sentinels of activity Despite being a long-time resident of the Gulf region, I still cannot stop being amazed by the astounding skylines of its cities, replete with forest-like outgrowths of architecturally splendorous towers and equally forest-like outgrowths of tower cranes. In fact, I would wager that, at the moment, the tower cranes in the region outnumber the actual towers they are there to build by a ratio of at least three-to-one. While, unlike the mid-2000s, these are not the times when rumours of most of the world’s tower cranes being concentrated in the region can be taken seriously, the sheer numbers of these sinuous, spindly spires still sticking up into the sky all around the region attest to their indispensability to the construction sector. These may no longer be the heady days of the pre-recession period when towers were rising up overnight and tower cranes seemingly even faster, but enough of the cranes still stand around as sentinels, either of ongoing activity at the towers still being built or of projects stalled and stymied by the recession. If that paints a rather bleak picture of the tower crane sector today, then fear not, for some of the biggest players in the sector – such as Raimondi, Comansa, Potain and its dealer NFT – tell us in this issue that the sector is still very much reaching skywards, albeit at a pace slower than before. With urgency returning to projects in the region, especially for Dubai’s Expo 2020 and Qatar’s World Cup 2022, the future is full of hope, they say, while revealing the region’s penchant for models with high jib-end lift capacities. Indeed, more and
more of these towering sentinels of the construction industry are no longer silent but markers of activity. Another sentinel of activity – this time a global one – is the triennial Conexpo-Con/ AGG exhibition in Las Vegas, USA. A bellweather for the industry worldwide, and especially for North America, it infused new life into the construction machinery sector last month with new equipment launches and a focus on new technology and future connectivity. The show signalled that the industry worldwide is ready to take on the challenges of the present with innovative solutions and is ready to go up again in the near-term. Speaking of going up, aerial work platform maker Genie has made sure that Dubai Parks & Resorts is doing just that in style with a trio of all-electric lifts that it delivered to the region’s biggest leisure destinations operator. The delivery marks the entry of Genie’s electric lifts into the region. Hopefully, it also paves the way for greater adoption of green machines and technology in the Middle East’s construction and machinery sector.

Daewoo Trucks celebrates a decade in UAE market
DAikinS WARnS On AGinG AiRCOnS Prolonged use of old air conditioners is detrimental to sustainability and energy conservation, as aging units draw more power,
Daewoo Trucks, South Korea, a part of India’s Tata Motors Group, held a customer get-together along with its UAE distributor United Diesel, Al Rostamani Group, at the Desert Palm Resort in Dubai last month. The purpose of the event – Daewoo Star Customer Meet – was to celebrate 10 years since the brand’s introduction in the UAE and showcase products such as tractors, refuse compactors, cargo trucks and other products from Daewoo Trucks’ stable, which were on display at the venue. United Diesel sold its first
lot of Daewoo Trucks back in 2007, and many of the customers from that lot were present at the event. Al Haddad, a UAE transport company, even drove down its first truck, bought from United Diesel in 2007. It has clocked 750,000km on its odometer without any major repair so far. Some of the other customers Daewoo felicitated at the event were Engineer’s Office, Utmost Transport and Al Rama Transport. The truck maker and its dealer honoured them for being their oldest patrons in this market. The gathering comprised
about 100 customers from across different applications and geographies who were loyal to the Daewoo brand and wanted to add more vehicles to their fleet. A product presentation by Sudhanshu Shekhar and Gurshaman Singh from Tata Daewoo Commercial Vehicles dwelled on the fact that the company offers almost 300 variants for the Middle East market and customers can choose from an array of engine, gearbox, axles and cabin options and configurations from 4x2 to 8x4 in cargo, tractor, mixer, dumper and special purpose vehicles.

German heavy moving specialist Goldhofer has introduced the STZ-VP (285), the latest addition to its STZVP family of semitrailers. The new model owes its name to the new 285mm tyres and is the lowloader semitrailer with the highest load-carrying capacity from the house of Goldhofer. Goldhofer said the model has its proven pendular axle technology and is available in configurations with between three and 10 axles and a choice of decks, namely vessel bridge,
crawler deck and flatbed. The axle load is a technically permissible 16t and a deck profile of just 200mm for the flatbed is claimed to be the slimmest on the market. Manoeuvrability is aided with a steering angle of up to 65 degrees. In order to keep maintenance costs to a minimum, axle suspension is available with a choice of tapered roller or compact bearings, to meet customers’ individual requirements in terms of mileage and maintenance intervals.

New MLC300 gives up VPC for versatility Manitowoc has launched a new version of its MLC300 crawler crane that shares many of the same features found in the original crane but uses a fixed-position counterweight in place of the original’s variable position counterweight (VPC) technology. Manitowoc said this new iteration of the crane is targeted at customers who want the 300t-size platform and compact footprint of the original model, but without the additional investment in features and moving parts that come with VPC. For this configuration, the MLC300 VPC trolley and tray have been replaced by a two-position,
stationary counterweight tray. The MLC300 with fixed-position counterweight serves all the lifting needs of a conventional 300t class crane and is ideal for owners who focus on limited duty-cycle applications with lighter loads and more repetitive lifts, Manitowoc said. The crane has a 96m boom and an optional additional 30m fixed jib. A 96m luffing jib can be added to extend reach to 150m. This latest iteration of the MLC300 is equipped with the company’s standardised operating system, the Crane Control System (CCS). The crane will be available from the second quarter of 2017.

Project Qatar 2017 to Provide access to one of the fastest growing construction market in the world
W
ith the construction industry in Qatar buoyed by a high budgetary allocation to infrastructure and the build-up to the FIFA World Cup 2022, as well as high growth forecasts by international bodies, an event such as Project Qatar, to be held from May 8-11 this year, assumes more importance now than ever before. According to a recent forecasts by The International Monetary Fund (IMF) Qatar is expected to reach an annual growth rate of 3.4%, the highest growth in the GCC region. Moreover, Qatar’s budget for 2017 has earmarked $26bn for major projects in key sectors; transportation and infrastructure alone have been allocated $12bn, representing 21.2% of the total budgeted expenditure. Qatar’s construction industry is further fueled by the FIFA World Cup 2022 and the Qatar National Vision 2030 (QNV 2030). The country’s transformation into a knowledge-based economy is well underway and is expected to gather pace as Qatar moves toward diversifying its economy, achieving sustainable development, and providing high standards of living for its population through its 2030 vision.
In this scenario, Project Qatar is the optimal business platform to access Qatar’s solid construction industry. Welcoming national governmental entities as well as regional and international decision-makers, Project Qatar 2017 is the unique gateway to construction opportunities in Qatar. Now in its 14th edition, the exhibition is a peerless platform for establishing regional and international construction networks. In 2016, the exhibition gathered more than 440 regional and international exhibitors, representing more than 1,050 companies from 38 countries, across 32,000sqm of exhibition space. The four-day business platform included 17 national pavilions and was supported by 18 international official bodies. “Based on our experience in Project Qatar we find this event to be very well organized, it allows us to meet with business professionals and it keeps our companies in touch with the evolution of the market”, says Mounif Kilani, economic and commercial counsellor at the Embassy of the Kingdom
of Belgium in Qatar. “We are provided with all sorts of useful information about the upcoming projects in Qatar, the market trends, what are the main activities that are now the focus in the construction field.” This year’s edition of Project Qatar will be held concurrently with Heavy Max 2017, The 14th International Exhibition for Heavy Machinery, and Qatar Stone Tech 2017, the 6th International Stone and Stone Technology Show. Other concurrent events will include Hospital Build, Qatar Sports Infrastructure and Qatar Transport and Logistics. Project Qatar 2017 will also include a free B2B Matchmaking service, specialised conferences and workshops, and construction site tours. Held at the Doha Exhibition & Convention Center (DECC), the state-of-the-art venue located at the heart of the Qatari capital, Project Qatar is an opportunity to generate valuable local and regional sales, and for visitors and companies to position themselves at the forefront of the Qatari construction industry.

Demag Duo in tanDem Rhine poRt lift
W
hen the monstrous drive system for an equally huge tunnel boring machine needed to be loaded onto a ship at the German riverine port of Kehl on the Rhine, MSG Krandienst GmbH decided to rely on the lifting power of a Demag duo consisting of two all-terrain cranes: a Demag AC 500-8 and a Demag AC 700-9. The 200t drive system needed to be lifted from the special heavy goods vehicle that brought it to the port and placed on the cargo barge that would carry it to its final destination downstream. Conditions were perfect on the day of the lift as the MSG team arrived at Kehl port early in the morning. They brought with them three trucks full of crane attachments and equipment and an escort vehicle, as well as the two Demag cranes. According to Reinhard Schmitt, crane operator of the AC 700-9, with clear blue skies and barely any wind, the weather conditions could not have been any better, and their day-long job was off to a good start. The team’s preparation work went smoothly. Four MSG team members needed only two hours per crane in order to get their machines ready for the lift, mainly made possible by the ease of setup of both Demag cranes. In order to lift the 200t load, the MSG team determined that the best crane configuration for the lift consisted of using a boom length of 25.5m and a counterweight of
100t on the Demag AC 700-9 allterrain crane. The star-shaped outrigger bases, extended to a length of 12m, provided the necessary stability. Demag says the bases are designed to attain a high level of stiffness while minimising the amount of deformation that occurs when lifting loads. For the AC 500-8 all-terrain crane, the team used a boom length of 24m and a counterweight of 140t, and extended the outrigger bases to a length of 9.60m. The AC 500-8 crane picked up the tunnel boring machine drive system with nine-part reeving at the hook. Once set up this way, the cranes were prepared and ready for the lift. What followed was the “fine art of lifting”, according to Schmitt. Working together, the AC 500-8 and the AC 700-9 lifted the drive system bit by bit to a height of 3m. “It all came down to how our two crane operators were able to work together with utmost accuracy. They had to stay perfectly coordinated in order to ensure that the weight would remain properly distributed between both cranes at all times,” explains Schmitt. A challenge, to be sure, but the crane operators’ experience and the high precision of the Demag cranes being used helped to easily overcome it, says Schmitt, who adds that it was possible to use a working radius of 14m to lift the drive system off the heavy goods vehicle, move it over the ship and then carefully put it down there.

“It all came down to how our two crane operators were able to work together with utmost accuracy. They had to stay perfectly coordinated in order to ensure that the weight would remain properly distributed between both cranes at all times�

Manitowoc cranes coMplete ten years of lifting to seal landMark chernobyl nuclear accident site
W
hen a giant arched shelter was slid into place over the Chernobyl nuclear disaster site in Ukraine towards the end of last year, it marked the end of seven years of toil to build the world’s largest land-based moving structure and cover one of the world’s biggest man-made disaster areas. It also marked more than a decade of crawler and tower cranes from Manitowoc working on the site. Resembling an aircraft hangar, the arch was first designed more than two decades ago, with construction starting in 2010. Its purpose is to cover the concrete and steel structure that was hastily built upon the ruins of the reactor of the erstwhile nuclear power plant, to contain the radiation that spread from it after an explosion tore it apart around 30 years ago. A massive engineering feat, the new arch measures 152m by 244m and is 107m high. Built to last at least a century, its purpose is to seal in all toxic material and radioactivity from the reactor. The structure is designed to withstand corrosion, storms and extreme temperatures, apart from a build-up of radioactivity inside it from the still leaking reactor. To accomplish such a marvel of engineering, in such extreme conditions at one of the world’s most difficult disaster sites, required equipment robust enough to be dependable under the stress that working in a radioactive site required. That equipment was a squadron of Manitowoc crawler cranes and Potain tower cranes. More than a decade ago, a few years before the actual construction started, ten heavy lifters from the Manitowoc Group rolled onto the site. Since then, the eight Potain tower cranes and two Manitowoc crawler cranes have worked non-stop, braving

high winds, rain and snow, the freezing Ukrainian winter and the toxic radioactive environment. With the arched shelter now complete over the disused nuclear power plant, many of the Manitowoc cranes employed on the project have been dismantled. Five of the eight Potain tower cranes have left the job, as have both Manitowoc 2250 crawler cranes. The cranes provided the majority of the heavy lifting work for the largest landbased moving structure ever built. Thibaut Le Besnerais, global product director for tower cranes at Manitowoc, says: “This really was a challenging job, and Manitowoc was one of only a few companies capable of providing equipment up to the task. Our involvement in this work dates back to 2005, when a special application Potain MD 3200 was used to build the first concrete containment shelter for the project. Our expertise and customer care was also crucial, as every task had to be meticulously planned within a highly detailed and organised working plan. We are extremely proud to be involved in this project and to play our part in such a feat of true engineering excellence.” The Potain cranes used on the project were four MR 605 B models, three MD 485 B units and one MD 345 B unit. The cranes were all supplied by Novarka, a consortium formed by French construction companies Bouygues TP and Vinci Grand Projects, which handled the project. Manitowoc’s local Ukrainian distributor, Hoisting Machines, provided technical support on-site. According to Manitowoc, the project, though challenging, was not new in terms of magnitude for Potain. The French brand’s cranes are employed around the world on large-scale industrial and infrastructure projects, and have featured on some of the world’s largest dam, bridge, power station and skyscraper developments of modern times. The purpose of the arch is not only to put a lid on the stricken reactor to prevent the further spread of radiation, but also to manage the disaster further by enabling workers to use remote-controlled equipment to remove residual nuclear fuel and other highly radioactive components for safe burial elsewhere. At the ceremony for the $1.5bn new arch project, Ukraine’s president Petro O. Poroshenko concluded: “Let the whole world see today what Ukraine and the world can do when they unite, how we are able to protect the world from nuclear contamination and nuclear threats.”

The star event for Volvo CE at Conexpo this year was the unveiling of its largest ever wheel loader, the L350H. The Swedish giant also debuted other new models, launched new services and showcased 28 machines at its stand. The new flagship 50t-class wheel loader was the biggest news of the show for Volvo. The all-new L350H is fitted with nextgeneration hydraulics and powered by a Volvo Tier 4 Final D16 engine, for high torque at low rpm. Volvo says the L350H now comes with a larger 7.3m3 bucket for maximum performance. Also claiming the limelight in Las Vegas was the L350H’s little brother, the L260H. Designed for heavyduty applications, the 34t machine is purpose-built to load on-highway trucks in just two even passes. Alongside the loaders, road machinery was in focus at the show, with new innovative compactors added to the Volvo line-up. Fitted with the flexibility of Volvo’s oscillation technology, which eliminates vertical vibrations, the double drum DD105 OSC offers high compaction performance while producing an undamaging oscillation movement. Volvo explains that this transfers less stress to the surrounding surface, enabling compaction in more delicate application areas, such as bridges, over pipes and close to residential areas. The DD120C and DD140C were also centre stage as the largest additions to the Volvo line-up of asphalt compactors, offering 20% improved fuel efficiency, new intelligent features and high centrifugal force. Visitors were also able to interact with Volvo’s new intelligent operator systems and machine monitoring technologies, such as ActiveCare Direct and Dig Assist. Other highlights on the Volvo stand included the A60H, the world’s largest articulated hauler with sixwheel drive; the EC750E, the latest and largest excavator available from Volvo in North America; and the HX02 battery-electric, fully autonomous load carrier concept.

A trAnsformAtionAl Green leAp The global construction sector is capable of making a “transformational leap” in sustainability and higher green standards, said top construction and environmental experts at the Construction Climate Challenge at Conexpo. The latest gathering of the Construction Climate Challenge tackled issues such as calculating the whole-life impact of building materials, the potential for cutting emissions in construction equipment and the environmental opportunities of delivering greener transport and mobility options, such as California’s high-speed rail system. Leading speakers also discussed the challenges of reducing carbon in construction. The Construction Climate Challenge is an initiative hosted by Volvo CE to promote environmental awareness, enhance collaboration and share best practices throughout the construction industry. The seminar was moderated by Dr Bryan Staley, president and CEO of the Environmental Research and Education Foundation, who discussed the consequences and complexities of calculating the lifetime environmental impact of building material choices. He said manufacturing processes, construction quality, transportation and material longevity all affect the whole-life environmental impact calculation, adding to the difficulty of accurately determining optimal building material choices. Margaret Cederoth, sustainability manager at the California High-Speed Rail Authority, said the railway project in the state was “setting a new green standard for infrastructure development”. The high-speed rail system will connect San Francisco to the Los Angeles basin in under three hours by 2029, at speeds of over 300kph. Describing how the adoption of new technology is leading to a new breed of intelligent, electric and connected machines, Dave Ross, VP, advanced engineering at Volvo CE, said: “Volvo

When Doha Festival City, the GCC’s latest meGa mall, WanteD emerGenCy stanD-by poWer, it turneD to the spanish Generator Giant himoinsa to install an 8.7mva baCk-up system that Comes on in just seven seConDs
i
magine you’re spending your Friday in one of the mega malls that dot the main cities of the GCC region – and the power goes out. In an instant all the brightness, the multi-coloured lights, the eye-catching displays, the glitz and glamour is replaced by the near-darkness that a completely enclosed structure such as a mall in the region will be in when unlit. Unimaginable. But plausible. For at least one mega mall in the region, however, that unimaginable scenario, if it ever happened, would last all of only seven seconds. Thanks to generator giant Himoinsa and its distributor FAMCO, Qatar’s spanking new Doha Festival City (DFC) mall has ensured the continuity of its power supply by installing generator sets that start up in record time in the event of a failure in the electricity grid. The 670,000sqm leisure destination will be home to more than 500 stores and restaurants, and a world-class entertainment complex, with both indoor and outdoor attractions unique to Qatar. With footfall expected to exceed 1.6 million people per month, safety and the proper operation of all business units at the mall will rely heavily on a system capable of supplying power in the event of an emergency. Not only that, such a system must meet the stringent requirements that the Qatar Civil Defence has envisaged for public spaces. Enter Himoinsa. And its HTW-1745 T5 generator sets. To feed such a huge complex and to respond quickly in the event of a power cut, the Murcia-based company came up with the solution of using five of the sets, each of which produce 1.736kVA of stand-by energy, making for a total of 8.7MVA of stand-by power. The units feature Mitsubishi engines and Stamford alternators that have been oversized and fitted with sophisticated control systems that synchronise the gensets. The gensets respond seven seconds after any power failure and are also prepared to work in a maximum ambient temperature of 55 degrees Celsius. But more about that later. To begin at the beginning, a lot of preparatory work and careful planning went into the project, both from the project owners and contractors as well as from Himoinsa. Speaking to CMME about the entire process, Massimo Broto, sales engineering manager at Himoinsa, says:
25 Himoinsa’s HTW1745 T5 generator set sits at its installed site in the bowels of Doha Festival City, from where it is ready to supply back-up power to the mega mall in seconds.

POWER PROJECT APRIL 2017
“We needed to prove that all the gensets would be able to run from a dead start, synchronise and produce power within 10 seconds… we achieved 7.8 seconds and we also proved the same results on site” “We actually got in touch with the contractor through our Middle East branch in Dubai, and our regional distributor FAMCO, more than a year before we delivered the units. We found out all the details of the project, especially its power requirements, and held detailed discussions about those requirements with the project engineers, giving them our advice and recommendations.” In typical Himoinsa tradition of being fully involved with their projects, those recommendations were in great detail, such as a consultant would give. Brotto adds: “We advised them about how to prepare the building for generator installation, how to manage the access and how to adapt the electric connections for the genset incorporation. “The most discussed topic was about the building management system because there were some very tough specifications to follow on the project, which included many procedures on the management of the circuit breakers for the generator as well as the mains, which we do not commonly see. For us it was a challenge because there were a lot of safety
procedures, simulations and synchronising. They asked for something which is more complex than the common practice.” Thanks to a detailed programming study of the control units, and after having subjected the units to multiple highly demanding tests, Himoinsa was able to guarantee a synchronised start-up time that, in fact, exceeded the project’s technical specifications. The objective was to guarantee an uninterrupted supply of electricity with generator sets capable of starting up in synchronicity with 100% of the load and in less than 10 seconds in the event of a failure in the supply of electric power. Speaking about the challenging requirements, Terry McGuire, regional general manager, FAMCO, says: “The biggest challenge of this project was to meet the stringent requirements of Qatar Civil Defence. We needed to prove that all the gensets would be able to run from a dead start, synchronise and produce power within 10 seconds. We managed to show this by the factory witness test, where we achieved 7.8 seconds, and we also proved the same results on site.”
Himoinsa’s technical team worked with the Doha Festival City project engineers right from the very beginning to integrate the power back-up into their design.
Himoinsa’s technical team subjected the five generator sets to a stringent test protocol, pushing the units to the limit of their operational capacity, to predict and guarantee a suitable response. Brotto adds: “We measured both the synchronisation times and the quality of the voltage and the current. We ran single-step load impact tests at 100%, guaranteeing a stable and rapid recuperation. We also simulated all the possible combinations of breakdowns to ensure that the system would respond in the event of a failure. And we did not endorse the tests until we had established that the units were reliable in all these situations.” Of course having a tried, tested and proven product in the HTW-1745 T5 generator helped matters, “but we pushed it as a model to an extreme performance level”, Brotto adds. “The PI734E alternator was oversized to 1900kVA and fitted with a programmable Digital Voltage Governor capable of providing an extremely quick response. Also, at the mechanical level, we guaranteed the temperature controls in the bearings and the winding so that they can operate safely and continuously, even for longer periods of
27 time, were that to prove necessary.” The gensets were fitted with Woodward speed controls to guarantee quick and reliable response. The Japanese technology Mitsubishi S16R PTA engines had all their vital parameters such as the oil pressure, the temperature of the water, the oil and the exhaust fumes measured continuously, making them communicate with a monitoring system controlling the condition of the engine. To ensure a fast response in the event of a grid failure, a water pre-heating system was added, as was a battery charger that ensures maximum efficiency. Himoinsa used Deep Sea control units that allow for syncing directly with a Dead Bus, thereby saving time manoeuvring the motorised circuit breakers in each set. The control systems are also connected to a PLC that handles the running of the generator sets and their interactions with the mall’s distribution system. With Himoinsa’s long track record of delivering units to the region, the company is adept at dealing with the harsh demands of the region’s climate – and the DFC generators were no exceptions. Brotto explains: “We are well acquainted with the demands that the GCC’s conditions place on any machine, so we have some standardised practices in place for the region’s heat and humidity. The first is to size the cooling package properly, which we always do when we supply a machine to this region. Another aspect that has been taken care of in this project is to oversize the engine and the alternator... in other words we
have adapted the complete set specifically for the unique demands of this project.” But now that the project has gone live, the generators will only be as good as the service and support they receive. And this is where Himoinsa’s dealer FAMCO comes in. “An important part of our business is our local presence, which is taken care of by FAMCO. They will provide after sales service, routine maintenance and spare parts. Only in special cases when the issue is out of their control, will we provide support, first from our branch in Dubai and then from our headquarters in Murcia, if required,” explains Brotto, who adds that to maintain Himoinsa’s high quality levels, there are constant training programmes for both in-house personnel as well as those from partners all over the world. “Our direct people, such as branch personnel, as well as technicians from dealers and partners, are all trained by our specialists and are ready to deliver our world class support locally to proper Himoinsa standards. For the DFC machines, that support will come from FAMCO. We are in this project together.” Echoing his sentiments about the effort being a joint one, McGuire says: “To execute a complex project like this, we needed the full support of the Himoinsa engineering team, as the requirements were enormous and highly technical.” That they have been successful is for all visitors to DFC to see. In the event of a power emergency, it’s a success that will be visible in seven seconds.
CaSablanCa PROJECT
a beautiFul FrienDship Himoinsa is no stranger to large-scale back-up power projects in the wider Middle East and North Africa region. In fact, the company recently added another feather to its cap in Morocco, where two Himoinsa HDW-750 T5 generator sets are guaranteeing the supply of electricity to the 26-storey Casablanca Finance Centre (CFC), the first building in the city’s new financial district. The tower will house the offices and headquarters of banks and financial institutions for whom any manner of power cut could entail losses of millions. Himoinsa says that to prevent this from happening in the event of a network failure, both generator sets will start working in parallel and will be able to supply up to 1.3MW of stand-by power. Himoinsa’s engineering team has redesigned the generators’ standard canopy in order to adapt it to the rather small room in which they are housed. As the height of the room precluded a high-level air outlet, the exhaust system was changed ad hoc to expel the gases and the hot air from the radiator from the front. Redouane Mouzani, the project’s head of engineering, the Spanish manufacturer was “the only company able to come up with a technical engineering solution adapted to the limitations of the room in the installation”. “We chose Himoinsa because of their flexibility in designing and manufacturing of the gensets, and because their engineering team works so quickly.” Mouzani added. Karim Housni Alaoui, project head for CEGELEC, the company in charge of the CFC tower project, adds: “We chose Himoinsa because they guaranteed an excellent after-sales service, a high availability of replacement parts, a quality product and because of how they quickly resolved the engineering challenges that the project presented.”

Bomag launChes tyreD roller Why get it? supports a range of operating weights with high fuel savings
Cat’s versatile D6t Dozer Why get it? versatile functions, advanced tech aids, robust transmission Caterpillar’s D6T bulldozer is one of the more recent additions to its dozer range. Apart from its highpower engine with several useful features in its transmission, the dozer is extremely versatile with its ability to be equipped with various Connect GRADE technologies from Caterpillar’s stable. A 215hp engine drives the D6T dozer, mated to a fully automatic four-speed powershift transmission with an integral lockup clutch. The transmission features an auto shift system which allows the operator to set the desired ground speed. The system then chooses the optimal gear and engine speeds to match operating conditions. The transmission has an additional gear between first and second that allows the dozer to remain in the most efficient mode for a higher percentage of time, which results in an increase in productivity of up to 2.5%, according to Caterpillar. The operating weight of the machine ranges from 21t to 25t. One of the biggest advantages of the Cat D6T dozer is that it can be equipped with various Connect GRADE technologies from Caterpillar’s line-up.
It comes equipped as standard with the Cat GRADE with Slope Assist, which automatically maintains preestablished blade positions without added hardware or a GPS signal. Another standard feature, the Cat Slope Indicate, displays machine crossslope and fore/aft orientation on the primary monitor, assisting operators to work accurately on slopes. The third standard GRADE feature, the Cat Stable Blade, complements the operator’s blade-control input to achieve finish grades faster with less effort. Among the options is the Cat GRADE with 3D, a factory-integrated grade-control system that provides 3D guidance for both production dozing and fine grading. The system features roof-mounted antennas and the Cat AccuGrade Ready Option is included, as is the AutoCarry system, which adjusts the blade for optimum load retention. Cat AccuGrade is available as a dealerinstalled after-market grade-control system. The AccuGrade Ready Option allows the machine owner to upgrade to an AccuGrade 2D or 3D system as needed.

Introduced at ConExpo 2017, Bomag’s BW 28 RH pneumatic tyred roller offers an enlarged ballast compartment for a high range of operating weight, as well as a higher maximum wheel load compared to previous models, allowing deeper static compaction. The operating weight of the BW 28 RH now extends from 8.6t to 28t, and maximum wheel load is 3.5t. The company says this offers an increased application range, from city streets and county roads to interstates and airports. Bomag says ballast can be added with concrete, steel and/ or underfloor weights, as well as water and dry or wet sand. Contractors can install four 750kg concrete weights, four 1.5t steel weights or two 700kg underfloor weights, and the 3m3 ballast compartment can hold up to 3t of water, 4.5t of dry sand or 6t of wet sand. The machine’s eight offsetting tyres overlap by 3.3cm and spread across 204cm. The front axle has three-way pivoting to evenly distribute weight across all the tyres, which, with an optional tyre inflation system, can vary in pressure from 29 to 116 psi. The BW 28 RH also features a 134hp Deutz Tier 4 Final diesel engine. With its ECOMODE load-dependent operation, the roller provides fuel savings of up to 30% compared to previous models, Bomag says.

Komatsu’s new exCavator Boosts proDuCtivity Why get it? enhanced power mode gives plenty of power in a light-weight package Japanese giant Komatsu has introduced a new excavator that boasts a 6% increase in productivity compared to preceding models. The PC170LC-11, introduced at CONEXPO in Las Vegas last month, uses an enhanced power mode to achieve this boost in productivity, claims the manufacturer. The excavator is powered by a 121hp engine compliant with Tier 4 Final emission norms. Komatsu claims that even though it produces plenty of power, its light weight keeps the total weight of the equipment low and makes it easy to transport the excavator. In fact, Komatsu’s product manager Andrew Earing says the excavator can be easily transported on an 18t trailer. Another notable improvement in the
new model is in its noise levels, which have been reduced overall, both for its operator as well as for others on the jobsite. Komatsu says it has reduced noise levels by more than two decibels inside the excavator’s cab, while an overall reduction of noise levels has also been brought about by the machine’s viscous fan clutch. The biggest benefit of the viscous fan clutch, however, is not in noise reduction but in power improvement. The component enables the excavator’s engine to yield a 5% increase in its flywheel horsepower (FWHP) rating. The excavator also comes with Komatsu’s Komtrax Level 5 technology, which provides machine data such as fuel and diesel exhaust fluid (DEF) levels, diesel particulate filter, regeneration status, location, cautions and maintenance alert information. Komtrax’s operator ID shows data by job, application
or operator. The data is presented on an updated seven-inch LCD monitor with a split-display mode, showing rearview camera and gauge data simultaneously. Other features on the PC170LC-11 include an auto-idle shutdown system, a platform-mounted DEF tank with sight glass, an ISO/backhoe pattern-change valve to easily switch joystick patterns, six work modes that match engine speed and pump flow to the job, and reduced hydraulic pressure loss in the main valve.

Case introDuCes its largest exCavator Why get it? huge power and capacity with fast cycle times Case Construction Equipment has introduced its most powerful excavator in its D-Series line-up, expanding its range with the CX750D, which is also the company’s largest excavator model in the range. The machine is powered by a 512bhp, Tier 4-Final engine and requires no diesel particulate filter (DPF). It also sports a larger cab and has new designs for the boom, arm and undercarriage, as well as several other improvements seen across the D-Series. Replacing the CX700B and the CX800B, the new model is available in two configurations, Standard and Mass Excavation. In the Standard configuration it weighs 71.8t and is capable of producing 34t of digging force with the Power Boost feature enabled. In the Mass Excavation model, the CX750D ME, it has a shorter boom and arm for greater breakout force, weighing 72.3t with the same digging force capabilities as the standard configuration.
Case says the boom, arm and undercarriage on the 750 have been updated with a “more robust” design to accommodate the machine’s greater power and productivity. The design also incorporates new arm and bucket cylinders that are larger and add another boost to performance. The 750, like Case’s smaller D-Series machines, offers faster cycle times, improved control and responsiveness, and greater fuel efficiency than previous excavator generations, claims the manufacturer. On the hydraulic side, the line-up features an electronically controlled hydraulic pump coupled with larger control and solenoid valves for improved breakout forces and more lifting strength. Inside the new cab, operators will find a fully adjustable workstation with a highback seat. Rear- and side-view cameras come standard and are displayed on a seven-inch widescreen monitor. This also displays real-time performance data including fuel consumption, operating hours and other machine information. Operators can select from three operating modes – Automatic, Heavy and Speed Priority – to tailor machine performance to the job at hand. SPECIFICATIONS

Doosan’s first hyDrostatiC loaDer Why get it? selectable torque transfer and a quiet cabin for efficiency Doosan’s new DL200-5 wheel loader is the first hydrostatic model in its line-up. The new 159hp model was designed to fill what the company saw as a market niche for a nimble, 1.9m3 machine offering the choice of either Z-bar or parallel-lift (DL200TC-5) linkage and efficiently handling powered attachments with its ability to modulate ground speed independent of engine speed. Equipping the DL200-5 with a hydrostatic transmission in lieu of a conventional drivetrain was a significant departure in design for Doosan. The hydrostatic system uses a three-mode traction management system that allows the operator to match traction to the job-site in order to prevent wheel spin. Operators can select Max for 100% torque transfer to the wheels, Slip to reduce torque by 50% when working in softer ground conditions or Traction Control, which provides three more choices, ranging from 70% to 90% torque transfer. The DL200-5 has a closed-centre, variabledisplacement-pump hydraulic system that can produce flows to 49gpm and working pressures to 3,190psi. Hydraulic controls are pilot-operated, and a third (auxiliary) spool and control lever are standard, but piping down the lift arm is optional, as is a fourth auxiliary. Standard hydraulic system features include boom float, adjustable boom kick-out and adjustable automatic return-to-dig. The cabin’s low 72dB(A) noise rating, , results from a variable-speed cooling fan, double-wall muffler, soundproofing materials throughout the engine compartment and a tightly sealed pressurised cab.

Find a Firm Footing It is important that the footings and foundations for a tower crane installation be designed according to the relevant technical standards and recommendations, taking into account the geo-technical specifics of the location. The installed footings and foundation should be certified by a competent person, such as an engineer, before tower crane installation begins.
Provide rated caPacity limiters When an overload is detected, a rated capacity limiter prevents further overloading of the crane by stopping all functions that will increase the overload. Rated capacity limiters should be provided on tower cranes regardless of their age. The limiter should prevent hoisting a load exceeding 100% capacity or 100% of the specified radius.

working radius indicator A radius indicator displays the radius of the suspended load generally measured from the centre of the slew ring. The working radius should be displayed in metres and be accurate to +10% and -3% of the actual radius. A radius indicator should be fitted on all tower cranes as their maximum lifting capacities change with every increase or decrease of the radius.
Pit-stoPs on the climb Tower crane operators climb hundreds of feet to get to their workstations, and ladders need to be designed appropriately for their safety. Landings between ladder sections, with changes in direction of the ladder, should be provided where possible, to minimise fatigue by allowing rest breaks and reduce risk of injury in the event of a fall. The vertical distance between landings should not exceed six metres.

A
t the peak of the construction boom in the GCC region in around 2007, it was rumoured that the region was host to more than 30% of the entire global supply of tower cranes. While the veracity of those numbers could never be established, what is definite is that those numbers, whether true or trumped up, have since fallen off drastically. Tower cranes still remain ubiquitous in the region, however, as the most visible construction equipment, standing sentinel to either activity or stasis in the region’s highrise projects. One of the biggest players in the region’s tower crane market today is Manitowoc’s Potain, supported by its Middle East dealer NFT Specialised in Tower Cranes. Nawar Al Zahlawi, business development manager at the Abu Dhabi-based company feels that even though the market is not at its previous high levels in the current global slowdown, things have started picking up. “The GCC is actually one of the bright spots in the global tower crane sector,” says the executive from NFT, which also has operations outside of the Middle East in markets such as the UK. “We are doing reasonably well in the European markets and have cranes spread out over the continent in France and Denmark. But closer home, the market is more fragmented.” Dubai and Doha are driving the regional market, he says, while Abu Dhabi seems to have suddenly lost appetite for big construction projects and consequently for tower cranes. “We had almost 50 cranes in the Al Ruwais area of the UAE capital when we got the deal in 2014 for a project to build industrial accommodation. Those cranes were dismantled in 2015. Other than that, you can count the projects and cranes on your hands. We have some projects on Sadiyat Island, but we were supposed to have large projects such as the Guggenheim Abu Dhabi and the Sheikh Zayed National Museum, which have been pushed back. Now work is on

comansa’s first luffinG-jib crane
Comansa CM launched its first luffing-jib tower crane, the CML190 at Bauma China in December last year. The crane is the first in its CML Series of luffing-jib cranes, which will be completed in the following months with more cranes. The CML190 crane comes in two versions of maximum load capacity – 12t and 18t - both with maximum reach of 60m and different jib configurations every five metres. Both versions offer maximum jib-end loads of 1.5t and rise up to a maximum free-standing height of 64.4m. This luffer, as well as the upcoming models of the CML
only on the Louvre,” Al Zahlawi says. “We put cranes on the Louvre and we were expecting a lot of other projects in Abu Dhabi, but it seems all their funds have been allocated elsewhere.” However, next-door Dubai is a bright spot, and Al Zahlawi says: “Dubai has enough work to keep everyone in the Emirates busy. The city’s growth is making up for the losses elsewhere such as in Abu Dhabi and Saudi Arabia. We are really looking forward to the new developments and we’ve already started working there, having supplied a couple of cranes for projects related to the Expo 2020, where the Al Futtaim Group recently won a major construction contract and they have three years to build the project.” Although work related to the Expo is starting later than the industry expected it to, there is hope that the renewed activity will bring in more investment, which will keep the construction sector busy and, in turn, require the supply of tower cranes, he adds. Historically, NFT has had a stranglehold on the Abu Dhabi market, and al Zahlawi claims around 70% of the tower cranes in the UAE capital are Potains that it has supplied. Dubai, however, is a different story. “Dubai is more competitive. As one of the earliest to enter the market, we are still competing well, but our market share now is lower than it used to be 10 years ago. There is more work and so there are more players vying for a slice of the pie. At the moment that pie is large enough to support many players.”
Series, have been designed under Linden Comansa’s modular system. Therefore, every component of the crane is light and compact to allow easy transportation and fast erection. Furthermore, the hoisting and luffing cables come preinstalled from the factory for a faster installation of the crane. Among the main technical features of the new cranes are the forward placing of the hoist mechanism, in the front of the slewing part, which allows more drum capacity and a reduced counter-jib radius. There are also different hoist winch options to achieve maximum hoist speeds of up to 178m per minute and drum capacity for up to 1,280m of wire rope. All hoisting, slewing and luffing movements are frequency controlled for smooth and precise manoeuvres. The new CML cranes feature a control system, popularly known as “Level Luffing”, which allows electronic coordination between the luffing and hoisting mechanisms. A hydraulic push and retention system allows a smooth luffing movement of the jib. The speed of the luffing movement changes depending on the jib angle to ensure a fine approach of the load. Both hoist and luffing movements allow ‘microspeed’ mode for optimal positioning control while the luffing drive includes a double brake system to boost safety. Both versions of the new model will be available for customers in Asia, Middle East and Oceania, from 2017.
Raimondi aims high One of those players vying for a slice of the pie is Raimondi. The Italian brand is now owned by Dubai-based KBW Investments, which has given it synergies within the KBW group to fall back on. “We’ve been making strong progress in the Middle East in recent months, and we’re working on some highly prestigious projects in the region,” says Domenico Ciano, technical director at Raimondi Cranes. “Our parent company, KBW Investments, continues to support us through cross-portfolio engagement. For example, Klampfer Middle East, a KBW Investments company that was founded jointly with Sharjah’s Basma Group and Klampfer GmBH of Austria, contracted us to erect a Raimondi MRT152 crane at an onsite project for a period of 24 months. We look forward to building on our recent success.” In order to do that, however, Raimondi first needs to deal with what Ciano thinks are some of the traditional aspects of the GCC market – lack of awareness, price-sensitivity
and difficulty of access. “In the GCC, historically, you could say that the heavy machinery segment was very hard to access for outside players. It was nearly unheard-of to come into this market and make headway without some sort of local footing,” he says. “For Raimondi, specifically, as a European manufacturer, you could say that a challenge is the lack of education about our quality versus that of Chinese manufacturers, for example. For the extremely price-conscious, more education on quality, durability, and real investment value is needed. If you think you’re saving money by opting for a ‘budget’ model with a vague manufacturing history, get in touch with Raimondi and we’re happy to tell you why our heavy lifting machinery is the better route.” Going by Raimondi’s performance figures and forecasts, many customers also seem to agree with that ‘better route’. KBW’s understanding of and focus on the Middle East has started paying off for the Italian brand, with significant sales last year. As KBW chairman

“If you think you’re saving money by opting for a ‘budget’ model with a vague manufacturing history, get in touch with Raimondi and we’re happy to tell you why our heavy lifting machinery is the better route”
Ahmed Alkhoshaibi revealed to CMME in an exclusive interview last November: “During Q1 and Q2 (2016), 35 cranes were sold in the Middle East. Rounding of the year, we’re forecasting 60 cranes – with the bulk of these heading to Qatar and Saudi Arabia. Currently in Algeria, there are eight Raimondi MRT294s installed as part of a large scale project.” For Linden Comansa, agility in the market is the deciding factor behind success. The company trusts its strength in speedy supply of parts and service to compete in a market where it eyes the Chinese presence ominously. Mariano Echávarri, communications and marketing manager for the company, feels that the tower crane market has been getting tougher in genera for the brand in the last few years. While the entry of Chinese brands with their lower prices is a major factor, another cause is the lower rental prices, which makes more difficult to amortise its higher-end equipment in less time. Echávarri feels that Linden Comansa’s edge is the amount of care and attention it gives to providing service and back-up to its customers in the region, which few other manufacturers care about. Preference for heavy lifters What all manufacturers do pay a lot of attention to, in fact, is the type of cranes that customers are asking for. Raimondi’s Ciano says one of the trends of the GCC market is a preference for cranes with heavier lift capacities, such as Raimondi’s MRT294.

While the company’s range includes cranes with a variety of capacities and of all types flattops, hammerheads and luffing jibs – with various height and jib length configurations, customers in the Middle East have shown a marked preference for the MRT294. The popularity of the crane, with a jib length of 76m and maximum lift capacity of 16t up to 30m, is in line with the region’s demand for high jib-end capacity and jib reach for larger job sites. According to Ciano, while Raimondi released the MRT159 topless and LR213 luffing-jib cranes last year, the MRT294 still remains it best seller in the region. For Linden Comansa, luffing-jibs seem to be where the demand is. The models by definition are ideally suited to tighter spaces and are especially popular for high-rise construction in congested built-up areas within cities. According to Echávarri the company has seen great interest in its 18t LCL280 luffingjib model from tower projects of 300m in height. As far as flat tops are concerned, he adds, the 24t or 30t categories are most in demand, with both jib lengths and heights of 70-80m. Linden Comansa’s most popular models in this category are the 25t 21LC550 and the 12t 16LC260. Over at NFT Al Zahlawi says the demand for Potain cranes is across all categories. “We are the Potain dealer for the entire GCC and have
been associated with them for almost 35 years. We are synomymous with the brand and offer all of their products. In the Middle East, where the higher capacity models are more popular, we see a god demand for the 40t MD1100 model. In fact, we have the maximum number of units of this model in the world for any crane supplier. The most popular Potain model in this region, however, remains the MC310 K12 with a 12t maximum capacity, which comes down to 3t at the tip of its 70m jib.” Speaking about the state of the market, Al Zahlawi says: “There was a time when 60% of our business was sales, with rental making up the remaining 40%. After 2009 those figures have flipped. With the uncertainty in the market at present, there is a high level of risk aversion and contractors are preferring to use the tower cranes on a project basis, rather than owing them outright and then having them sit idle when a project is over.” Liebherr, another giant of the sector, has also seen considerable traction in its 12t cranes. Speaking to media outlets in the region, Jens Kotzurek, Middle East sales director for tower cranes, has pointed out that the company has a major share of the region’s market with a total of around 700 cranes on the ground. It is most successful in the Qatari market where it claims to control more than 70% of the tower crane sector. Kotzurek explained that some 90% of the company’s tower cranes in the region were of the top slewing variety,

Though rare in the Middle East, projects in several parts of the world demand heavy lifting services from tower cranes and the Belgian company has a long history of crane services and heavy lift operations globally and in the region, including in the tower cranes sphere. “As a heavy lift solutions provider, we only focus on high-capacity tower cranes,” says Philippe Verdeure, Saren’s regional sales manager (projects) – APAC, Middle East & NAF. “Our fleet ranges from lift capacities of 50t to 126t. Some of our cranes are theoretically capable of reaching heights of up to 800m, which would of course require the proper base and for the crane tower to be anchored to the structure it is next to. Sarens’ special services “Lifting really heavy items with tower cranes is one of the special services that we provide. We have a long and successful track record of such operations in various parts of the world, such as in South Africa, England and Poland.” Verdeure explains that Sarens is the goto company where heavy industrial lifts are concerned and most of the heavy lift work it has done with tower cranes has been in the industrial and power sector. “We are busy in South Africa with erecting a super-tall solar tower for energy production, among other global projects. A lot of our projects are in the power and renewable energy sector,” he points out. “While large renewable energy projects are not common in the Middle East, our cranes are best suited for power plants in other geographies where space is at a premium and the area of power plants and installations is narrower and more confined than in similar projects in the Middle East, which means a fixed heavy duty tower crane is greater value for money. Here in the ME, the area allocated to the conventional power projects is so vast and wide that a very tall, high-capacity crawler crane can be quite useful.” Sarens does have several notable lifts to its credit in the Middle East, and Verdeure points out two of them: “Sarens recently successfully performed a heavy lift project in Kuwait where we used a 3,600t capacity gantry crane system for a record heavy lift operation and also used cranes ranging from 50t to 1600t in the same project. We also have an ongoing project in the Jizan, Saudi Arabia, which is the largest air separation unit in the world.”
Luffing-jib tower cranes are popular on projects where space for the jib to swing and manoeuvre is at a premium, such as in urban and industrial settings.
In the event that very heavy loads need to be lifted very high with a fixed crane, Sarens’ heavy-lift tower crane services will prove invaluable, he adds. Looking ahead, most market players believe that in the short-term growth will come in pockets, such as from Doha’s Wold Cup projects and Dubai’s Expo 2020. Al Zahlawi says: “The entire Middle East market is down but with the Expo 2020 and
Dubai’s commercial ambitions significant growth is expected in the construction sector for the next few years. Qatar too is progressing apace on must-deliver projects while Kuwait has the fiscal reserves to grow.” For the longer term, the region remains a place with a potential that is enormous enough for the tower crane market to hunker down and weather the present doldrums in order to realise it.

ime was when cleaner and greener technologies were not really things that overly concerned the Middle East’s construction equipment sector. The odd large contractor might include a one-off ‘green machine’ in his fleet as lip service to environmental concerns, but that was largely it. And with much of the construction boom concentrated on outdoor building activity as the region’s cities went about ramping up their infrastructure and erecting grand buildings, there was no practical need for cleaner machines. All that is changing. The past decade has seen breakneck construction activity, and the transformative effects mean maintenance of the already built-up structures is now of as much importance as building new ones. In this scenario, machines designed for maintenance work, such as powered access equipment, aerial work platforms and hoists, have become as important as the big earth movers, excavators and cranes. And when that maintenance work has to go indoors, as it is naturally bound to, the only option is equipment with no emissions – in other words, all-electric machines. Harnessing today’s latest technology to combine cost-efficient, cleaner and quieter continuous indoor and outdoor operation with improved robustness, reduced maintenance costs and increased versatility, the new generation of all-electric Genie boom lifts open the door to new opportunities for operators and rental companies. Keeping in mind the requirements of the rental sector, which requires machines that can service both indoor and outdoor needs, the Terex Group company has introduced new models that provide the power and performance of diesel in a zero-emission electric package fit for indoor use. Charbel Kordahi, managing and sales director of Terex Middle East, says: “Representing as much as 80% of rental sales in some cases, business potential for indoor and outdoor applications in the 12-20m range is high, but the global product offering in this segment is limited to either heavier compact electric units adapted to indoor tasks or diesel machines for outdoor applications. This observation spurred the development of our revolutionary new generation of ‘2-in1’ Genie machines that allow operators to work indoors and outdoors with a single

unit without sacrificing drive performance to provide high rates of machine utilisation. Easy to operate, productive and cost-efficient to own, these machines allow operators to perform more tasks with one machine and offer rental companies the opportunity to rethink the way they manage their fleets.” Insights into the Genie brand’s pioneering new all-electric Genie Z-33/18 and Genie Z-60/37DC boom lifts, and the new perspectives they offer rental companies and end users, reveal how customers in the Middle East have found the machines suitable for various tasks and applications. Rental champion In 2016, Dubai rental company AJI Heavy Equipment Rental received delivery of six Genie Z-33/18 booms lifts. Describing the benefits of the machine, Dean Jones, general manager of the company, says: “The Z-33/18 boom is so versatile that our machines are under constant demand and providing excellent returns of investment. One of the foremost features in the machine is the operating speed battery life, which is far superior over its competitors and sets this machine apart.” “We also find the maintenance-free design of its power system, which integrates the motor, brake and gearbox all in one unit, very practical. And since there are no brushes to
replace or commutators to service, time in the workshop is reduced. As a result it spends more time in the field. It is also simple to use and operators love it.” Genie describes the Z-33/18 as a simple, robust electric unit powered by an efficient three-phase AC electric drive system. The company says it requires less energy while offering longer battery cycles, in addition to the benefits of quiet, zero emissions performance and ease of operation. It is able to drive longer distances, needs to be recharged less often and costs less to maintain than units equipped with a DC transmission. With its broad field of application, the Genie Z-33/18 boom lift combines all the benefits that rental companies need to boost rental rates and return of investment. With the ability to perform a full day’s work – both indoors and out – on a single battery charge, the Genie Z-33/18 lift is significantly lighter than traditional machines in the 12m category. Weighing just 3,640kg, nearly 1,500kg less than other electric-powered units, this model boasts a total occupied floor pressure of only 991kg/sqm and a low tyre contact pressure of 483kPa. As a result, the Z-33/18 boom is an ideal solution for applications on fragile indoor surfaces where reduced floor load is paramount, as well as for outside duties, even on wet grass or freshly stabilised ground. Further enhancing its versatility, to avoid damaging sensitive outdoor surfaces and turf, the Z-33/18 boom is available with standard solid rubber non-marking or optional multisurface non-marking tyres. According to Kordahi, it is well suited to an extremely broad field of routine outdoor maintenance and indoor applications, and ideal for industrial and warehouse facilities, airports, shopping centres and theatres, where space is tight and floors are fragile. Facilities management duties such as window cleaning, installation, replacement and verification of lamps, signage, electricity, sprinklers and security cameras are among the many other applications that make this multi-tasking machine such a profitable investment. Kordahi adds that operators, including newly trained ones, find that besides being able to switch between indoor and outdoor duties all day long with a single machine, the fact that this simple, lightweight unit does not have a jib makes the Z-33/18 boom much easier and efficient to work with. “Added to its short turning radius, zero turntable tail swing and FastMast system that reduces ground to top lifting time at the push of a button, operators find this machine better suited to many routine tasks,” he adds.

“We designed this innovative all-electric boom to offer customers the right equation of maximised range of motion, real four-wheel drive abilities, quiet performance, energy efficiency, jobsite versatility and cost effectiveness” Resorting to all-electric The Genie stable also includes the Z-60/37 DC boom, another model that has found favour in the region. Three of these machines are currently assisting in the extensive maintenance work required at one of the region’s biggest entertainment and leisure destinations, Dubai Parks and Resorts. Comprising three theme parks and a water park over an area of 325,160.64sqm – equivalent to 420 football fields – Dubai Park and Resorts is set to be the largest integrated leisure destination the Middle East has ever seen. To handle maintenance duties, which are extremely varied due to the multiple themes and nature of the site, Al Mahroos, Genie’s authorised distributor in Dubai, recommended three all-electric Genie Z-60/37 DC booms, which were delivered in January this year. Speaking about clinching the deal for the Genies, Nishad Abdulla, assistant fleet manager, Dubai Parks and Resorts, says: “We are always looking for new solutions that suit our needs in terms of productivity and the quality of work-site conditions. Thanks to its excellent range of motion, versatile, quiet, clean performance and four-wheel drive abilities, this new Genie model is an excellent and cost-effective alternative to

separate diesel and electric powered units. For us, the Z-60/37DC boom definitely ticks all the right boxes. “Offering the ability to adapt to our broad spectrum of architectural styles, its narrow footprint, four-wheel drive capabilities and all-terrain, non-marking tyres are an excellent match for work outdoors on rough ground and indoors on fragile surfaces where space is often limited. And since part of the resort is already open to the public, low noise levels and emissions-free operation are an absolute must-have that allow us to operate these machines all day without disturbing visitors.” Offering the advantages of zero emissions and full workday operation on just one charge, the new articulating Z-60/37DC boom is ideal for indoor and outdoor applications such as industrial plants, malls, convention centres and construction sites, Genie says. Thanks to fast recharging offering a full charge from a 110V/220V wall power supply in less than 12 hours, operators have a very productive machine. The zero-emissions capability of the Genie Z-60/37DC boom lift should by no means be underestimated. Powered by high-efficiency sealed three-phase fully enclosed AC electric drive motors and able to operate submerged
in up to three feet of water, this robust 4WD drive machine is able to go 25% faster and climb slopes as well as its diesel-powered counterparts. Equipped as standard with allterrain, non-marking tyres, it features the same active oscillating axle system as many other diesel-powered Genie machines to offer a similar all-terrain performance. Adam Hailey, director of Product Management at Terex AWP, notes: “We thoughtfully designed this innovative allelectric boom to take advantage of the strengths and history of our boom lift product line, to offer customers the right equation of maximised range of motion, real fourwheel drive abilities, quiet performance, energy efficiency, job-site versatility and cost-effectiveness.” “Weighing 2,268kg less than the Z-62/40 boom lift, the new Z 60/37DC enhances the efficiency of this new all-electric concept. This means that, while providing the ability to access many indoor and outdoor work environments that other models cannot, this boom lift is able to run all day. In addition, the torque and drive systems work together to perform more efficiently than a hydraulic powered machine, using 30% less energy than normally required.”
