By Jack Roberts

Today’s dump trucks are smart, connected and integrated — but still tough enough to handle heavy loads in tough working conditions.

Hill Climbing's Easy for mDrive and 'Downsped' MP8 Diesel

Engine cruised at 1,300 rpm at 60 and 65 mph in 11th-direct and 12th-overdrive gears, respectively. Photo: Tom Berg

By Tom Berg

The Pinnacle-pulled rig weighed close to 80,000 pounds. So how did it pull the hills at such low engine speeds? With 1,860 lb-ft of torque, and with no more speed loss than one would find with higher revving engines.

Transmission Trends

Most automated manual transmissions go into highway tractors, but Eaton offers three vocational versions of the UltraShift Plus for on/off-road trucks such as dumps and mixers.

By Tom Berg

The swing continues toward heavy automated products, but manuals still dominate. Light and medium trucks are almost all ‘shiftless.’

Test Drive: Detroit’s Smooth Self-Shifter

This Freightliner Cascadia Evolution is equipped with a Detroit DD13 diesel and smooth DT12 automated mechanical transmission. The van shown here was empty, so we swapped it out  for a heavily loaded flatbed trailer for our evaluation.

By Tom Berg

“Proprietary” is a magic word among truck builders. It describes components of the company’s own manufacture or design that are installed on the company’s own trucks. For truck users, this can be a good thing, because they’re designed to work specifically with a company’s other components.

Stay Ahead of Trouble on EGR Engines

EGR valves live in a very hostile environment.

By Jim Park

While most of the early problems have been engineered out of the exhaust gas recirculation systems on today’s clean diesel engines, corroded coolers, stuck valves and other problems still plague owners of older equipment.

Save Fuel, Increase Profit, Save the Planet

By Tom Berg

Class 8 Update: Economics Forge Change

Western Star:The flagship from Western Star, a Daimler Trucks brand, is the 4900 with 132-inch cab and hood and long sleeper that’s built for the highway but looks good in town. It and the shorter 4800 are also equipped for vocational work with forward and setback steer axles or twin-steer configurations. Just announced is a 4800SB 8x8 whose setback, driving steer axle is paired with Meritor tri-drive rear axles.

By Tom Berg

Is trucking in for a transformation? Many believe that long-haul trucking will become less important as regional operations grow and intermodal takes over more long-haul freight, and that will change the type of heavy-duty tractor bought by many trucking companies.

Test Drive: Single-Rear-Axle Granite MHD

The single rear axle allows Class 7 ratings, but this one’s decidedly Class 8, with axles totaling 44,000 pounds in capacity. The steer axle is set forward to better handle weight of the plow mount and, when it snows, a long steel blade.

By Tom Berg

Is this single-rear-axle truck the type of medium-heavy-duty model that Mack should have brought out first? I asked that question two years ago when I saw the initial offering, the tandem-axle Granite MHD. I figured other than the tandem, it was just right for municipal fleets and others who don’t need high carrying capacity.

DME: An Alternative Fuel that is Coming Soon

This DME engine is based on a Volvo D13 diesel. This prototype has common-rail fuel injection, which the production engine might or might not use.

By Tom Berg

Volvo Trucks North America believes dimethyl ether, or DME, is the real fuel of the future, and the company intends to get it to market as a motor fuel by 2015 in Volvo VN models as well as Mack Pinnacle trucks from its sister company.

Brakes: Shorter Stopping Distances, Again

Tractors with gross-weight ratings of over 59,600 pounds, like this heavy haul model, are among those affected by FMVSS 121’s requirements for shorter stopping distances.

By Tom Berg

Coming up: another “non-event” for brakes? That’s what Phase Two of new federal stopping-distance requirements will be for truck operators, according to people we talked with. Stronger, higher-performance brakes on certain vehicles won’t even cost much more in most cases. But like Phase One two years ago, which was hardly noticed by truckers, Phase Two represents a lot of work for brake makers and truck builders.

Transmissions: Automating for Fuel Savings

Drivers still have some control over automated manual transmissions, but the equipment will usually do a better job of improving fuel economy if it’s simply left alone.

By Jim Park

Traditional thinking on automated manual transmissions has it that AMTs are the great equalizers – bridgers of skill gaps between the best and the worst drivers in the fleet. While that’s still true, AMTs now bring even more to the fuel-economy table, offering fuel savings in their own right beyond what even the most professionally driven manual transmission could accomplish.
