A40, the most used motorway in the Ruhr region of Germany, runs from Straelen, near the Dutch border, over the Rhine and across the Ruhr region to Dortmund. A bridge on the A40 motorway at Junction 28 in Gelsenkirchen-Süd was used to carry A40’s four lanes over B227. A40 is being widened to incorporate six lanes, so the old bridge needed to be demolished. Viersen-based
Prangenberg & Zaum had only two days to complete the demolition, commissioned by Strabag AG in Cologne. “The work went off without a hitch,” says Holger Schmidt, Site Manager at Prangenberg & Zaum. The company chose heavy-duty Atlas Copco hydraulic breakers for demolition work: an HB 7000 with a service weight of 7 tons, an HB 5800 weighing 5.8 tons and an
HB 2500 weighing 2.5 tons. The solid reinforced concrete bridge and bridge heads were removed in only 32 hours. After a pulverizer crushed the demolition waste on-site, the waste was then transferred to Prangenberg & Zaum’s recycling station for further processing. The total volume of the demolition project was 2,300 cubic meters of concrete with steel reinforcement.

“We can make 500 meters of road in a day.”
s India’s economy develops quickly, the country’s infrastructure must develop and grow to keep up. The road and railway network is in need of capacity and quality enhancements; a population of 1.2 billion shares only 600 kilometers of expressways. But change is happening. Jaiprakash Associates, a subsidiary of construction conglomerate Jaypee, is making the country’s second expressway. Named the Yamuna Expressway, it will connect India’s main tourist attraction, the Taj Mahal, with the capital. Today the existing road between Agra and New Delhi is four lanes wide and services all types of traffic, leading to congestion. The new expressway will be six to eight lanes wide and 45 kilometers shorter, paved with Dynapac machines.
Along the road, five new townships are planned. These will be industrial development areas, where companies will receive tax breaks for setting up manufacturing plants, sports complexes, residential apartments and other projects. N.K. Singh at Jaiprakash is responsible for the first third of Yamuna Expressway. He hopes the new road will halve the travel time to two hours. “You can take breakfast in Delhi and lunch in Agra,” he says. Situated roughly 100 kilometers south of Noida, the scenery for a Yamuna Expressway paving site is beautiful, with soft fields and trees.

a rake to get the final details right. The smell of black, shiny, newly laid asphalt is pervasive. Three tandem rollers trail a Dynapac paving machine, flattening the top layer. “They increase the density up to 100%,” explains Gurdeep Singh, Key Accounts Manager at Atlas Copco Road Construction Equipment. The Dynapac paver is used for a width of nine meters, paving two lanes at once. (There is a wider version of the machine as well, which extends 16 meters and can pave four lanes at a time.) Gurdeep Singh says the paver moves at a maximum speed of 3–4 meters per minute. Fed factory-warm asphalt by trucks, the paver distributes the road material in an even layer, guided by a string that stretches between pegs 10 meters apart on the side of the road. “The sensor of the paving machine reads the levels,” explains Gurdeep Singh. The technology ensures the evenness and correct thickness of the layer. The last slick layer of asphalt and the bumpy middle layer, dense bitumen macadam (DBM), are both paved with Dynapac’s machines.
Construction of the road requires raw material, of course, which has to be processed for each layer to be paved. The road is made up of three paved layers, all of which must maintain a certain temperature when fed through the paver. To limit heat loss during travel to the construction site, the factories producing the road material must be located within a radius of 20–30 kilometers. Along the Yamuna Expressway stretch,

Jaypee Group Begun four decades ago in the hydropower sector, the Jaypee Group today is a huge industrial conglomerate with business interests in engineering and construction, power, cement, real estate, hospitality, expressways and sports and education. Jaypee is Atlas Copco’s largest customer in Asia.
Racing to the finish Close to Yamuna Expressway, India’s first Formula 1 circuit hosted its opening race in October 2011. Dynapac pavers were also used for this high-end project. A racing circuit is substantially more challenging to pave than a highway. In highways, the acceptable difference in road thickness is plus/minus six millimeters. In the circuit, the corresponding number is plus/minus two millimeters. The slope is greater as well at 12 degrees, compared with seven degrees in national highways.
The Dynapac paver moves at a maximum speed of 3–4 meters per minute.
four factories had to be built in order to feed the road’s appetite. “We can make 500 meters of road in a day,” says Vipan Kohli, Head of Mechanical at Oriental Constructors, a company that has paved 55 kilometers of the stretch so far. Kohli has noticed a clear difference between his Dynapac paver and other brands. “This is faster than other machines,” he says. The engineering company Era owns 135 million US dollars’ worth of machinery that it rents to other subcontractors. Sandeep Chicra, Equipment Head of the company, has noticed an additional difference. “The service is better with Dynapac machines,” he says.

Throughout his career for Dynapac, Gert Hansson has been sent all over the world. He’s picked up a lot of wisdom – and stories – along the way.
Indiana Jones doesn’t have much on Gert Hansson.
“The first trip I ever made for Dynapac was in 1991, to North Africa” says Hansson, launching into one of his many tales of servicing road machinery in far-flung places. “I was asked to go and upgrade 13 rollers. I was told this would take two weeks and that the rep spoke English.” As it turned out, the representative spoke French only, and Hansson ended up spending six weeks at the place, learning French on the fly. The weather conditions were so hot that he cooled his pillow in the refrigerator. “I was thinking, ‘This is my first trip for Dynapac, so it must be some kind of test.’ But I’m happy to say, the job did get better.” Well, mostly. Except for the time when a friendly worker gave him a drink of water – taken straight out of the closest river. And the time when… Well, let’s just say Hansson has had his share of adventures in the 24 years he has worked for Dynapac, a company now within the Atlas Copco group, especially during six years spent troubleshooting in the Middle East and Africa. In dozens of countries, Hansson earned a reputation not only for technical expertise, but for being able to turn a bad situation into an opportunity. Until 2004, he was based in Sweden and before setting off to do service training abroad, he says, “I always tried to plan months ahead of time, but sometimes things still went wrong.” He recalled the time Dynapac sold a roller to the United
Nations for use in Africa. “I asked my contacts to confirm that the roller had arrived and had cleared customs. They said, ‘Yes, the roller is here, we have it under a tarp.’ So I flew there to see the company doing the maintenance. They took off the tarp, and under it was a wheel loader! I said, ‘Are you serious? This isn’t even Dynapac equipment.’ They said, ‘Can’t you do the training anyway?’ Ultimately, Hansson tracked down the Dynapac roller at the port, so he could conduct the training session with the roller still on a flatbed. During his six years of traveling to Africa and the Middle East, he felt lucky to have good support from the home office in Sweden whenever a problem came up. He also lived by some simple rules that helped smooth the way: Be patient. Eat what the locals eat, because it’s fresher.
In 2004 Hansson left his African adventures behind and moved to Texas, where he now serves as Product Development Manager, Paving and Construction, for Dynapac USA. His travels may be tamer, but they continue apace, with paver demos in Florida one week and overseeing machine repairs in New Mexico the next. His job comes down to what Hansson likes best: “Something new every day.”

Pressured to transfer
Sirios Shipmanagement S.A. equipped Eviacement I with two XA SE 745 machines.
Sekur Holdings, Inc., a ship management company headquartered in Greece, recently improved one of its cement carriers. Named the Queen Arrow II and operating mostly in the Persian Gulf, the ship has a capacity of 10,640 deadweight tons. Until 2009, she used to discharge her bulk cargo mechanically; today the Queen Arrow II uses a pneumatic solution. Equipped with three diesel-driven Atlas Copco XAS 746 portable compressed air machines – two are used, the third is on standby – the ship transfers the cement ashore with compressed air at a pressure of 4–5 bar. This is the ideal pressure setting for the application, as it moves the material quickly without damaging it. “It’s been working successfully according to the parameters set by the design department,” says Petros Nicolopoulos, an engineer at Sekur. Faster discharge times mean more port visits and more money earned, so Sekur isn’t the only ship management company in Greece making this improvement. Sirios Shipmanagement S.A. has outfitted its Eviacement I cement carrier with two XA SE 745 portable compressed air machines, while Naftotrade Shipping and Commercial SA has ordered 14 XAS 746 units over the past few years.

Making the most of emissions legislation In Europe and the United stateS, the construction
industry faces increasingly tougher emissions regulation for diesel engines. New emission standards for nonroad mobile machinery – including portable compressors and generators – are aimed at improving air quality through a significant decrease in the discharges of particulate matter and nitrogen oxides (NOx), 90% and 50% respectively, compared with 2011 levels. The standards have applied since January 2011 for engines above 130 kW; 56–130 kW engines must meet
the requirements in 2012, and 37–56 kW engines must meet the requirements in 2013. In 2014 the next raft of legislation will require particulate matter and NOx levels to be near zero for almost all power categories of diesel engines. The new legislation also requires the use of low-sulfur fuel. While the European Stage IIIB and the equivalent U.S. (Environmental Protection Agency) Tier 4 interim legislation allows for flexibility during the transition phase, equipment manufacturers must develop,
XAS 27: The compact compressor
QAC 1250: A 1-MW generator in a 20-foot container
The XAS 27 compressor – the smallest of Atlas Copco’s portable compressors – is the first in the Atlas Copco Portable Air compressor range powered by a petrol engine. The XAS 27 (27 l/s, 7 bar) is driven by a Honda engine that exceeds existing emissions regulations. Atlas Copco’s new C55 element is driven by the engine, that boasts a V-Belt drive with a belt tensioning rail system. Whether being used for running pneumatic breakers, chippers, hammers or small hand tools, this onetool compressor can handle projects such as demolition, finishing and renovation. Weighing just over 200 kg, the compressor has an undercarriage that makes transport and maneuvering easy, without any heavy lifting.
The new QAC 1250 generator has the same dimensions as the QAC 1000, but there is 25% more power in the box. Its rugged design makes it suitable for nearly any type of application, including temporary power for industrial plants, events, construction sites, mining, refineries and heavy-duty standby power. The QAC 1250 is a dual-frequency unit delivering 1250 kVA/1000 kW of prime power at 50 Hz and 1450 kVA/1150 kW at 60Hz. Its engine setup ensures the best mixture of size, noise level and power performance on a portable/multi-drop unit, at both high altitudes and high temperatures. A built-in engine coolant heater ensures quick and easy startup in cold conditions, and a variable-speed electric cooling fan allows continuous operation in hot desert environments.

integrate and implement new clean engine technology. Atlas Copco has upgraded its entire range of large portable equipment, such as its compressors, generators and rollers. Atlas Copco products have met environmental requirements and improved in other ways. The equipment performs better, operates more economically and is of higher quality. Atlas Copco has opted for a range of clean engine technology solutions; the technical solution applied depends on the engine size and the equipment type. One approach is the NOx Reduction System with Clean Emission Module, using exhaust gas recirculation (EGR) with a particulate filter. These electronically controlled engines only work effectively with an ultra-low-sulfur fuel. EGR reduces the amount of oxygen in the engine’s combustion chamber and cuts the peak combustion temperature, thus lowering the formation of unwanted NOx. This process generates more particulate matter, which is taken care of by the particu-

late filter. (The particulates are subsequently dealt with through an incineration cycle.) Atlas Copco chose this technology for the fuel economy it provides and the fact that it avoids the need for diesel exhaust fluid refills. “Considerable engineering resources were needed to incorporate the new engine design,” explains SvenErik Samuelsson, Manager, Standards and Regulation, Dynapac Compaction Equipment. “The new standards required significant changes to the design of our machines – rollers, pavers and planers. We worked hard to integrate these new technologies into our existing equipment, without affecting performance or size.” However, Samuelsson also points out there is no working around the cost of implementing the legislation; prices have inevitably increased. Atlas Copco has integrated Stage IIIB technologies in its portable compressors without affecting the products’ size or performance. Nicolas Englebert, Product
B4-41/900 booster: Hurricane takes on Tier 4i
M-41/1000: Ready for rigs
Atlas Copco has taken advantage of new regulations (EPA’s Non-road Regulation Tier 4A emission standard) to introduce the Hurricane B4-41/900 booster model, which uses the same proven design concept as the B7-41/1000 booster. Used primarily in drilling applications, the B4-41/900 has several improvments that provide additional flexibility. Lawrence Van der Veeken, Product Manager Boosters, says, “The success of the new B7-41 design concept and the new regulations were the ideal opportunity to also adapt the B4-41 to the new philosophy and extend our booster portfolio.” The B4-41/900 features a Cummins QSB4 engine, a flat base frame, single-point lifting and an optional bolt-on protection frame.
Atlas Copco Hurricane has launched another new booster module, the M-41/1000. Available with flexible volumetric capacities, the M-41 has a small footprint for installation on water well rigs or reverse circulation drill rigs, as well as mobile drill platforms. The M-41 is equipped with the same features as the new B7-41/1000, including a capacity of 2,440 scfm at a maximum discharge of 1000 psi. It also features forklift pockets in the base frame, a remote mount control panel and a digital temperature scanner. “It’s very compact and lightweight, which will give the customer great flexibility,” says Bram Houpeline, General Manager, Atlas Copco Hurricane LLC.

Manager Large Compressors with Atlas Copco, says, “To accommodate for Stage IIIB, we had to build in a new engine, a new cooling system and a new exhaust after-treatment system into our portable compressors.” The solution limits changes to the engine only; this is made possible by a new control module that was introduced for the Stage IIIB compressors. The control module keeps the regeneration process in the diesel particulate filter in the background, which has resulted in lower emissions and efficiency improvements of up to 10%. The new CC722 asphalt roller was the first Dynapac machine to comply with the legislation and has the additional benefit of offering better performance than previous designs. The company’s new soil compactor range offers its own benefits. “Because of the regional differences in the legislation and the fact that ultra lowsulfur fuel is rarely available outside EU/North America, we need to offer the machines with engines with different emission levels,” explains Samuelsson.

CA rollers: engines that consume less
Atlas Copco has introduced its fifth generation of Dynapac CA single-drum vibratory rollers – CA5000, CA6000 and CA6500. The first of their type with cross-mounted engines, the rollers offer easy access for service and maintenance. Available with Stage IIIB engines (prepared for Stage IV) from Deutz that can run on a mix of biodiesel and fossil diesel fuel, the rollers feature a system that minimizes fuel consumption and carbon dioxide emissions. The CA6000D can be equipped with a sustainability package (an rpm management system, biodegradable fill-for-life hydraulic fluid, a 50-hour service kit, an electrical engine block heater and working lights with LED lamps).
HB 4100: Loses weight, adds performance
SD2500CS: Paves and saves on emissions
Atlas Copco’s new HB 4100 hydraulic breaker is a marked improvement over its heavier predecessor, both in terms of performance and efficiency. A lighter breaker also means that a smaller excavator can be used. (With a service weight of 4,100 kilograms, the HB 4100 is suitable for carrier machines of 40–70 tons.) The guide system of the hydraulic breaker was redesigned for more stability and resilience. A new covering for the retaining bar offers more protection, and the service window and the recesses for the lateral swivel threaded connections have been reinforced. It also includes a range of systems and features for enhanced performance: the VibroSilenced system, PowerAdapt, AutoControl, ContiLube TM II, StartSelect and the optional DustProtector.
Dynapac’s new tracked asphalt paver SD2500CS features a water-cooled Cummins QSB 6.7 diesel engine that offers improved performance, lower noise and lower emission levels that satisfy Stage IIIB requirements. To optimize fuel consumption, the unit has a vario-speed drive that automatically adjusts the engine speed with the system load. The paver also features a new fume suction device to safeguard the operator from asphalt fumes. To safeguard the quality of paving, the unit has the Safe Impact System as well as the Integrated Leveling System. Service is made simple by an effective design that concentrates all the pumps on one side. The fuel tank capacity is 315 liters, maximizing the intervals for refilling.

During 2011, Dynapac was certified according to the health and safety assessment management system OHSAS 18001.
Power to the people
A 15-degree solution Atlas Copco has launched six new hydraulic compactors whose housing attachment is offset at 15° – a design that improves force distribution on the vibrator plate while reducing stress and wear on the compactor. Designed for use on carriers with an operating weight of maximum 40 metric tons, the attachments are used for compacting trenches, ground soil
and embankments as well as for driving in and pulling out formwork, posts and sheet piling. These compactors are virtually maintenance-free, thanks to the PermanentLube continuous lubrication system. The integrated flow rate and pressure control protects the units from overload, particularly if the compactors are used on different carriers.
The new power pack lines LP 9-20 P and LP 9-20 E boast improved cooling capacity and full component protection. Providing a hydraulic flow of 20 lpm and a pressure up to 150 bar, they are an ideal portable power source for hydraulic tools such as breakers, saws, pumps, core drills and post drivers. The power packs have a number of features for easy and safe operation. Tool changes are faster and safer thanks to a built-in on/off valve and flatface quick-release couplings. Petrol versions of the packs feature standard Power On Demand, and electric versions have a built-in phase switch and a motor protection relay. The new lines also include a refined oil filtration system, large spinon filter, a built-in bypass protection, thermostatic oil temperature control and a direct-mounted hydraulic filter gauge.

Thanks to their new angled shape, two new Atlas Copco BP Bulk Pulverizers are ideal for secondary demolition and additional reduction of reinforced concrete. Available for carriers of 18–35 tons, the pulverizers have huge, broad jaws that make it easy to grab material on the ground. They cleanly separate out rebar and reduce concrete into grain sizes suitable for crushing or use as backfill. An optional hydraulic rotation device makes it possible to use the pulverizers for primary demolition as well. Constant high power at the jaw tips. demolishes more structure per bite, and speed valves shorten the opening and closing cycle times, thus lowering fuel consumption.
