While driving on a highway recently, a
truck trailer with an oddly shaped back
end caught our eye. We pulled alongside to
check it out and saw an extension attached
to the back of the trailer that looked like
the top of a cardboard box with its flaps
partially folded inward. It was a
“TrailerTail,” a patented device developed
by ATDynamics that reduces low-pressure
suction drag directly behind the trailer.
According to the manufacturer, the attachment increases fuel efficiency by an average of 6. 6 percent at 65 mph. When the
device is paired with trailer “skirts” or
“wings” that hang below the vehicle’s sides,
fuel savings can reach 10 percent.
The fuel savings from aerodynamic
attachments are substantial, according to
FPInnovations’ Performance Innovation
Transport (PIT), a nonprofit engineering
and research group that serves the North
American trucking industry. The
Montreal-based organization has been
conducting tests on trailers equipped with
side skirts and undercarriage aerodynamic
devices for five years. In its most recent
tests, PIT found that trailers with side
skirts consumed 6. 69 percent less fuel on
average than similar vehicles without
skirts. Trailers with undercarriage aerodynamic devices consumed 1.43 percent less
fuel on average than similar units without
the deflectors, PIT said.

It’s awfully hard to resist the siren call of a shiny new lift truck, especially the high-tech marvels that are on the market today. But not
everyone needs or can afford the latest and greatest, so dealers, manufacturers, and third parties offer used trucks for sale, lease, or rent.
These days, used lift trucks are hot commodities both here and
abroad. And dealers and resellers are finding it a challenge to meet
demand, according to Allen C. Rawson, president and CEO of Atlas
Toyota Material Handling Schiller Park, Ill. In addition to being one of
the largest-volume Toyota dealers in the United States, Atlas is a wholesaler of used trucks of all makes.
“Selling them is easy,” Rawson said in an interview. “It’s buying them
that’s the challenge.”
The main reason used trucks are in short supply is that during the
Great Recession, sales of new forklifts in the United States declined by
approximately 50 percent from previous years’ levels, says Dave Moran,
vice president at Crown Equipment Corp. “This impacted the supply of
four- to five-year-old forklifts available for the used truck market
today,” he explains.
Rawson said the two years following the recession produced the lowest
level of trade-ins and lease returns—the source of many of the trucks in
rental fleets—he had seen in 15 years. As a result, wholesale prices of used
trucks have been rising, which in turn is bumping up retail prices, he said.
That doesn’t mean the rental market has dried up, though. Rawson
expects to see continuing strong demand and is actively seeking out
good-quality used equipment nationwide. Other dealers and manufacturers are working to keep adequate stocks available. Crown, for one,
updated its rental fleet in 2008; with the addition of lease returns, its
supply of used equipment is “healthy,” Moran says. ;

With so much high-speed, high-tech material handling equipment
around these days, it might seem the lowly caster wouldn’t merit much
attention. Not so, according to Hamilton Caster, which makes a wide
variety of casters, wheels, carts, and trailers that keep things rolling in the
warehouse and elsewhere. The company’s blog, aptly named “The
Revolution,” shows that casters can be surprisingly interesting.
One blog entry, “Even the Statue of Liberty Runs on Hamilton
Casters,” tells how the longtime food and souvenir concessioner on the
island where Lady Liberty stands has relied on the company’s casters
and powered carts for half a century. Recently, Hamilton replaced casters that had been in service there for 50 years.
Another, especially timely post, “ 11 Ways Hamilton Powers Football
Season,” explains that Hamilton casters can be found under the Sunday
Night Football mobile broadcast desk and in the Arizona Cardinals’
new scoreboard, and that they helped to carry the Lombardi Trophy
onto the field after this year’s Super Bowl.
