as standard equipment on each new Doosan
mini excavator.
Doosan also introduced its Next Generation
7-Series crawler excavators to North America,
off ering increased performance, fuel effi ciency,
operator comfort and serviceability.
These include the 14-metric-ton, reducedtail-swing
DX140LCR-7. In the popular mid-size
category, DX350LC weighs approximately 35
metric tons, making it ideally suited for a variety of
trenching applications on infrastructure job sites,
and commercial and residential developments.
Doosan also re-designed and expanded its
innovative 7-Series wheel loader lineup.
On the smaller end, the 2.6-cubic-yardcapacity
DL200-7 features a hydrostatic drive
system for enhanced fuel effi ciency, machine
positional control and reduced wear on the brakes.
The new DL220-7 is built with a standard Z-bar
lift-arm linkage system, ideal for digging, heavy
lifting and general construction tasks. Operators
can choose from three power modes to further
adapt its performance to the application.
DL250-7's smart technologies amplify its
material-handling abilities, while maximizing
power and effi ciency. Exceptional lift heights
and generous bucket capacities help operators
power through the heaviest loads.

All CASE Construction Equipment G Series wheel
loaders - with 4.5L, 6.7 and 8.7L diesel engines
- are now approved for use with B20 biodiesel
directly from the factory.
Wheel loaders in these size classes are used
extensively in construction, public works, road
and bridge construction, concrete and asphalt
production, aggregates and agriculture.
The announcement comes after extensive
testing by FPT Industrial, which confi rmed that
these engines performed comparably to the same
engines powered by off -road diesel. The study
highlighted no adverse eff ects to the engines.
" Biodiesel is one of the fastest and most
effi cient ways that we can benefi t from
Road Widener's Off set Vibratory Roller Attachment
Brings Heightened Safety, ROI
Road Widener LLC., Delafi eld, Wisc., manufacturer of innovative road
and utility construction equipment, off ers the industry's fi rst Off set
Vibratory Roller attachment.
The attachment's off set, patented design allows the host machine
(most loaders, graders, compact track loaders and skid steers)
to drive safely on fl at ground while compacting sloping shoulders,
ditches, trenches and other hard-to-reach areas alongside the road.
" With traditional compaction machines, every degree of slope is
felt by operators as they navigate through uneven terrain, resulting
in an increased risk of tipping, " said Lynn Marsh, president of Road
Widener. " The Off set Vibratory Roller combats that by providing a viable alternative that allows contractors
to quickly and effi ciently get the job done without risking an accident. It's a game changer. "
The Off set Vibratory Roller compacts a variety of materials including stone, asphalt, gravel
and topsoil. Once attached to a host machine's lift arm and connected to its hydraulics/remote
control, all aspects of the attachment - including height, angle, extension and compaction
adjustments - can be operated by a single crewmember.
With a total reach of 9 feet, the attachment can be purchased with a 2-, 3- or 4-foot-wide
drum. All drums can pivot up to 30 degrees, reach up to 30 inches below the mounting point, and
are interchangeable. This means road crews can take on jobs of varying sizes and aggregates by
purchasing additional drums, instead of investing in multiple, self-propelled machines with engines
that can fail. Additionally, the vibratory feature operates between 2,500 and 3,500 vibrations per
minute for optimal compaction.
Along with no risk of tipping, the Off set Vibratory Roller helps reduce workers' comp claims,
lower insurance premiums, and increase contractors' safety ratings, versus self-propelled compaction
machines - all necessities for bidding on and winning jobs.
Since it operates without an engine, powertrain, or any associated parts of its own, the
attachment reduces maintenance by 90 percent over traditional machines. It's also more easily
transported and off ers unmatched return-on-investment. *

renewable energy today, " said Terry Dolan, vice
president-North America, CASE Construction
Equipment. " FPT has long been at the forefront
of off -road diesel engine technology built
to lower emissions and reduce the carbon
footprint - and the fact that our diesel
equipment that already features these engines
can help contractors, municipalities and farms
better achieve their renewable goals is a massive
step forward. "
B20 biodiesel is the most prevalent blend of
biodiesel available in North America. *
