Caterpillar Paving Technology Maximizes Productivity
Customer input is the driving force behind many recent technological
improvements that are engineered and built into Caterpillar's new paving,
compaction and cold-planing products on display at bauma in Munich,
in hall B6 and in the adjoining external area.
“Customers tell us they want technology with function—technology
that helps them improve their productivity and their bottom lines,”
says Jim McReynolds, President, Caterpillar Paving Products. “Our
ultimate goal is to provide customers with solutions that reduce their
owning and operating costs.”
Products on display showcase Cat® Paving technology, and the advantages
it helps deliver.
Cat Grade and Slope
Many new Cat pavers and cold planers feature Cat Grade and Slope technology,
engineered to help paving crews precisely lay and mill material. Cross
coupling provides a consistent slope despite elevation changes. The
technology is easy for both paver and cold planer operators to understand,
and for crews to utilize.
The Mobil-Trac undercarriage, available on many new Cat pavers, provides
best-in-class traction, with the highest travel speed and the best maneuverability.
The system helps ensure work is completed quickly, and pavers can perform
under varied and demanding conditions.
Redirection of fumes
Independent researchers recently concluded that as much as 92 percent
of fumes are removed or redirected from Cat pavers by the exclusive
Cat Fumes Management System. The fumes are redirected from operators
of both the paver and the screed.
Cat Compaction Control
Cat Compaction Control is featured on new Cat soil compactors, Cat tandem
vibratory compactors and Cat pneumatic rollers. Cat Compaction Control
provides operators with information to help them ensure high quality
compaction is achieved. For soil compactors, the basic system provides
compaction measurement using either Compaction Meter Value (CMV) or
Machine Drive Power (MDP) technology, with the ability to augment the
system with GPS mapping capability. For tandem vibratory rollers and
pneumatic compactors, the system provides pass-count information and
GPS mapping, enabling the operators to achieve more homogeneous and
effective compaction by ensuring the proper number of passes are made.
Features beyond pass-count information are available, including infrared
sensors on the front and rear to continuously measure asphalt temperatures.
The accumulated data may be stored for later analysis so processes can
be examined and adjusted.
Cat Compaction Control with Machine
Drive Power (MDP)
Machine Drive Power (MDP), an exclusive technology, is available
on new Cat B-Series soil compactors. It performs well on most jobsite
applications and soil types: fine, granular and cohesive. It works on
smooth drums and can be used on padfoot drums and smooth drums equipped
with a padfoot shell kit. It is unique in that it measures compaction
with the vibe system on or off.
MDP measures rolling resistance as an indication of soil stiffness.
It measures closer to the depth that the machines are able to compact.
It also measures closer to lift thickness. The measurements are less
impacted by the dampening effect of cohesive soils, so it can be used
on padfoot machines.
Cat Compaction Control, whether using CMV or MDP measurement, can also
utilize a Global Navigation Satellite System (GNSS), such as GPS, to
provide positioning information to map pass count, coverage and compaction
measurement details. This data can be stored for review at a later time.
“We continue to leverage our decades of experience in the paving
industry, and also to listen to our customers and, with their help,
develop technology that provides solutions,” McReynolds says.
“As we develop new and improved technologies, we always ask ourselves,
'How can we make them easier for customers to utilize on their jobsites?'
At Caterpillar Paving Products, the goal is developing technologies
that are so advanced they work effortlessly behind the scenes to greatly
improve product performance and reduce owning and operating costs.”
New Cat® D6K2 Benefits from Refined Blade, Fuel Economy, Productivity.
The new Cat® D6K2 Track-Type Tractor delivers unmatched finish grading
performance and improved fuel economy. New Stable Blade Control feature
utilizes technology which complements operator blade control input,
making it the best finish grading tractor in the industry. Eco Modes,
both forward and/or reverse, improve fuel economy up to 22% depending
on the applications for lower operating costs. The new D6K2 uses the
powerful Cat C6.6 ACERT™ engine that meets Stage IIIB and Tier
4 Interim emissions requirements. K2 models feature hydrostatic drive
with Traction Control, which reduces track slip at maximum load. New
wider blades allow more ground to be covered in one pass and provide
up to 8 % productivity improvement in slot dozing applications. New
manual adjustable pitch allows the operator to control blade pitch fore/aft
for maximum productivity in various material conditions.
The K2 models blend these new features with the basic field-proven design
of their K Family predecessors, a design that includes single-lever
travel/steering control, spacious operator's station with standard air
conditioning with cab-equipped, single-lever blade control, Cat Sealed-and-Lubricated
Track (S<) or Cat SystemOne™ undercarriage for lowest undercarriage
cost per hour. The D6K2 benefits from the recently introduced undercarriage
improvements of the D6K. The combination of eight bottom rollers and
two carrier rollers allow for a smoother ride and better finish grading
capabilities at a higher speed.
Net power ratings are 97 kW/130 hp at 2,200 rpm. The new C6.6 ACERT
engine features Air To Air After Cooling, a new electric fuel priming
pump, and a passive regeneration system for emissions reduction.
Stable Blade Control supplements the operator's blade-control input,
helping to reduce operator effort and fatigue, while increasing productivity
in finish grading applications. The Stable Blade Control feature remains
activated unless cancelled by the operator. For even more productivity,
the blade pitch adjustment design has been simplified to allow the operator
to adjust blade pitch, for example, selecting a more aggressive setting
for hard blade loading or pitching the blade rearward for more blade
carry capacity. The D6K2 offers wider VPAT blades (both standard and
foldable versions), which can boost productivity as much as 8%.
The new Eco Mode system for the D6K2 model can improve fuel economy
by up to 22 percent by reducing engine speed when maximum rpm is not
required. Eco Mode has two settings - Forward/Reverse or Reverse Only
- that are selected via the rotary throttle. Once set, Eco Mode automatically
controls engine speed at optimal levels, rapidly delivering back maximum
engine speed and power when required.
Traction Control is an operator-activated system that reduces track
slippage under heavy load by sensing and controlling track speed, resulting
in fewer situations where operator must lift the blade to prevent track
slip. The benefits include higher production, less undercarriage wear
and reduced operator fatigue. Undercarriage configurations include XL
(Extra Long) and LGP (Low Ground Pressure) versions, with an LGP version
that features 760 mm (30-inch) track shoes.
For the ultimate in operator comfort, an optional package provides a
heated/ventilated seat. Electro-hydraulic seat-mounted controls isolate
the operator from vibrations and the new armrests can be easily adjusted.
For increased productivity and efficient grading and contouring work,
the D6K2 can be equipped with the optional Cat AccuGrade™ system
for automated blade control. AccuGrade can use laser, total station
or satellite positioning systems as the guidance source. AccuGrade is
designed to reduce the need for surveying, to eliminate rework and to
unburden the operator when doing finish grading. AccuGrade has demonstrated
itself as a solution to reduce overall machine operating costs in doing
more, and accurate work with less fuel burned.
The State of Nigerian
Dredges: A New Dredge Repair Yard.
Many dredges being
offered by dredge owners for contracts in the Nigerian industry right
now are far from healthy. There are stories of dredges being paid for
and on mobilization to site, they begin to manifest serious problems
of disrepair. For many days or weeks or months, the client cannot have
his milestones met because the dredge is down while efforts are being
made to buy spare parts or to bring experienced mechanics to perform
Describing this ugly situation, Sir Isaac Chuks, CEO of Funq Tai Engineering
Company, summed it up that many “Nigerian dredges work for two
hours and spoil for five hours”. Read
