ustomers all around the globe are
relying on Metso Minerals for solu-
tions, equipment and services to
their rock and minerals processing needs.
Tampere, Finland-based Metso Minerals is
a key subsidiary of parent company Metso
Corporation. You’ll find Metso Minerals’ cus-
tomers crushing, feeding, screening and wash-
ing aggregate in more than 150 countries.
“Our contractor and quarry customers
count on our crushers, every day,” explains
Jussi Sjoblom, global source manager for
Metso Minerals. “Our machines have to be
reliable. They have to work.”
Sjoblom is currently located in Columbia,
S.C., where the company has just completed
a manufacturing facility for the LT200HP
mobile crushing plant, powered by a
Cat® C13 ACERT engine.
The Lokotrack LT200HP crusher operates
on an intermittent rating of 310 bkW
(415 bhp) at 1,800 to 2,100 rpm. The
LT200HP mobile crushing plant is a rather
new addition to the Lokotrack line and is
designed for secondary and tertiary crushing.
The company plans to move part of produc-
tion of the LT200HP from its Tampere, Finland,
location to the new plant in Columbia, S.C.
Columbia will manufacture the LT200HP mainly
for the North and South American markets.
Plans to move production of two additional
track-mounted crushing plant models is also
being discussed.
rely on the provenThe move to a United States produc-
tion facility is a major undertaking and was
carried out to bring the assembly closer to
the growing U.S. market. It is also one that
Metso Minerals carefully planned. Metso
Minerals operates additional business lines
in Sweden, Germany and the United States.
The company also took careful consider-
ation to rely on proven suppliers to assist in
making a smooth transition for the LT200HP.
Caterpillar, and its network of Cat dealers
both in the United States and Europe, was
one of those key suppliers.
“We have an excellent partnership with
Metso Minerals, which includes trust and a
strong working relationship,” notes Markus
Leppanen, segment manager power systems
for Finland Cat dealer Wihuri Oy Witraktor.
Leppanen explains that instead of send-
ing its own service staff all over the world
to service Metso customers’ Cat engines,
Wihuri Oy Witraktor relies on dealers within
the worldwide Cat dealer network for such
service. This leaves Wihuri Oy Witraktor free
to focus on the necessary logistics to supply
Metso Minerals with the engines they need
when they need them.
“We also focus on design, application
and service support for our customers,”
says Leppanen.

ers have a large Cat dealer network to access
— and one very close to the company’s new
South Carolina home. Blanchard Power Systems
in Columbia, S.C., has stepped in to help the
OEM with its needs in the United States.
“We rely heavily on our Cat dealers, first in
Finland and now in the United States,” stresses
Sjoblom. “The communication between Cat
dealers and us as a customer has been a part
of allowing us to successfully transfer our pro-
duction of the LT200HP to South Carolina.”
the whole piCtureMetso Minerals’ expertise covers the pro-
duction of aggregates; the processing of ores
and industrial minerals; construction; and
metal and waste recycling.
The company’s mobile crushing line, com-
prising of about 30 different models, is pow-
ered almost exclusively by Caterpillar industrial
engines. Utilized in a variety of quarrying and
in-pit crushing applications, these track- and
wheel-mounted crushing plants are available
in jaw, cone or impact crushing configurations.
Metso Minerals manufactures a wide range
of crushing equipment and therefore requires
a wide range of diesel power. To date, the com-
pany is utilizing Cat 3056E, C6.6 ACERT, C9
ACERT, C13 ACERT, C15 ACERT and C18 ACERT
engine platforms. They have also built a few
crushers with Cat 3412 gensets.
Metso Minerals’ mobile crushing plant
crushers are mostly hydraulically driven, and
the Cat engines power everything from the
hydraulic pump drives to the tracks to the
conveyor to the crusher. The combination
of Metso’s advanced intelligent control (IC)
crusher automation systems, Cat engines with
ACERT Technology and Metso crushing technol-
ogy are designed to maximize production with
optimized fuel consumption.
The engines are currently shipped from
the Finnish Cat dealer Witraktor to the Finland
plant, where Metso Minerals packages them
into a power pack. The dealer equips the
engine with necessary auxiliary equipment and
modifications, programs the engine’s Electronic
Control Unit (ECU) according to Metso’s spe-
cific machine requirements and stores the
engine to wait for just-in-time delivery to Metso.
Metso’s own packing includes the engine,
gearbox, two to three hydraulic pumps, piping,
hydraulic oil tank, control box, side-by-side air
coolers, engine bed and engine cover.
“The power pack we supply is a plug-and-
play package for our manufacturing facility,”
says Sjoblom. “And our machines are a one-
touch operation for our operators,” he adds.
autoMation for effiCienCyUnique to a Metso Minerals’ mobile crush-
ing plant is the intelligent control system that
ensures the feeding of the crusher is a steady
and constant process at all times.
The IC system interfaces with the Cat ECU
(which stores engine diagnostic data, eliminates
speed variation and adjusts for cold starts, rapid
acceleration and smoke reduction) to keep
the engine running at a constant rpm (around
2,100 rpm). This continuous rating allows the
machine to crush all types of aggregate effi-
ciently and evenly.
Online information from the engine’s ECU
and the crusher’s IC system is available to
the operator for control and monitoring of the
crushing process, which can be started and
stopped with a single button.
“The crusher incorporates an easy-to-oper-
ate crusher automation system that optimizes
the crushing process control while allowing
maximum workload and reduced crusher main-
tenance costs,” concludes Sjoblom. •
the crusher automation system interacts with the engine’s ECu to continuously monitor preselected parameters to ensure maximum per-formance and trouble-free operation.

thE Cat® C6.6 aCERt EnginE iS an ExCEllEnt ChOiCE fOR link-BElt CRanES — nOw and in thE futuRE.
ExtEnding tOwaRd thE Sky
and thE futuREt takes years of experience to develop the expertise to design and
manufacture cranes that lift heavy loads several hundred feet in the
air. And it takes a special kind of know-how to design cranes that
perform these functions in rough-terrain environments. Link-Belt, head-
quartered in Lexington, Ky., has the process down to a science.
As a crane manufacturer with more than a century of experience
under its belt, the company currently manufactures an entire line of
mobile telescopic and lattice boom cranes. For the power needs in
its rough-terrain and hydraulic truck cranes, Link-Belt has turned to
Caterpillar industrial diesel engines.
divERSE appliCatiOnLink-Belt currently uses the Cat® C6.6 ACERT engine in its
RTC-8065 Series II and RTC-8090 Series II cranes and the
Cat 3126B in its RTC-8075 rough-terrain crane. The Cat
C11 ACERT powers Link-Belt’s HTC-8640SL and HTC-8660
Series II hydraulic truck cranes (on-highway cranes).
The application for these cranes is diverse, from con-
struction to material handling to equipment rental — in
both on- and off-highway models.
A main difference between the rough-terrain and
hydraulic truck cranes is their travel speed and mobility.
The hydraulic truck cranes are made to travel down the
highway at 55 to 60 mph while the rough-terrain mod-
els’ top traveling speed is around 20 mph. The rough-
terrain models are equipped with off-road tires and
tend to be operated for longer periods of time on
a single jobsite, often on a long-term rental basis.
The hydraulic truck cranes, due to their mobility,
can travel to multiple jobsites in a day.
i
a Cat® C6.6 aCErt engine powers the link-Belt rtC-8090 series II crane. the engine is rated at 167.8 bkw (225 bhp) at 2,200 rpm.
5IndustrIal EngInE PowEr rEPort • sPrIng 2007
Regardless of application or model, the
cranes’ engine powers both the drivetrain and
the hydraulic system. Each crane’s four-pump
hydraulic circuit allows simultaneous function
of the boom hoist, winch and swing, while the
piston motor hydraulic hoist system delivers
hoisting power.
The most demand is placed on the engine
when the crane is maintaining its maximum
travel speed, on or off the road. The engine
operates at an intermittent rating during crane
operations, where it will typically complete a
series of functions, stop for awhile and continue
with another series of functions.
StROng CuStOMER pREfEREnCELink-Belt relies on the voice of their custom-
ers to guide the crane development process.
“The preference for a specific engine in a
crane can evoke substantial emotion in our
customers,” explains Richard Shultz, Link-Belt
product design manager. “Rough-terrain crane
customers want a dependable powertrain that
works in many types of environments and
incorporates a strong service support network.
Owners of truck cranes (cranes that travel on
highways) are even more vocal about their
choice of engine. They demand good power-to-
weight ratios, superior fuel consumption and
a great service support network. We felt that
Caterpillar power could help us meet all our
customer requirements in these crane models.”
unifORM pOwER REquiREMEntLink-Belt’s newest Cat engine is the C6.6
ACERT. The company is utilizing the engine at a
rating of 167.8 bkW (225 bhp) at 2,200 rpm in
rough-terrain crane models. Link-Belt has been
working with Caterpillar for about five years.
The C6.6 ACERT replaces the Cat 3126B in
the RTC-8065 model and is the engine of choice
for the new RTC-8090 model. Both models
now standardize on the Cat C6.6 ACERT, which
provides 727 lbf.ft. (986 Nm) of torque at
1,400 rpm.
According to Shultz, the Cat C6.6 ACERT was
chosen for several specific reasons:
• Ratings. “The C6.6 ACERT engine pro-
vides a range of horsepower and torque ratings
that fits a large number of our crane models,”
says Shultz. “Most of our models fall into the
150- to 230-hp range, and this Cat engine fits
these horsepower requirements perfectly, allow-
ing us to utilize the engine in several different
crane models.”
• size. The C6.6 ACERT has 10% more
displacement in the same size envelope as its
predecessor engine.
Compactness is especially important because
in the Link-Belt rough-terrain cranes, the engine is
almost integrated into the crane’s frame (see pic-
ture on this page.) Protected in part by an engine
cover, there isn’t a lot of extra space.
“The compactness of the C6.6 ACERT allows
it to fit into several of our models. It has out-
standing range of power and torque ratings that
meet many of our needs. It’s a compact engine
with good power ratings for its size and weight,”
notes Shultz.
• emissions. The transition from a
Tier 2/Stage II engine (3126B) to a Tier 3/
Stage IIIA engine (C6.6 ACERT) has been a rela-
tively smooth one, according to Shultz, although
it has presented a few challenges.
“Tier 3/Stage IIIA emission requirements have
added complexity to the cooling system design of
our engine package,” Shultz notes. “But Caterpillar
has been extremely helpful in this area.”
And even with the redesigned cooling sys-
tem, Link-Belt has managed to keep the cost of
a Tier 3/Stage IIIA engine in line with its previous
engine model. “We have been able to maintain
cost parity with this Cat 6.6 ACERT engine,” says
Shultz. “Even though Link-Belt has added new
technology to the powertrain, we have attempted
to minimize the cost impact to our customers.”
futuRE planS in MindWhile the Cat C6.6 ACERT engine meets
Tier 3/Stage IIIA emissions standards, Link-Belt
is always looking ahead to future emission
standards. The company is keeping the Cat C6.6
ACERT, as well as additional Cat engines, in mind.
“We work diligently to be in full compliance
with all applicable emissions standards,” says
Shultz. “For example, we install lower-emission
on-highway engines in all of our truck crane
applications even though legally we could install
an off-road engine.
“We are also familiar with electronic engines
due to our experience in the on-highway appli-
cations,” he concludes. “Electronic engines bring
new features to rough-terrain cranes that we
have taken advantage of, such as fuel efficiency,
noise reduction and performance.” •
link-Belt hydraulic truck cranes, like this HtC-8660 series II, rely on Cat® C11 aCErt engines to power the drivetrain and the hydraulic system. the engines are rated at 261 bkw (350 bhp) at 2,100 rpm.
the compactness of the C6.6 aCErt engine fits well within the HtC-8660 series II crane’s frame.

ACErT™ TECHNOLOGY
rom the very beginning, Cat® engines have been
on the cutting edge of technology. For example,
Caterpillar introduced electronic engine control — and
turbocharging — years ago. That innovative spirit contin-
ues today in Cat engines with ACERT™ Technology.
ACERT Technology began as a better way to reduce die-
sel engine emissions, and it has culminated into a revolu-
tionary engine design breakthrough that actually enhances
diesel engine performance by burning fuel more precisely.
The key to ACERT Technology is injection timing.
Instead of injecting fuel in one burst, ACERT Technology
delivers fuel in a series of smaller microburst injections.
As a result, Cat engines with ACERT Technology are pro-
grammed to achieve maximum performance and efficien-
cy with lower combustion temperatures, which reduces
emissions and prolongs the life of lighter,
more power-dense engine platforms.
ACERT Technology also varies the
injection timing based on factors like
engine load and speed. This allows
the engine to maintain optimum
performance under a wide
range of operating conditions.
As technology advances,
Cat engines with ACERT
Technology continue to remain
ruggedly durable, reliable
and cost-efficient. Caterpillar
continues to leverage technology
to boost performance and efficiency,
while retaining operational simplicity,
reducing emissions and maintaining long
service life. And the unparalleled worldwide Cat
dealer network continues to back it all up. •
