Most editors enjoy the shows but then comes the dilemma of trying to keep on top of publication deadlines and deciding what to feature, where to give precedence, etc. These are objective decisions but given the plethora of new products - especially at an event such as Bauma 2013, it is never easy.

Trade Show Season Soon To Kick Off In many respects editors have mixed emotions at the beginning of each year as there is the excitement of visiting trade show after trade show to see new machines being introduced. However, these are very time consuming and, even with modern technology, writing on the road is not that practical - a day walking the floor is very tiring. And, the combination of increasing age and shows getting larger is not a good one!

Most editors are also under extreme restrictions on the number of pages that they can have for editorial pages. Unlike digital publications such as Contractors World magazines which are not constrained by print and distribution costs, printed magazines have to be more careful and are very dependent upon the number of pages of advertising. All that aside. Contractors World magazines will be reporting on all the major trade shows and giving in-depth reviews of as much of the new equipment as possible. This may be spread over a number of issues to ‘ease the load’. I have to do this, as I still need to include features on site reports and other activities within the industry - worldwide. Not everyone is interested in reading page after page on new equipment. In fact, I suspect that many of our readers prefer to read of machines proving themselves on site. The highlight of 2013 for Contractors World Magazines will be Bauma 2013, with the first previews in January and subsequent editorials in every issue until the middle of the year. Probably the most in-depth coverage of any magazine printed or digital.

New Features for 2013 As readership of Contractors World magazines continue to increase so we need to give more focused editorial to specific sectors. Within the issue there is a special supplement called ‘FORMWORK & FALSEWORK’. From February 2013 this will be published as a separate publication supplementary to the main magazine. It will be published quarterly and cover all aspects of the sector involving formwork and falsework. This will include scaffolding, shoring, bridge launching systems and concrete placement.

Panorama France New underpass to relieve congestion The Terres Saint Jean business and shopping park in Épinal, which was built in 2006, has grown considerably over the years to become one of the largest commercial locations in Eastern France. This has resulted in a significant increase in traffic, in particular at the crossroads over the RN57 main highway between Nancy and Besançon. Major works to renew the infrastructure, improve traffic flow and safety at the junction with the RN 57, started in March 2012. This included the construction of an underground passage under the RN 57 linking the two parts of the Terres Saint Jean business and shopping park, making them more readily accessible. The client, Épinal town council, assigned this part of the €1.5 million development project to Peduzzi TP. The company which is managed by Philippe Vuillemin, was founded in 1880, and specialized in construction, before branching out into earthworks in recent years. At Épinal, the contractor was faced with a complex, major earthworks and roadworks project that lasted almost 6 months. The job was made more complicated by the different levels of the new access ways, and in particular the passage under the RN57. They also had to deal with the 20,000 m² of various materials that had to be carefully excavated, due to existing utilities. Philippe Vuillemin, took up the challenge by purchasing two new CX series excavators - a CX250C and CX350C. “I have remained loyal to Case for many years. These machines are very reliable, modern and efficient. I have been using a CX330 for more than 6 years. It has more than 6,000 hours on the clock and has never needed repairing. The new CX series C excavators lived up to all our expectations,” explains Philippe Vuillemin.

Panorama Singapore 3 luffers at the Art Gallery 2015 will see the opening of the new National Art Gallery in Singapore, which will be the region’s biggest museum, at 60,000 m². Two adjacent buildings at Singapore’s Downtown Core, the City Hall and the former Supreme Court, will be transformed to host a large collection of Southeast Asian art. This institution will contribute to building Singapore as a regional and international hub for visual arts. Takenaka - Singapore Piling Joint Venture has been appointed as the main construction contractor for the works, with an estimated budget of US$420 million. These two historic buildings, both national monuments, will undergo conservation and adaptive reuse to transform them into the new Gallery. To carry out these works, the consortium relies on three LCL 500 luffing-jib cranes from Linden Comansa, with maximum load capacity of 24 tonnes and height under hook of 38.5 meters, which are part of the rental fleet of Linden Comansa’s official dealer, Access Systems Technology. The main functions vary from loading and unloading materials, concrete casting and shifting of heavy materials and equipment within the site. Two of the cranes have been erected with jib length of 55 meters, which allows them to load up to 7,900 kg at the jib end. The third crane has a jib length of 65 meters, the maximum of this model, and can load up to 4,700 kg at the jib end.

Australia Infrastructure project in Brisbane Legacy Way (formerly Northern Link) is a major road tunnel project in Brisbane. From 2014 on, two parallel road tunnels, approximately 4.6 km long, will connect the Western Freeway in Toowong with the Inner City Bypass (ICB) at Kelvin Grove. BAUER Foundations Australia Pty Ltd, was awarded the piling works for the eastern cut-and-cover structure, as well as vent shafts and the western trough. The scope of work for stage one comprises the construction of approximately 590 secant piles, 111 soldier piles and bored piles with 900 and 1,200 mm diameters up to 28.5 m in depth. Bauer BG 25 and BG 28 drilling rigs were used as main equipment, employing segmental double wall casing installation technique. Particularly challenging was the work from an existing flyover at the Inner Northern Bus Way which needed to be modified to suit the future Legacy Way road alignment. The other main challenge faced on site was to overcome the unexpected extreme high strength rock, up to 160 MPa. The project duration is split into two stages. Stage one was completed in September 2012.

Panorama Australia Success with site dumper rentals TWS Hire, “The Watercart Specialist”, in New South Wales operates a large fleet of car licence, self-drive watercarts, typically hired out to construction companies for dust suppression on road works, excavation and construction sites. The company supplies the greater Sydney region from Grafton on the far north coast down to Wollongong and the south coast of New South Wales “We noticed that many contractors had a need for moving material on difficult construction sites. These tasks involved steep slopes, sandy ground or other surfaces that aren’t suited to road trucks, or sites that other vehicles find too challenging,” said TWS Hire’s general manager, Billy Bastian. “Just over three years ago, we acquired our first Terex TA6 site dumpers. It soon became apparent that our customers had applications that demanded swivel dumpers, so we have added four Terex TA6S swivel dumpers to our hire fleet. “Many of our customers need a six-tonne dumper because their jobs are becoming more difficult for road trucks to access. With conditional registration, the vehicles can cross or work on roads. Whether carting broken road base, concrete or backfill, their four wheel drive and large footprint tyres with all-terrain tread is a huge asset, particularly on sloping sites. There are very few places where these dumpers cannot operate.

France JCB long boom in search for WWII bomber A JS360LR (long reach) crawler excavator produced by JCB has played a key role in the excavation of remains of a WWII Lancaster Bomber, which was shot down in Normandy on D-Day, June 6, 1944. Use of the machine, owned by French rental company and contractor, Christophe Beaussire, was donated along with a JS220 and a JS240, a Loadall telescopic handler and a JCB Fastrac tractor to complete the delicate excavation work. The site of the plane crash was found by British aviation archaeologist and historian Tony Graves. Mr Graves obtained permission to excavate the site from the farmer and from the French Government. By using the extended digging depth of the JS360LR long reach machine, the company has been able to carefully excavate the site, without having to track the heavy excavators into the soft ground in the excavation area. The dig revealed hundreds of twisted parts that have been identified as coming from the Mk II Lancaster Bomber, along with its Merlin engines, the 300 rounds of ammunition, propeller blades and wheel hubs.

Panorama Kenya BSP hammer driving piles for port expansion Construction work on Kenya’s largest and busiest seaport at Mombasa is well underway to expand the existing facilities and build the new Berth 19 which is expected to be completed early next year. In addition the port will be dredged of mud and silt to accommodate larger ships. Dredging and construction of the new berth and extension of the existing facilities commenced in June last year with dredging scheduled to be completed at the end of this year. Dutch-based Van Ord Dredging won the dredging contract. The two projects are being funded by the Kenyan Government and will, cost in excess of £71 million. Dredging alone will cost nearly £39 million. China Road and Bridge Corporation (CRBC) won the contract to construct Berth 19 and associated works. To drive the piles required for the berth’s foundations the company purchased a BSP International Foundations (BSP) piling hammer and power pack through their Chinese dealer, Shanghai Trust Machinery. The CG240 hammer with a dropweight of 16 t and powered by a BSP HP250 power pack was used to drive approximately 300 tubular steel piles, 813 mm in diameter, a wall thickness of 16 mm and ranging in length from 20 m to 36 m. Each pile is designed to take a bearing load of 240 t. The CG range of BSP’s heavy-duty impact piling hammers offers dropweights from 12 t up to 40 t. They are designed for driving a variety of bearing piles including steel tube, combi piles, H-sections and reinforced/prestressed concrete piles and can be operated from piling rig leaders or crane suspended. A choice of three Hydro Packs is available which are powered by either turbocharged Perkins or Caterpillar diesel engines developing 71 kW up to 250 kW. These units have been specifically developed by the company to maximise the performance of its piling hammers. The existing container terminal berths at Mombasa were designed to accommodate ships 180 m long but most now calling at the Port today measure 230 m. The three container berths have a total length of 600 m and are being extended to 760 m which will allow three vessels each with a length of 235 m, leaving a 215 m safety allowance.

Germany New LTC 1045-3.1 proves its capabilities in hall applications Space is tight between the dozens of gear machining units at the Liebherr-Components Biberach GmbH production site manufacturing large slewing bearings. Exactly the right kind of application for the compact Liebherr LTC 10453.1 telescopic crane. During the assembly of a new Liebherr gear cutting machine, the crane was used multiple times for lifting the individual components into place. In mid-October, the 4.2 tonne cutter head was raised into position for assembly onto the main column on the new machine. The counter-column was then lifted into place onto the machine bed. In this process, the LTC 1045-3.1 was required to position a load of 10 tonnes onto a highprecision guide track with exceptional accuracy. The new Liebherr LC 2000 gear cutting machine can machine gears up to a diameter of 2 m, where tolerances of just a few thousandths of a millimetre are critical. Crane rental company ESB, based in Mittelbiberach, Germany, took delivery of a new LTC 1045-3.1 in their Ehingen production plant in April of this year and since then have already had to handle several crane operations where the compact design and manoeuvrability of the 45 tonne crane were very much required.

Aquajet Aquacutter strips decayed concrete on Haifa pier Specialist marine contractor, Maagan Marine & Diving Works Ltd, is using hydrodemolition techniques to remove decayed concrete from the East Pier at the Port of Haifa, during a three-year project to rebuild the pier. The key piece of equipment is an Aqua Cutter 710V Evolution from Sweden’s Aquajet Systems AB. Compared with traditional operation using jackhammers, the Aqua Cutter is able to replace between four and five hammers during a single shift, and also leaves a cleaner finish on the rebar of the pier; which is being left in situ for the reconstruction. Maagan Marine’s chief executive officer Avi Ben-David says that no jackhammers are being used and that the Aqua Cutter has increased accuracy and productivity while reducing manpower and the risk of ‘white finger’ from vibration for the operators. “We consider ourselves an innovative company, and we always seek to find, incorporate, and deploy new technologies which allow us not just to meet our goals, but to exceed them,” he says. “We have found the Aqua Cutter robot a good solution both to the project requirements and to the tight schedule, and it has allowed us to reduce the planned time frame.”

Major seaport The Port of Haifa is the second largest of Israel’s three major international seaports, a natural deepwater harbour that operates all year long, serving both passenger and merchant shipping. It is one of the largest ports in the eastern Mediterranean in terms of freight volume and handles over 22 million tons of cargo each year. The East Pier was originally built at 1979 to a length of 686.5 m. During 1994, due to high levels of corrosion the pier was treated with epoxy paint. It was also extended by 277.5 m, taking it to a length of 964 m Page 10

Contractors World - International Vol 3 No 9

With a height of 2.7 m, the approximate working area for Maagan Marine is 2,602.8 m². “Due to the age of the pier, and the wear and tear it has undergone, the condition of the concrete was deteriorating to the point that the rebar was showing through in some places,” says Mr David. “ T h e Po r t A u t h o r i t y d e c i d e d o n a re n ovat i o n o f t h e p i e r, a n d we we re contracted to remove the old concrete and undertake the renovation. “The removal of the old concrete requires some precise removal work, because the rebar itself is still in good condition and will form the basis of the new construction and concrete work.” The tidal level at the pier is around ± 0.5 m, but as the pier was initially built at maximum tidal level, there is no underwater work involved. Mr David says that the hydrodemolition operation takes place for between six and seven hours per day, six days per week, and this will be consistent for the duration of the whole project, which was originally set for a three-year period but will be significantly reduced.” “A typical shift is about 10 hours, and we are using the robot for two-thirds of this time,” he says. “We are handling an area of about 8 m² per shift, to a working depth of 17 cm, and had we been using jackhammers we would have needed four or five of them working simultaneously to achieve this kind of progress. “Our operators are also very happy with the machine, they are very positive indeed with using the robot and they are highly pleased with the quality of the work they are delivering.” Equipped on this project with a hydraulically operated extension kit, the machine does not carry any towers or have any protruding arms. Mr David says that the concrete being worked on is type B40, with the existing rebar within the pier of type ST 37. “The existing rebar was found to be in good condition and therefore it will not be replaced,” says Mr David.

Construction projects reliant on massive volumes of concrete, in countries such as Singapore, where the temperature is mostly above 24Âş C, have to take special precautions to manage the concrete to ensure that structural integrity is maintained.

Construction looks to Temperature Control Solutions by Alan Loudon, Head of Temperature Control, Aggreko plc


emperature, whether it be searing heat or freezing cold, is a force impacting the construction industry across the globe. Not only is health and safety at risk in extreme temperatures, but so is the integrity of the build project – excessively high or low temperatures will mean that concrete will not set correctly and the construction becomes prone to cracking. Organisations such as Aggreko, leading provider of temporary power and temperature control services, can Page 12

Contractors World - International Vol 3 No 9

assist construction companies from the project planning stages until project completion to make sure that heat or cold is not a worry for any project.

Concrete cooling Temperature control is becoming recognised as an essential technical element for the construction industry. Concrete must be produced between 8º and 12º Celsius in order to ensure that it sets properly as temperatures higher than this can cause the concrete to crumble and crack once set. Chemical additives are also commonly used throughout summer months, to counteract the normal exothermic reaction as well as the effects of additional climatic heat. However, chemicals alone are unlikely to keep the concrete mix at the necessary temperatures. A common solution is for the company to purchase an ice plant, which is installed between the water tank and the mixer and ensures that water running through the plant is cooled sufficiently to keep the concrete mix at optimum consistency. An ice plant, however, is an expensive investment and requires regular maintenance from expert technicians. Should there be a failure of the machinery, production will be stagnant until it can be repaired, which may mean waiting for essential parts. In addition, ice plants are expensive to run, with large fuel costs to consider. One way to avoid this potentially financially damaging problem is to have temporary temperature control installed. Temporary water chillers and air conditioners can be invaluable tools for the construction industry and provide crucial assistance throughout the summer months. One application that is regularly practised on site is the use of chilled water coolers for concrete batching. In order to reduce the stress caused to concrete being produced at temperatures above 12º C, cooled concrete can be produced through the use of chilled water or ice in the blending stages. Globally, contractors are becoming increasingly aware of the benefits of hiring from temperature control specialists equipped to provide support during time sensitive fit-outs.

World leader Aggreko plc, is the world leader in the supply of power and temperature control solutions to customers who need them either very quickly, or for a short or indeterminate length of time. Examples would be the supply of power to an industrial site which needs to service its permanent power supply, supplying a whole city in times of power shortage, or providing a major sporting event with power and cooling systems. Recent customers include: • London 2012 Olympic Games, • 2008 Beijing Olympic Games, • The Vancouver 2010 Olympic Winter Games Other customers include the power utilities in over 50 countries including the UK, France, Angola, Kenya, Indonesia, Bangladesh, Venezuela, Chile, Brazil and the USA.

Contractors World - International Vol 3 No 9

Page 13

Should a construction company decide to install their own ice plant, however, they may require additional power to ensure the smooth running of operations, especially in remote locations or areas where power outages are common. In cases such as this, the services of a temporary power provider are often employed until the project is completed.

Fast-track fit-outs A large percentage of construction occurs in areas with growing populations that put pressure on utility infrastructure. This means that a series of large and time sensitive construction projects almost inevitably occur in regions where the local utility company is already stretched to the limit, often resulting in long delays when it comes time to connect the buildings to the utility grid. Such delays can be due to the fact that in a warm climate, it is difficult to grout or paint the interior of a building without sufficient air conditioning, as the high temperatures can cause the materials to dry too quickly and crack. By using temperature control equipment, developers can fast-track the fit-out stage of a construction project by using de-humidifiers and air conditioners to create a cool and dry atmosphere. Globally, contractors are becoming increasingly aware of the benefits of hiring from temperature control specialists equipped to provide support during time sensitive fit-outs.

Comfort cooling for health and safety During the foundation stages of construction projects, personnel can often be working either underground or in confined and badly ventilated environments. During the summer months, the use of heavy machinery in such environments can cause the temperature to rise to dangerously high levels, creating uncomfortable and unsafe working conditions. Employing the services of specialised temperature control organisations helps to create safe and comfortable working environments for personnel and also demonstrates an organisation’s commitment to the well-being of their workforce as well as to industry legislation and standards. Construction companies around the world acknowledge that safe and comfortable conditions for their workforce largely equates to increased morale, concentration and productivity. Therefore, ensuring projects are completed safely, on schedule and within budget and minimising down time due to accidents is critical to overall success.

An essential on-site tool With improved health and safety legislation, communicating to co nt ra c to rs t h e i m p o r ta n c e o f temperature control for safe and comfortable working conditions for personnel, construction organisations globally are beginning to recognise the benefits that investing in these

Page 14

Contractors World - International Vol 3 No 9


facilities can bring. Improving productivity, increasing the likelihood of completing projects on schedule and ultimately having a positive impact on costs are just some of the benefits that can be reaped by contractors. The technical uses for temperature control are also becoming commonplace on the construction site. With contractors employing the services of temporary temperature control specialists for applications including chilled water for concrete mixing and cooling individual buildings for fit-outs, the applications of temperature control are varied and important, but all serve to ultimately lower costs and to fast-track the successful and on-schedule building of construction projects. Although just one tool among many for the construction industry, temperature control is nonethe-less a necessary element throughout the lifecycle of a project. From chilled water for concrete mixing, to comfort cooling for individual rooms, to cooling of entire building developments, the applications of temperature control are varied and important, serving to lower costs and to fast-track the building of massive projects.

Caterpillar and their Turkish dealer, Borusun, recently put together an impressive demonstration of how the various pieces of Cat equipment can be used to create a fully integrated work tool for construction activities. Apart from a well orchestrated live demonstration simulating the building of an access road in a housing estate, the thousands of people attending where then able to walk around the ‘show village’ where specialists from the various divisions of Caterpillar were on hand to discuss further the solutions available. These ranged from financing through to remanufacturing and technology. A vast array of machines were also on display; mostly in operational condition enabling customers to operate and evaluate the various features. Damien Giraud, Global Construction and infrastructure - marketing manager (below) said “We have developed a special program for customers from across EAME to discover our latest products, technologies and solutions for serving customer needs in your construction business. Customers are central when Caterpillar designs products and services and we hope that the experience of the Cat Construction days in Antalya is inspiring, educational and recreative to all.”

Postcard Caterpillar Construction Days 2013 - Antalya


ver a period of 3 days in October, more than 1,000 guests of Caterpillar with 26 dealers from Africa, Middle East, CIS/ Russia attended a series of presentation detailing the many solutions that Caterpillar and Cat equipment make available today. The various solutions are like a series of building blocks which can be linked together to provide the most cost efficient and most productive solution to best meet different challenges.

Contractors World - International Vol 3 No 9

Page 17

Building blocks can be put together in different configurations to best meet the needs of plant hire companies, owner operators, specialist sub contractors through to the largest contractors, quarrying and mining operation. There are solution ‘blocks’ for financing; for maximising the use of technology to reduce project times and fleet management costs; attachments, servicing, special needs, attachments, rental, and used equipment. The working demonstrations were more than a simple parade of machines but were actually used to build embankments, an access road and a roundabout typical of those found in a new housing development. The demonstrations also highlighted issues such as ensuring prior knowledge of underground utilities before excavating, the right way to do things and the best way to do it. Thereby avoiding trouble shooting, make good and repeat working. As the list of equipment on display showed, there is little from the Caterpillar construction product line that was not there or represented by part of the range. It would make for an impressive display if Caterpillar was ever able to put together a full display of every model of every machine they produce. Given the recent advances in mining equipment, etc. such is virtually impossible to do give the size of the range of equipment available. Contractors World enjoyed their time watching, listening and discussing with various people and, although there was nothing new, if you ever get the opportunity to attend a Caterpillar Construction Day, it will be time well spent.

New Komatsu D61-23 Crawler Dozers


17,780 – 18,660 kg new line of D61-23 crawler dozers powered by Operating weight 126 kW S3B engine technology has been introduced Engine power (ISO 14396) 3.4 – 3.8 m³ by Komatsu Europe. Based on customer Blade capacity 3165 mm feedback, and using the popular design of the D51-22 Track-on-ground length as a starting point, Komatsu has refined the D61-23 to Max. Speed 9 km/h make it technologically smarter and with a claimed up Specifications are for guidance only and are subject to to 20% reduction in fuel consumption depending on change according to machine configuration application and working mode. Komatsu say that the machine has been designed to lower costs for operations and ownership while increasing productivity. New longer track-on-ground standard (EX) and low ground pressure (PX) models are available to offer customers flotation and weight distribution options that best match their applications. Operating weight ranges from 17,780 kg to 18,660 kg depending on the configuration. The new models push with a net of 125 kW / 168 HP at 2200 rpm (ISO 9249 / SAE J1349). Developed as a versatile multi-tool, the latest dozer is designed for a wide variety of applications, including land clearing, grading, forestry and site work. A full guarding package and other attachments are available for easy customizing to meet specific customer requirements.

EU stage IIIB / EPA Tier 4 Interim (S3B) emission certified engine Built upon proven Komatsu Tier 3 technology, the S3B SAA6D107E-2 engine provides the same horsepower as its predecessor but lowers fuel consumption by up to 10%. Komatsu’s S3B engine platform uses an advanced electronic control system to manage airflow rate, fuel injection, combustion parameters, and after-treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability. The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that doesn’t interfere with daily operation and keeps the operator aware of its status. This smart and simplified system removes soot using “passive regeneration” the majority of the time, to minimize “active regeneration” events. For owners, this means lower fuel costs because of fewer active regeneration events as well as seamless operation for the operator. As a leader in hydraulic technology, Komatsu also developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision and air Contractors World - International Vol 3 No 9

management as well as longer component life due to less moving parts and reduced component complexity.

Unrivalled blade visibility and ride The steeply sloped engine hood and new forward cab design provide more room for operators while moving them closer to the blade, for improved blade visibility, ride quality and overall comfort. The cab has an integrated ROPS / FOPS structure and is designed with large glass windows for better visibility. Internal cab air pressure and air filters minimize dust entering the cab, and viscous cab damper mounts suppress noise and vibration when travelling over rough terrain.

New durable and productive power angle tilt (PAT) blade A newly designed PAT blade with a highly durable box structure and good curvature rolls material efficiently, to improve productivity. The new standard adjustable blade pitch allows the operator to adjust the aggressiveness of the cutting edge for varying applications. The new hydraulic blade angle toggle switch improves ease of blade operation. Enhanced Plug & Play provision for Topcon is standard; only a simple bolt-on completing kit is required for the quick and easy installation of Topcon 2D/3D systems. Standard rear hydraulics for the ripper are also included for increased machine versatility.

Next generation HST transmission and engine control technology Two selectable Working Modes – E and P – match machine performance to the application. E Mode is intended for all general dozing, levelling and spreading applications providing adequate speed and power while saving fuel. P Mode is intended for slot dozing, ripping, uphill dozing or other applications that require maximum power where engine power has priority over fuel consumption. The D61-23 incorporates new proprietary engine and hydrostatic transmission pump control technology to improve operational efficiency and reduce fuel consumption to levels lower than a conventional HST control system can obtain. This Komatsu exclusive feature reduces fuel consumption by up to 10% in P mode in demanding working conditions and up to 20% in E mode under lighter load conditions as compared to the prior model. Powerful turns under various work conditions are achieved with the new HST transmission, even under load. Counter-rotation is available for minimum turning radius, providing excellent manoeuvrability in tight spots. There are two gearshift modes: Variable and the new Customizable Quick shift. Variable shift mode provides 20 incremental speed settings for the operator, while the new Customizable Quick shift provides 3 speed settings; all can be adjusted in the monitor to obtain the right speed for different operator preferences.

Newly designed joystick controls for power and comfort Komatsu’s ergonomically designed Palm Command Control System (PCCS) gives operators maximum control, offering a relaxed posture and superb fine control to minimize operator fatigue. Thumb push buttons simplify transmission speed setting shifts shown graphically in the monitor. The travel lever turning sensitivity can now be easily adjusted in the monitor to better match operator preferences. The new blade electro-hydraulic controls incorporate a new blade angle switch and float switch. The blade feel can also be adjusted in the monitor to best match operator preference Page 20

New cab design improves operator environment The new crawler dozer’s comfortable working environment allows operators to concentrate on the work at hand for increased productivity. The interior cab decibel level has been decreased to 78 dB for a quieter work environment. A comfortable standard air ride seat with heating enhances operator comfort further. A standard rear view monitoring system can be synchronized with reverse operation. A new version of the large 7� high-resolution LCD colour monitor in the cab displays all machine information. An easy to use tab system allows operators to select the parameters they want to see and also provides quick troubleshooting for a service technician with easy to use on-board diagnostics.

Convenient maintenance equals reliability Recognizing that maintenance is critical for successful equipment uptime, Komatsu has designed the D6123 with easy routine maintenance in mind. Daily engine checks are grouped at the left hand side of the engine compartment. The rear mounted swing-up reversible electronically-controlled hydraulic fan allows for easy checking of the radiator, oil cooler and charge air cooler. A manually reversing fan allows for quick cleaning of the radiator. It also comes standard with the Parallel Link Undercarriage System (PLUS). This rotary bushing system doubles the undercarriage life compared to prior conventional systems, significantly lowering owning and operating costs.

Komatsu CARE and KOMTRAX It is supported by Komatsu CARE, a complimentary maintenance program for Komatsu customers that comes as standard with every new Komatsu S3B construction machine. For the first three years or 2.000 hours it covers factory scheduled maintenance, performed by Komatsu-trained technicians with Komatsu Genuine parts. Komatsu CARE offers up to a maximum of 2 complimentary Komatsu Diesel Particulate Filter (KDPF) exchanges and a KDPF warranty for the first 5 years or 9.000 hours. The latest KOMTRAX technology on the dozer sends machine operating information to a secure website utilizing wireless technology.

Doosan Launches It’s Largest, Most Powerful Wheel Loader compliant with regional market demands


oosan Infracore Construction Equipment has launched a new generation DL550 wheel loader, the topof-the-range model in the company’s new family of wheel loaders, that is intended for markets where emission regulations are less extreme.

With a bucket capacity of 5.4 m³, the DL550 wheel loader is designed to meet a wide range of material-handling needs from loading and transporting granular material (such as sand and gravel) to industrial, mining and quarrying applications. A key feature of the new wheel loader is the Tier 2 12.7 litre Scania DC13 turbo-charged, air-to-air intercooled diesel engine, which is ideal for use in such markets, delivering a maximum output of 294 kW at 2100 RPM. The high engine power output is combined with new ZF transmissions and several other features which, in addition to reducing fuel consumption, provide exceptional performance, high durability, ease of handling and serviceability, and significantly enhanced operator comfort. The new loader has three engine working modes: ECO, NORMAL and POWER, allowing the operator to match output to Page 22

different applications, with different engine speeds and gear steps, according to the working mode engaged. With the ‘Power-Up’ function, the operator can manually adjust to the next highest working mode by applying a full stroke of the accelerator pedal. With this function, the operator can travel in moderate NORMAL mode and switch to POWER mode when it is really needed, such as when taking material from a pile. This capability helps to reduce fuel consumption. The ECO Bar on the display unit provides information in real-time about fuel consumption in relation to machine performance, allowing the operator to select the driving mode for the best fuel efficiency. There is also a new Auto Idle feature which, when activated, reduces engine speed by about 200 RPM after 10 seconds if there is no machine movement. Auto Idle is ideal for applications with long waiting times, such as truck loading and lowers fuel consumption significantly.

New ZF transmission The new transmission, is developed to maximum modern engine technology by improving the transfer of power from the engine to the wheels. This contributes significantly to the overall reduction in fuel consumption. The new transmission also provides better response and acceleration, especially on slopes. Engine speed variation is less, due to smaller gear steps, and lower engine speed throughout the whole drive range assists in lowering fuel consumption. A 5 gear transmission with torque convertor lock up is available as an option. When activated, the optional torque-converter-cut-off (TCCO) system is switched on automatically. This provides a direct mechanical connection between the engine and transmission without loss of power and torque by the torque converter. Tests show that fuel consumption can be reduced by as much as 10%. With the intelligent clutch cut-off system engaged, the driver is able to disconnect the transmission from the engine by operating the brake pedal, to have 100% engine performance for the hydraulic system. As a result, movements are faster, breakout force is maximized and fuel consumption is reduced. New ZF Type II axles are more durable to deliver a longer lifetime. Rolling resistance for the axles is also reduced, improving traction and decreasing fuel consumption. The axles have a hydraulic differential lock as standard. This function is engaged via the operator pedal or in automatic mode, depending on the torque resistance in 1st and 2nd gear. The advantage of the hydraulic lock system is that it has less rolling resistance compared to the limited slip system and causes less axle stress. Like all new generation Doosan large wheel loaders, the DL550 is equipped with load-sensing, closed centre Contractors World - International Vol 3 No 9

controlled, variable hydraulic piston pumps to i m prove pe r form anc e and reduce f uel consumption. With load sensing, the hydraulic pumps receive a signal from the main control valve (MCV) informing how much oil is needed.

High Operator Comfort A new cab design features improvements both outside – such as better visibility due to a wider front glass section and an extended wiper blade area, better protection thanks to larger mud guards, improved hand rail and step designs and a new roof cover - as well as inside – such as the new instrument panel with integrated vehicle control unit (VCU). The control panel has been redesigned to allow the operator to choose the information they want on the display. Via the main menu, the operator has access to several functions and machine information. Pressure, temperature and engine speed can be monitored in real time. Detailed operating information is available via the Special Menu. More foot space has been created by relocating the reservoir for the wiper water to the outside of the cab.

Durability and Serviceability New kinematics and a larger cylinder on the lift arm have allowed the main pressure in the front hydraulic system to be increased by up to 70 bar, with a corresponding increase in breakout and lifting forces. An automatic front control system allows the operator to save one low and one high position. The boom raise ‘kick out’ function reduces cycle times and increases operator comfort. ‘Return to dig’ positions can also be saved. The radiator fan is hydraulically driven. Changing the fan direction for cleaning the radiator can be done manually from the cab, without having to switch off the engine. A larger opening angle for the side door improves serviceability. The 90° swing-out fan with swing-out side doors provides easy access to the rear for cleaning the new one block radiator.

• A-shaped pylon rising against stormy winds • Pilosio Scaffolding For Art • Mass house building • Accelerated construction with system components • Harsco’s Solution For Storm Water Tank Construction • New large formwork sheets reduce joints

O n the Kåfjord, near Alta in Norway, the construction group ALPINE is currently erecting the northernmost bridge pylon ever to be formed by Doka. The greatest challenge in the building of this 270 m long bridge is the harsh climatic conditions that prevail at this geographically exposed location

A-shaped pylon rising amidst the stormy winds of Norway In the far north of Norway – 80 km south of Hammerfest and around 1300 km north-east of Oslo – the Austrian construction group, ALPINE, is building a 270 m long and 8.5 m wide single-tower cable-stayed bridge across the Kåfjord. Doka is supplying a dependable, high-performing formwork solution for building the A-shaped pylon and its foundations, together with the foreland bridge. As well as a track-record of successful collaboration on previous projects, a key reason why the client awarded the contract to Doka was the company’s high capability and expertise in the field of technically demanding automatic-climbing projects. Doka also scored highly for its knowledge of the difficulties of working in this region, and for the fact that its Trondheim branch gives it a ‘relatively’ local presence. Two special challenges make the Kåfjordbrua a particularly interesting project. Firstly, the province of Finnmark, in which Alta lies, counts a mere 1.5 inhabitants per square kilometre, making it one of the most sparsely populated regions of Norway; it is also one of the remotest (1400 km from Trondheim by road). This has made it absolutely imperative for the site and the deliveries logistics to be seamlessly and flawlessly co-ordinated between the Doka branch in Trondheim and the site team in Alta, right from the beginning of the project. “The vast distances make transport very cost-intensive, so we can’t afford to waste a single metre of loading space”, says Doka project manager Andreas Heimberger. Secondly, the wind-speeds encountered out in the fjord, with working winds of 80 km/h and storm winds of up to 170 km/h, are so high that the safety requirements made of the equipment fielded here are very stringent indeed.

Custom-tailored formwork solution To help it rise to the challenging conditions applying to the building of the 72.5 m high pylon, ALPINE opted for the self-climbing formwork system SKE50 plus, which adjusts readily to difficult structure geometries. Nine ‘SKE50 plus’ automatic climbers, combined with 63 m² of specially tailored large-area formwork Top 50, Page 26

The ballast box is being cast in two steps, with the outside formwork staying in position for both casting-steps so as to ensure exact placing of the tensioning cables.

are being climbed in a weekly cycle to construct the pylon legs, both of which incline by ten degrees from the vertical. Following modifications to the dismounted platforms, eight ‘SKE50 plus’ automatic climbers remain in use on the head of the pylon. The automatic climbers of the end faces do not need to be modified, as they can continue climbing unhindered right through until the top of the pylon. The block height of the legs is 4 m up until the point where they merge, and 2.5 m thereafter. The bridge superstructure is being constructed using the cantilever method. Great precision is required with placing the tensioning cables in the ballast box at the short end of the bridge. To ensure sufficient adaptability to the shape, large-area formwork Top 50 was selected for this. The ballast box is being cast in two steps, with the outside formwork staying in position for both casting-steps so as to ensure exact placing of the tensioning cables.

Safety – the overriding priority “For us, Doka automatic climbing formwork is the most efficient solution there is for building this bridge pylon efficiently and quickly. In particular, being able to jump the formwork units so quickly using hydraulic cylinders, and close and open the formwork in such a straightforward way, really helps work to move ahead fast”, comments Alpine supervisor Stefan Ebenbauer “Because the climbing scaffolds are always firmly anchored in the concrete, the platforms can be ‘climbed’ safely even under high wind loads. The working platforms are generously sized and are fully railed-in, with ladderways permanently integrated in the climbing units, so we can always be sure of working in safe conditions”, adds Alpine foreman Herbert Etzold. A combination of large-area formwork Top 50 and Staxo 100 load-bearing towers is being used to form the superstructure of the 101 m long access viaduct. To make it unnecessary to deliver any extra formwork equipment for the six circular pillars of the viaduct, it was decided to re-use the Framax framed formwork that was already on-site following completion of the abutments. Profiled timber formers were added to this Framax equipment, enabling the pillars to be cast in the desired concrete quality.

Basilicas, art exhibitions and period buildings: An MP multidirectional system conquers the art world

Pilosio Scaffolding For Art: A Very Italian Story 1. Pilosio For: Basilica Di San Bernardino In L’aquila The Ministry of Cultural Assets and Activities used Pilosio’s MP multidirectional scaffolding for the restoration of the very beautiful Renaissance Basilica di San Bernardino in L’Aquila, seriously damaged during the 2009 earthquake. Pilosio’s technical office was able to solve the difficulties that the widespread and heavily damaged site presented. The requirement was to make the Basilica safe through the creation of a temporary structure that would allow the workers to proceed in complete safety with the delicate operation of restoring the cupola of the marvellous Renaissance Basilica and, at a later stage, the bell tower. The difficulties were that the scaffolding could not be supported by the roofs or the existing structures due to their precarious situation. In the design phase, Pilosio had to provide an overhanging scaffolding “bridge” to allow the unstable parts of the building to be surmounted. The first operation involved making the Basilica’s interior safe. Pilosio designed and supplied a safety portal inside the Basilica’s central nave, and the chapels of the side naves, in order to protect the workers from any material falling from the ceiling and roof. The portal was 17 metres high and around 50 metres long and ran the entire length of the nave up to the presbytery, with overhanging access to the base of the internal cupola. Complex scaffolding was provided to enable the external restoration of the cupola and tambour to proceed. The option chosen was an overhanging portal in which the scaffolding left the ground at Pizza del Teatro and, passing over Page 28

Contractors World - International Vol 3 No 9

the Basilica and completely encompassing the outer surfaces of the cupola, returned to the ground in the internal Cloister. From the outside, the Basilica seemed to be inside a cage of sturdy scaffolding. A large team of restorers worked in complete safety on Pilosio’s MP scaffolding and a site lift, manufactured by Electroelsa (a company belonging to the Pilosio group), allowed easy access to the service floors with the material required for the restoration works. In total, the volume of scaffolding was around 35,000 square metres in a layout of 50 x 28 metres to a height of 44 metres. The works then continued with the restoration of the interior part of the cupola, which was in a precarious condition. Pilosio designed and constructed a walkway at the height of the join of the cupola, with a loft that followed the cupola’s inner line, and the creation of a work area to support the hydraulic jacks that were used to push the collapsed parts of the cupola outwards and put them back in their original positions.

2 Pilosio For Keith Haring Exhibition In Udine There was a key role for Pilosio’s MP scaffolding in the prestigious “Keith Haring Extralarge” exhibition, featuring the “Ten Commandments” series and the painting “The Marriage of Heaven and Hell”, the largest painting on canvass ever created by Haring. The paintings of the famous American artist are displayed in the deconsecrated medieval church of San Francesco in Udine until February, 2013. The staging inside the church leaves the view of its interior clear by almost creating a second exterior, a sort of “church within a church”. The structures on which the works are firmly fixed and supported, were built with Pilosio’s MP multidirectional scaffolding, confirming the great flexibility and adaptability of this product in all contexts. The structure in MP scaffolding was designed to be self-supporting (an indispensable requirement given the presence of frescos on all the walls) and did not require ballast, which the fragile flooring of the church would not have withstood. Pilosio scaffolding was chosen by the exhibition designer since, originally, the artist had begun as a street artist.

Meva AluFix used for fast-track housing development in the Phillipines.

Mass house building A new method using MEVA’s wall formwork AluFix saves time and money Modern homes are an increasing demand by the growing middle class in South East Asia and the Middle East. Building residential high-rises and housing blocks fast and efficiently without compromising quality or safety is a major challenge to local contractors in many Asian countries. One solution to the challenge is fast tracking the partition walls inside the buildings that is growing is MEVA’s crane-independent wall formwork system, AluFix, which is extensively used for fast tracking because the panels can be carried manually and are ideally geared to the heights of partition walls. Fast-tracking partition walls eases the building process. How does fast-tracking work? First, the structural walls of a floor are erected, but no partition walls. Then, large panel areas of slab formwork are set up. This is done much faster than usual because there are no hindering inside walls. After pouring the slab and stripping the slab formwork, the partition walls on that floor are poured.

Sizes to fit any wall size With four panels heights from 132 to 300 cm and over 10 widths from 20 to 75 cm per height, AluFix easily handles typical room heights and partition walls of any size and form. If the walls differ in height and width from standard sizes or from each other, the panels can be combined vertically and horizontally to reduce the panel selection to be held on stock on site. Standard fillers are available to bridge gaps. As the formwork for the partition walls extends to or almost to the poured slab, the concrete is poured through holes in the slab. If this is not possible, e.g. under RC beams, panels with filling nozzles are used for concrete pouring.

The most efficient method with the best concrete surface Subsequent partition walls can also be erected using hollow bricks, Spraycrete or Macro panels (prefabricated concrete hollow panels). Yet by using AluFix, contractors save effort, time and costs for different reasons: no material (hollow bricks or Macro panels) needs to be transported, the concrete finish achieved with AluFix is much better than with hollow bricks and plastering work is minimised.

Accelerated and safe construction with system components

Until the inherent load-bearing capacity has been reached, in the area of the cantilevers the structural and formworking loads from two complete floors are transferred via the PERI VARIOKIT shear frame construction into the storeys below

The Rotterdam-based architect, Rem Koolhaas, has given his high-rise ensemble a huge “jolt” with a result that has placed high demands on the construction work. Therefore, the supporting structure concept for realizing the cantilevers at a height of 86 m is an essential part of the comprehensive PERI overall solution. De Rotterdam will be the largest building in the Netherlands – situated in the immediate vicinity to other architectural highlights such as the Erasmus Bridge by Van Berkel & Bos, the inclined high-rise building by Renzo Piano and the World Port Center by Sir Norman Foster. Once completed, the 150 m high multi-storey ensemble on Rotterdam´s Wilhelminapier peninsula on the south bank of the river Maas, will consist of three complex designed towers standing side by side and connected to each other. The West Tower has 45 residential levels; the 41-storey Central Tower is designed to be used as office facilities only; the 43 floors of the East Tower feature both office space as well as a hotel tract. In total, around 250 apartments, 280 hotel The PERI truss girder solution consisting of VARIOKIT system components ensure safe transfer of loads during construction of the cantilevered floors.

The three towers of the 150 m high De Rotterdam multi-storey ensemble are positioned very close to each other and are offset halfway up.

rooms and 60,000 m² of office space will be realised. The five-storey base section of the building has retail stores, restaurants, conference rooms and a fitness centre – as well as three parking decks on the ground floor and two basement levels. A native of Rotterdam, renowned architect Rem Koolhaas has given his high-rise complex a huge “jolt” – shifting the upper half of the building to the side with a horizontal offset to the west and north. In so doing, at a height of 86 m, the 24th and 26th floors respectively along with the remaining upper storeys cantilever outwards up to 9 m. The construction site crew of Ed. Züblin AG, Stuttgart, has vast experience in realising high-rise buildings and the structural work is scheduled to be finished in early 2013 whilst the de Rotterdam CV project group plans to have all construction work completed by the end of the year. The rapid construction progress is supported through the use of comprehensive and ideally combined PERI system solutions. In particular, the supporting formwork solution for the cantilevered sections is an important component of the PERI overall concept.

Supporting structure with system For realising the huge cantilevers at the great heights, PERI engineers developed a supporting formwork solution on the basis of the VARIOKIT engineering construction kit. For this, rentable system components are being used to a large extent, supplemented by a project-specific bracing construction. The flexible arrangement of the shear frames is carried out here whilst taking into account the respective geometry and loads of the structure. Also managed is the range of mounting parts through to the masts of the tower cranes positioned in the building itself. For dimensioning the beam heights in the West Tower, transferring the large loads from the 8.88 m cantilevers for two complete floors of the building and the low 3.52 m height of the storey below, had to be taken into consideration. For the Central and East Towers, a double-storey can be used for this purpose – here, the supporting formwork solution not only serves for transferring the loads from the cantilevers but also as a supporting structure between the floors. Extensive PERI know-how is used to good effect especially in the beam extensions when the inherent load-bearing capacity of the building has been reached. The fact is that due to reasons of space, the shear frames cannot be simply retracted The striking procedure is an important component of the PERI solution: with the help of the SKYTABLE moving technique, the truss girders can be pulled horizontally from the building. Page 32

Contractors World - International Vol 3 No 9

and disassembled within the storey itself without requiring direct crane support. For this purpose, the construction site crew is using the PERI lifting carriage that is normally used in connection with SKYTABLE large slab tables. The advantage of the PERI method – which was developed in and has been used for many years in North America – is that the shear frame is pulled horizontally from the building by means of a crane lift, a special chain block system and rear carriage.

Faster working through enhanced safety With the RCS P climbing protection panel from PERI, the two topmost floors under construction are completely enclosed each time. As a result, site personnel are prevented from falling and protected from strong winds at great heights – this means that forming operations are accelerated and work performance is greatly enhanced. Züblin requires only eight days for one complete standard floor. Already during the planning phase, the geometrical changes of the towers were taken into consideration so that those protection panel units affected by the offset could be moved to other sections without requiring any extensive modification work. The RCS solution demonstrated its high level of flexibility in the areas close to the slab edge where anchoring was not an option. In this situation, too, the slab shoes are securely fixed and ensure fast climbing procedures due to the continuing rail guidance.

Crane-independent forming operations With the SKYDECK panel slab formwork, floor slabs can be formed without the need of a crane. System components made of aluminium to facilitate the transport and, in particular, shuttering and striking can be carried out manually. The systematic and, therefore, easy tounderstand assembly sequence accelerates the construction processes and ensures that time requirements can be accurately estimated. In addition, the use of the drophead and the possibility of early striking also reduces the amount of panels and main beams required on site. For the floors in the base section, the systematic assembly sequence and the high degree of safety for each standard bay has already been achieved using the SKYDECK platforms and the cantilevered 375 SLT main beams, also at the slab edges. For The modular MULTIPROP system was used to provide the load-bearing the large supporting heights reaching over several elements for the base section – joined together vertically with connectors and horizontally by means of frames. floors, the construction crew have combined SKYDECK with the MULTIPROP load-bearing system. The lightweight aluminium individual props can be vertically connected to each other by means of the MULTIPROP connector – and joined together using MULTIPROP frames to form extremely stable shoring towers.

Pre-assembled units De Rotterdam is encircled on all sides – longitudinally between the road and the Maas river as well as between two neighbouring buildings at the ends. The narrow construction site therefore has very limited storage space. As a result, PERI supplied the RCS protection panel units and VARIOKIT shear frames already pre-assembled to the construction site. This means that these are lifted directly from the truck by crane and taken immediately to the designated place of use. This saves valuable crane time; in particular, no additional storage facilities and assembly area are required.

Harsco’s Proven New Solution For Storm Water Tank Construction Harsco Infrastructure has provided a bespoke access solution to John Murphy & Sons (JMS) for the Maryport UID scheme in Cumbria. United Utilities contracted JMS to construct the major storm water handling facility. The access solution involved the use of modified mast climbing work platforms. This bespoke idea was first used at the JMS site at Deephams for Thames Water, and has been adapted to suit the Maryport scheme. The construction of a large-scale detention tank at the existing pumping station is to prevent storm water surges entering the Solway Firth. The new 25 metre circular concrete tank has been built inside a secant piled wall and is 14.5 metres in depth. “The in-situ reinforced concrete walls of the tank would traditionally be built using scaffolding,” explains Harsco’s Mechanical Access Director, Cameron Reid. “However, this can historically prove expensive and difficult to manage inside the cramped excavation pit. Working with the civil engineering contractor, JMS, we developed the innovative use of mastclimbers to enable the concrete formwork to be poured inside the excavation whilst at the same time providing full access to the walls of the shaft.” Harsco provided six mastclimbers for the project, each fitted with a special curved face that allowed the workforce direct access to the tank walls as they were being built.

New large formwork sheets reduce joints Until recently, the large-area sheets available for use on formworks requiring small numbers of joints have tended to be smooth-surfaced ones. In cases where both vibrant wood-structured surfaces and harmonious sheet-patterns are required, joint-reduced formwork elements can now also be faced with the new extra-wide XXXL format sheets 3-SO from Doka A familiar and well-proven product on countless sites over the years, the bright yellow 3-SO formwork sheet is an ÖNORM B 3023-compliant 3-ply formwork sheet made of spruce that is designed to deliver an even concrete surface with a uniform, slightly woodstructured appearance. It has proven to be a dependable quality for many repeat uses and quality concrete results, at a favourable price/performance ratio. Alongside the existing dimensions in widths of 50 cm and 100 cm, the low-absorbency 3-SO formwork sheets are now also available in the XXXL-formats 250x125, 300x150 and 600x150 cm. These make it feasible to form fairfaced concrete surfaces with a small number of sheet-joints and thus fewer joint-related ‘shoulders’. The sheets have high dimensional and angle accuracy and are uniformly coated with urea melamine resin adhesive.

New Fully Weighed Continuous Mixing Plant Rapid International Ltd has announced the North American launch of the new Rapidmix400CW fully weighed mobile continuous mixing plant. This is the new generation of a proven continuous mixing plant range. The Rapidmix continuous mixing plant is now offering full weighing options for all materials aggregates, cement and water. Measurement by weight is a critical requirement of specifications and the Rapidmix400CW offers record keeping that is automated, precise and detailed. The new model now incorporates a 1200 mm belt conveyor between the aggregate hopper and the continuous mixing chamber. The weighing belt is supported on load cells and this measures the weight allowing the feed rate of the aggregate to be determined. The new plant also incorporates a cement weigh system, using a rotary valve feeding a weighed screw with twin outlets for discharging into the mixer. The water is monitored through using a flow meter. The first customer to take delivery of the new model was Rollcon LLC, located in Houston Texas - a leading contractor that specialises in providing quality roller compacted concrete (RCC) paving solutions for both public sector and private industry clients. Rollcon worked with Rapid USA Inc to first demonstrate the new machine, which has now been put into action on the latest phase of the Port of Houston development, producing up to 400 tonnes of material per hour. The contractor decided on the new plant after successful use of its predecessor, the Rapidmix 400C continuous mixing plant, on previous projects. It provides the mixing efficiency needed to evenly disperse the relatively small amount of water used in the mixing of RCC. Dump trucks then transport the RCC and discharge it into a paving plant, which places the material in layers typically up to 10 inches (250 mm) thick and 42 feet (13 m) wide. Port paving is really suited to Roller Compacted Concrete, due to its superb strength. It is capable of standing up to massive loads and specialised equipment. The machine can work on a variety of applications such as bentonite landfill sealing, dam construction, contaminated soil stabilisation as well as cement treated base for road construction. The system comprises a outloading conveyor fitted with gob Hopper/ 3 ply belt with heavy duty top cover and vulcanised joint; rapid twin shaft continuous mixer; 50 tonnes cement/ binder DESCRIPTION RMX400 silo; cement/binder weigh vessel with 4 Length of Machine (When ready for 18.5 m (60’-8’’) compression load cells; aggregate hopper with transporting) variable speed belt feeder; touch screen Width of Machine 3.00 m (9’-10’’) control panel and diesel powered 200 kva, 3 Height of Machine (When ready for 4.0 m (13’1-1’’) phase genset : . transporting) Height of Machine (When Erected) Weight of Machine total Weight on Rear Tri-axles Weight on Front Pin

New SUPERLIFT High Capacity Crawler Crane Terex Cranes has launched the Superlift 3800 lattice boom crawler crane, as the successor to the Terex CC 2800-1. When the CC 2800-1 was launched, it established a new benchmark in the crane industry, and became the reference in its class. The Superlift 3800 is not an upgraded version but, according to Terex, an entirely new crane in every aspect: from performance to safety features and from transportation to efficiency and speed of erection. The company says that the crane is designed and built for the way their customers work, to lift their heaviest loads as well as help their profits. “This is a very important launch for Terex. Improving on an existing model, we have created a completely new one through a customer driven innovation process which combines our experience with a focus on solving the needs of the customer. This illustrates perfectly what Terex Cranes is about,” says Kevin Bradley, President Terex Cranes. From the start of the project, customers were involved in the development of the Superlift 3800. The model comes with the award winning Terex Cranes Fall Protection System. Additionally, a protective railing has been installed around the superstructure and a new cab design improves overall visibility. Available side outriggers equipped with hydraulic cylinders and pressure sensors allow the operator to monitor ground pressure when mounting or dismounting long main boom lengths. For improved performance, capacities have been improved typically 20% overall in comparison to the predecessor. “When we started this project, we set ambitious goals”, explains Hans-Peter Franzen, Project Director. “And I am proud to say that we exceeded them.” System rigidity has been improved, for example the light extension LF can now lift loads up to 178 tonnes. The new crane can be delivered with an integrated wind kit in a Page 36

The cab on the new Terex Superlift 3800 has been given a complete redesign to improve visibility to the side and to the boom point. It is also exceptionally well equipped for comfort and productivity.

universal main boom system. With this the crane is capable of erecting wind turbines of 117 meters without using the available superlift boom configuration. For further savings, an assist crane is not required to help erect the main boom.

A great crane is a profitable crane. All aspects regarding erection and transportation are designed to provide the highest return on investment. Despite considerably higher rigidity, Terex managed to reduce the weight of the basic machine by 17 tonnes improving the crane’s transportability. Moreover, the measurements and the weight of components have been designed for ease of transport, including additional hoisting points on components. These and the hydraulic motors are positioned within the track frame reducing transport size and preventing them from being damaged during transportation. The Superlift 3800 is the first Terex crawler crane to feature the new cabin design. Providing operators with the best working environment, it is the result of extensive feedback from customer workshops, leading industrial stylists and experts in ergonomics. The result is “best crane cab in the market”, says Terex. Air conditioned, the cab features air-cushioned operator’s seat and an emergency seat. There are multiple storage areas and the entire cab can be tilted back for improved visibility of the boom point. A camera system monitors the rope drums. Cab display includes two full colour touch screen monitors with load moment indicator conveniently placed, as are other controls and switches for optimum operator convenience, The Superlift 3800 conforms to both, the European norm EN 13000 and the US standard ASME B30.5. It can lift a maximum load of 650 tonnes at a radius of 5 to 12 m and the maximum load moment accounts for 8,426 tonne. Main drive is via an 8 cylinder MTU diesel delivering 405 kW at 1800 rpm. There are three rope drums powered by hydraulic motors through closed planetary gear unit running in oil baths. All three drums have spring applied, hydraulically release multi-disk brakes and non-wearing hydraulic braking for load lowering

Latest in pipelayers - the Volvo PL4808D With a powerful Volvo D13H engine, claimed unrivalled lifting capacity and an extra wide undercarriage for greater stability, the heavy-duty Volvo PL4808D is designed for top performance in the industry. The latest addition to Volvo Construction Equipment’s family of pipelayers is the excavator-based PL4808D. Offering excellent stability with a 90 ton lifting capacity, it is designed to be highly productive while also being one of the safest and most stable machines in the industry. With its 360 degree swing capability, it can handle large, heavy pipes with ease and place them anywhere around the machine – an ability that is not possible with traditional side boom pipelayers. The patented design marks other significant technical advances over traditional side boom pipelayers — not just its superior stability but, if needed, also its ability to swap booms and convert into a standard excavator configuration. A digging kit is available and the hydraulics are optimized for both pipelayer and excavator operations. With up to 80% common parts with its sibling Volvo excavator, the servicing, wear parts replacement and maintenance requirements of having a PL4808D in the fleet is considerably eased.

Safe and secure Not only can the PL4808D lay pipes all around the machine, it can also operate on slopes of up to 30 degrees and rugged terrain. A heavy-duty mechanical slew lock firmly fixes the superstructure at any angle in relation to the undercarriage, protecting the transmission. This is useful when securing the load in a fixed position or during tie-in operations. The undercarriage has a high ground clearance, allowing operation in rugged conditions. A solid footing is secured, thanks to 30 in. (750 mm) tracks – which can be upgraded to wider 42 in. (1,050 mm) tracks for added stability and lower ground pressure. The extra wide undercarriage is hydraulically retractable, decreasing the pipelayer’s width to make road transportation easier. The PL4808D’s newly designed counterweight is situated to the side for a lower center of gravity and greater stability. A load management system (LMS) makes operation safer and easier. The LMS enables the operator to see what weight can be safely lifted at any position relative to the slope. Using inputs from the hook, boom and base machinemounted sensors enables the system to monitor boom angle, machine orientation and inclination. The computer uses this information to constantly calculate and display actual loads and related working loads, all in real time.

ContiTech’s Electronic Monitoring System Enhances Conveyor Belt Safety Longitudinal slitting in conveyor belts can be costly. Sharp objects are always ending up on the conveyor belt together with the materials conveyed. “If they fall in an unfortunate position during belt loading, they may get caught up and split the moving conveyor belt longitudinally. In the worst case scenario, the belt can be written off completely,” says Dr. Andreas Jungk, application engineer at the ContiTech Conveyor Belt Group. More protection against failures and expensive repairs is provided by the new electronic monitoring system Conti Protect Belt Rip Detection. It detects longitudinal slitting early on, minimizes damage, and thus cuts cost and reduces the accident risk. This makes it possible for the conveyor belts to be used longer to help in reducing operating costs and protecting the environment.

Automatic stop protects conveyor belt Monitoring takes place via conductor loops, which are vulcanized into the conveyor belt. These loops transmit a high-frequency signal between a transmitter and receiver. If a loop is damaged, the signal will break down on the receiver end. The system control then stops the conveyor belt automatically. How long the system needs to come to an emergency stop is determined by the distance between the conductor loops.
