Benninghoven will present the new ECO system concept for the first time at the show

More than 100 Ammann products will be on display at the show, including many new offerings. Ammann will also mark its 150th anniversary at Bauma 2019.

Among the products and services that will be showcased will be light equipment, specifically a new line of APH Hydrostatic Vibratory Plate Compactors, which will replace the current line of machines. Key features include ACE technology for advanced compaction and the triple-shaft exciter system, which keeps plate movement consistent and enables smooth travel. The new line of APR Reversible Vibratory Plate Compactors will also be presented.

Regarding compaction machines, the ARX 91 Articulated Tandem Roller, which utilises high compaction output, will be at the show. The output is provided through a combination of drum dimensions, frequencies and amplitudes.

The ART 280 Hydrostatic Tyred Roller is available with engines that meet varied emissions levels. Ammann’s modular, easy-load ballasting system enables the machine weight to be adjusted from 9 tonnes to 28 tonnes in a single hour with the help of only a forklift.

The new series of ARX Light Tandem Rollers are said to make it even easier for operators to work next to obstructions such as curbs.

The ARS 122 T3 Soil Compactor incorporates a Cummins BS-III engine, equivalent to a Tier 3. The ARS line features Ammann’s no-rear-axle concept.

The ARP 95 ST5 Pivot-Steer Roller has a redesigned main frame that enables the machine to work as wide as 3070 mm when in an offset configuration. It is the widest working width of a roller of its size on the market.

Concrete and asphalt products will also be on display. These include the ABC ValueTec Asphalt-Mixing Plants, the transport-optimised CBT 130 TB Elba Concrete-Mixing Plant and the RSS 120-M Shredder, Iron Separator and Screen, a mobile machine that prepares recycled asphalt for use in an asphalt-mixing plant.

Benninghoven will present the new ECO system concept for the first time. The type ECO asphalt mixing plant in capacity sizes from 100-320 t/h combines state-of-the-art technologies and a high standard of manufacturing in compact container sizes. This is said to ensure maximum mobility and flexibility. Type ECO systems can be operated as stationary systems, but can also handle rapid location changes.

The modular design of the ECO series also allows various high-tech components to be integrated afterwards. In this way, operating companies can react to future customer and market requirements – particularly for asphalt recycling.

The flexibility of the ECO series is down to its systematic approach – these asphalt mixing plants are transportable and have a container design. All of the main components are designed for simple transportation in standard container dimensions. This type of plant can produce up to 320 t/h of asphalt, sufficient for supplying the road pavers with a constant flow of material – even in major projects such as motorway construction.

The strength of the plants is their ability to be transported worldwide and that they can be designed as simply, cost-efficiently and effectively as possible.


Bomag’s new BW 174 AP tandem roller with a hydraulic hybrid drive system will be available from April 2019

At booth FS 1009, Bomag will be presenting a number of new innovations for the roadbuilding sector.

One machine on display will be the new BW 174 AP tandem roller with a hydraulic hybrid drive system, which will be available from April 2019. It combines a diesel engine with a hydraulic accumulator and Bomag’s Asphalt Manager.

Delivering 100Nm and 20kW of power to the crankshaft, the hydraulic hybrid accumulator makes it possible to use a more compact motor. Overall, the hybrid solution was said to reduce CO2 emissions by up to 20%.

Bomag will also be demonstrating three different drive solutions for the future, in view of increasingly stringent emissions regulations. The BW 120 light tandem roller will be used as an example to show the different systems.

The new BM 500/15 and BM 600/15 cold planers will be launched at Bauma. Both models are equipped with a 105kW diesel drive that meets EU Stage V emissions standards, and offer a milling depth of up to 210mm.

One particular highlight of these second-generation models is said to be the redesigned workspace. The entire platform is isolated from oscillation and is therefore free from stressful vibrations. All machine functions are accessible from the seat, which can be swivelled by 45°.

The milling process produces large quantities of potentially hazardous fine dust, so to combat this Bomag will be presenting its Ion Dust Shield technology for cold milling machines.

Cat AP555E

Caterpillar’s AP555E

One of the road building pieces of equipment that Caterpillar will be showing is the AP555F, a mid-sized, rubber track paver that is said to excel on highways, streets and other urban work sites.

The AP555F features advanced control technology and quick-heating SE50 VT electric screeds that boost productivity of the machine and crew. It features the exclusive Cat Mobil-Trac rubber track undercarriage, which is said to deliver high travel speed, excellent flotation, superior traction and mobility.

The machine is powered with a Cat C4.4 ACERT engine that provides 142 horsepower (106 kW). A standard Eco-Mode setting, when used with automatic engine-speed control, manages engine speed for optimum fuel economy and reduced sound.

The vibratory soil compactor is represented by Cat models CS12 GC, CS44B, and CS66B. All three models can be equipped with Cat Compaction Control, which provides compaction measurement technology and can also provide satellite mapping.

Al PM310 cold planer will also be on display. PM 300-Series models are designed for small-to-medium job sites and feature three drum sizes, wheel or track undercarriages, and articulating right-rear leg for right-side flush cutting. Features include advanced controls and system integration.


Gomaco’s GP4 slipform paver will make its international exhibition debut at Bauma

GOMACO will showcase their zero-turn capable pavers in the outdoor area FS, on stand 1210/3.

Contractors around the world face the same job-site challenges, from short runs, tight radius and corners in parking lots, to a multitude of obstacles to pave around. GOMACO’s Xtreme curb and gutter machines are said to be able to handle these challenges and can also slipform a 610mm radius or less.

The new Xtreme three-track Commander IIIx and two GOMACO 3300s with the GOMACO G+ control system will be on display.  These machines feature rotary-sensored slew drives on the tracks, sensored leg positioning, and independent travel circuits to each track to allow tight radius slipforming. Intelligent All-Track Positioning is accomplished with smart hydraulic cylinders on the three legs which allows G+ to know the position of the tracks at all times.

The Commander IIIx and 3300 feature Tier 4 engines and optimised cooling packages with G+ controlling the hydraulic fan.

Zero-turn capabilities are also incorporated into large pavers, such as the new GP4 slipform paver, capable of paving widths up to 12.2m – the machine will make its international exhibition debut at Bauma.

The GOMACO GP-2400 is the company’s smaller, economical slipform paver capable of slipforming widths up to 7.4m, with 2m of telescoping ability on the left side. Its smaller size makes it a popular paver on projects across the world.

Completing the display will be the Curb Cadet, a mobile and compact curb machine. The Curb Cadet slipforms concrete curb or extrudes asphalt curb from either side of the machine.


Perfect for compacting challenging surfaces ad curved sections: Hamm’s patented, split oscillation drum

Hamm is presenting innovations in all product segments, including a few world premieres. The spectrum ranges from a completely new series of pneumatic tyre rollers and the first tandem roller with true split oscillation drums to numerous new options for earthwork compaction.

The HP series of pneumatic tyre rollers is one of the world premieres. HP series rollers are said to offer drivers simple, intuitive operation and an ergonomically optimised operator’s platform. Together with a number of sophisticated details in terms of machine design, the asymmetrical frame provides for excellent compaction and optimal visibility.

The HP series pneumatic tyre rollers will be available in various basic versions (HP 180 / HP 180i and HP 280 / HP 280i) with operating weights ranging from 8-28 tonnes. Hamm will supply the models worldwide in accordance with the locally demanded weight classes and equipment variants – taking into account local emissions regulations.

Hamm is also presenting a split oscillation drum and the VIO compaction meter for oscillation. The company says they have also further optimised the drive concept for the oscillation drums, making the next generation of oscillation drums completely maintenance-free.

Hamm now also offers split oscillation drums, which combine the benefits of oscillation with the added value of a split drum. Oscillation enables these drums to deliver excellent results for compaction on bridges, of thin layers, in vibration-sensitive areas or at critical temperatures.


Mecalac’s TV1200 has a new driving system

Mecalac will launch the TV1200, a tandem vibration compaction roller with a new driving system.

Most tandem rollers are manoeuvred using the wheel on the steering column. The presence of this steering column forces the driver to contort himself just to get into the seat. Once in position, he drives with one hand on the wheel, the other on the lever, all while keeping an eye on the trajectory of the front drum. Fatigue, musculoskeletal problems and risks of falling when climbing on or off are problems inherent to this traditional design.

Mecalac have looked to improve access and the driving position for effectiveness, safety and comfort.

The TV1200 tandem vibrating compaction roller has been shortlisted for the Bauma Innovation Award in the design category.


Vogele’s Super 3003i

Vögele will launch several premiers: the Super 3000-3i, the biggest paver in the company’s product range, the Super 1000i and 1003i compact pavers, the SB 300 and SB 350 Fixed-Width Screeds, and the new functions of the WITOS Paving process-management solution.

To help customers find their way around the large range of different pavers, Vögele restructured their product range at the end of last year, dividing it into two lines: the Classic Line and the Premium Line. Within the lines, the company again differentiates between the previous five classes of Mini, Compact, Universal, Highway and Special Class.

The latest and representative of the Premium Line is the Super 3000-3i. With a pave width of up to 18m, a laydown rate of 1,800t/h and an engine output of 354kW, it is the new flagship in Vögele’s paver line-up. It is not only suitable for medium-sized construction projects and the rehabilitation and construction of motorways, but also for paving airport runways, large squares and traffic areas.

Vögele will also be presenting two highlights from their screed programme, the new SB 300 and SB 350 Fixed-Width Screeds and four new products from their Classic Line: the super 1000i in the tracked version and the super 1003i in the wheeled version, as well as the super 1600 and super 1603.

Volvo CE will be showing the P2820D ABG and P2870D

ABG, the most compact pavers in the Volvo line-up. They are said to be the perfect partners for small-to-medium paving applications, offering low operating cost, safety and operator comfort.

The P2820D ABG and P2870D ABG generate low levels of noise, making them suited to inner-city projects. The new machines also promise low fuel consumption and low CO2 emissions. With their 55kW Volvo engines and matched hydraulics, the compact pavers feature the same drive system fitted to larger models.

Wacker Neuson will be showing a broad portfolio of battery-powered rammers and vibratory plates, such as the AS60e battery-powered rammer and the AP2560e battery-powered vibratory plate. Both machines are equipped with Wacker Neuson’s proven battery.

“Emissions are set to become an increasingly problematic issue, especially in urban areas. With our zero emission solutions, our customers will definitely be on the safe side. In meeting emission mitigation needs, we also make sure that we only launch a product once we know that it can do an average day’s work on a single battery charge and that the equipment will pay for itself in three years or less,” said Alexander Greschner, CSO of the Wacker Neuson Group.

Wirtgen said it would be presenting world premieres and innovations in all of its product segments.

The Wirtgen brand itself has developed the W 380 CRi cold recycler, which will be unveiled to the world at Bauma.

With available working widths of 3,200, 3,500 and 3,800mm, the recycler mills the road between 100 and 300mm deep in most applications. At the same time, it granulates the material and transforms it into a new, homogeneous material mixture by adding binding agents such as cement, bitumen emulsion, or foamed bitumen.

With a mixing capacity of up to 800 tonnes/h, the cold recycler can feed enormous quantities of recycled material to a Vögele paver via its swivel-mounted and height-adjustable discharge conveyor at the rear. It said this made it possible to complete extremely long stretches of road in a single day of work. iC
