Cold mix plant produces more
 Wirtgen
bills its new KMA 200 portable cold-mix plant as a highly mobile,
200-ton-per-hour unit that can make several types of asphalt blend products,
using emulsions or foamed asphalt, and a variety of other materials to
enhance strength and performance. In addition to its greater production
capacity, the KMA 200 improves on the KMA 150 with a better arrangement of
components and by powering all components with a fully diesel-hydraulic
drive. The heart of the new machine is a modified, low-wear, twin-shaft
continuous mixer, allowing a mixing capacity of 200 tons per hour. The
mixing plant is driven by a 175 horsepower diesel engine. The unit’s
integral water tank is 1,188 gallons — a 50% increase over the KMA 150
capacity.

Improved ‘First Response’ system
Introduced in 2002 as an all-purpose snow and ice control unit, the First
Response 3-N-1 snow and ice control system has been improved for 2004,
according to Henderson Manufacturing. The unit now has a completely enclosed
cabinet to house all pumps, valves, flow meters, the auger drive system, and
related components. Also upgraded: dual 7-inch diameter variable pitch
augers to convey granular material; wider bottom and counter-rotating augers
to break up frozen materials and help prevent bridging; better directional
control and a dump over feature for the end of a run; and fully baffled
liquid reservoirs to improve steering stability.

Smoother turns and travel
Bobcat’s new
ZHS compact excavators are the first in the industry to feature an
all-hydrostatic drive system, with separate piston pumps and motors for the
right and left tracks. The benefits, says Bobcat, include better torque
control for dozing, smoother turns under a load, and more gradual turns on
surfaces like asphalt and concrete. In addition to the FastTrack drive
system, the ZHS units feature Zero House Swing — a zero-tail-swing design
in which even the corners of the house stay within the track footprint when
the house rotates. The first two ZHS models are the 8,024-pound 430 ZHS and
the 10,555-pound 435 ZHS.

Wheel loader line launched
 Liebherr
Construction Equipment has introduced four wheel loader models to the
North American market. The new line ranges from the 162-horsepower L 538 to
the 261-horsepower L 580 in size. Though new to this market, the Liebherr
loaders are well established in Europe and, the company says, are
distinguished by their low operating costs. Key features include a
well-balanced overall design concept for longer component life, and an
advanced hydrostatic travel drive that minimizes wet brake disc wear and
uses tractive force control and limited slip differentials to reduce tire
wear.

Data logger improves ownership
 John
Deere claims its new Machine Information Center on-board data logger
gives excavator owners more data than any other system on the market, which
leads to improved productivity and minimized operating costs. The MIC
consists of an on-board logger, a cable and software kit for accessing the
logged data via a Palm Pilot, and an MIC Dataviewer for the owner’s PC to
summarize and manage the data. The data logger is standard; the cable and
software kit are available from Deere dealers.
The on-board data logger captures up to 10,000 hours of data, which the
software converts into charts, graphs, and reports. Alarms and faults,
engine speeds, hydraulic and coolant temperatures, pump pressures, hours of
operation, and swing/travel/front operation times are stored. Fleet managers
can use the data to evaluate how well the machine is being used and identify
opportunities for operator training.

More power
Husky Hydraulic Hammer has rolled out its new Series II breakers ranging
from 200 to 1,200 foot-pounds in impact energy. Several models in the new
line sport higher impact energies than their Series I predecessors, and all
models offer improved serviceability due to a significant reduction in
parts, according to Husky. The power surge comes from a redesign of the
operating piston, main valve, and internal porting, and a slight increase in
the low-pressure nitrogen gas charge. Husky says the hydraulic input flow
range of the Series II hammers has been widened so that the same unit can be
run on a relatively low-output compact excavator or a high-output skid-steer
loader without compromising performance.

High-powered portable
 Morbark
says its new 6600 Wood Hog horizontal grinder balances ease of portability
with the highest production rate in its class. Available in power ranges
from 760 to 1,000-horsepower, the unit features a sliding fifth-wheel pin
and movable third axle to make transportation easy. Morbark says the 42 by
67-inch hammermill, equipped with heavy-duty 28-inch rotors, is laser cut
for better durability and more precise tolerances, and that the 6600 has the
largest infeed in its class.

Less damage from utility cuts
 Ditch Witch
has introduced its new FX60 Vacuum Excavation System to the utility trade as
a tool that can quickly dig potholes to locate buried utilities with a
high-pressure stream of water. The company says the FX60’s “soft
excavation” can access damaged utilities with a small, neat hole without
danger of damaging pipes or cables. The unit’s vacuum function can be used
to remove drilling fluids, or to clean out manholes, catch basins, vehicle
wash pits, and grease traps.

Alternative fuel sweeper
Schwarze
Industries now offers alternative-fuel-powered versions of its A7000 and
A8000 regenerative air municipal sweepers. Both models are powered CNG-fueled
engines. Like the company’s CNG-fueled M6000 mechanical broom sweeper,
these alternative-fuel models are in compliance with the South Coast Air
Quality Management District’s Rule 1190, which covers alternative fuel
usage.

Year-round pothole patcher
 Pro-Patch
Pot Hole Patchers have the unique ability to transport hot or cold asphalt
pre-mix material and road oils at controlled temperatures, according to H.D.
Industries. The truck-mounted TCM 415-160 has a PTO-driven hydraulic system
to operate the machine’s jack hammer, screw conveyor, oil pumps, asphalt
agitator, hydraulic doors, and a variety of hydraulic tools such as saws,
tampers, and water pumps.

Lighter, smoother tailgate
East Manufacturing’s new aerodynamic Genesis smooth-sided dump trailers
are now available with a new smooth-walled tailgate that is said to be much
lighter than traditional sheet-and-post designs, yet just as strong and
durable. The smooth surface of the tailgate is easy to clean and, according
to East, leaves nowhere for dirt, mud, snow, or ice to build up.

Upgrade to ‘Super’
The “S” in Wirtgen’s
new WR 2500 S Road Reclaimer and Soil Stabilizer stands for “super,”
according to company promotions. The top-of-the-line model has a new
fuel-injection system that boosts its 12-cylinder engine’s power from 610
to 670 horsepower (455 to 500 kW). Wear is minimized in the redesigned,
reinforced cutter housing by means of multiple wear plates, and the cutter
drum has easier-to-service bolt-on end rings. Cooling performance, operator
comfort, and ambient particulate levels have been improved, and a new dual
cyclonic air precleaner will extend the service life of the air filtration
system.

Economical soil stabilization
Fecon says its
Stabilization series of attachments are just as effective — and more
economical — than purpose-built soil stabilization machines. Available in
models ranging from 100 to 380 horsepower, Fecon stabilization attachments
are said to be capable of mixing and milling earth to depths of as much as
16 inches. They feature heavy-duty rotor construction, carbide tips, and are
available with PTO or hydraulic power options.

Improved service body
An exclusive one-piece side pack (patent pending) constructed of 10-gauge
galvanneal and a unique internal hinge design give the new Titan 38
unparalleled strength and corrosion resistance, according to Auto
Crane. The body can support a 38,000-foot/pound crane. Its compartment
capacity has been increased 12% and can be ordered with custom fit drawers.

New mini-excavator line
 Five
mini excavators have been added to the Ditch Witch line. Models range in
size from 0.9 to 4.5 metric tons with digging capabilities ranging from 4
feet, 11 inches to 13 feet. All five models have tight tail-swing design and
removable counterweights for zero tail-swing operation.
