1) Daimler Trucks launches autonomous technology

Germany-based Daimler Trucks has announced its latest development: the Highway Pilot Connect system, which autonomously drives heavy trucks. Last month, the company displayed three WiFi-connected, autonomously driving trucks on the A52 autobahn near Düsseldorf, Germany, said a statement from the company.
 
Based on the Daimler Trucks Highway Pilot system for autonomously driving heavy trucks, the three trucks linked up to form an aerodynamically optimized, fully automated platoon, it added.
 
The completely connected truck initiates a radical change in transport which will make traffic even more effective and efficient – not only for drivers, haulers and vehicle manufacturers, but also for society as a whole. The combination can reduce fuel consumption by up to 7 per cent and the road space requirement on motorways by almost half - while improving traffic safety at the same time, it said.
 
Dr Wolfgang Bernhard, member of the board of management of Daimler AG, with responsibility for Daimler Trucks and Buses, said: “We are creating a new, highly efficient and open logistical network.”
 
“We are connecting the truck with the internet – making it the main data node of the logistics network. It connects all those involved in goods: drivers, schedulers, fleet operators, workshops, manufacturers and insurance companies or authorities. They receive information in real time which was previously unavailable: about the condition of the tractor unit and semitrailer, traffic and weather conditions, the parking availability at motorway service stations, rest areas and much more,” he said.
 
 
2) Case big skid steer pays off on small details 

Case Construction Equipment has been indelibly linked with two products over the years—backhoe-loaders and skid steer loaders. It invented the first factory-integrated backhoe-loader in 1957, and was an early skid steer competitor for Bobcat (Melroe), after purchasing the Uni-Loader brand in 1969.

The Case skid steer pedigree has been somewhat uneven, however. After years of producing the “1800 Series,” which included the bulletproof 1845C, a unit still seen on job sites today, Case skid steers were given several new identities. Each hoped to improve on what came before, but the 1800s proved a difficult act to follow.

There were the XTs in 1997, the 400 Series in 2005, and the Alpha Series, beginning in 2014.

The advent of the Alpha Series marked the fourth different name for the product offering in a span of 18 years. It can be a red flag when a manufacturer continually renames a family of machines, but recent times have seen renewed stability and additional investment in the iron.

The 90-horsepower SR270 is the largest radial-lift unit in the nine Case skid steer models comprising the Alpha Series, noteworthy for being the first set of skid steers in the industry to use SCR technology to address Tier 4-Final emissions guidelines.

While other manufacturers and a number of engine makers postured against SCR and spent their marketing dollars to back EGR technology, Case was a bold early adopter of SCR among construction OEMs, leveraging CNH Industrial’s Fiat Powertrain (FPT) worldwide experience with SCR in on-road and agricultural applications.


3) Caterpillar’s new 308E2 excavator with variable angle boom lets you work really close to the tracks and blade

Thanks to a variable angle boom design, Caterpillar’s new 308E2 VAB is more capable when digging near and away from the tracks.

“The VAB design is hugely popular in Europe and Germany,” says Cat’s Greg Worley. “The standard 308’s boom has a fixed arch, but with this design you can straighten that arch all the way out or pull it very close in confined areas.”

That one extra articulation point has some big effects. Reach is extended by 30 inches to 306 in., while dump clearance is extended by 56 to 239 in. That reach can be extended even further with the optional long stick.

And those who use an 8-ton excavator in tunneling and tree management applications will be interested in the added 54 in. of maximum working height, to a total of 315 in. And while the extended reach is certainly impressive, the added versatility of the design is especially apparent when working close to the tracks.

At a recent press event, Cat invited media members to operate the machine atop a small raised pad. The design allows for folding the boom extremely close to the cab (compressing overhang to only 11 inches) with all VAB functionality being controlled from a foot pedal.

The machine not only increases lifting capacity in confined spaces, but also makes moving dirt between the bucket and blade much easier, demonstrating added productivity in applications such as digging on urban jobsites or mowing along busy highways.

The 308E2 VAB features load-sensing hydraulics deliver flows of 39.6 gallons per minute and is powered by a 65-horsepower Cat C3.3B engine. The machine weighs in at 19,184 pounds. 

 
4) Volvo unveils the DD105: New compactor design boasts faster eccentric, better visibility, available cab

Volvo Construction Equipment has unveiled a double-drum compactor featuring a completely new design the company says will be its way forward in this segment. The new DD105 is a 10-ton large asphalt compactor with a 66-inch wide drum. The machine will replace the DD110B and gains a new 3.8-liter Volvo Tier 4 Final engine, improved fuel economy, better visibility and a new pedestal design that makes it the first compactor Volvo will offer with an enclosed cab in North America.

Another major development for this machine is the new eccentric system, which has made near-instantaneous spin-up possible.

The new engine produces 114 horsepower and the machine weighs in at just over 22,000 pounds. The machine’s ECO mode has amounted to increased fuel economy of up to 30 percent in Volvo’s testing. In real world terms, that’s as much as two gallons saved per hour.
