Truck Driver 'Didn't Know' He Was Dragging a Car

Blog Commentary by Tom Berg, Senior Contributing Editor

It appears the car has been pulled up under the trailer's corner by its spinning tires. Like many truck-car accidents, the car's driver seems to be at fault. But still....

Checking the mirrors should be a normal part of driving, but maybe 'Mike' had other things to look at than the car caught up in his trailer. Tom Berg has more in the Trailer Talk blog. READ MORE

Where Did the North Koreans Get Those Missile-Toting Trucks?

Blog commentary by Tom Berg, Senior Contributing Editor

Civilian version of Wanshan's WS51200 is meant for off-road hauling of timber, ore and fuel. But paint it olive-drab and outfit it with an erector-launch body, and the rough-terrain truck becomes a military threat.

Where did North Korea get its trucks and trailers to haul weapons? On the internet there are reports that the trucks and tractor-trailers were made in China, with – yikes! -- American and German components. Tom Berg explores the question in the Trailer Talk blog. READ MORE

Drop Decks, Aluminum Transition Radii, and the Romans

Blog by Tom Berg, Contributing Senior Editor

Can you see a Roman arch in the radius under the transition area of this Mac single-drop aluminum trailer? The radius directs weight away from the 90-degree joint above.

I looked at the transition radius on a Mac aluminum drop deck and it occurred to me that the radius is an arc, a portion of an arch – that engineering marvel devised by Roman engineers more than 2,000 years ago. READ MORE

Semitrailer Inventor August Fruehauf to Enter Automotive Hall of Fame

The semitrailer, Hemmings.com says, “triggered the wide-scale distribution of modern consumer goods."

August Fruehauf, a German immigrant and blacksmith, found inspiration for the semitrailer from the horses he shoed.

Fruehauf, as a blacksmith, noted that horses that pulled rather than carried loads were in better shape. He reasoned that trucks would likewise last longer if they towed rather than toted loads. READ MORE

Second Connector Needed for Tractor-Trailer Communications?

Stopping distances could be even shorter and stability better with more precise signaling between tractors and trailers, which an extra cord or LAN would allow.

Second electrical cable (lower right) on this beverage trailer carries power to charge its liftgate batteries. It coud also carry signals to a high-performance braking system.

Increasing need for electronic communications between tractors and trailers could require use of a second electrical line, say brake-performance specialists. READ MORE

Jackknifes Happen Often on Dry Roads, Too

This all occurred in just a second or two, though it took several seconds for the rig to stop, the trailer jammed against a corner of the tractor’s sleeper.

The rig lurches to a stop with probable damage to the tractor's sleeper and who knows what else. No word of any injuries.

Anti-lock braking systems are supposed to keep brakes from locking, but this time didn’t. Why might that be? READ MORE

Regulations Will Widen Use of Aero Devices, Wabco Says

Operators will realize solid fuel savings that will pay for the devices in under two years, unless the devices are damaged or need other repairs.

Trailer skirts are common on vans and reefers, and soon will become standard equipment. Other devices will be necessary to meet federal requirements by 2021. Photo: Tom Berg

Starting Jan. 1 of next year – fewer than nine months from now – all new 53-foot box-type trailers will come with trailer skirts, like ‘em or not. Tom Berg has more in his Trailer Talk blog. READ MORE

On Slick Pavement, ‘The Sliding Wheel Wants to Lead’

Whichever wheels are skidding on a tractor-trailer will want to get in front and take the rest of the rig with it.

ABS is supposed to prevent jackknifes, but somestimes can't when pavement's icy, as on this freeway in the Northeast a few weeks ago.

When encountering a slick road, it’s a real good idea to test the brakes to see how the rig behaves. Then you'll know what to expect in a real application. READ MORE

Old Sayings Apply While Driving Through Bad Weather

Slow way down in blinding conditions? Sure, but not so suddenly that you get rear-ended. Even better, park the truck in a safe place and wait out the storm.

Maybe that container simply had to get there no matter what. But now its contents have been badly shaken up in this tipover.

Fog and whiteouts caused by blowing snow can often be anticipated by considering the time of the year and what regularly happens along certain stretches of roadway. READ MORE

The Twin 33s Idea Returns. Will It Fly This Time?

Revival might be riding on enthusiasm over President Trump’s pro-business beliefs and his promise to improve America’s infrastructure.

A pair of 33-foot pups would have 10 feet more floor space for cargo than a set of 28s, as the labels on this concept trailer show. And two 33s would have 13 more feet than a single 53-foot van. Will truckload shippers demand their use?  Photo: Tom Berg

A pair of longer pups would haul more than two 28-footers, so LTL carriers and shippers are in favor. But truckload carriers still want no part of them. READ MORE

Tanker Crashes, Driver Dies, Road Damaged, But a Fair News Story

"Tanker trucks hauling food, fuel and chemicals are part of the backbone of the economy. To some people, though, they are a growing danger." That's called even-handedness.

News report of a recent fatal tanker crash painted a sympathetic picture of the truck driver who was killed and explored the sometimes dangerous world of transporting hazardous materials.  Photo: Tom Berg, from WCMH-TV news video

Who's to Blame in This RR Crossing Wreck?

Remember, “Stop, look and listen”? It's still a good idea for any driver.

The gates came down after the wreck. And what a mess! Note that the impact yanked the fifth wheel off the tractor's frame. That means the fifth wheel's jaws hung onto the lead trailer's kingpin.

Newscasters focused on the non-working crossing lights and gates. But shouldn't the truck driver have looked for a train? Tom Berg has more in Trailer Talk. READ MORE

Trucks Block Possible Terrorism in D.C., New York City

Why Are So Many Trailers Just Sitting There?

Very few of the trailers seen from the passenger train were at loading docks; most sat in long rows, side by side, looking forlorn and forgotten.

European Cargo Securement Devices are Diverse

American and Canadian rules require stuff in a van or reefer to be tied down, but it’s out of sight and can be overlooked by inspectors.

Koegel equipped its Cargo display trailer with various types of load-securing devices for several kinds of freight. This one includes curtain sides and a fold-up roof tarp for side and top loading. Photos: Koegel

Like here, tying down the goods is a concern in Europe, because a dominant German trailer builder recently displayed a van with numerous securement options aboard. Tom Berg has more in his Trailer Talk blog. READ MORE

Powered Trailer Axle Provides an Off-Road Boost

Run off the tractor's wet kit, the hydraulically driven axle adds traction in rough conditions and can eliminate 4x4s used by some European operators.

For Tankers, 'Vapor Recovery' Works Two Ways

Hauling fuel for this company is a lot easier than dealing with heavy freight containers, says driver Jeff McMannus.

He stood at an open pipe at the tanker and held his hand in front of it, checking air as it flowed inside. During product loading, vapor-laden air is drawn out of the tanker to keep it from bursting. READ MORE
