International LT Launched Loudly, Described Enthusiastically

Navistar unveiled its new International LT series in Las Vegas on Sept. 30 with speeches, videos, hard rock music, and fire-and-smoke effects – a launch befitting a "Vegas" production and a vehicle range that will become the company's flagship model and, executives hope, the most popular highway tractor on the market.

At the event at the World Market Center, dealers and customers applauded and some trade press reporters nodded approvingly as three tractors drove onto a platform from which top executives had previously spoken. All emphasized the customer research and meticulous design and engineering work that had gone into the new model. It will begin replacing the nine-year-old ProStar series when it enters production in November.

The initial version has Cummins power, and several Navistar execs remarked that their company's strong relationship with Cummins will continue, notwithstanding the recently announced alliance with Volkswagen Truck & Bus of Germany.

The Internationl LT (for Linehaul Transport) was publicly announced Friday morning. It is the first model that stems from Navistar's Project Horizon, a three-year effort to update and improve the ProStar. Horizon affects steel-cab models, and the WorkStar and DuraStar trucks are now being worked on for introduction in 2017.

The HX premium vocational truck, introduced eight months ago and now in production, uses an aluminum cab, so was not part of Horizon.

During development, several Navistar executives rode with fleet drivers to learn what they want in a highway tractor. Drivers' comments and the execs' experiences were chronicled in a video. Those drivers -- Kenneth Stiltner of Cowan Systems, Jose Reyes of Mesilla Valley Transportation and David Spore of J.B. Hunt -- were present at the launch in Las Vegas.

Jost Shows New Trailer Developments at IAA 2016

The Jost Group introduced a new fifth wheel coupling and trailer steering system at the IAA Commercial Vehicle Show in Hannover, Germany.

The JSK 34 sensor coupling version of the ultralight JSK 34 fifth wheel coupling was shown at the show. The ultralight JSK 34 cast fifth-wheel coupling is designed for 2-inch kingpins and can reduce the system weight by up to 88 pounds in some series. It is suitable for all weight-sensitive transports, such as tanker and silo transports.

Jost has equipped the JSK 34 with a hybrid bearing to increase driving comfort and service life while also reducing the dynamic load on the vehicle's frame. This type of bearing combines the robustness and shock absorbing performance of a rubber bearing with the frame-friendly properties of a plastic bearing.

Tridec, Jost's brand for trailer axle steering systems and single-wheel suspensions, presented the EF-S steering system for trailers, which provides more options for driving, maneuvering and safety with its sensor technology and remote control.

EF-S enables trailers with an extremely low trailer neck, such as milk and bulk tankers or trailers with monocoque constructions, to be equipped with a steering system for kingpin axles. The kingpin steering system can steer a maximum of three kingpin-steered axles. It allows the trailer to turn more than usual in tight bends or minimize the swing-out radius of the rear in confined space conditions.

Manual steering by wireless remote control makes the axles steer in ratio or at equal steering angles (“crab steering”). EF-S can deliver extra maneuverability leading to time savings, lower fuel consumption and less tire wear. The EF-S steering system is designed to be simple and easy to install without enormous adapting to the frame, allowing the steering angle to adapt to the mounting space.

ZF Emphasizes Safety with Newest Innovation Concept Truck

ZF rolled out its Innovation Truck 2016 concept vehicle at the IAA show in Hannover, Germany, to demonstrate its capabilities for developing autonomous-driving technologies.

Noting that it is keeping at the forefront its “Vison Zero” goal of attaining accident-free driving, the Germany-based component supplier said it's “working on enhancing current assist systems for practical use on the road.”

The company said those efforts have led to developing a Highway Driving Assist (HDA) that helps to keep the vehicle in its lane and an Evasive Maneuver Assist (EMA) system that allows a truck to independently evade obstacles and brake. ZF noted that EMA was developed in cooperation with Wabco.

ZF said its Innovation Truck 2016 also “boasts a highly efficient solution with its autonomous maneuvering function,” dubbed SafeRange. “Its intelligently networked systems allow the concept vehicle to autonomously maneuver to the loading bay in a precise and efficient manner, and if needed, with zero local emissions,” the company stated.

By applying its expertise in sensor technology, control electronics and mechatronic systems, ZF said it has enabled the Innovation Truck 2016 “to see, think and act” for safer and more efficient driving.

According to ZF, here is how each of the three new systems function:

Daimler and trailer maker partner on European fuel-efficient rig

Daimler's Mercedes-Benz Truck unit along with Germany-based trailer maker Krone have teamed up to put together a linehaul tractor-trailer they say delivers up to a 20% cut in fuel consumption compared to existing combinations.

The rig, rolled out at the IAA Truck Show in Frankfurt, Germany, consists of the latest generation Mercedes-Benz Actros over-the-road cabover mated to Krone's new Profi Liner Efficiency, an aerodynamically enhanced curtain-side trailer fitted with low-rolling-resistance tires.

According to Daimler, the specific Mercedes-Benz Actros unveiled at IAA features an efficiency package that includes the latest generation OM 471 six-cylinder in-line diesel engine as well as the OEM's Predictive Powertrain Control (described as an “anticipatory cruise control system”) and “A-label” low-rolling-resistance tires.

When combined with the new Krone Profi Liner Efficiency trailer, Daimler said “it promises a reduction in fuel consumption, and therefore CO2 emissions, of up to 20% compared to existing combinations.” A standard semitrailer-tractor combination from 2014 is the basis of the comparison. The manufacturers said that their second yearly “Efficiency Run” involved five fleet customers that tested the fuel efficiency of the rigs and verified the results.

Daimler and Krone laid out the various contributions that added up to the 20% efficiency gain:

The trailer's aerodynamics were improved with new self-engineered Krone side panels made of impact-resistant plastic that cover all the sides, including those of the three trailer axles and a four-part folding “rear wing,” also made of robust plastic.

"In 2015, the first Efficiency ...Read the rest of this story
