Railcar Wins Swedish Steel Prize, But Wabash’s Entry Still Admirable

Blog commentary by Tom Berg, senior contributing editor

External spiral rails grab Helix Dumper's load-carrying tub and smoothly tip it to discharge the load, then set it back on the railcar's frame. This won the annual Swedish Steel Prize for Kiruna Wagon. Photo: Tom Berg, from Kiruna Wagon video

May 18, 2017

The Helix Dumper is a major advance and worthy of a prize. But I'd have voted for Wabash National's RIG-16 rear impact guard.

Airplane Hits Trailer in 'Amazing' Encounter

Blog commentary by Tom Berg, Senior Contributing Editor

The airplane left part of its landing gear, including a wheel and tire, near the left-front corner of the 53-foot van. Photo: Sandusky Register

May 11, 2017

The plane came in too low and its landing gear clipped the top of the South Shore van, tearing off and embedding itself in the roof and side panels. The plane continued on and its pilot put it down safely on its belly.

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.

April 7, 2017

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.

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.

March 29, 2017

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.

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.

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

March 5, 2017

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.

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

February 8, 2017

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.

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.

Managers strive for “productivity” and “equipment utilization,” but how many trailers are moving freight even half the time in their lives? Tom Berg's Trailer Talk blog muses on the number of trailers just sitting around.

November 14, 2016

There’s dropping trailers, as in hook-and-drop operations, and there’s dropping a trailer, as in whoops! In his Trailer Talk blog, Tom Berg looks at two recent product announcements aimed at addressing the potential of trailers coming loose from fifth wheels.

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.

November 4, 2016

“SAF Trak” axle is powered from the tractor’s hydraulic wet kit. On the trailer, two hydraulic motors, one at each axle end, turn the wheels to help get the rig moving in slippery conditions.

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.

October 14, 2016

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.

Trailer Aerodynamics Not Overly Popular, Study Shows

Among seven categories of fuel-savings devices for over-the-road rigs, trailer aero devices had the lowest acceptance rate, about 21%.

Trailer aerodynamic devices have caught on, but it apparently took the California ARB rules to force most fleets to begin adopting them. Photo: Tom Berg

September 12, 2016

It appears that it took a government decree to push operators into it, and it will take another set of rules to force further adoption of drag-reduction methods for trailers.

Phase 2 GHG Regs for Trailers Both Simple and Complex

Box-type and vocational trailers are both affected in 2018-27 rules, and the U.S. is the first country in the world to regulate them.

Flatbeds, among the vocational trailers newly regulated for fuel economy and emissions by the federal Phase 2 rules, will need tire pressure management devices and low rolling-resistance tires to comply. Photo: Tom Berg

August 24, 2016

Trailers have long been regulated for safety. But trailers’ contributions to fuel economy and reduced emissions are new matters for for federal authorities.

Whoa, How'd This Rig Hold Together?

It seems amazing that the tractor stayed hanging there instead of breaking loose and falling onto the street below. But fifth wheels and trailer kingpins are very strong.

Stronger Impact Guards Are Already Here

Canadian-spec "bumpers" have been standard on vans and reefers for a decade or more, so the feds' upcoming mandate for stronger equipment is not a big deal.

Is that bumper a Canadian- or American-spec? It could be either. Photo: Tom Berg

February 26, 2016

Only eight states allowed a truck to tow two trailers, but lengths varied and none of the eight were contiguous. Then congress added a provision in the FAST Act that legalized tandem towing in all states, and liberalized combination length.
