delivery to New World Resources' 2.9-millionmt/y ČSM mine in the Czech Republic
shortly, with a three-month trial scheduled
for the second quarter of the year. The
largest single component—the main
frame—weighs around 7 mt, with a twoweek underground assembly schedule possible with three-shift activity.

Gearboxes Offer Performance
Improvements for Mine Use
Gear and drive specialist David Brown says
its CX series gearboxes are designed to operate at extremely high defined levels of
torque, speed, power and thermal ratings,
exceeding competitor performance and representing a new, unique best-in-class
model. According to the company, the
advanced technologies designed into the CX
series provide key product solutions for mining operations, including up to four times
longer bearing life; up to 20% greater thermal capacity, reducing the need for ancillary
cooling equipment; precision gear tooth profiles that reduce noise and maximize power
transfer; an optimized, cast housing; and a
unique flippable design with modular
mounting options. Customers also benefit
from the company's new three-year extended warranty package, which is available for
any gearbox brand and model—even those
of competitors—and provides access to
David Brown's global network of service and
repair centers. The extended warranty also
covers new installations of gearboxes
designed and manufactured by David
Brown; and includes the option to install a
remote conditioning monitoring system
(CMaS) that gathers critical information
while the gearbox is in operation, warding
off the risk of unexpected failure.
