Cummins has taken a major leap forward with engine design as it ditches cooled exhaust gas recirculation for its newest heavy-duty six-cylinder engine platform launched at bauma – the 12-litre QSM12. As its Tier 4 Final/Stage 4 engine solution in the 250-383kW sector, the QSM12 benefits from higher efficiency air handling and an advanced in-cylinder combustion process, allowing a return to using a straightforward wastegated turbocharger.

Rammer, the hydraulic breaker division of Sandvik Construction, has added four additional hammers to its line-up. There are three new models for the compact range – the 255, 355 and 455 – plus the 5011 model joins the heavy breaker line. The small range models are suitable for 1.2-5.2tonne carriers. They all feature Rammer’s constant blow energy (CBE) operating design that ensures constant impact energy for every blow. The 5011 is designed for use with carrier machines in the 43-80tonne class, slotting into

CNH Construction marketing director Jean-Patrick Yekpe has highlighted the money-saving potential of Case Construction Equipment’s new midi-excavators, unveiled at bauma 2013. The Tier 4 Final requirements of the CX75C SR and CX80C have been met, says Yekpe, through the use of cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst system. “When the soot is coming out of the engine as smoke and touches the platinum inside the engine you get an oxidation, and as a consequence of thi

The six bauma Innovation Award 2013 winners have been revealed. Pipe Express, from Herrenknecht, triumphed in the Machinery category, while AutoPilot Field Rover, from Wirtgen, took the Machine Components section. The Construction process/Construction work category had two winners.

Bell has introduced a 4x4 version of its B30D articulated dump truck (ADT). The machine has the front chassis, cab and engine of the standard 6x6 but comes with a shortened rear chassis and a single axle. According to Neville Paynter, managing director of Bell UK, the machine’s short wheelbase reduces the turning circle by around 25%, making it ideal for use in underground mining and on narrow benches.

JCB says its Ecomax Stage 4/Tier 4 Final engine can be engineered into many existing machines without needing additional space by using a ‘one can’ selective catalytic reduction (SCR). According to the company’s chief technology officer, Tim Burnhope, in many cases the mini SCR on the Stage 4/Tier 4 Final Ecomax engine can be positioned in the same space occupied by the exhaust silencer on previous generations. He said, “Our engine is already so clean that we only need 2% to 3% of urea, which allows us to u

Skako Concrete has – literally – unveiled its new Rotoconix mixer after keeping the new model under cover until 11am on the first day of bauma. The Rotoconix is designed for quick batching cycles, fast discharge and uniform mixing no matter the batch size. The mixer has three key parts, all of which are reversible. It combines a rotating cone a high-speed ‘turbo whirler’ and a screw.

From mixing plant to compaction, the temperature of asphalt is critical. Cold asphalt can lead to road damages, which result in additional costs of up to 46% due a shorter lifetime of the road. With optimum composition of both asphalt material and process flow being priorities in the road construction process, the new MOBA PAVE-IR temperature scanner system enhances both.

After two years of research and development, attachment manufacturer Simex has launched the VSE 40, a screening bucket with a patented mechanism that allows the operator to change the size of the screened material from the cab at the touch of a button. All similar products require eight to 10 hours’ work to change the setting, according to Simex’s assistant general manager Fereico Tamburri. “After we introduced our crushing bucket, we visited lots of crushing sites and found out that for all the screening b

Three-dimensional technology is playing an increasingly important role on construction sites around the world but there are still projects for which there is no 3D data and the use of a 2D system makes more sense for machine control. With the new 3D-matic, MOBA offers a precise and flexible 3D levelling system for graders, dozers and blades that can also be used as a 2D system if necessary. MOBA 3D-matic increases efficiency in machine use and contributes to fast and precise project execution. The compact t

SKF Insight features intelligent wireless technology that enables bearings to communicate their operating conditions continuously, with internally powered sensors and data acquisition electronics. Bearings have long been considered the heart of rotating machinery but now SKF has made them the brain as well.

LiuGong and its partners – Cummins and ZF – chose bauma 2013 to celebrate a string of successes with joint ventures, shared factories, and profitable partnerships. “We looked for only the best partners that share our commitment to excellence,” said Zeng Guang’an, LiuGong’s vice chairman and president. “With Cummins and ZF we believe we have found two of the best.” LiuGong’s joint venture with ZF began in 1995, which allowed the Chinese maker to cost-effectively incorporate high-level ZF technology into its

A senior LiuGong figure has revealed that the Chinese construction manufacturing giant is looking to double its US$700million overseas sales for 2012 in the next three years. Speaking at bauma 2013 Zeng Guang’an, the company’s vice chairman and president, explained how the ambitious international sales target was getting closer to being realised.

Comer Industries is using bauma to introduce its next generation of axles, wheel drives and heavy-duty track drives. Products on display at bauma include the series of new-generation axles starting from S-228, developed to provide high braking and efficient performance. The S-228-238 line was designed and built for applications including earthmoving. On display at bauma is the S-238, which has a dynamic load capacity of 12,000daN and a static load capacity of 22,000daN.

Sandvik has unveiled the Premium QI441 PriSec Impactor mobile crusher and the QE341 mobile scalper, both of which have been designed with improved output, easier operation and increased mobility. The QI441 features Sandvik’s patented PriSec crushing chamber, which is designed for rapid switching between primary and secondary crushing applications. Two hydraulically adjusted curtains permit the production of a wide range of product sizes. Increased discharge heights and conveyor lengths deliver up to 50% mor
