Putzmeister built the high-capacity unit in Germany, and it'll work in Texas for Western Concrete Pumping.
February 2, 2016
Most pumpers are mounted on straight trucks, some with multiple axles, but this large, heavy one is better carried on a long 10-axle rig.

Another trailer axle would add 11,000 pounds of gross weight, but does it make dollars and sense?
September 21, 2015
The strongest argument against heavier rigs is the lack of payback due to low revenue from stingy shippers. That's the "market" at work.

Computational fluid analysis interpreted air flow over the trailer panels’ surfaces, finding some drag produced by rivet heads.
August 26, 2015
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%.

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.

Spread tandems sometimes generate extreme lateral forces, and drop-decks use smaller sizes that are especially vulnerable to damage.
July 2, 2015
Dropdeck trailers with spread-axle tandems are torture on tires. Tom Berg explores one tire maker's quest to design a product to stand up to the beating in his Trailer Talk blog.

Trucks, on the road or on flatcars, are often part of model railroads, as Senior Editor Tom Berg found at the Toy Train Museum.
May 7, 2015
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.

An arrow-shaped aero device diverts wind away from the tandem, while a covering of the frame rails and crossmembers reduces turbulence there.
April 28, 2015
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.
