Replacing Rivets with Adhesives Yields Smoother Sides That Could Save Fuel

Computational fluid analysis interpreted air flow over the trailer panels’ surfaces, finding some drag produced by rivet heads.

As trailer aerodynamics improve, the small amount caused by air flow over sidewall surfaces will become more important. Art via Lord Corp.

Lord Corp., which makes bonding adhesives, has done research that indicates eliminating rivets from a trailer’s walls might cut aerodynamic drag by about 1%. READ MORE

Crash Argues for Better Impact Guards, and Better Driving

You’d think the woman driving the van would’ve seen the rig sitting there with its tail and marker lights on, and its red-and-white reflectors aglow from her van’s headlights.

In spite of the underride, the van's driver door opened and the motorist removed that way. Photo: Tom Berg, image via WCMH-TV

United Technologies Execs Tackle Food Waste Problem

One-third of all food produced goes to waste. If it weren't, it's possible that nobody would go hungry.

Proceeds from book sales will be donated to food charities, UTC says. Art via United Technologies

“If food waste were a country, it would be the third largest emitter of greenhouse gases behind China and the United States." Tom Berg's Trailer Talk blog looks at a new book on food waste whose authors are with the parent company of Carrier Transicold READ MORE

Trailer Weight Cutting Suggestions Total 2,500 Pounds

How many of these items are usable in your van trailers?

Aluminum crossmembers instead of steel can save 203 pounds in a van or reefer, according to ICCT's list. Another 430 pounds can be slashed by using aluminum in the upper coupler assembly, but the kingpin remains steel. Photo: Tom Berg

While poring through more than 1,300 pages of proposed regulations, staffers found themselves immersed in details of trailer design, including weight reduction. READ MORE

Containers Get Second Lives as Homes, Offices, Warehouses

These steel boxes are exceptionally strong, fire resistant and weatherproof, and deserve to be repurposed instead of going to scrap.

Containers are made of heavy gauge steel and make excellent structural components. And they’re far cheaper and “greener” than buying traditional materials like lumber for that purpose. READ MORE

The Army Uses Serious Rigs to Haul Armored Vehicles

Armored vehicles can “road march” to battlefields, but suffer high rates of wear and tear when doing so. It’s far better to carry them.

The U.S. Army operates some of the more serious tractor-trailer combinations in the world, as Tom Berg explores in his Trailer Talk blog. The M1000 gooseneck trailer, for instance, weighs 50,000 pounds before it's even loaded. READ MORE

Designing, Testing Tires for Drop-Deck Trailers Challenging

Spread tandems sometimes generate extreme lateral forces, and drop-decks use smaller sizes that are especially vulnerable to damage.

ULX40 Follows Trend Toward Mechanical Suspensions on Vans

New composite leaf springs should last longer than steel and ride almost as well as air-ride, SAF-Holland says.

Composite springs vary in shape and thickness across their length. ULX40, with 40,000-pounds capacity, comes with drum or disc brakes.

Air-ride's more complex and requires more maintenance, so some fleets that watch costs very closely never got on the air-ride band wagon. READ MORE

Are Trailers More Aerodynamically Important than Tractors?

Experts agree that wind drag on trailers is more significant than what the tractor faces.

Piggyback Equipment at Pennsylvania’s Toy Train Museum

Trucks, on the road or on flatcars, are often part of model railroads, as Senior Editor Tom Berg found at the Toy Train Museum.

There was a time when railroads were in the motor transport business, as their parent companies recognized that freight was being grabbed by fast, flexible long-haul trucks and they might as well grab some of the revenue. READ MORE

EkoStinger: A Different Way to Beat the Wind

An arrow-shaped aero device diverts wind away from the tandem, while a covering of the frame rails and crossmembers reduces turbulence there.

Unlike most skirts that are stationary, the stinger moves with the tandem as it’s slid fore and aft, so it smooths air flow no matter where the tandem is set, said the system’s inventor. READ MORE

Why Safe Coupling Procedures Matter

Four people died when their car ran into a semitrailer sitting on a busy highway. How'd it happen?

For a better chance at properly hitching the fifth wheel onto the kingpin, hook up and charge the air hoses, then set the trailer’s brakes before backing onto it.  Photo courtesy of Con-way

It could've been driver error, mechanical failure or both, and we won't know for a while. But it sure matters. READ MORE

Metal Coils Snuggle Safely into Cradles on This Specialized Trailer

The heavy loads can't roll off because they're automatically blocked aboard.

Rubber-lined well accommodates big, heavy metal coils, which are usually strapped down. Sliding shelter covers the load.

Out-of-Control Doubles Make Spectacular Video

On black ice, all the anti-lock braking systems in the western world can't do much to control a multi-trailer combination.

The truck had gone over the divider by this point coming to rest, only moments before being struck from behind.

This video is so graphic that parts of it, shot by a motorist along the New Jersey Turnpike, were picked up by ABC and CBS in their evening newscasts one day last week. Thankfully, no one was hurt. READ MORE
