Innovations shape our world, every day in many ways, and the staff at Heavy Equipment Guide want to acknowledge their importance in the world of construction-related equipment. As a result, we have created this new annual feature. Our goal is to illustrate the range and scope of advances, from earthmoving to paving, aggregates, lift, maintenance, training, wearables and others. These innovations offer advantages from doing the job faster, more accurately, more safely, more comfortably or more efficiently, to improving maintenance or providing a better ROI. The editors' selections are drawn from our coverage during the year. The selection was not always easy as there are many worthy innovations but we hope the diversity of the ones shown provide an appreciation of the vast amounts of time and money which manufacturers spend developing innovations, large and small, that make our lives better.
The Wirtgen Group showed of a number of its latest innovations at Intermat this year, all 5 brands were strongly represented: Wirtgen, Vögele, Hamm, Kleemann and Benninghoven. Visitors had the chance to talk with experienced applications experts from the Group and got up to speed on the latest technologies for the entire road construction cycle while learning more about the Wirtgen Group's extensive range of service offerings. Here is an overview of some of the highlights:
W 150 CFi with 1800-mm milling drum assembly leads the Wirtgen line-up.
World of Asphalt will be held in Houston, Texas, from March 6 to 8 and features educational programming and exhibits focusing on the latest technology and innovations for the asphalt industry. The Agg1 Aggregates Academy & Expo, co-located with World of Asphalt, offers educational sessions and exhibits on the latest developments for the aggregates industry. The following are highlights of products that attendees can expect to see at the shows.
Hamm is introducing its new DV+ series tandem rollers to North America at CONEXPO-CON/AGG 2017. For the launch in Las Vegas, Hamm is showing a DV+ 70i model weighing 7.7 tons (7 metric tonnes). Other models are set to follow in 2018. These highly productive, pivot-steered rollers meet all requirements for optimum compaction quality. According to Hamm, operators are enthusiastic about the excellent visibility and the new, intuitive Easy Drive operating concept.
Modern construction machines are high-tech units whose engineering enables more functions to be carried out than ever before. Whether these are recognized and used by operators is crucially dependent on the quality of the operating concept. So that the operators of Hamm rollers can use all the functions to their full extent, the development team attached the utmost importance to simple, intuitive operation. No easy task, since the modern rollers are complex tools. With the new Easy Drive operating concept, Hamm has succeeded in pulling off this balancing act. It enables drivers to respond quickly and correctly, even without extensive previous knowledge. This is made possible through a minimal number of intelligently arranged switches, good visibility in the operator’s platform and short learning and familiarization times.
Hamm displayed a prototype of a hybrid powertrain for the HD+ 90i tandem roller at Bauma. The innovative concept has been developed to save fuel costs and maintenance effort. This new development combines the traditional internal combustion engine with a hydraulic accumulator. The internal combustion engine covers the base load while a hydraulic accumulator meets peak loads.
For Bauma 2016, HAMM is displaying its VC compactors, which are now ready for series production. These compactors with a VC crusher drum carry out two tasks simultaneously: they crush rock and compact it at the same time. Three years ago, the series prototype attracted a great deal of attention at bauma. In the meantime, HAMM has subjected the VC crusher drums to intensive testing in different applications in the course of many tough assignments, refined the machine concept and developed the VC machines to become genuine heavy-duty units.
