A lot has happened since BAUMA 2007, with the industry in many ways coming full circle. Despite the cancellation of other construction-related events in 2008-09, at January’s media event the organisers were upbeat, stating that, despite an increase in exhibition space of 15,000m2 to 555,000m2, more than 3,000 exhibitors were expected at April’s event, and more international exhibitors than three years ago. Perhaps because of the sheer size of BAUMA and the fact that other construction events of late have been somewhat lacklustre, companies may have chosen Munich as the next worthy venue at which to commit to a significant presence.
Organisational improvements include a new entrance at the northwest corner of the site, more parking capacity, new temporary buildings on the open-air site, and a more extensive shuttlebus service to the car parks, hotels and airport. A new visitor admission system is also in place to help shorten waiting times at the entrances, while delegates can now register online and print a ticket from home.
For domestic companies, things have been ticking over quite well. The VDMA Mining Equipment Association has reported that, despite the global economic downturn, 2009 saw a 10% increase in turnover – approximately €560 million – across the German mining equipment-manufacturing sector, making it one of the best years on record. Overall turnover for German mining-equipment manufacturers for 2009 is expected to be around €4 billion.
The reasons for this increase are the high level of orders in 2008 and the successful opening of new markets, especially in Central and South America. Of course, many of the key mining machines have long lead times, so part of this will reflect the tail end of the last boom, but the figures are still very positive.
As usual, many companies have chosen BAUMA to show off new technology and equipment. Typically, the majority of this is focused on the construction and quarrying markets. However, there is still a lot of interest in mining terms. The following summarises some of the mining-relevant information released by exhibitors, divided into four categories: surface mining; underground mining; engines and pumps. Due to the sheer volume of firms exhibiting, this only represents a fraction of what will be on show in April.
The show’s star mining attraction will be Liebherr’s T282C, which is likely to be the largest machine at the event, construction cranes aside. This is the latest variant of the 400 short ton T282 series, taking over from the T282B and offering a Tier 2-compliant engine, as well as a number of other improvements. This month’s news pages outline the first fleet delivery of this model to Wyoming in the US.
In addition, the new hydraulic R9100 excavator will gain its first public viewing. It has a 6.8m3 backhoe/ 7m3 face-shovel capacity and a new V12 Liebherr engine, although it will also be available with a Cummins QSK23. Another new, smaller excavator, the R954C will be another newcomer. In other equipment, the company’s new ADT, the 30t-capacity TA230 Litronic, will also be on show, as well the 31.83kg L586 2plus2 wheel loader. Among the largest hydraulic excavators there is likely to be an update of the R996 later this year, while the all-new R9800, first announced officially at MINExpo 2008, is currently working in Australia for contract miner Thiess at a coal mine in Queensland.
News from Komatsu at BAUMA includes a new official distributor for Sweden – Hesselberg Maskin. Hesselberg Maskin is owned by AS Sigurd Hesselberg, a well-established company that has been Komatsu’s Norwegian distributor since 1974 and boasts extensive experience in construction machinery. In equipment, the PC200-8 Hybrid excavator, the world’s first hybrid construction equipment, will be presented for the first time at BAUMA. In technology, its Komtrax exclusive satellite-monitoring system will be on show.
Designed to optimise fleet management, Komtrax allows proactive and preventive maintenance of construction and mining equipment. ADT major Bell will be showing its new 6x6 Hooklift-Trucks, based on Bell’s B25D/B30D models and the ‘narrow’ version of the Bell B25D, both of which are to be presented on BAUMA. Excellent off-road qualities and high loading capacities with low ground pressures are the main advantages of modern 6x6 ADTs for hooklift and container operations in various applications. Also on show will be the new Bell B45D, which established itself as the first real 40t ADT in a new performance class within the Bell programme, complementing the Bell B50D.
South Korea’s Doosan will display the new 70t DX700LC, which is now the largest in the range of Doosan crawler excavators, and designed and built to meet the needs of heavy-duty mining and quarrying applications, as well as major infrastructure construction projects. It has a long carriage (LC) design, which, in combination with the undercarriage, expands to a maximum working width of 4,000mm, offering optimum stability and safety in all kinds of digging, lifting and loading applications. To meet the requirements of different markets, three arms of varying length will be available for the DX700LC.
BAUMA will see the world premiere of Wirtgen’s 4200SM surface miner, outlined in detail in last month’s surface miners article. With a total weight of over 200t and a length surpassing 30m, the huge machine will be the heaviest and longest exhibit on the entire Wirtgen stand. The 4200SM is available in two different configurations for operations in hard or soft rock. For applications in soft rock with unconfined compressive strengths of up to 50MPa, the 4200SM is equipped with a 4.2m-wide cutting-drum unit with larger cutting diameter, thus permitting a cutting depth of up to 83cm.
Given the sheer size of most of its equipment, most surface Bucyrus machines at the show will be represented by scale models, including the 49 series of rotary blasthole drills, the 8750 walking dragline and HydraCrowd-equipped 495 rope shovel. Underground products will include the 0.55-7m roof-support range, the PF4/PF6 and PF6H line pan ranges, the full range of Power Chains and the Intelligent CST Drive Systems for longwall systems.
In 2009, Tenova Takraf successfully supplied and commissioned a TCMS (Takraf Mobile Crushing System) mobile crushing plant, rated for 12,000t/h, at the Clermont mine in Northern Queensland, Australia. At BAUMA, the company will be outlining some of the configurations to the basic design. These include the TMCS/cb (the cb standing for ‘conveyor bridge’), which is adapted for a mobile conveyor bridge. Having eliminated the main slewing and slew-gear function of the upper structure, the TMCS concept now allows the arrangement of the travel crawlers close to the head and tail extremities of the rigid superstructure. This is most advantageous for the support of the receiving hopper, located right above a pair of equalised crawlers.
During loading of the receiving hopper and apron feeder by the rope shovel, the high-impact loads are transferred directly into the ground via two crawlers, which form a two-point support at this location of the plant. Full mobility is thereby provided, which is advantageous when cutting ramps or working away from a mining face.
The opposite crawlers beneath the conveyor are designed as a slewable, two-crawler undercarriage, which supports the equipment via a ball point. In conjunction with the two crawlers under the receiving hopper, this arrangement provides a clearly defined three-point support, so the crawlers can adjust themselves to the prevailing ground conditions.
Caterpillar’s exhibit will mainly focus on the construction sector, but mining-relevant equipment includes the 993K wheel loader, D7E electric-drive crawler dozer, and a new quarry body for the 770 truck. Also discussed at the show will be the Connected Worksite technology with next-generation product link and new, integrated Cat Grade Control.
China’s LiuGong will be displaying its 888III wheel loader – the largest that it currently exports. Later in 2010, the firm expects to begin shipping its largest wheel loader, the 899III. The 888III is designed to handle the toughest working conditions and heavy loads under very long, severe duty cycles. It has a Cummins engine and a rated power of 250kW, and the ability to handle buckets with capacities of 3.8-6m³.
Hitachi will exhibit several new large wheel loaders. The ZW330, ZW370 and ZW550 are the first machines to be launched in Europe since the alliance between Hitachi Construction Machinery (HCM), Kawasaki Heavy Industries (Kawasaki) and TCM Corporation (TCM) was formed in October 2008. HCME has selected the ZW370 and ZW550 for its exhibition stand at Bauma.
Finally, Terex, fresh from having sold its main mining business to Bucyrus, has launched two new ADTs – the TA400 and 30t TA300. The TA400 standard features include its Tier 3-compliant, fuel-efficient 336kW diesel engine, maximum rim-pull and gradeability for negotiating inclines, as well as a large body capacity with low body weight to maximise load size and retention. All three axles on the Terex TA400 are locked in permanent all-wheel drive (6×6), and these articulated trucks are equipped with oil-cooled, wet disc brakes on all six wheels.
While not as high-profile as the surface machines at BAUMA, there will still be some important new pieces of underground equipment on display. Top of the list is Mine Master’s all-new Face Master 2.3 twin-boom underground jumbo, featuring a 96kW diesel engine, making the tramming system extremely powerful and giving the jumbo good traction in hard terrain. The machine also incorporates an electric system with soft start-up, reducing electricity input by up to 20%. An improved hydraulic system provides better control of drilling, making it more suitable for drilled rock formations and adjusts the system to different rock applications. The frame of the machine, as well as the operator’s protection canopy, are designed and manufactured from high-quality steel.
Sister company GHH is developing its latest LF10/11 LHD model, which is currently being tested in a copper mine in Chile, while the third main company in the group, Hazemag, will show a new version of its EL 160 Dinting Loader EL 160. The EL 160 series is already very successful in the coal-mining industry in the field of maintenance and repair of underground galleries. At BAUMA, Hazemag will present the newly-developed version of the EL 160 LS, which has a gun-mount for blast-hole and anchor borehole drillings. By using modern construction and production technology, as well as high-quality materials, this new gun mount achieves a low deadweight and very high stability.
Schopf Maschinenbau will launch its newest machine at BAUMA, a 10/12t underground LHD with Z-linkage, centre oscillation, latest engine standards and an ergonomic driver stand. At the last BAUMA in 2007, Schopf introduced the first underground loader in this new line. The extra low-profile underground loader, SFL 60 XLP/FLP, has since been working very successfully in hard rock, as well as in a flameproof version in coal mines.
Sandvik Mining and Construction will showcase its new electric 14t LHD, the LH514E. The model has a very low emission count, making it ideal for higher productivity, and a lower cost in various applications while ensuring a better working environment. Like all Sandvik loaders, it incorporates key features of the recently-launched LH514 diesel machines, such as an upgraded cabin design and Vehicle Control and Management system (VCM).
Previously announced in Mining Magazine, Atlas Copco has two products for underground mining: the MT42 Minetruck and the Simba S7 D. The Simba S7 D is now available for longhole drilling in the small-to-medium range drift size. The focus has been on developing a versatile, reliable and safe drill rig for mining. The rig is based on a modern design with many components in common with the successful Boomer S1 D face-drilling rig. The S7 D will be the direct replacement for the well-proven Simba 1257.
The new 42t Minetruck MT42 is now available in Scandinavia and Canada, and will be launched globally in 2011. It is powered by a fuel-efficient, low-emission Cummins QSX15 520hp 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.
Eickhoff will display its SL750 EiControlPlus automated shearer loader; a machine with which it is possible for the first time to realise the idea of an automatic longwall operation where operators can focus on monitoring functions in secure and unencumbered surroundings. The machine state information, monitoring information on the surroundings and the collision hazards of the mobile machine, and the information on the position of the mining system relative to the deposit boundaries is detected by newly-developed, linked sensors. Algorithms evaluate the sensor data and generate control information based on it.
Grindex’s new Master SH dewatering pump has been designed to deliver water up to over 80m in one single step, made possible due to the double-stage impellers and thorough design. vThe Master SH pump is ideal for deep excavations where high-head pumping is common, especially underground. Compared to earlier generations, wear resistance has been tripled by preventing abrasive particles from reaching vulnerable parts of the pump.
Godwin Pumps will debut its newest CD Series addition, the model CD500M Dri-Prime pump. The 600 x 400mm centrifugal pump is capable of flow rates up to 3,066m3/h, heads to 61m and solids handling up to 104mm in diameter.
ITT Water & Wastewater will present a cross-section of all portable Flygt pump series, from the handy READY up to the 900kg BS 2400. ITT’s new two-stage 2600 series Flygt pump, the 2660 ST, can be used in a broad range of mining applications. The pump is based on the design of the 2600 series and has a zero leakage ‘Active Seal’, which contributes to longer intervals between oil changes and maintenance.
Tsurumi Europe will launch a new dewatering pump, the NK 2-22, on the European market and a GPN-series excavator adaptor for efficient sand-water discharge. The NK 2-22 is a heavy-duty, high-head, single-phase, submersible pump.
In slurry pumping, Putzmeister will display the HSP 25150 SP. This is a particularly high pressure-resistant, upgradeable high-density solids pump for transporting building materials underground. The principal areas of application for this pump system will be gold, diamond and zinc/lead mines, which need to stabilise their pitheads, backfill demineralised chambers economically or pump fine-grained excavated material out of the processing plant.
Cummins will reveal four new engines for EPA Tier 4 Interim and EU Stage IIIB emissions regulations. The ‘4 More For Tier 4’ will mark the debut of Cummins’ next-generation of four-cylinder QSB3.3 and QSB4.5 engines for compact equipment, together with a first showing of the all-new QSX11.9 and QSX15 heavy-duty engines. The four new Tier 4 Interim engines will be displayed at BAUMA as complete air-intake-to-exhaust after-treatment systems, with all key technologies integrated by Cummins.
The compact 3.3l and 4.5l QSB engines extend across the 56-119kW power range, enabling OEMs to standardise their four-cylinder installations with common Tier 4 Interim engine architecture. The all-new 11.9l and 15l QSX engines cover a broad 224-447kW power band. The heavy-duty duo shares the same performance-enhancing technology for Tier 4 Interim, such as Cummins’ new XPI common-rail fuel system.
All the Tier 4 engines launched at the show will be suitable for underground applications that do not require MSHA-type emissions. The QSK19 will also be on show, which is used in the largest Sandvik and Atlas underground LHDs. Finally, there will also be a 2,610kW-rated QSK78 mining engine, which is used on some of the leading ultra-class mining trucks.
Deutz will also 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 clients a comprehensive portfolio of exhaust-gas after-treatment components.
Hardened-steel market leader SSAB has invested heavily in quenching, tempering and rolling-mill equipment and procedures to produce thicker, hardened plate of consistent high quality. By increasing the maximum plate thickness for Hardox, Weldox and Toolox, SSAB states that it is supporting the push for more efficient machines with greater output.
Hardox is now available up to a plate thickness of 160mm, depending on the hardness grade. A new product from SSAB is WearCalc 2.0, a software package that allows customers to easily calculate the relative service life of abrasion-resistant wear parts.
Duferco Clabecq has a new grade of Quard, its abrasion-resistant steel. The firm supplies Quard today with a hardness of 400-450Hb in a thickness range of 8-20mm. As a result of a major investment, Duferco will extend its Quard range to cover thicknesses of 3-40mm and hardnesses up to 500-550Hb. Duferco says it has also invested in the latest technology with enhanced precision to ensure sustained productivity, while delivering plates with accurate flatness and superior surface finish.
ESCO will present its latest innovation in tooth systems for demanding applications. Posilok Plus provides the same strong reliability as the ESCO Posilok system, but with the added safety of a hammerless locking device. Cast in premium ESCO alloys, the company says Posilok Plus offers “an unprecedented blend of performance, wear life, safety and ease of use”.
The Posilok Plus system is available to fit mining-class hydraulic face shovels, excavators, draglines and cable shovels. In addition, the new U60 size of ESCO’s popular Ultralok system, specifically designed for the large quarry market, will be prominently displayed at the event.
Organisational improvements include a new entrance at the northwest corner of the site, more parking capacity, new temporary buildings on the open-air site, and a more extensive shuttlebus service to the car parks, hotels and airport. A new visitor admission system is also in place to help shorten waiting times at the entrances, while delegates can now register online and print a ticket from home.

Finally, there will also be a 2,610kW-rated QSK78 mining engine, which is used on some of the leading ultra-class mining trucks.
Deutz will also 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 clients a comprehensive portfolio of exhaust-gas after-treatment components.
Steel and wear parts
Hardened-steel market leader SSAB has invested heavily in quenching, tempering and rolling-mill equipment and procedures to produce thicker, hardened plate of consistent high quality. By increasing the maximum plate thickness for Hardox, Weldox and Toolox, SSAB states that it is supporting the push for more efficient machines with greater output.
Hardox is now available up to a plate thickness of 160mm, depending on the hardness grade. A new product from SSAB is WearCalc 2.0, a software package that allows customers to easily calculate the relative service life of abrasion-resistant wear parts.
Duferco Clabecq has a new grade of Quard, its abrasion-resistant steel. The firm supplies Quard today with a hardness of 400-450Hb in a thickness range of 8-20mm. As a result of a major investment, Duferco will extend its Quard range to cover thicknesses of 3-40mm and hardnesses up to 500-550Hb. Duferco says it has also invested in the latest technology with enhanced precision to ensure sustained productivity, while delivering plates with accurate flatness and superior surface finish.
ESCO will present its latest innovation in tooth systems for demanding applications. Posilok Plus provides the same strong reliability as the ESCO Posilok system, but with the added safety of a hammerless locking device. Cast in premium ESCO alloys, the company says Posilok Plus offers “an unprecedented blend of performance, wear life, safety and ease of use”.
The Posilok Plus system is available to fit mining-class hydraulic face shovels, excavators, draglines and cable shovels. In addition, the new U60 size of ESCO’s popular Ultralok system, specifically designed for the large quarry market, will be prominently displayed at the event.
