Despite volcanic ash and grounded flights, the mood in Munich was upbeat, and the show boasted a record number of exhibitors.
By Therese Dunphy, Editor in Chief
The show must go on. It was a rallying cry throughout Munich this spring as Iceland’s volcanic activity prevented many international visitors from attending the trade fair. Despite a ban on air travel during the opening days of the show, more than 415,000 visitors from over 200 countries attended Bauma 2010. Nearly two-thirds of visitors came from Germany, while the remainder was comprised of international travelers. Those who made it to Munich noted an upbeat mood among both the exhibitors and attendees. “The mood in the industry shows that, in Europe, the bottom of the cycle is now behind us. Confidence has returned,” said Ralf Wezel, secretary-general of CECE, the Committee for European Construction Equipment, in a show press release. “Of course at the start of the fair, the exhibitors felt the lack of many customers from Asia and America — but in the second half of Bauma, this improved considerably.”
Although a number of the events to be held in the first two days of the show had to be cancelled or re-staffed, approximately 44 lectures and events took place as scheduled from the third day on. And, as could be expected, numerous product introductions and updates debuted.
The next iteration of the show, the 30th Bauma, will be held April 15-21, 2013, in Munich. AM
Atlas Copco launched new and modified underground rock drills and stoppers, including a line of silenced light rock drills for underground applications. To address sound emission, the sound power levels of several drills were reduced by 5 to 8 dB(A), a reduction of more than 50 percent to the human ear. The BBC 34 WS6 and BBC 34 WS8 are new heavy-duty stoppers added to Atlas Copco’s existing range and are designed for tough working conditions in drilling, raise driving, and bolting applications. Suitable for medium- to hard-rock, they benefit from a high impact energy blow and a strong rotation mechanism.
Atlas Copco introduced three new hydraulic breakers with PowerAdapt and optimized power-to-weight ratio. The HB 2000, with a service weight of 2,000 kilograms, offers 10 percent more power than its predecessor, the HB 200. The new HB 3100 and HB 4700 deliver 5 and 13 percent more power than their respective predecessor models. By developing and building attachments with an improved power-to-weight ratio, the company says the same performance can be achieved with a smaller attachment and carrier unit, thereby reducing capital and maintenance costs. An improved guide system is said to improve stability while a new retaining bar provides additional protection in the lower part of the hydraulic breaker, which is subject to greater wear and tear.
Caterpillar unveiled an updated version of its popular 988H wheel loader. The unit blends its predecessor’s top qualities with a fuel efficiency increase of up to 10 percent. Features include the C18 ACERT engine, 555 gross horsepower, a 12.5-ton payload, and bucket sizes ranging from 8.2 to 10.0 cubic yards. The Positive Flow Control hydraulic system uses a new electronically managed, variable-displacement pump that works with an integrated solenoid valve with force feedback to manage oil flow. A fuel management system, auto idle kickdown, and idle shutdown are among the fuel-saving features of the updated machine. Laminated windows have two panes of glass separated by an air gap to dampen window vibration, and interior sound levels are reduced by 1 dB(A).
Sandvik unveiled its SC screen, an inclined screen with circular motion and modular deck design. The flexible deck configuration allows the use of various screening media types and streamlines changes. The mechanism can be removed from the screen body as a single unit for ease of maintenance. Commonly sized rubber modules are used in feed and discharge areas, and the units can be modified to allow installation of water spraying devices.
Leica Geosystems showcased its Jigsaw 350 Mine Management Solution, designed to increase productivity, reduce costs, and enhance safety standards. It uses advanced technologies to automatically provide optimized truck and shovel assignments, increase productivity, monitor and report key performance indicators, and minimize operating costs.
Godwin Pumps marked its 40th anniversary with the introduction of two new pumps, the HL260M and CD500M Dri-Prime Pumps. The first pump is a 10-inch by 8-inch automatic priming pump that offers solids handling up to 2 inches in diameter and maximum flows of 4,760 gallons per minute. The larger unit is 24 inches by 18 inches and can handle solids up to 4 inches in diameter with flow rates up to 13,500 gallons per minute.
Cummins Inc. debuted the QSX11.9 and QSX15 Heavy-Duty engine duo featuring its proprietary Xtra-High Pressure Injection fuel system and a variable geometry turbocharger. The 11.9-liter and 15-liter QSX are supplied as fully integrated air-intake-to-exhaust aftertreatment systems to meet 2011 EPA Tier 4 Interim and EU Stage IIIB regulations. The engines use a Cummins Particulate Filter to reduce particulate matter emissions by more than 90 percent and a cooled exhaust gas recirculation (EGR) system to reduce NOx emissions by 45 percent. The engines are said to lower operating costs with up to 5 percent improved fuel efficiency compared with Tier 3, depending on the duty cycle.
Truck body extends life, lowers costs
Caterpillar developed a new hardened steel Quarry Body for the Cat 770, 772, and 775F rigid-frame trucks to extend wear life and decrease cost per ton in appropriate applications. The truck body features 400 Brinnell steel, which resists abrasion and provides superior durability without additional weight or liner systems. It is designed to handle low- to medium-density materials that have low to medium abrasiveness, including limestone, some sandstones, and slate. The Quarry Body is ideally suited for limestone quarries where oversize stone is no larger than 2 to 3 feet in diameter. Its flat floor configuration allows the operator to meter loads when feeding crushers and retains the load well when hauling on roads with grades in the 8- to 12-percent range.
Portable crusher line
Hartl Powercrusher presented its new Powercrusher Series of track-mounted crushers. The mid-size PC3 and PC4 and large PC5 and PC6 units are suitable for processing of virgin aggregates. The PC3 is an impact crusher, while the PC4 is a similarly sized jaw crusher. Both feature low total weight and quick set-up — in less than 30 minutes — and can process up to 300 tons per hour, depending on material and feed size. The PC5 is a larger impact crusher and the PC6 is the equivalent jaw. The units offer a double-deck, independent, heavy-duty grizzly section before the materials enter the crushing chamber. The units can produce up to 400 tons per hour.
Liebherr exhibited the R 9100 mining excavator, a new 100-ton unit powered by a new Liebherr V12 diesel engine. With a rated power output of 757 horsepower, the engine — together with the hydraulic system — supplies high breakout and digging forces for day-to-day operation. The 6.8-cubic-meter bucket is designed for mining, with a design for improved penetration and high fill factor. The cab boasts a raised operator’s seat with large, panoramic windows and two cameras feeding a 10.5-inch display screen. The prototypes are undergoing factory and field testing.
John Deere Power Systems (JDPS) displayed its entire Interim Tier 4/Stage III B diesel engine lineup and announced engine models and power ranges at Bauma. For engines 56kW (75 horsepower) and above, John Deere will use its PowerTech Plus Tier 3/Stage III A in-line, four- and six-cylinder engine platform — which includes cooled exhaust gas recirculation (EGR) for NOx control — and add an exhaust filter for reducing particulate matter (PM). Engines between 56 kW and 129 kW (173 horsepower) will be available in 4.5L and 6.8L displacements and will be equipped with either a wastegate or variable geometry turbocharger, depending on engine size. Engine models 130 kW (174 horsepower) and above include the 6.8L, 9.0L, and 13.5L displacements. John Deere opted not to use selective catalytic reduction (SCR), and noted that it believes its cooled EGR and exhaust filter approach provides OEMs and end-users with “a proven solution with the best total fluid economy.”
After a number of evolutionary changes, Liebherr has christened its new 400-ton payload truck, the T 282 C. The successor to the company’s T 282 B, the unit features a new cast frame, axle box, and cab, as well as a drive system designed and built by Liebherr. Engine options include the MTU DD 20V4000 or the Cummins QSK 78. Its top speed is 40 miles per hour.
Volvo Construction Equipment featured its OptiShift driveline system designed to optimize fuel savings by up to 15 percent. OptiShift includes a new torque converter with lock up and free wheel stator, as well as Volvo’s patented reverse by braking function. It will be rolled out across Volvo’s L150F, L180F, and L220F wheel loaders. Some of OptiShift’s benefits include faster loading cycles, increased operator comfort, better drive response, increased hill climbing performance, better deceleration comfort, and less loading stress on the torque converter and transmission.
New backhoe loader generation
JCB unveiled a new generation of backhoe loaders that are said to offer average fuel savings ranging from 6 to 16 percent at typical daily work rates. The fuel efficiency is largely achieved through the introduction of a new EcoDig system that incorporates three hydraulic pumps. The loaders feature a re-styled counterweight and vertical grille design, as well as a sloping hood that improves forward visibility. Other improvements include a more comfortable cab and power brakes that provide proportional braking and fuel economy improvements.
