Every three years Messe München International hosts bauma, one of the world’s largest construction and mining expositions. The 29th bauma will take place April 19-25, 2010, in Munich. “Today bauma is the undisputed number one trade fair for the construction machinery industry worldwide,” said Klaus Dittrich, CEO, Messe München GmbH. “Not only that, it is the biggest of all the specialist trade fairs—for any industry—that take place around the globe. So bauma is big. Yet somehow this event manages to break new records every time it is held. The next bauma is no exception.”

bauma 2010 is fully booked and the exhibition space available has grown by another 15,000 m2. In total, bauma 2010 will take up 555,000 m2 of exhibition space. The organizers expect 3,000 exhibitors. In 2007, bauma had 3,002 exhibitors from 49 countries on 540,000 m2 of space, and more than 500,000 visitors from 191 countries.

As well as the high level of international participation, in terms of both exhibitors and visitors, bauma benefits from Messe München International’s strong international network of associations and sales partners. Another key reason for the success of bauma is the city in which it is held: Munich. Not only does the New Munich Trade Fair Centre offer an excellent infrastructure and the necessary capacity, but Munich itself has great flair and appeal, and first-class transport links.

“Right after the last bauma in 2007 we started planning for the next one,” said Dittrich. “In particular we have been working on transport and infrastructure improvements. We commissioned the construction of a new entrance at the northwest of the exhibition center. This was recently completed and is now open. It is expected that this new entrance will relieve pressure on the busy West Entrance [marked in purple on the site plan].”

The extra exhibition space for bauma 2010 has been gained by including new outdoor space and two temporary halls. The halls are being specially erected for the event. (Their location is marked in green on the site plan.) Foundations were poured for these halls in January and connections laid for services, such as water, waste water and IT. The Mining Hall, now successfully integrated into Hall C2, will prove to be very popular this year. It is also the location for the bauma Forum, which offers an extensive program of lectures and presentations on mining technology. In 2010, Hall BO in the International Congress Center Munich (ICM) will be occupied exclusively by Chinese exhibitors.

Times Change
Along with the economic downturn, a steep drop in demand for construction equipment occurred suddenly worldwide. “Manufac-turers of construction equipment are used to seeing fluctuations and therefore know how to handle them,” said Dr. Christof Kemmann, CEO, BHS-Sonthofen GmbH; chairman, VDMA; and chairman, bauma Advisory Board. “However, this time, the scale as well as the speed were unique.” Despite these trends, the fair is fully booked, Kemmann explained, and this might be an important indicator of the mood and situation the industry finds itself in.

During 2009, the companies belonging to the VDMA bottomed out. “Throughout the entire year, their amount of incoming orders and industry-wide sales dropped by about 50% on average; making the current volume equal to 2005 figures,” Kemmann said. The fact that the numbers of orders in the field of construction equipment and machinery have decreased in 2009 will only become visible in 2010, as lead times have become significantly longer also. Many a manufacturer will have to face a drop in sales and capacity utilization this year.”

For the mining machinery industry, 2009 was a record year in terms of sales for the VDMA. “However, the number of incoming orders fell immensely also,” Kemmann said. “Therefore, particularly in 2010, problems with regard to capacity utilization are to be expected. However, the industry hopes to maintain its overall turnover achieved in 2009 also in the running year. There are signs that at least some of the orders that were cancelled last year because of the economic crisis, will be filled this year.” There is no reason to be euphoric whatsoever, Kemmann cautioned, and companies are preparing themselves for a lean period.

The long term forecasts for the construction, building material, mining as well as the machinery industry worldwide are positive. This is thanks to rapidly growing markets in Asia and other regions, such as Brazil.

Eickhoff to Debut Autonomous Longwall Shearer
Longwall mining is one of the most productive techniques for mining coal underground. Until very recently, the shearer operator being equipped only with a hand-held radio control, had to guide the machine with all of its functions three-dimensionally through the deposit. Dust, rockfall, humidity, noise, and constraints to the operator’s vision have for many years evoked ever greater demands for automating the mining processes. The systems, however, had to be intelligent enough to orient themselves to the deposit boundaries and autonomously execute the extraction pass and guide the mining system within these boundaries.

With the automated Eickhoff SL 750 EiControl, the longwall shearer is equipped with capabilities that allow it to see, hear, and feel, according to the company. The EiControl senses are derived from features, which are designed for the harsh, potentially explosive mining environment, that include detection of the deposit boundaries by fiber-optic infra-red (IR) cameras with image processing, structure-borne noise sensors with specific parameter evaluation, monitoring of the surroundings, the anti-collision facility of the shearer using a specifically developed millimeter wave radar, and visual cameras combined with comprehensive machine diagnostics for online evaluation of the machine state.

The sensor information is evaluated by a system of algorithms and processed into control information for the navigation of the system and the automatic sequence of the mining process. EiControlPLUS is subdivided into logical partial systems which are the haulage automation and the extraction (ranging arm) automation. The haulage automation automates all motion sequences along the face during the extraction pass and includes haulage direction and speed, changes in direction, conveyor overload protection, collision warning and avoidance.

The extraction automation controls the positions of the extraction units (cutter drums) such that the mining system follows the deposit boundaries, avoiding unnecessary extraction of undesired surrounding rock.

One essential feature of the system is the open communication structure where the system’s measuring data can be transferred online to the mine control centre, and control and navigation information vice versa, through open and compatible communication paths.

This approach to shearer loader automation brings about considerable advantages in terms of sustainable extraction of raw material, and of hard coal in particular. The operators can be relieved from active control tasks in the highly stressful surroundings of the machine and focus on the monitoring and optimization tasks for the system. The EiControl system also aims for achieving the highest possible predictive utilization of the system components while eliminating unnecessary downtime as far as possible.

The mining system automatically orients itself to the deposit boundaries and thus improves the product quality by avoiding cutting of undesired surrounding rock. The subsequent coal preparation process is facilitated and goes hand in hand with reductions in the production costs and expenditure incurred by surrounding rock residues. The improved process furthermore brings about an essential reduction in the carbon footprint due to distinct energy savings.

This innovation solution became possible thanks to the fruitful cooperation between the machine builder, Eickhoff Bergbautechnik, the mining company, RAG-Deutsche Steinkohle, and RWTH Aachen as the research institute. The system has been in operation since July 2009 at the Auguste Viktoria mine, near Marl, Germany.

Liebherr Mining Truck to Take Center Stage at Largest Exhibit
The Liebherr Group is displaying more than 60 exhibits from every area of its extensive construction machinery program on bauma’s largest stand. Liebherr has developed an entirely new stand concept for its 13,500-m2 outdoor site (Stand 803-807).

A large number of new and further developed products are the main focus of interest on the new Liebherr stand. The list of exhibits includes 11 mobile cranes, six crawler cranes and hydraulic excavators, three large rotary drilling units, nine tower cranes, six mobile excavators, seven crawler excavators and the same number of wheel loaders, four crawler tractors and loaders, two telescopic handlers, a truck mixer, two mixing plants and last but not least a large mining truck. The Liebherr program of new products is rounded off by two world premieres: an innovative bulk material handler and the 282C center-steered mining class haul truck.

Conceived for mining work, the new R 954 C SHD hydraulic excavator has a service weight of approximately 62 mt. The machine’s specific configuration includes the basic unit with 9 mt of ballast, an operator’s cab raised by 800 mm and 500 mm wide double-plate crawler pads.

The R 954 C SHD develops a crowding force of 435 kN (44.3 mt) and a breakaway force of up to 355 kN (36.2 mt). The excavator’s maximum crowding length is 3.38 m, and with its discharge height of up to 6.30 m it can load all normally used haul trucks in the relevant size categories.

The R 954 C SHD’s wear-protected shovel has a capacity of 3.5 m3 when working with material with a specific weight of 1.8 mt/m3. The shape of the shovel has been chosen for effective penetration of the material and a high filling level. The well-proven parallel kinematics developed by Liebherr ensure efficiency and ample strength. Crowding force is increased continuously to a maximum over the last third of the crowding distance, and the shovel moves in parallel without subsequent adjustment. This ideal equipment concept needs no additional components and therefore avoids imposing extra weight on the working equipment.

The robust SHD undercarriage uses the longitudinal members from the next-larger crawler excavator model, the R 964 C. Together with the specially modified X-pattern center section, these ensure exceptionally high stability and optimal force flow patterns. The new undercarriage design and the use of double support-roller bearings contribute to the undercarriage’s unusually long trouble-free operating life.

Bucyrus Exhibits Passion for Mining Technology
At bauma 2010, Bucyrus will focus on longwall technology with a number of exhibits showing product innovation—and the debut of the latest evolution of its highly successful Electra range of shearers. Advances in surface mining technology will also be presented. Visitors can find Bucyrus at Booth 111/216 in Hall C2.

Bucyrus will announce a new generation shearer, the Electra 3000 Evo with advanced automation and productivity features. While keeping successful design features, Bucyrus reviewed all shearers in service around the world to refine the design. The result is a mature, flexible easy-maintenance shearer with further enhanced productivity. The ranging arm has been reengineered to make it more compact—increasing power density and minimizing disruption of material flow on the armored face conveyor (AFC). The downdrive, which is also fully modular and easy to access for maintenance, has also been redesigned to reduce maintenance time. The shearer will not be exhibited at the show, but videos and displays will illustrate the benefits.

The company will display a special roof support that can be retrofitted for Longwall Top Coal Caving (LTCC), a technology being pioneered by Bucyrus in Australia. With a support capacity of 1,362 mt (1,501 tons), the roof support is controlled by PMC-R. The Narrabri roof support exhibit features a video camera system for visual control of the entire face; powerful DN32 hydraulics for fastest advancing times; and height measurement with inclinometers.

The company will also display PF 4 line pans designed to convey 1,800 mt/h (1,984 tph) and the PF 6 line pans (6,000 mt/h (6,600 tph). Also on display for the first time is the PF 6H, a line pan that has been engineered to support heavier shearers (deadweight > 140 mt) and for future chain generations (52 mm+) and Jumbotrack 3000 haulage system.

Other underground mining technology on display includes the Power Chain, a special flight bar design allows low-profile pan, drastically reducing surface pressure and chain joint wear; the Intelligent CST (Controlled Start Transmission) system; the PMC-Family with special focus on VibraGuard; and belt systems components.

The company will also use 1:50 scale models to showcase its massive surface mining machines. The Bucyrus 8750 D3 Dragline features AC gearless technology. The revolutionary design incorporates the use of 13,000-hp synchronous motors for the hoist and drag motions, setting this machine apart from its predecessors. The AC technology used, supported by Siemens, provides for reduced downtime, maintenance costs and energy consumption, as well as increased productivity.

Another 1:50 scale model will demonstrate the HydraCrowd, the newest innovation in crowd technology developed for electric rope shovels. A hydraulic cylinder inside the tubular dipper handle replaces rack-and-pinion and rope crowd mechanisms, allowing the dipper handle to rotate, thereby eliminating harmful torsional stresses incurred during the digging motion. HydraCrowd is available on new Bucyrus 495HR/HF rope shovels, or as a retrofit option for existing Bucyrus rope shovels.   

Other surface mining technologies on display include the LatchFree Dipper System and rotary drill technology such as the Rotary Bit Change Carousel, a Forked Pipe Wrench, a reinforced 49 series drill mast, a 24 volt control system conversion, and an enhanced operator’s cab.

Grindex to Launch New Submersible Pumps
A world leader in electrical submersible pumps, Grindex has implemented some aggressive changes over the last three years. In 2007, the company moved into new facilities in northern Stockholm and began updating its business systems.

The update process also included the design of a completely new pump series; the fourth generation in the company’s history. The new pump series was introduced to the market in the first quarter of 2008. Compared to earlier pump generations, the pump’s wear resistance has been tripled, in some applications even more. This has been achieved by preventing abrasive particles from reaching the vulnerable parts of the pumps, thus minimizing wear. This makes the pumps capable of maintaining capacity while operating in really demanding applications.

At bauma 2010, a new generation of slurry pumps will be introduced to meet the needs for extra abrasive resistant submersible pumps. The series will comprise nine pump models with motor sizes from 5 to 70 kW.

The company will also introduce a new submersible drainage pump Master SH. The pump has been designed to deliver water up to over 80 meters in one single step. This is possible thanks to the double stage impellers and thorough design. The Master SH pump is ideal for operation in deep excavations where high head pumping is common, such as in underground mines as well as in open-pit mines.

Rema Tip Top Offers Enhanced Service Strategy
In addition to supplying the components needed to maintain conveyor systems, Rema Tip Top is also branching into service-oriented solutions for mines. The company now includes its Total Cost of Ownership (TCO) models in every service program and it presents all necessary service components in a structured and clear fashion. TCO is probably best described as an accounting procedure that helps companies to record and to reliably estimate all costs associated with capital investments. These not only include procurement costs, but also numerous different expenditures made that have an effect on profitability down the road.

The overall goal is to examine known cost drivers more closely and influence their effects on operating or company results in a positive manner. TCO is, however, also a suitable aid in identifying hidden costs, preferably before an investment decision is made. Moreover, TCO permits a further, much more important examination perspective, namely that of increased use and effectiveness, in this sense almost identical in its meaning to that of the term ‘added value.’

In addition to TCO, Rema will also showcase some new products at bauma. The company has developed RemaStarm a high-quality wear-protection material which is impressive because of its manifold features. The lining material is based on a thermoplastic polyurethane. It is extremely resistant to wear. It shows a very high grooving and cutting resistance. It stays flexible at extremely low temperatures. It is resistant to oils, greases and a wide variety of solvents. Its high aging resistance is a further advantage.

Rema Goo is a new product which helps to speed up conveyor belt repairs. It is a specifically designed solvent-free two-component polyurethane repair paste which makes it possible to repair damage to conveyor belts in an extremely short time. The material stays elastic. It shows no signs of fatigue or aging. It does not shrink after application and is resistant to UV-rays. It hardens to approximately 60 Shore A, which equals the hardness of conveyor belt rubber covers.

Rema recently acquired shares in Dunlop Industrial Products, South Africa, a major belting supplier. The company is now able to supply high quality conveyor belting to clients across the globe.

Wirtgen Presents the Largest Surface Miner
In 1980, Wirtgen built the first surface miner for mining minerals in opencast deposits. Today, Wirtgen is the market leader in this segment, offering a technically mature product portfolio for opencast mining that has been tried and tested in operations around the globe. The latest machine, the large 4200 SM, has a total weight of more than 200 mt and a length of over 30 m. The huge mining machine is the heaviest and longest exhibit of the entire Wirtgen Group exhibition stand.

The 4200 SM will represent the successful surface mining division of Wirtgen that consists of three machines for opencast mining in different performance classes. Surface miners from Wirtgen offer cutting widths ranging from 2.20 m to 4.20 m and cutting depths of between 20 cm and 83 cm. Wirtgen is the only manufacturer covering a scope of performance ranging from 100 mt to 3,000 mt/h. This high measure of productivity is attributable to the miners’ efficient cutting technology plus a wealth of experience gained in three decades of application technology.

Productivity is clearly also the hallmark of the new 4200 SM: the miner is a high-performance machine suitable for mine operators and customers in large-scale opencast mining whose goal is to achieve an annual mining capacity in soft rock of up to 12 million mt while wanting to make full use of the benefits offered by Wirtgen’s selective mining technology that enables cutting, crushing and loading in a single working pass.

The 4200 SM is available in two different configurations for operations in either hard or soft rock. For applications in soft rock with unconfined compressive strengths of up to 50 MPa, the 4200 SM is equipped with a 4.20 m wide cutting drum unit with larger cutting diameter, thus permitting a cutting depth of up to 83 cm. The largest Wirtgen miner can alternatively be equipped with a drum assembly offering a cutting width of 4.20 m and a cutting depth of 65 cm for applications in hard rock with unconfined compressive strengths ranging from 30 MPa to 80 MPa.

The heavy-duty machine is equipped with a 16-cylinder diesel engine from Cummins, making it the ideal candidate for a wide range of applications as its power of 1,194 kW/1,623 PS offers tremendous reserve capacity. Generously dimensioned tanks offering capacities of 2,900 l for diesel and 10,000 l for water additionally increase the miner’s uptime.

A two-stage conveyor system with 1,800 mm wide primary and discharge conveyors and optional discharge conveyor lengths of 12,000 mm or 16,000 supports the surface miner’s impressive cutting performance of up to 3,000 mt/h. The conveyor’s large slewing angle of 180º, flexible height adjustment and variable conveyor belt speed ensure smooth loading of large transport trucks even in restricted space conditions.

Putzmeister Pumps Tailings and Fly Ash

Putzmeister Solid Pumps GmbH (PSP) will display a high-pressure resistant, upgradeable high-density solids pump for transporting building materials underground.

The HSP 25150 SP is a large-volume pump with two individually-controlled pistons. PSP specifically designed the pump to convey tailings and to pump fly ash over great distances. To achieve as constant a delivery as possible without pressure peaks, Putzmeister can, on request, equip these mining pumps with Pressure Constant Flow (PCF) control.

Putzmeister has designed the HSP pump head with a modular structure. This design makes a significant contribution to reducing operating costs. The replacement of worn parts now only involves replacing the actual worn-out components and no longer encompasses the entire pump head.

When switching from pressure stroke to suction stroke, seat valves in the HSP pump head with extremely accurate closing characteristics prevent the conveyed material from flowing back out. This means that pressures of 150 bar are possible in continuous operation even when pumping paste-like and highly viscous media with small particle sizes. The new seat valve pump for solid matter is designed with a maximum 20 mm diameter. Thanks to the high-volume delivery cylinder, the HSP 25150 SP achieves effective outputs of approximately 250 m3/h, depending on the material to be conveyed and the fill level of the delivery cylinder.

If the output needs to be further increased, the new high-density solids pump can easily be modified into a multi-cylinder delivery unit. Any number of cylinders is possible with evenly offset piston strokes. The result is a pump system designed to suit each individual delivery job, with an impressive, extremely even output flow rate at high pump outputs. PSP also offers subsequent “upgrading” of the pump installation in order to produce a higher delivery rate.

Dana Develops Drive Train for Wheeled Loaders
At bauma this year, Dana will introduce an optimized drive train solution for 16-metric ton (17.5-ton) front-end loader vehicle applications through a system that includes a Spicer 319 summing motor, two Spicer Model 114 planetary drive axles, and the Spicer Compact Series Model 2035 driveshaft.

The Spicer 319 summing motor transfer case provides maximum tractive performance and high efficiency. Targeted for applications requiring 104 to 164 kW (140 to 220 hp), this transfer case employs two hydrostatic motors each with optimized gear ratios. To maximize efficiency at higher vehicle travel speeds, a clutch automatically disconnects the low-speed, high-gear-ratio motor, allowing the high-speed motor to function alone.

The Spicer 319 summing motor transfer case delivers seamless continuous variable transmission (CVT) performance from 0 to 40 km/h (0 to 25 mph).

The Spicer Model 114 drive axle includes a limited-slip differential lock that provides a 45% locking capacity, delivering excellent tractive force and nimble vehicle steering for front-end loader applications. The Spicer Model 114 axle can be configured with a variety of other hydraulic-locking differential options, including dog clutch and multi-disc clutch. Inboard wet disc brakes offer proven fail-safe stopping performance and energy absorption, while a fail-safe park brake featuring internal negative SAHR is available as an option.

The Spicer Model 114 axle includes 6.00-to-1 ratio outboard planetary wheel ends with 425 mm wheel B.C. mountings, self-adjusting internal wet brakes, and a trunnion mounting option.

Tenova Takraf Will Display Mobile Crushing Station, New Surface Miners
Results of recent feasibility studies conducted for overburden removal systems show an overall life cycle cost which clearly favors In-Pit Crushing and Conveying Systems (IPCCs) employing mobile crushing plants, conveyors and mechanized spreading equipment over other solutions such as haul trucks. In 2009, Tenova Takraf supplied and commissioned a mobile crushing plant rated at 12,000 mt/h for a coal mine in Queensland, Australia.

This unit has a slewable superstructure and slewable discharge boom conveyor that may be positioned at different angles to the mining face and thus provides very high operational flexibility. A 50-m3 electric shovel feeds the plant. The shovel pivots and travels about the receiving hopper in an incremental radial pattern. Concurrent relocation of both the mobile crusher and the rope shovel occurs approximately every eight hours in this specific instance. During the loading operation the hopper rests on the ground to avoid propagation of shock loads through the crushing station.

Starting from this concept Tenova Takraf embarked on the development of a more simplified plant without the need of the slew function of the entire superstructure. The result is the Takraf mobile crushing system (TMCS) which is now offered as a modular system for a capacities range of about 4,000 to 12,000 mt/h. It may be combined with a belt wagon or a mobile conveyor bridge which is capable of spanning up to three benches of 15-m height or more, from one face conveyor. The TMCS can be equipped with either a double roll crusher or with a sizer.

During December, two Tenova Takraf TSM 300 surface miners began production at the HWE Mining’s Yandi iron ore ine in Western Australia.

During the initial start up and training period the cutting capacity averaged 480 mt/h to 1,110 mt/h depending on the material’s compressive strength.

The TSM 300 uses a front cutting drum with a direct twin drive. That allows for a cutting depth of 800 mm. Due to its specific cutting drum design with top-down cutting, the surface miner consistently produces a small product size, without additional crushing. Standard features include a spacious operator cabin with two full size access ways and a trainer seat. It’s advanced on-board machine monitoring and diagnostic system with full size screen and clear text messaging allows for easy control and adjustment of machine parameters for best performance under changing ground conditions.

Duferco Clabecq Supplies High Quality Steels
Manufacturers using abrasion resistant steel to produce heavy machines are looking for light steel components offering longer life cycle and less replacement. As they enable weight reduction, demand for these special steels is increasing. Duferco Clabecq is fulfilling this specific need with “Quard,” its new abrasion resistant steel. Thin and wide, its plates innovate by their consistency regarding workability, their surface finish and their flatness.

Consistent mechanical characteristics make it easier for the manufacturers to cut, bend and weld steel plates. With constant mechanical aptitudes and thanks to tight tolerances, processing is achieved faster and more efficiently. Quard’s consistency matches manufacturers’needs for easy processing.

The excellent surface finish is a direct consequence of Duferco Clabecq’s rolling process, combining a reversed quarto mill and a 4-stand finishing mill, next to which an accelerated cooler has been installed.

With maximized control on production parameters and thanks to its newly commissioned leveler, Duferco Clabecq is able to supply plates with flatness in accordance to the highest standards (EN 10029, class S).

Duferco Clabecq supplies Quard today with a hardness of 400 and 450 Hb in a thickness range between 8 to 20 mm. As a result of an investment of about €100 million, Duferco Clabecq will extend its range of Quard with thickness from 3 to 40 mm and with hardness up to 500 and 550 Hb. Duferco Clabecq has invested in the latest technology tools with enhanced precision to ensure a sustained productivity while delivering plates with accurate flatness and superior surface finish.

Duferco Clabecq is a leading manufacturer of medium and heavy steel plates in thickness range from 3 to 120 mm. It produces high added value steels including structural, shipbuilding, pressure vessel, high strength and abrasion resistant steel as well as plates for pipes. Based in Ittre (Belgium), it employs more than 500 people. It has a yearly production capacity of 750,000 mt. The company is a part of Steel Invest & Finance, the joint venture between NLMK (Russia) and Duferco (Switzerland).

Sandvik’s Electric LHD Will Turn Heads
The latest addition to the Sandvik line of load-haul-dump (LHD) units for underground mining is the new 14-mt electric LHD that melds higher productivity with lower operating costs and reduced environmental impact with all the strengths of diesel machines.

Similar to all Sandvik loaders, the 14-mt eLHD incorporates key features of the recently launched diesel machines, such as upgraded cabin design and Vehicle Control and Management system (VCM). The electronic control system incorporates a state of the art user interface with enhanced diagnostics and a platform for Sandvik’s Automine technology, plus an upgraded electric system that are designed to interface optimally with the electronic control system.

Sandvik loaders’ specialty upgraded electric and hydraulic systems and improved tramming capacity deliver excellent productivity, reliability and performance. Offering extended operating range with up to 400 m of cable, they are ideal for use in all applications where the hauling distance is short and operations are repetitive.

Easy to service and maintain, eLHDs also offer reduced downtime by improved diagnostics and trouble-shooting with the VCM system. Additionally, new, top-notch manuals and up-to-date training materials make them perfectly suited for all global users with reasonable operational and
management practices as required for electric fleet.

Higher productivity is offered with electric motor’s peak torque, resulting in faster bucket filling and better acceleration. The electric model features 14,000 kg (30,865 lb) of tramming capacity, buckets ranging from 4.6 m3 to 7 m3, three-phase, squirrel-cage 45 kW pump and 132 kW drive motors with Dana 5000 series gearbox and Posi Stop axels. Sandvik eLHDs features include better visibility with horizontal cable reel, better fire safety as there is no need for flammable diesel fuel, no hot engine parts and no exhaust fumes.

SSAB Envisions a Stronger, Lighter and More Durable World
SSAB produces steels that are among the strongest in the world. This enables customers to make lighter, stronger and more durable products, which offers major environmental benefits to customers and the surrounding world. SSAB is a leading producer of high strength and quenched and tempered steels. The SSAB product brand name portfolio includes numerous brand names as well as a few rising brand names, such as Hardox, Domex, Weldox, Docol, Armox, Prelaq and Toolox.

The properties of the products in terms of strength, abrasion resistance, wear resistance, bendability, weldability, etc. have led to their established strong position in the market. SSAB steels enable customers to manufacture products that are lighter, more durable and stronger than products made of traditional steels.

SSAB was founded in 1978 by the merger of three Swedish steelmakers. But the steelmaking expertise at SSAB is much older than that. The Swedish steel companies that merged into SSA trace their origins to the end of the 19th century and the beginning of the 20th century. SSAB decided at an early stage to become a niche player in steel sheet and heavy steel plate. SSAB advanced high strength steels are characterized by a combination of high strength and toughness, which is due to the purity of the steel and a unique production process. In 2007, SSAB acquired the North American steel company IPSCO, which has two modern heavy plate steelworks. As a result, SSAB now also has a strong presence in the North American market.

After five years of development, SSAB will debut its new WearCalc 2.0 software at bauma. The software allows mine engineers to quickly and easily calculate the relative service life of abrasion-resistant spare parts. Combined with comparative material and production costs, this allows quick selection of the optimum materials for the job.

Material price and manufacturing costs are relatively easy to establish. But predicting the service life for various materials under different conditions is much trickier. The former version of WearCalc only predicted sliding wear. WearCalc 2.0 also predicts erosive and impact wear as well as sliding wear for all types of Hardox wear plate.  Development of the impact wear model required extensive testing both in the laboratory and at a range of industrial sites. The model covers two types of impact damage: Severe damage involving crater formation and extruded lips during impact, and milder damage resulting in plastic deformation of the surface.

Volvo Pulls Out All the Stops
Volvo will unveil innovative new products and services under the guiding themes of being a global leader in fuel efficiency and a provider of total solutions to customers. In addition to a range of more than 60 machines on the stand, including highlights of the substantial fuel saving provided by the ‘OptiShift’ technology fitted to the new L150F, L180F and L220F larger wheel loaders. Volvo has made acommitment as a total solution provider; a comprehensive range of products and services designed to carry each machine through a long and productive life.

The company’s presence at bauma will be divided into a 2,454 m2 indoor display area and a 7,410 m2 outdoor demo zone. The indoor area will feature static new products and much of the space will be given over to the company’s growing portfolio of service offerings. The Volvo event team will be primed to deliver all the ways Volvo dealers can work with customers to improve productivity, maximize machine uptime, reduce risk and take greater control of costs.

The outdoor portion of Volvo’s exhibition space is more practical in nature, with the central area dominated by a demonstration arena. A special area with two compact excavators offers ambitious operators the chance to test their skills, and to qualify for the final of the best European operator—as well as challenging the Eco Operator using Volvo’s own training simulator.

Atlas Copco Debuts Equipment and Services
Atlas Copco’s will display its Minetruck MT42 at bauma, which represents the company’s next generation of underground trucks. This high-speed 42 metric ton (mt) articulated truck has been designed to maximize productivity as well as provide increased safety and operator comfort in underground haulage applications. The MT42 is available now in Scandinavia and Canada and will be launched globally in 2011.

The Minetruck MT42 is powered by a fuel efficient, low-emission Cummins QSX15 520 hp EPA Tier 3/Stage IIIA engine, coupled with proven drivetrain components, delivering reliable performance and high speed on ramps. The transmission has eight forward and two reverse gears and features a self-diagnostic system for rapid troubleshooting.

Operator comforts in the standard ISO ROPS/FOPS certified cabin include an air suspended forward-facing seat, a clear, multifunction display monitor, air conditioning and a trainer’s seat. The operator’s sound exposure is below 80 dBA in the cabin. Front axle suspension further contributes to operator comfort, while also allowing greater speeds on mine roadways.

An extensive, 12-month field test at Boliden’s Garpenberg mine in Sweden proved the capabilities of the Minetruck MT42, while also winning praise from the operators. The articulated steering increases maneuverability and allows agile cornering, while the dump system can discharge a full load in just 13 seconds. Rear facing cameras, one backup camera and one loading camera covering the box, complement the operator’s view from the cabin.

In addition to the MT42, the Scooptram ST7 has a tramming capacity of 6.8 mt, articulated steering and an oscillating rear axle. It is powered by a clean burning, 193 hp 6.7 liter Cummins Tier 3 engine and benefits from traction control to increased loading performance and improved tire life.

Safety is further enhanced by three emergency machine stop buttons and a system that applies the brakes, blocks steering, and prevents bucket movement when the cabin door is open.

Deutz Offers More Flexibility
The Deutz stand, measuring more 400 m², will feature an extensive range of engines to meet the more stringent demands of the Tier 4 Interim/Tier 4 Final emissions standard and will offer existing and prospective customers a comprehensive portfolio of exhaust gas after-treatment components.

A particular highlight, which Deutz is presenting under the provisional model designation of TCD 20XX, is a completely new engine developed for the construction industry. This ultra-compact, 2.9 liter cubic capacity, four-cylinder in-line engine was specifically developed to meet the requirements of the construction industry in the 28- to 55.9-kW power range. The 20XX engine has been cleverly designed so as not to exceed the 56 kW threshold and does not need a diesel particulate filter nor its associated complex regeneration technology. For most applications, it only needs a diesel oxidizing catalyst (DOC), an inexpensive and easy-to-install exhaust gas after-treatment system to meet Stage IIIB and Tier 4. The optional attachment components for the 20XX have been designed to offer customers more flexible installation options and significantly lower installation and operating costs.

For the higher power range, Deutz is presenting the TCD 2013. Producing 160- to 250-kW at 2,200 rpm, this liquid-cooled six cylinder in-line engine features ruggedness and high performance. The TCD 2013, equipped with charge-air-cooled turbocharger, cooled external exhaust gas recirculation and diesel particulate filter, satisfies the emissions standards for mobile working machines in accordance with the EU Non-Road 2004/26 Directive, EU Tier III B and U.S. EPA Tier 4 Interim. It benefits from the Deutz Common Rail high pressure injection system, electronic engine control allowing intelligent engine management adjustments, plus integral power take-off options during wheeled operation. The lean engine construction and variable design of the front end of the engine have resulted in maximum flexibility. Fuel economy figures, simple and inexpensive installation and long service intervals also make for great economic efficiency. Low noise emissions ensure further cost savings as regards sound attenuation measures.

Orlaco Offers Monitoring Solutions

Orlaco (Stand A3.501) will present its newest camera/monitor solutions for off-road equipment, including the Spectrum scanner, a radar system, and the Compact Pin Hole (CPH) and the pan-and-tilt Zoom cameras.

The Spectrum scanner auto-searches for the optimum frequency for data exchange between camera and monitor. The system selects its frequency from up to eight different frequencies. The driving force behind this development was the need for highly reliable and available images, because these features are essential for both safety and comfort.

The company’s new radar system detects objects and persons in the immediate vicinity of a vehicle. If these are identified, the view system automatically switches to the camera on that side of the vehicle. This active signaling represents a significant improvement in safety at the workplace.

Orlaco developed the Zoom camera in-house. The pan and tilt function is fully integrated into the housing of the Zoom camera. The camera always remembers its last position. In case of uncontrolled camera movements, for example when it is hit by objects, the camera automatically returns to its last position. The CPH camera is mounted on the fork carriage or in the attachments and gives a view of the position of the load.
