Milling drum takes on extremes
Australian milling contractor Road Services of
Australia specializes in extreme jobs, such as removing more than 20,000
cubic yards of reinforced concrete with milling equipment. To complete such
work, the company has developed the Schibeci ultra-rugged milling drum for
severe service applications. Now available in North America through Roadtec
and MECOM, the Schibeci drums feature tooth-holding blocks that won’t fall
off or break off, even when the tool hits submerged objects such as steel
manhole covers.
The drums are said to require only annual
maintenance and to retain the same cutting pattern for their entire
lifetimes. The company says its smooth outer flight design reduces vibration
and drag, improving productivity and fuel consumption, and the drums remove
more material from the cut that other designs.
Schibeci drums come in widths ranging from 3-inches
to more than 16-feet wide and are recommended for working in asphalt,
concrete, reinforced pavements, and other media.

Sweeper body for do-anything chassis
 Schwarze Industries
is now offering its A7000
heavy-duty regenerative air sweeper with 8.4-cubic-yard hopper on a Unimog
U500 chassis. The A7000 body can be offloaded in about two hours from the

Municipalities commonly use the rugged Unimog chassis and a variety of
attachments to handle snow plowing, mowing, disaster relief, road
construction, underground cable laying, tree transplanting, and many other
tasks.

High-powered 8-foot pavers
 Terex Roadbuilding
says its Cedarapids 300 Series,
Tier 2 asphalt pavers rank among the most powerful in the 8-foot commercial
class thanks to an upgrade to a new 165-horsepower engine. The company says
the 352 rubber-tire model is the most productive in its class, with a top
paving speed of 366 feet per minute and potential production capacity of 758
tons per hour. Its track-mounted counterpart, the 362, can pave at up to 205
feet per minute. Other improvements in the series include a better
air-cooling system and a new muffler that reduces noise levels by three
decibels.

Redesigned landscape loader
John Deere has given its 210LE landscape loader a
new engine, a redesigned operator station, and body design changes to
enhance productivity, serviceability, and operator effectiveness. The
company says the new 4.5-liter engine gives the 210LE more power than
competing models. Owning and operating costs have been reduced by increasing
intervals between oil changes to 500 hours, using vertical spin-on filers to
simplify changes, and implementation of a new two-position tilt hood that
provides ground-level access to the engine and all daily service points. The
new cab has more legroom and the redesigned loader linkage is said to be
easier to use.

Work truck as office
Kenworth has announced a number of options to put
more sizzle in its mid-range T300 trucks, including a workstation. “Many
drivers, especially those making multiple stops in a day, use the cab as
their office, filling out paperwork and logging hours, for example,” says
Steve Gilligan, Kenworth marketing manager. Kenworth has created an optional
work station between the driver and passenger seat. The compartment opens up
and a small desk emerges. It has two 12-volt outlets to power computers and
other devices, and there is space to hang files and store clipboards, as
well as storage for work gloves or shoes underneath. In the closed position,
the unit has a beverage holder on top.

High-tech dozers debut
Komatsu’s new KomStat II line of small dozers
features the company’s electronic-control hydrostatic transmission and an
ergonomically designed joystick control system that features short levers
and light operating effort. Available in standard undercarriage, as EX-21
models, or in longer, wider PX-21 undercarriages, the new dozers range from
the 75-horsepower D31, to the 85-horsepower D37, to the 95-horsepower D-39.
Powertrain components are mounted to the frame with rubber damping pads to
soften vibration and minimize noise. Komatsu says the cab has the largest
volume in its class, and uses high internal air pressure to prevent external
dust from entering the cab environment.

Revolutionizes sand classifying
 GreyStone’s patent-pending, twin-tank,
sand-classifying control system allows plant operators to run two
classifying tanks from a single computerized control system. The twin-tank
controls use GreyStone’s patented Aggre-Spec III software package to
continuously monitor the feed and adjust the classifier discharge valves
based on percentages, rather than on a batch basis, providing for greater
spec product control.

Compact has quiet power
 Volvo’s new 5-ton EC55B compact excavator features a
roomy, quiet cab and a powerful 16-valve, 3-liter diesel engine. The company
says the new unit maintains low fuel consumption and low noise — 78 decibels
inside the cab, 98 dB outside. Standard features include an X-shaped
undercarriage for strength and stability, a safety-valve-equipped blade
cylinder so the blade can be used as a stabilizer, and optional safety
valves on the boom and dipper cylinders to prevent drifting.
