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.

— 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. •
