High-tech sweeper in compact size
 Tennant says its new Sentinel street sweeper brings to the market the
high-tech advantages of its award-winning Centurion in a smaller and
lower-priced package. Together, the two models form Tennant’s StreetMaster
series of outdoor sweepers.
The Sentinel is an 83-horsepower, highly automated four-season sweeper.
In addition to one-button sweeping, Tennant
claims it has exceptional debris
removal abilities, and minimizes dust. A new option, the operator-adjustable
Vario Sweeping Brush, permits sweeping around obstacles and on top-of-curb
areas not accessible to other sweepers. Its center-suspended floating main
broom automatically adjusts to road surface variations.
In addition to push-button sweeping mode selection, the Sentinel’s
sweeping system self-adjusts to brush wear levels. The unit meets PM10 dust
requirements with a dry filtering system that controls dust generated by the
main brush, even in sub-freezing temperatures. The unit’s cab is
insulated, soundproofed, and pressurized with air filtered to 3 microns for
easy breathing
The combination of a short wheelbase and four-wheel power steering gives
the unit a turning radius of 13 feet.

All-in-one trailer/melter
Cimline’s new ServicePro line of trailer/melters features a large
storage area and the company’s 115-gallon HeatWave direct-fire melter. The
melter’s tube-fired heating system uses two 7-inch-diameter single-pass
flues that are 0.1875-inches thick and run 4 inches from the bottom of the
kettle. Cimline says the technology provides superior strength and maximum
heating surface, so sealant is heated quickly and evenly. The large,
lockable storage cabinet on the trailer can house all the tools needed for a
crack-sealing job and provides access from either side of the unit.

City-sized articulated hauler
 Volvo Construction Equipment says its new A25D articulated hauler has the
compact dimensions needed for working in confined areas like congested urban
job sites and tunnels and underground mines. The 4x4 truck has a wheel base
15.75-inches shorter than its predecessor, reducing its turning radius. An
optional hydraulic turn-around system further reduces the turning radius,
allowing the hauler to turn 180 degrees in just over 31 feet of space in
about 25 seconds.
The A25D 4x4 has a payload capacity of 26.5 tons and a top speed of 32.9
miles per hour. It has a 17-cubic-yard heaped load capacity, with maximum
ground pressure forces of 23 psi on the front wheels and 28.1 psi on the
rear. The 306-horsepower unit has a load-sensing hydraulic system that helps
it achieve a 19% rimpull increase and 14% productivity gains compared to its
predecessor.

New loader and tool carrier debut
Komatsu has introduced a Series-5 version of its WA250 wheel loader and
tool carrier. The new WA250-5 and WA250-5PT are now powered by a Tier-2

lower emissions, and a 15% drop in fuel consumption, according to the
company. Cabs have been expanded and enhanced with lower noise levels and
better climate control.

Fuel-efficient drum mixer
Dillman claims its patented Duo-Drum Mixing System boasts the industry’s
lower fuel cost per ton of hot-mix asphalt produced, regardless of burner
fuel type and aggregate moisture content. The company says Duo-Drums have
the largest independent counter-flow dryers manufactured, both in diameter
and length. Patented adjustable dryer flights allow for optimal veiling of
the aggregate in the dryer, and the Duo-Drum trunions have easy, single
point adjustment and use massive railroad bearings, according to Dillman.
Duo-Drum uses the latest Hauck Burners technology, which supplies 100% of
the air needed for combustion, resulting in decreased fuel costs and low
emission levels.
