Europe: Bauma trade fair pre-view: Part 2

baumaBauma, Europe’s largest trade fair for construction machinery, takes place in Munich, Germany, from April 11 – 17.

We preview, in this second part, some of the highlights at the 31 show which has 3,421 exhibitors from 57 countries and attracts over half a million trade visitors, 125,850 from the mining sector alone.

Here we feature a tiny taste of the new products. There’s more in Part 1.

Liebherr advanced loader models
Liebherr says its new wheeled loader range will offer high operating efficiency. High performance with fast cycle times are said to be matched with precise control at low speeds as well as low fuel consumption and running costs. Durable and reliable, the machines are said to be heavily built to cope with tough site conditions.

The most innovative feature of Liebherr machines is the new driveline system that combines Liebherr’s hydrostatic system with a mechanical drive developed by ZF

The most innovative feature of the machines is the new driveline system, which combines Liebherr’s trademark hydrostatic system with a mechanical drive developed by ZF. According to Liebherr this will make the new loaders more fuel efficient than any other models available.

The hydrostatic drive works for forward and reverse and at low speeds where precision is required. At full speed for longer load and carry cycles, the machines switch over completely to the constantly variable transmission (CVT) mechanical drive. When operating at speeds in between, the onboard electronics govern precisely how much of the drive is through the hydrostatic and CVT systems. This is monitored and balanced continuously to optimise performance, boosting efficiency.

The low emission engines are also Liebherr units and have no need of EGR systems. This is said to reduce cooling requirements and also boost operating safety in applications where the heat generated by an EGR system poses a potential risk.

Customers can select either z-bar linkages or parallel (industrial) linkages to suit the application and at no extra cost. A range of bucket options is also available. With the engines mounted behind the back axle, weight distribution is also said to be optimised for loading operations. Other benefits include advanced cooling systems, improved operator comfort and visibility and easy maintenance procedures.

Bell E Series line-up completed
Bell Equipment is expanding its E Series articulated hauler line-up with the introduction of the B45E, offering a rated payload of 41tonnes. Powered by the latest six-cylinder Mercedes-Benz off-highway diesel engines and driving through Allison transmissions, Bell’s large truck range all benefit from increased payloads and the company promises a 6-7% lower cost per tonne for the E Series models when compared with previous D series trucks.

To accommodate the larger 7-speed transmission, Bell has removed the automatic retarder on the transmission and opted to incorporate this feature into the wet brake system. The trucks have also adopted a Jacobs engine brake.

“The retardation is still operated automatically and the new position of the retardation will not adversely impact on brake life. This is because extensive testing has shown that at the low pressures generated in the brakes during retardation there is always oil between the wet brake plates, so there is no touching and wear,” said product marketing manager Tristan du Pisanie.

“The retardation power of the Jacobs engine brake is higher than the engine braking produced by the outgoing V6 and V8 engines on the D-series trucks. The benefit is that a lot less retardation outside of the engine is required,” said du Pisanie.

Ammann versatile asphalt plants
Ammann says that its QuickBatch plant has been transport-optimised to make it more mobile and versatile. The new QuickBatch plant is designed for easy, cost-effective transportation and installation. The plant fits into a series of standard shipping containers, making it easy to move from one site to another. In conventional layout it can be carried in nine containers, though additional features may require more units. Typical additions include special equipment for handling RAP and using this in asphalt production. However the firm says that this system also offers customers the benefits of more conventional stationary facilities, such as a high-production capacity. Key core components, including dryer/filter units and mixing tower modules are all fitted inside standard transport containers.

Keestrack new track-mounted H4 cone crusher
Keestrack says its new track-mounted cone crusher H4 as the first of its kind in the world.  At the heart of the model, designed for high-value secondary or tertiary production in the 120-200tonnes/hour performance range, is the proven cone crushing technology of a world-renowned supply partner, with whom the company is working closely to optimise its machines for deployment in mobile situations.

According to Keestrack, a pioneering factor has been the advanced solutions in crusher control and monitoring systems, directly impacting output capacity and product quality. As the successor to the Galleon series, the Keestrack H4, which has a transport weight of 35-50tonnes, has been given a completely new frame design, enabling the incorporation of efficient pre and post-screening units but also the use of innovative drive technologies.

For example, the Keestrack says the H4 is the world’s first mobile cone crusher with a three-deck post-screening module with an oversize material recycler for the production of three high-grade end products in one pass.

Keestrack is offering a choice of three economical drive combinations: direct diesel drive of the crusher with electrical or electro-hydraulic peripherals, such as conveyors and screen units, or the fully hybrid/plug-in version with similar electrical crusher drive via on-board diesel generator or mains power.

High productivity is claimed by Atlas Copco Dynapac for its new medium class pavers, the SD1800 Citypaver. The machine offers a capacity of 350tonnes/hour and can be used for paving widths from 0.7-4.7m, suiting it to use in urban road construction and repair work. The new machine benefits from the firm’s sophisticated PaveManager 2.0 system, which is well proven in the company’s large SD pavers.

Equipped with electro-hydraulic controls, the machine is powered by an emissions compliant Deutz diesel delivering 54kW. This supplies its power through an efficient system that minimises losses and optimises efficiency, lowering fuel consumption. The machine has the intelligent PaveManager 2.0 control system that offers accurate paving control for all applications. This optimises performance and is directly connected through a CAN BUS system. This assures fast and reliable communication and also recognises all levelling equipment from Moba.

With its compact 5m length 1.8m width, the SD1800 can work in narrow job sites while its low height of the paver allows it to work in covered parking areas or below trees. Other advantages include its ergonomic platform with pivotable and slidable seats as well as a control panel that is slidable and tiltable.

The screeds feature proven designs from the firm’s large-pavers. The V3500 is said to be stable due to its robust dual-tube extension system. The new screed range is available with vibration only or tamping and vibration pre-compaction systems, while heating can be electric or gas.

Hitachi upgrades quarry excavators

Hitachi’s ZX490LCH-6 excavator for the quarry machine market

Hitachi is now offering the powerful ZX490LCH-6 excavator for the quarry machine market. This machine replaces the earlier ZX470 and comes with increased power and performance, as well as offering increased durability and reliability over the previous model.  The machine is said to be more rugged with thicker plates in the boom and a more durable undercarriage featuring stronger track links, master pins and upper roller brackets.

Meanwhile the firm’s novel HIOS IIIB technology is said to optimise working efficiency. This uses two pumps and control valves to reduce fuel consumption and cut costs. The ZX490LCH-6 can save up to 5% fuel in ECO mode, with the same productivity as the previous model. This hydraulic technology also has a positive impact on productivity, as it has more efficient swing, boom lowering, arm and bucket roll-out.

Liebherr develops its biggest ever dozer
Liebherr is making a major step in the bulldozer market with the launch of its new PR 776 model. This is the firm’s biggest ever bulldozer and also the first hydrostatically powered crawler tractor in the 70tonne weight class. The firm claims that the machine offers significantly lower fuel consumption than other bulldozers in this class, while its hydrostatic drive also helps reduce wear and tear on tracks and chains, a key cost saving. The dozer has been designed to make it easy to use with a joystick control as well as a good all-round view of the blade edges and the surrounding area

Power comes from a 12-cylinder Liebherr diesel delivering 565kW. The PR 776 has a maximum operating weight of 74tonnes and is equipped with an 18m³ semi-U blade or a 22 m³ U blade. The ECO function is standard for all Liebherr Generation 6 dozers, including the new PR 776 and this allows operators to choose between high performance and maximum efficiency. The ECO control system enables greater travel drive efficiency in light to medium operations, and also provides greater fuel savings.

The proactive power control is another innovation and if required, engine power is automatically increased for a brief period based on need. As well as responding more rapidly, the machines offer an increase in performance and pulling power and a higher reverse speed. The intelligent engine management system combines with the power efficiency system and hydrostatic to maintain constant engine speed, increase overall machine efficiency and reduce fuel consumption. Another advantage when working in restricted spaces is the manoeuvrability, with continuous power to both tracks.

Liebherr has also custom-developed different configuration packages in-house for extreme applications such as desserts where extreme climates and low temperatures are common. The standard Liebherr fleet management system LiDAT provides an accurate, efficient overview of essential servicing work, warning messages, the machine’s position and actual consumption data and filling levels. Depending on the agreement with the customer, the data is updated several times a day and can be called up whenever needed via the Internet.

Terex Finlay’s new I-140 direct drive ø1,270mm x 1,240mm  horizontal impact crusher offers variable speed for production in recycling, mining and quarrying applications.  A significant engineering approach being introduced in this model is the material flow through the plant. The flow of material has been significantly improved by increasing the width of components as the material moves through the machine, says Terex Finlay.

The I-140’s robust and proven Terex CR032 chamber is said to give excellent reduction ratios and high consistency of product shape.  The machine features an advanced electronic control system that monitors and controls the speed of the rotor and regulates the heavy-duty vibrating feeder with integrated pre-screen to maintain a consistent feed of material into the impact chamber for optimal crushing conditions.

Material from the integrated pre-screen can be diverted to a stock pile via the optional by-pass conveyor, or it may join the crushed product on the main belt. The standard hopper capacity is 6m³.  “The introduction of the Terex Finlay I-140 represents a significant step change in our family of impact crushers. Our field test results of extensive testing have recorded significant productivity increases depending on the application, over the model that it replaces,” says Alan Witherow, product manager.

“The enhanced material flow process of the plant represents a significant step change to our engineering ethos and in due course will be extended to encompass our range of impact crushers.” A fully hydraulic apron setting assist provides convenient and efficient adjustment of the aprons while an optional under crusher vibratory plate feeder with wear resistant liners aids material discharge flow.

Case Construction Equipment is extending its new generation D Series crawler excavator offering in the earthmoving sector with the CX160D and CX180D. These two medium-range machines, like the other machines in the new D Series, have CASE’s fuel-efficient Tier 4 Final (Euro IV) maintenance-free technology with no DPF. They offer the high productivity, comfort, safety levels and low running costs for which the previously launched D Series models are known.

The new D Series crawler excavators share the Case Intelligent Hydraulic System of the previous new generation models. The improved D Series system have High Performance Hydraulics Control to boost controllability and smooth operation. The faster cycle times achieved with the more efficient hydraulics also boost profitability.

The new models deliver faster cycle times because of the new electronically controlled hydraulic pumps and larger main valve, which increase their productivity further. The new pumps and bigger valve improve the machine’s responsiveness, resulting in cycle times up to 12% faster than that of the previous generation. In addition, the new models deliver a greater lifting power.

The high productivity is further enhanced by the crawler excavators’ autonomy resulting from the high capacity fuel and AdBlue tanks combined with the machines’ fuel efficiency. Also, the AdBlue tank only needs to be refilled every 10 fuel refills, so that no time is wasted.

Atlas Copco Dynapac says that new features on the large paver range help improve paving quality and productivity, as well as operator comfort. The Dynapac SD2500 and SD2550 paver models now offer increased productivity and better ergonomics, as well as gains in paving process control. The new control features include the TruckAssist and SetAssist systems, as well as an upgraded operator panel with a new display. Jobsite planning, follow-up and paving process optimization is simplified by coupling Atlas Copco’s Dyn@Link fleet management system with BPO Asphalt.

The TruckAssist system is itended to help trucks dock correctly and safely with the paver by simplifying communication between the paver and truck driver. The system will be offered on the SD2500/2550 pavers as well as on the SD1800 paver. The SetAssist package is intended to reduce setting and transport times on the jobsite. The paver driver can save the position of the auger and screed before moving from one section to the next. Using the system will then lift the hydraulic front flap, auger and screed, lock the screed for transport and reverse the conveyor slightly. The system will be offered on the SD2500/2550 pavers as well as on the SD1800 paver.

Atlas Copco has made improvements to the screed design as the screed side shields now have integrated wiring and are equipped with power outlets on the side shields, as well as convenient transport handles. Reducing the noise emitted by the screed has led to a significant reduction in the overall noise level of the machine. Atlas Copco has also included data from optional screed width and layer thickness measurement systems in its paver operating system, PaveManager 2.0. Both systems are fully integrated with the screed controllers and the main operator display, giving all paver operators real-time information on the actual paving process.  And the firm now links the Dyn@Link fleet management system with BPO Asphalt from Volz Consulting.

The BPO Asphalt package supports construction companies in optimizing their processes and facilitates planning jobsites in terms of resources and capacity. Paving parameters, including the screed width and layer thickness, can be transferred to Dyn@Link and from there be exported for jobsite documentation or can serve as input for BPO Asphalt. The system also offers the possibility to import data from Atlas Copco’s Dyn@Lyzer compaction control system and can be linked to a truck fleet management and mixing plant systems, offering a completely integrated solution covering all aspects of the paving process.
