RECOVERY ON TECH While curating this edition of CMME, what stood out for us is how the ongoing recovery we see in the regional market - albeit yet to gather real pace – is predicated on the use of technology like never before. Time was when the Middle East machinery sector treated things such as telematics, machine monitoring and remote-controlled equipment operation as new-fangled fads that happened in other regions of the world. When it came to working on the sandy dust bowls of the region’s job-sites, operators, fleet owners and contractors all swore by the simple analogue, uncomplicated, easy-to-fix stuff. But now that seems to be changing. Whether due to the effects of the social distancing and other restrictions imposed by Covid-19, more and more machinery operators in the region have had to resort to some sort of digitalisation. Prime among these is remote monitoring and diagnostics, as exemplified by such recent developments as Volvo opening its regional Uptime Centre for the Middle East in Dubai in the last 18 months. When we spoke to bulldozer manufacturers for our cover feature this month, we found a willingness to discuss technological aspects of their products and services that we hadn’t seen before. For example, Komatsu, which has pioneered some of the leading-edge remote-controlled operations technology for bulldozers in the world, is eager to show how the systems work and how they can be relevant for the Middle East, even though they are not available here at the moment. The company does sense an opportunity, though, and feels altered work patterns due to the impact of the pandemic could make these technologies relevant for the region. The latest in the world of machinery typically used to by-pass the conservative

Middle East job-site, but this may no longer be the case going forward. Another case in point is Haulotte’s new Pulseo electric scissor lifts, which we look at in this issue. Machines such as these are now asked for quite often on our job-sites and electric equipment is becoming just as normal for the access sector here – albeit for indoor use – as it is anywhere else in the world. These new regional trends are no surprise in another sense as well, and not just as a fallout of the pandemic. Many GCC cities and territories have often been early adopters of a lot of new global developments in their penchant to be the first, best or biggest in the world. In the field of construction, 3D printed buildings and structures come readily to mind. Dubai, for example, already has the world’s largest 3D printed concrete building and has plans to have a significant percentage of its new builds 3D printed within the next few decades. In this context, an academic expert from the Herriot-Watt University tells us in this issue about the pros and cons of 3D printed construction and muses about the way ahead. That way ahead, though, is digital on the whole. And we will continue to watch with interest how the post-Covid recovery in the region has digital underpinnings.

Johnson Arabia goes on expansion drive Johnson Arabia has announced a simultaneous expansion of its regional geographical footprint and its aerial work platform (AWP) fleet, augmenting its number of units with 112 new AWPs, most of which will be deployed in its new location in Muscat, Oman. The regional equipment rental powerhouse said it is soon to take delivery of the 112 new machines, which will complement its existing fleet across the group. The delivery will comprise the latest models from the two leading access equipment manufacturers JLG and Genie. The units will start to arrive this month and continue to arrive in batches over the next three months. The company said that after successfully navigating the tough markets in 2020, it has proved to be a

leader in the rental industry and is now expanding its fleet. This investment strengthens the company’s ambition to get to a fleet size of 1,000 machines by the close of 2021. The majority of the purchased machines will be delivered to the new Johnson Arabia locations in Muscat and an existing location in Duqm, with the remaining units delivered to their headquarters in the UAE, to help meet growing demand. Gareth Conley, executive manager for AWP, said: “In spite of the dip in utilisation in 2020, we are seeing a higher demand in the market. Along with the UAE, we have also welcomed an increase in requests in Muscat and Duqm in the oil & gas and construction sectors. This increase in fleet is to not only supplement this demand but to also increase our footprint in Oman.”

COMBILIFT LAUNCHES ELECTRIC AISLE MASTER-OP

Marketplace-E sees 28% rise in demand

Marketplace-E, the online platform for buying and selling surplus heavy equipment, has recorded a surge in bidder activity in 2020 from buyers across the Middle East and Africa, according to global equipment auctioneer Ritchie Bros., the owners of the platform. Demand for heavy equipment on the platform increased by 28% last year when compared to 2019’s figures, said Ritchie Bros., as

HAULOTTE SEES FALL IN REVENUE Haulotte has reported a 27% fall in revenues for 2020 owing to Covid-19. Revenues were €439.6m in 2020 compared with €610.8m in 2019, with €114.5m achieved in the last quarter, down 12% year-on-year but up 13% over Q3 2020.

construction companies increasingly turned to online marketplace platforms to search for more convenient asset disposition and purchasing alternatives during the Covid-19 disruption. Phillip Weston, key accounts manager, Ritchie Bros. Middle East, said: “This upsurge is predominantly due to factors such as countrywide lockdowns and global travel restrictions, which are making

attendance at traditional, live auction events more difficult. Furthermore, a shift towards online auction solutions was already underway before the pandemic, which has exponentially sped up its popularity.” Marketplace-E operates in several sectors, including construction, transportation, agriculture, energy, oil & gas and mining as a subsidiary of Ritchie Bros., the world’s largest heavy equipment auction company. According to Ritchie Bros., the online platform operates a reserve price, 24/7 online service, offering customers endto-end asset management solutions that over the years have helped organisations sell and buy machinery, heavy equipment, trucks, and other industrial assets.

JCB hires on post-Covid recovery

JCB will recruit 400 new personnel in its UK production facilities and award permanent contracts to existing agency staff as it gears up “for a surge in production”. The British equipment giant said the decision was based on a “sharp rebound” in

the construction equipment market since production was brought to a halt by the Covid-19 pandemic last year. Not only will the Staffordshirebased company recruit more than 400 extra agency staff, but it will also give permanent contracts to up to 300 existing

agency staff in addition to the new recruitment. According to JCB, 2021 has “started strongly” and the new jobs it is recruiting for are in a variety of shop-floor roles including assembly, welding and forklift truck drivers. The news follows

heavy redundancies last year due to the pandemic. Mark Turner, chief operating officer, JCB, had earlier said that orders “disappeared overnight” in March last year, when the pandemic struck. He was quoted in the UK media as saying that “regrettably many staff positions were impacted”. “It took more than six months for the business to recover to production levels we last saw in March 2020. This year has started strongly, and our forecasts predict a continued solid recovery, with strong demand from mainland Europe and North America. After a tumultuous 12 months, this really is good news,” Turner was quoted as saying.

Doosan Infracore has surpassed the 200,000 mark in the cumulative production of excavators in China, a first among all foreign companies operating in China. Doosan announced that its Chinese subsidiary, DICC (Doosan Infracore China Corporation Co., Ltd.), located in Yantai, China, has produced its 200,000th excavator in the country, which came some 26 years after establishing its presence in the country. To mark the achievement, Doosan China invited employees, dealers and

customers to its Yantai plant and held a ceremony to celebrate the production of the 200,000th unit in China. The event, which was broadcast live online, featured the handover ceremony of the landmark excavator to its customer. Doosan said it is the first MNC operating in China to achieve the impressive cumulative production figure. The company has steadily strengthened its market share from 12.9% in 2015 to 22.8% in the third quarter of 2020 in the Chinese market among MNC brands.

CHOICE FOR OPERATORS

SNORKEL MAKES OPEN CABS AVAILABLE ON TELEHANDLERS

Hareket UAE lift uses Enerpac strand jacks

Turkish heavy lifting company, Hareket, relied upon Enerpac strand jacks to install superheater and vaporisation modules at the UAE’s first waste-to-energy (WTE) facility in Sharjah. Hareket said it undertook all heavy lift engineering and supervision of the strand jacking works at the project. This involved installing two temporary lifting platforms, each featuring two Enerpac 200t-capacity strand jacks per platform. The strand jacks were used to lift eight 77t superheaters and two 20t

vaporiser modules up to 30m. Accurate positioning of the 16m high modules was synchronised by a single operator using a wireless controller on each platform. Samet Gürsu, operations director, Hareket Heavy Lifting & Project Transportation Co., said: “This was our first deployment of the Enerpac strand jacks, and they performed very well, demonstrating the flexibility and innovation that Hareket brings to heavy lift projects where traditional lifting methods are impractical.” The 200t capacity Enerpac strand jack acts like a linear winch. A bundle of steel cables or strands are guided through a hydraulic cylinder; above and below the cylinder are anchor systems with wedges that grip the strand bundle. By stroking the cylinder in and out while the grips are engaged in the anchors, a lifting or lowering movement is achieved. The motion of the cylinders is driven by hydraulic power packs.

Liebherr introduces new 700t crawler Liebherr has introduced the new LR 1700-1.0 crawler crane, which combines the benefits of economical transport of the 600t-class crawler cranes with the performance of a 750t-class lattice boom crane and also features all the innovations of Liebherr’s crawler crane developments from the last few years. The company said the design of the new LR 1700-1.0, which has a maximum lifting capacity of 700t, is based on its 600t predecessor, the LR 1600/2 crawler, which has seen over 200 units produced over 12 years now. Liebherr said it has completely redesigned the base machine for the new LR 1700-1.0 based on the dimensions of the LR 1600/2. Its track width is slightly larger than its predecessor at 8.7m, while the length of the crawler carriers has grown to 11.35m. The LR 1700-1.0 is available with Quick Connection as an option. This means that the transport weight of the slewing platform (without

the SA frame and winches) can be reduced to around 42t, well below the limit of 45t to ensure low-cost heavy haulage. The same applies to the crawler carriers which, with their 2m crawler pads and four-fold drive, weigh in at just 43t. This guarantees that the new 700t crane can be transported at low cost. The width of the various components is another important criterion for economic mobility and Liebherr said that here too, the LR 1700-1.0 has all the transport units for the base machine, including the pivot section, at no more than3m in width. Only the H lattice sections on the main boom are wider than this at 3.5m. However, these can be used to transport the smaller sections to reduce the number of transport vehicles required. For customers in countries where transport widths of over 3m are not possible, Liebherr can also supply the boom for the LR 1700-1.0 exclusively with 3m-wide lattice sections.

DEMAG IN TIGHT TURIN LIFT

talian cities are famous for their picturesque centres with narrow, winding streets. But as much as tourists love this, it can be a nightmare for projects that require heavy equipment, as was recently the case when crane service provider Calabrese Autogru lifted a heat exchanger in the middle of Turin. A compact but powerful crane was needed for the project, which is why Calabrese Autogru S.r.l., a company that specializes in heavy lifting, chose to use the Demag AC 160-5 all-terrain crane. Managing d i re c to r Alessandro Calabrese says: “To be perfectly honest, we didn’t even consider anything but the AC 160-5 for this project. I simply don’t know of any other model in this class that could have done a better job of handling the tight space constraints at the site.” Even accessing the site proved to be challenging: despite parking being prohibited, several vehicles were parked along the access road, reducing the effective width of the road to less than 3m. For most other cranes in this class, the project would

have ended right there. Not for the Demag AC 160-5, however – with its width of only 2.75m, all it took was a bit of skill from the crane operator to manoeuvre in between the parked vehicles and get the crane to its destination. Once on site, the crane was able to put another substantial advantage to work: thanks to its 68m telescopic boom, it was able to perform the lift immediately, without the need to attach an extension. “In that narrow road, setting up a main boom extension would have been both time-consuming and logistically challenging, and that would have resulted in significant extra costs. The AC 160-5 saved us from having to go down that route,” Calabrese adds. At that point, the crane was ready to lift the 7.2t heat exchanger without any further difficulties – or so you might think. Instead, one more obstacle common to urban projects awaited the team: “The hook block and slinging gear added one tonne to the weight of the load, which meant that our AC 160-5 had to lift a total of 8.2t,” Calabrese explains.

Under normal circumstances, this would not have been a problem for a machine in this class, but in the narrow Turin street, things were a bit different: the parked cars made it challenging for the AC 160-5 to extend its outriggers. The sidewalk could not be used as a support either, as it did not have enough load capacity to support the pressure from the outriggers due to underground cavities. “This meant that we were only able to extend the outriggers to a limited degree and in an asymmetrical configuration,” Calabrese says. “However, we were able to go ahead with the lift thanks to the IC-1 Plus crane control system, which precisely determined the maximum possible load, taking all relevant factors into account before giving us the green light.” This enabled the Demag AC 160-5 to smoothly lift the 7.2t heat exchanger through a radius of 19m with the telescopic boom fully extended, and bring it to a height of 35m before setting it down at the location intended for it.

PRINTING THE FUTURE DR. MUSTAFA BATIKHA, ASSOCIATE DIRECTOR OF RESEARCH AT THE HERIOT-WATT UNIVERSITY DUBAI’S SCHOOL OF ENERGY, GEOSCIENCE, INFRASTRUCTURE AND SOCIETY, DISCUSSES THE PROS AND CONS OF 3D CONCRETE PRINTING AND THE WAY AHEAD

rapidly growing population is one of our biggest challenges in the 21st century. Recent data from the United Nations confirms that the world’s population will reach 9.7 billion in 2050 with an average yearly increase rate of 0.84% between 2010 and 2050. With this population growth, it is predicted that the global construction industry will record a compounded annual growth rate (CAGR) of 5.7% to reach about $12tr trillion by 2024. Governments around the world are under enormous pressure due to a shortage of affordable housing. For example, the UAE government has taken the initiative of launching The Emirates Development Bank (EDB) with $2.7bn aimed at financing affordable residential projects for UAE citizens by 2021. On the other hand, there is a demand for addressing important issues in the construction

sector, such as sustainability and health and safety, in the backdrop of rapid and cost-effective construction. Thus, the construction industry is in need of new innovative construction technologies such as 3D Concrete Printing (3DCP), which is paving the way for meeting future requirements. Understanding the technique 3DCP was developed to build a structure upwards through a series of layers, one on top of another through a robotic arm or a gantry girder system. The concrete material in this technology is the printer’s ink, while a nozzle attached to the printing system plays the printing mechanism’s role. The final output is a layer of concrete of the desired shape and thickness. Printer selection plays a vital role in terms of cost and printing quality. For example, the robotic arm offers better flexibility since it has six degrees of freedom. It also allows superior quality in printing for precise, complex printed shapes. Its limitation is the limited arm length. Also, the operation and maintenance of the robotic arm make printing cost

higher than the gantry girder by about three times. The robotic arm’s biggest disadvantage is that the printer has an unstoppable process until the element is fully printed. Therefore, design errors will produce material wastage. However, the selection of the printer is defined based on the printed structure’s type. Advantages of 3DCP 3DCP in construction avoids the disadvantages of in-situ reinforced concrete (RC), such as excessive construction waste, formwork cost (which comprises more than 60% of the overall cost), formwork preparation time (which takes up 50% to 70% of the total construction duration), and the lack of worker health and safety (where workers’ injuries in in-situ RC construction are double the accidents registered by other industries). WinSun, a pioneer of 3D printing technology in construction, claimed that the labour cost of their ‘Office of the Future’ project in Dubai was reduced by more than 50% when compared to conventional buildings of similar sizes.

15 The world’s largest 3D printed building is a two-storey, 640 square metre, one completed in 500 hours by Apis Cor for Dubai Municipality. The city wants 25% of new buildings 3D printed by 2025.

Compared to Precast Concrete (PC) construction, 3DCP is more economical and sustainable, although PC is faster in terms of construction duration. A recent study by Heriot-Watt University also confirms that 3DCP reduces cost by 39% and CO2 emissions by 48% compared to PC. There is a high percentage of steel reinforcement in precast concrete, which results in high CO2 emission in the manufacturing process of the steel reinforcement produces. Besides, the formwork manufacturing process in precast consumes energy, although the formwork can be reused 75 times. The globality of 3DCP Globally, projects implemented using 3DCP include the Rain Collector of 2.15x2.20x2.6 m3 completed within nine hours by XTreeE; the Icon House of 33m2 within 47 hours by Austin Texas; a 38m2 villa within 24 hours by Apis Cor company; a two-storey structure of 400m2 by HuaShang Tengda within 45 days; Dubai’s 250m2 Office of The Future completed within 17 days by WinSun Global; and a two-storey office of 640m2 – the world’s largest 3D-printed

building – completed for Dubai municipality within 500 hours by Apis Cor. 3DCP will make further progress, thanks to Dubai’s ambitious plan to 3D-print 25% of the city’s new buildings by 2025. Challenges facing 3DCP Looking at the current and future challenges facing 3DCP, various solutions might need to be adopted. To date, no official codes and standards for 3DCP design have been outlined by the authorities. Therefore, research is critical into supporting the issuing of a design standard for 3D printing. The concrete material used in printing has a relatively high cement quantity, making it costly and not sustainable. Developing this material by using recycled substances will reduce the cost and significantly improve sustainability. The structural configurations of the printed elements need to be studied and confirmed for economic design and energy savings. Additionally, printing roofs and elements under bending with a low steel reinforcement percentage needs further research as well.

Currently, printed buildings are capable of only rising to one or two storeys with steel reinforcement addition. The challenge of the future is to make 3DCP more suitable for multistorey buildings under different action scenarios. The use of 3DCP for segmental precast construction requires more intensive research in order to be used in large structures. The connections among segments need to be studied to confirm high performance and low maintenance during their life cycle. More research and development is required to make the 3DCP printer more flexible and efficient. At Heriot-Watt University, the Centre of Excellence in Smart Construction (CESC) researches subjects such as ‘Productivity and Performance’, focusing on technologies that improve the construction industry’s efficiency. The CESC established a special team in 2019 for research in the area of 3DCP and many research dissertations at Heriot-Watt University are currently focused on finding solutions to the problems of 3DCP.

SETTING HIGH STANDARDS PASMA, THE REGULATORY BODY DRIVING SAFER PRACTICES FOR WORKING AT HEIGHT, HAS BEEN DRIVING SAFETY FOR CONSTRUCTION WORKERS IN VARIOUS REGIONS OF THE WORLD, INCLUDING THE MIDDLE EAST. CMME ASKS SARAH NUNN, HEAD OF INTERNATIONAL DEVELOPMENT, ABOUT THE BODY’S ACTIVITIES AND INITIATIVES

orking at heights is a fact of life for most types of construction and for many aspects of routine maintenance work. Yet of course, with height comes risk, not least because there’s a greater reliance on the security of the working platforms being used. Scaffolding - while immensely useful has the disadvantage of being potentially insecure: it has to be erected following strict protocols and the workers using it must know how to enter, exit and navigate the structure safely. So - the need for a dedicated industry body. PASMA is the international not-for-profit association for the mobile access tower industry. Representing the interests of manufacturers, suppliers, specifiers and users, it provides and oversees the industry standard training scheme and is a major publisher of safetyrelated knowledge, information and guidance. It represents the interests of members in the UK, the Middle East, South Africa and SE Asia.

17 PASMA was founded in 1974 and solely represents the mobile access tower/scaffold industry. Part of its mission statement is to care “about the people that use them”.

“We have also engaged with and collated the guidance issued by the World Health Organisation and various government and other bodies to create a Covid support hub on our website: This hub is aimed at supporting our members as well as the public in how they can make use of mobile access towers while adhering to guidance”

INTERVIEW M ARCH 2021

We spoke to Sarah Nunn, PASMA’s head of International Development, about its critical industry role and the guidance and training that it provides to make working at height a considerably safer activity. Can you tell us about PASMA as an official body and its purpose, activities and objectives. How is it useful to the workat-heights sector? The Prefabricated Access Suppliers’ and Manufacturers’ Association (PASMA) was founded in 1974. We solely represent the mobile access tower/scaffold industry, as reflected in our mission statement - “we are the organisation that knows mobile access towers and cares about the people that use them”. The association supports the interests of all concerned, from standard setting, manufacture and supply through to training and the end user. Tower information is available at a level to suit everyone from first-time users to major contractors. PASMA also provides industry-standard training, which has gained international recognition and is growing across the GCC with thousands of delegates being trained annually. PASMA plays a major part in promoting mobile access towers for temporary work at height - not just in construction and building maintenance, but in facilities management, the local government sector and retail. Plus, taking part in conferences, seminars and workshops is an essential part of the association’s educational remit.

“As with all parts of the world, work at height remains the biggest cause of avoidable workplace accidents leading to fatalities and injuries”

PASMA’s special ‘Working Towards’ membership level for GCC manufacturers looking to gain EN1004 product conformity, helps those who are committed to the certification.

What are PASMA’s activities in the GCC region? Please give us an overview and mention some key initiatives taken in the region. PASMA has been actively working in the GCC region for approximately eight years and has provided support to standard-setting bodies and regulators such as Dubai Municipality, OSHAD, Government of Sharjah, PDO and OPAL during their development of Working at Height Standards. Each year, PASMA organises a Tower Safety

Week and works with members locally by engaging with major projects and delivering Tool Box Talks and safety briefings. PASMA has supported many organisations across the GCC by training their trainers to deliver the PASMA portfolio of training courses and supplying equipment that conforms to product standard EN1004. To support local manufacturers in the GCC to gain product conformity certification to EN1004, PASMA created a Working Towards level of its membership which allows members to demonstrate that they are committed to obtaining certification and are actively working towards it. PASMA provides support and guidance to these members on all vital areas such as their instruction manuals, quality management system requirements, when to engage with a 3rd party test body and how to put together their technical file for submission. How is work-at-height safety treated in the region and how is it improving? What role is PASMA playing in this? In general, the standard for safe work at height has developed and improved over the last eight years. It’s fair to say that both the regulators and the project developers are working hard to ensure the safety of those working at height. The international interest in the major projects in the region such as EXPO 2020 and FIFA World Cup 2022 has brought with it improvements. PASMA works directly with the regulators such as Dubai Municipality, PDO, Ashghal and others in improving standards. There are more and

19 more people trained in the safe use of mobile access towers and we believe this training provides both the users and the managers with information and skills that significantly help raise standards for work at height. What has PASMA’s response been to the Covid-19 crisis? What impact has the pandemic had in the sectors you operate in and what measures have been taken to mitigate this? Has safety suffered at all under the effects of the pandemic? PASMA has developed an E-learning package to cover theory elements of training which delegates can undertake through approved training centres; they then complete the practical session at the centre while adhering to social distancing protocols. Instructor training and upskilling packages have now been converted and made available virtually; these have proven popular globally as they support social distancing requirements by eliminating the need for physical interaction. We have also engaged with and collated the guidance issued by the World Health Organisation and various government and other bodies to create a Covid support hub on our website: This hub is aimed at supporting our¬¬¬ members as well as the public in how they can make use of mobile access towers while adhering to guidance. During the summer months, we saw a substantial interruption to training with delegate numbers decreasing virtually to zero. Numbers are now increasing, and we are on the same trajectory as we were pre-Covid. Sadly, with focus turning to the protection of people from Covid, it’s quite possible that safety when working at height has suffered. In the early days, however, we received many calls from members asking how they can deliver training and how towers can be used in a socially- distanced setting. How do workers in the sector obtain a PASMA certificate and how does it help them, in practical terms? To obtain PASMA certification, personnel can contact any of our approved training centres in the GCC or locate one via the PASMA website. The User level course (Towers for Users) will equip delegates with the skills to assemble, inspect, alter and dismantle a mobile access tower. The Manager level course (Towers for Managers) will teach those who manage/ supervise a team working at height and ensure they’ve selected the most appropriate form of access for the task at hand. There are another eight courses within the portfolio, covering an introduction to work

A PASMA Tower for User training course is one day in duration and will consist of a theory and a practical session. The theory session is first and takes delegates through local legislation, regulations, product standards and the PASMA Code of Practice. During this session, delegates will cover the specifics of tower components, types of hazards, what can go wrong and how to mitigate against these risks. A theory assessment will then be conducted under exam conditions to verify learning and understanding: delegates must pass this in order to move onto the practical session. During the practical session, delegates will gain hands-on experience in assembling mobile towers and will again be assessed during the exercise. In the event that anyone puts themselves at risk of a fall, it will result in an automatic failure.

at height, specific configurations of towers such as cantilevers, bridge towers, stairway towers, along with our vocational training of Access Tower Specialists. All tower training within PASMA’s portfolio incorporates ‘fall prevention’ into the build and dismantle process as well as the final structure - keeping everyone safe throughout the lifecycle of the build and use. Please guide us through a PASMA training, describing the aims, process and testing.

How do you see the future of the work-atheights/access sector in the GCC and what role do you see PASMA playing? As with all parts of the world, work at height remains the biggest cause of avoidable workplace accidents leading to fatalities and injuries. PASMA has taken a lead role in work at height safety through several initiatives and we see a complete elimination of falls from height and accidents in the future. We understand that this will take time, but working with all stakeholders we are already seeing a reduction in the number of falls from height. There is also a real improvement in the commitment to increase safe work at height practices.

EN1004 GUIDELINES

A CODE FOR ELEVATING SAFETY PASMA sets the standards of safe working at heights by ensuring that the guidelines of the important EN1004 safety standard are followed at all times. Here is a keynote summary of what’s involved: • EN1004 certified towers have the right quantity of purposedesigned platforms, supplied with the tower, which can be securely fitted and are provided with safe trapdoor access. They are not makeshift affairs made from bits of scaffold board or DIY pieces of plywood! In an EN1004 tower you will be supplied with sufficient platforms to install them at 2m intervals during assembly and dismantling.

• EN1004 towers have stabilisers supplied as part of the tower and not offered as accessories. Mobile towers must be fitted with stabilisers when used freestanding. • They have safe access - EN1004 towers have built in access equipment with safe distances between the rungs, and slipresistant climbing surfaces. You must never climb up the outside of a tower or lean a ladder against it to gain access to the platform. If you do, then the tower will become very unstable and will overturn. • EN1004 towers have safe guardrails. Note - never work on a platform without guardrails.

The guardrails of EN1004 towers meet the minimum height requirements at all points around the platform. • They can be assembled and dismantled safely. There are only two recognised safe systems of building and dismantling scaffold towers. The key rule in both is that you must never stand on an unprotected platform - that is a platform which is not fitted with guardrails around all the edges. The two safe systems are called: 3T (Through the Trap) and AGR (Advance Guardrail). EN1004 towers are specifically designed so that they can be built using one of the two methods.

JCB ENHANCES TELEHANDLERS WHY GET IT? UPDATED ENGINES OFFER MORE POWER MATED TO NEW EFFICIENT TRANSMISSION JCB is launching a new range of Loadall telescopic handlers featuring more powerful engines and offering the unique DualTech Variable Transmission on additional models. The award-winning transmission, which combines hydrostatic drive for low speeds and powershift mechanical direct drive at faster speeds for enhanced performance and versatility, is no longer reserved for the topspecification Series III Loadalls. It can now also be specified for the smallest full-size Loadall – the 532-60, said the manufacturer. The new large-platform Loadall updates include: 109, 130 and 150hp outputs for the AGRI, AGRI Super, AGRI Xtra specs; DualTech VT now available in more models; 40kph top speed capability now standard on 6m, 7m and 9.5m models; new Auto Stop feature discourages fuel wastage on idling engines. “DualTech VT has been immensely successful and popular in our top-spec agricultural Loadall and now we are making it more accessible to a wider range by adding it to the AGRI Super equipment package and to our 3.2t, 6m 532-60 introduced in early

2020,” said John Smith, JCB agriculture MD. “User experience and data from our LiveLink telematics system has confirmed our view that this uniquely versatile and capable transmission increases productivity and improves fuel efficiency. It’s also a pleasure to use and really does offer the ‘best of both worlds’ characteristics of hydrostatic and powershift drive.” The latest JCB Loadall handlers are powered by 4.8l JCB 448 DieselMAX engines with a compact package of exhaust after-treatment technologies to meet EU Stage V emissions compliance and power outputs that relate to the AGRI, AGRI Super and AGRI Xtra specification levels. In AGRI models, the engine has unchanged ratings of 109hp and 516Nm torque; for AGRI Super versions, there is an extra 5hp at 130hp along with 550Nm of torque; and for AGRI Xtra models the engine also has an additional 5hp at 150hp but also a 7% increase in peak torque at 600Nm for livelier performance.

LEICA-READY KITS FOR DOOSAN EXCAVATORS WHY GET IT? TILT BUCKET AND TILT ROTATOR AUTOMATION ENABLES LESS EXPERIENCED OPERATORS EXECUTE COMPLEX TASKS Leica Geosystems and Doosan have released a new Leica-ready factory kit for the Doosan DX255LC-5 excavator with the new semiautomated excavator functionality. The new technology solution meets the increasing demand for machine guidance systems from excavator customers and the ready kit from Doosan is for the Leica iXE2 2D and iXE3 3D excavator machine control solutions, which enable tilt bucket or tilt rotator automation for the Doosan 25.5t crawler excavator. Under the collaboration between Doosan and Leica Geosystems, the new factory kit enables customers to order their Doosan excavators pre-configured to be ready for the installation of the Leica 2D and 3D machine control systems. Also, the Leica-ready kit includes all the components needed to install the new semi-automatic functionality for the DX255LC-5 excavator directly from Doosan’s factory through Doosan Smart Solutions. The kits include all the components, such as main brackets, wires and sensors, required to make sure a piece of equipment is ready for the installation of the machine control solution and the semi-auto functionality, which gives customers the flexibility to install the complete system at a later date. Magnus Thibblin, machine control president, Leica Geosystems, said: “We offer semi-automatic systems for excavators, including tilt and tilt rotator bucket automation, Automatic Tool Recognition and CoPilot functions to help operators work with less fatigue and in higher comfort. The new semi-automatic functionality for excavators enables even less experienced operators to execute complex tasks.”

NEW CAT 657 WHEEL TRACTOR SCRAPER WHY GET IT? IMPROVED ELECTRONICS AND OPERATOR COMFORT WITH LOWER FUEL CONSUMPTION HELP RAISE PRODUCTIVITY AND LOWER COST Caterpillar’s new 657 Wheel TractorScraper (WTS) delivers low-cost earthmoving with faster cycle times and a 7% increase in fuel efficiency. The machinery giant said in a statement that the new model moves more material per unit of fuel burned, with improved onboard payload estimating accuracy helping optimise productivity. The largest open bowl scraper in the Caterpillar line, with a rated load of 46.4t, it now has a more spacious cab to boost operator comfort and efficiency in high volume earthmoving, highway construction and mining applications. John Gerhold, wheel tractor-scraper application specialist for Caterpillar, said: “This new 657 is the next generation of ultra-class material moving systems. It delivers improved productivity, safety and technology, which our customers can use to strengthen their business today — and it is equipped to grow with them to meet tomorrow’s requirements.” The 657 features on-the-go weighing through Payload Estimator, allowing the new WTS to achieve 95% load accuracy,

so operators more easily reach target load goals. Ground Speed Control lowers fuel consumption by allowing the operator to set the desired top speed, allowing the machine to find the gear that works best for the engine and transmission. The two-engine design includes the Cat C18 powering the tractor and Cat C15 in the scraper. Its Advanced Productivity Electronic Control System (APECS) allows the machine to better utilise engine power and torque, resulting in more material moved throughout the shift. The transmission features Electronic Clutch Pressure Control, which improves shift quality and fuel efficiency. New hydraulic disc brakes improve braking performance and reduce maintenance. The 657 WTS also has a 21% larger cab interior than the preceding model, the 657G, improving operator comfort and providing excellent visibility to the bail, cutting edge and bowl of the new 657. The air suspension comfort seat adjusts and rotates 30-degrees to reduce fatigue, while the new Advance Ride Management adjusts damping to match ground conditions, resulting in a smoother ride for the operator. Automatic HVAC temperature controls come standard for increased operator comfort. The new power access ladder enhances operator safety when entering and exiting the cab.

The 657 includes a new hydraulic ondemand fan that increases engine fuel efficiency. The machine also has draft-arm overflow guards, which prevent material accumulation between the draft arms and bowl sides. Ground-level access for fuel fill and all daily maintenance points increases service efficiency and safety to increase machine uptime. Integrated Payload Estimator and Cat Product Link technologies provide real-time payload, machine location, fuel usage and idle time information as well as diagnostic fault codes—all to significantly increase fleet management efficiency.

JEKKO INTRODUCES JF545 V-MAX SPIDER CRANE WHY GET IT? NEW FLAGSHIP MODEL INCREASES VERSATILITY AND TOOL USE CAPABILITY WITH INDEPENDENT HYDRAULIC CIRCUIT Jekko has introduced it’s the JF545 V-Max articulated crawler crane that improves on the versatility and multitasking characteristics of its previous flagship, the JF545. The Treviso-, Italy, based manufacturer said the distinguishing feature of the new JF545 V-Max is a jib fitting a wide range of tools whose operations require elevated quantity and pressure of oil, such as an auger, a grapple saw or a clamshell bucket. An additional and independent hydraulic circuit with cooling radiator prevents oil overheating during operation and keeps a constant temperature even during intensive hydraulic use. This solution ensures a more effective and professional exploitation of the tools, said a statement form Jekko. “The new V-Max features all the characteristics of the JF545 standard model, highly appreciated by the sector: endless stabilisation configurations, compact size for maximum accessibility in confined spaces, great lifting capacity (15.5t) combined with outstanding reach (28m), elevated maximum operating

height (30m), triple articulated boom (when jib is installed), removable counterweight, and precise and smooth operation for the most delicate tasks. The use of all the options available for the JF545 is still possible: the work platform and the man basket, the vacuum manipulator for glazed panes and the winch, among many others,” said Jekko. The company statement added that the operator of a JF545 V-Max can choose from a wide range of applications. The standard model already adapts to various operational environments but the V-Max version allows for even more varied applications: from its traditional use in constructions, industry, logistics and handling in confined spaces to more innovative uses with the grapple saw, such as in green areas maintenance. Alberto Franceschini, Jekko export manager, said: “The JF545 V-Max has a huge potential and we believe it will be a very catchy solution for both our established customers and new buyers. We’re already receiving many requests. While developing this version, we’ve been inspired by the concept of a multi-tool machine, extremely versatile, professional and suitable to be used with many different tools and still being user-friendly.” SPECIFICATIONS

REGULAR MAINTENANCE A well-maintained dozer is an efficient dozer, enabling operators to do quality work. Regular maintenance reduces downtime, idle personnel, delays on job progress and repair costs, while increasing safety. Pay close attention to the big three of tracked-equipment maintenance: clean, oil, adjust tension. Also, regular inspection, oil and filter changes, hydraulic check-ups and parts replacements all contribute to better machine upkeep.

INSPECT THE UNDERBELLY Set up a routine for checking the undercarriage and tracks after each use or at least once daily. Ideally inspect the machine at the end of the work-day so debris, sand and mud in the track and undercarriage don’t have a chance to harden overnight. Check and service all the entire undercarriage and track, including bearings, bolts, chains, drive motor, gears, Idlers and rollers, nuts, screws, oil lines, pins, rock guards, shoes, sprockets, tension, water lines and wheels.

CLEAN UNDERCARRIAGE AND TRACKS Daily inspections and keeping the undercarriage clean go together. A shovel, stiff brush or rod helps remove the large chunks of materials such as hardened mud, concrete, rocks, dirt, minerals, wood and other debris. A power washer is another tool that clears dirt and build-up from all the cracks and crevices on the underside of a machine. Chunks of stuff lodged in the track or undercarriage affect performance, cause excess wear and tear and inflict damage.

OPTIMUM OPERATION How equipment is operated makes a difference to undercarriage life. Muddy, rocky, sandy and other environments each have their challenges, from dust and heat to large objects and packed debris in the track. Minimise motions in reverse or high speeds. Avoid excessive or repeated operation on one side. Instead, alternate movements evenly between the sides. On a slope, position the dozer straight up and down rather than sideways. Use digging techniques that do not spin the tracks.

TUNE THE TENSION The tension of the track is another key to a healthy undercarriage and must be neither too tight nor too loose. Technically, the tension should be set to the factory specifications in the manual, but a slightly looser tension is sometimes used for soft ground. Tension too tight can blow out bushings, but too slack will cause slippage or even track detachment. Proper adjustment of the tension also puts the equipment at maximum capacity and operating power.

GREASING AND OILING A well-oiled undercarriage works in favour of cleanliness by pushing dirt out. Oil within the bushings literally enables smoother operation and makes less room for debris to enter the system. The machine manual or a professional technician can help find the grease points on your particular machines for recommended daily lubrication. Grease fittings accept lubrication more easily after use when equipment is warm than before use when it’s cold.

KEEP TRACK Good maintenance records can not only help ensure quality operation, they can also help predict when the track and other components might be due for replacement. Tracking takes a bit of record-keeping but can pay off in the data it yields about the life of undercarriage parts and how the various track treads perform.

MOVERS & PUSHERS

FLATTENING THE REGION’S DUNES AND MOVING TONS OF SAND BEFORE ANY PROJECT CAN START, THE DOZER HAS ALWAYS BEEN VITAL TO THE MIDDLE EAST. NOW WITH LEADING PLAYERS AND NEWER ENTRANTS MAKING A PUSH FOR CUSTOMERS, CMME CHECKS OUT WHAT THE MARKET OFFERS

t is said that well begun is half done. For the many new construction and infrastructure projects that come up ever so frequently in the Middle East, this beginning usually comprises ground preparation, which is the moving of hundreds of tons of sand, soil and rocks to make the bed on which a highway, a tower or a megamall can come up. And to do this, the first machines that land up on a job-site is the bulldozer. The dozer is also among the best known of all construction machinery to the general public. Not everyone can identify – or has indeed even heard of – a motor grader, an articulated hauler, a scraper or a tracked loader. But mention the word bulldozer, and a picture forms – of a heavy, powerful lump-of-metal machine, a behemoth that rolls inexorably over all obstacles on its steel tracks and flatten those obstacles with its iron-fisted blade. Just as a dozer is easily identifiable, its major manufacturers are too. Among them are leading names in the construction machinery industry, such as Komatsu, a long time exponent of the bulldozer and among the market leaders in the world and also the Middle East. Describing the uses that Komatsu dozers – and dozers in general - are put to, Jehad Jayyousi, assistant manager, Marketing, at Komatsu Middle East FZE, says: “The most common work of the bulldozer is cutting and carrying and levelling, which utilises its weight to compact and level the soil or ground surface. Other functions include ripping when equipped with the appropriate equipment for rear work, towing and skidding or even carrying logs in forestry applications. “The bulldozer is among the most economical ways to move material for a short distance, especially on the rough terrain of a job-site. The tracks give the

bulldozer excellent travelability on tough terrain as well as decreasing the ground pressure by distributing machine weight over a larger area, which enables it to work in muddy or sandy ground conditions.” It is especially this ability to work on sand that makes the dozer so important in a region such as the GCC, and Jayyousi adds: “Many projects in our region use Komatsu bulldozers. Due to their ability of working well on sand, they’re the most popular machines for moving large quantities of sand in the desert.” While Komatsu has a wide model range for dozers globally, there are six important models offered in the Middle East. The first two, the D65 and D85, are 20t and 30t machines respectively and aimed at the utility segment user. Best suited for construction are the D155 and D275 machines, which fall in the 40t and 50t operating weight categories, while the larger 70t and 110t machines, the D375 and D475 are suitable for mining applications. “The D155A-6R and D275A-5R variants are our most important and largest selling dozer models in the region, depending on the market. If we look at the UAE, it is the D155A-6R that sells the most. However, in KSA or Egypt, the D275A-5R is more popular,” Jayyousi adds. Explains how Komatsu dozers have several innovative features that have helped the Japanese giant to carve its reputation in the market Yuki Sugiya, product marketing manager, says: “Komatsu bulldozers feature the low-drive system. A key feature of lowdrive is that the machine’s centre of gravity becomes low. This improves the machine’s stability and the dozing and ripping performance. Another feature on Komatsu dozers is automatic control of machine speed to prevent excess shift slip. The newly designed ECMV (Electronic Control Modulation Valve) automatically

29 The D155A-6R is among Komatsu’s best selling dozer models in the region along with the D275A-5R. The former is espeically popular in the UAE while the latter is sought after in Saudi and Egypt.

“Many projects in our region use Komatsu bulldozers. Due to their ability to work well on sand, they’re the most popular machines for moving large quantities of sand in the desert. The D155A-6R and D275A-5R variants are our most important and largest selling dozer models in the region”

adjusts each clutch engagement depending on travel conditions, providing smooth, shockless clutch engagement, improved component life and ride comfort for the operator.” Along with this, Komatsu also offers Intelligent Machine Control on its dozers – the manufacturer’s technology or telematics package that improve job-site efficiency and productivity. Though this feature is yet to arrive in the GCC market, it holds enormous potential for when it does come it. Explaining the concept, Sugiya says: “With every job, Komatsu intelligent dozing saves customers time and money. The automatic control mode boosts productivity in every stage of the process, whether moving thousands of cubic metres of material or for fine grading. Also, with Intelligent Machine Control, there’s no need for staff on ground to check actual surface levels. By reducing the number of workers in the area around the machine, jobsite safety is drastically improved.” Behind everything that Komatsu does is a Japanese philosophy of excellence – Kaizen – that guides it. This is a process of continuous improvement and Jayyousi says it’s part of the Komatsu DNA. “It doesn’t stop even after introducing a new product. Our new Product Introductions are based upon the voice ofcustomer and voice of the distributor. So Kaizen and continuously listening to our partners don’t stop,” he explains. “Another guiding principle for Komatsu is ‘Monozukuri’ (manufacturing competitiveness). Komatsu’s commitment

“Case dozers offer just the ideal size and performance package, with fuel economy and productivity, and minimal wastage in terms of power”

The Cat D8T is Caterpillar’s most important dozer for the region, offering 18% better dozing efficiency for more productivity and up to 10% fuel savings to move more material with every litre of fuel.

to quality and reliability is encapsulated within this fundamental principle. With this in mind, we are dedicated to maintaining a portfolio of first-class products - both machines and technologies − that builds on customer satisfaction. Our basic managerial policies have a strong focus on customer-centricity, creating a manufacturing ecosystem that places customer satisfaction at the forefront of its priorities. We maintain the standards of quality that have become an integral part of our organisational culture through

a continuous process of assessment and refinement that takes place across all areas of our production process. “While we haven’t introduced a completely new bulldozer since 2019, we have constantly refined and improved many features in our current line-up. Our product planning, product marketing and design teams are already working on the next big bulldozer development tailored for our region.” Sugiya says. While that is still some time in the future, a more pertinent question to ask about the present and the recent past is how Komatsu is tackling the disruptions caused by Covid-19. Giving details on the company’s global efforts, Jayyousi says: “The Komatsu Group is combating the pandemic based on government policies of the countries we operate in, with the health and safety of our customers, business partners, community members, employees and their families as our top priority. “Recognising we are positioned as an essential business that supports social infrastructure, and the obligation this represents to customers that are continuing their operations, we are committed to ensuring an ongoing supply of products, parts, services and solutions while taking precautions against the spread of Covid-19. “The global Covid-19 pandemic is impacting our industry in a variety of ways. It has changed our customer job-sites, workstyles and how we engage with stakeholders. With regard to customer job-sites, there is a need to take steps to avoid crowded and confined spaces and close interactions. In terms of equipment, we can therefore expect rising demand for

31 remote, automated and unmanned operation. “Moving on to workstyles, we had more than 90% of employees at our Japan headquarters and over 50% of employees at indirect factory divisions telecommute during the period of emergency and lockdowns. Going forward, we will introduce a full-fledged telecommuting system to streamline and revise work processes with the aim of realising highly productive workstyles to facilitate operations during and after the pandemic. “Engagement with stakeholders is important to us. However, the ways of engaging are clearly changing. We are working to achieve high levels of quality in our communication with stakeholders, even as we maintain safe physical distances.” Two of the biggest aspects of Komatsu dealing with the pandemic are uninterrupted customer support and changes in the way work is done, leading to a change in how machines are used. For the customer service aspect, Komatsu has a dealer network that strictly adhere to its philosophies and aims and objectives. “Our distributors, who we think of as partners, are on the frontline in providing customers with a variety of services before and after the sale. Services start with machine selection recommendation, fleet optimisation, application study, financing and training. Then maintenance and spare parts. Our dozers are subjected to heavy use, and putting this in mind, the design of our machines ensure ease and economy of service.” When it comes to changing demand and the emerging importance of remote operations during and after the pandemic, Komatsu is prepared as it has already been at the forefront of such technology, with which it has created a splash worldwide, though these are still not available in the GCC. Describing the remote-control technology in Komatsu dozers, Jayyousi says: “Our remote controlled (RC) dozers are ideal for applications where customers want to remove the operator from the machine and still maintain high productivity and efficiency. For many operators, the ability to feel machine response to blade load is an important factor in effective dozing. This is naturally difficult when the operator is separated from the machine. Our RC dozers are unique among radio control dozers by combining Intelligent Machine Control systems with RC technology. Thus, the dozer has the ability to sense and control blade load, optimise the start of the cut and minimise track slip. “Currently RC dozers are needed in challenging conditions like very steep slopes, unstable grounds or near hazards. These conditions are not commonly found in our

region. However, the technology keeps evolving. We were pioneers in introducing it and we continue to be pioneers in developing it.” At Case Construction Equipment, the bulldozer forms part of a complete earthmoving line-up. Giving details on Case dozers, Zane Barnard, product specialist, Case Middle East and Africa, says: “Our dozers are small to middle-size. All three dozer models we offer in the region – the 1150L, 1650L and 2050M - are equipped with what we call a PAT

Komatsu dozers offer technological aids for better work and productivity, inlcluding a remote control - or RC - option on some models for situations that may be hazardous for operators.

(Pitch, Angle, Tilt) blade as standard and can also come with a Semi-U type blade.” Barnard explains that they do the land preparation and bulk material moving where needed and also make light work of base material spreading. He points out that the Semi U production blade is ideal for moving large amounts of material, while the PAT blade is a little different as it can swivel left and right, tilt forwards and backwards and go up and down as the dozer pushes the dirt and that enables it to do contouring while moving materials. “The advantage of this is that when using it in applications such as roadmaking, when you’re coming in on a turn while setting up a roadbed, the dozer will pick up that material and spread it for you and get it into pretty much the right position for the next step of the process with a motor grader. Describing the process of Case dozers being used on projects such as road and highway infrastructure works, he says: “Normally, before the process kicks off, excavators and

wheeled loaders are brought in along with the dozers to either remove or add and spread material where needed. On the dozer side this is where our 2050M XLT comes into play, moving material with the aid of a Semi-U production blade. The next step is contouring and landscaping the soon-to-be roadway. All three dozers we offer are useful in this process, each fitted with a PAT blade, making grading, contouring and landscaping quick and easy. And a small dozer, such as we have in our Case line-up, is even more useful for this purpose as it is more manoeuvrable and speedier.” Case dozers are packed with essential features for the region and all are hydrostatic, Barnard says, which means they put more power to the ground and deliver better traction and movability. Another important feature is Case’s V-shaped cooling system that increases surface area and improves cooling efficacy. Case dozers are also fitted with extra-long tracked undercarriages for greater floatation in demanding conditions, he adds. “Case dozers offer just the ideal size and performance package for road building, with fuel economy and productivity, and minimal

wastage in terms of power, offering a complete solution in almost any application. Meanwhile, Caterpillar is a dominant force in the Middle East’s dozer segment. While the company has launched or updated several dozer models in the last 18 months – such as taking its small D1, D2 and D3 dozers to the Next Generation; launching a fully-mechanical version of its D6 for added simplicity; and also launching the new D9 GC in the big dozer class – one of the most important dozers for Cat in the region happens to be the D8T track-

type tractor bulldozer, according to Mohamed Abdulrahman Al-Bahar, the Cat dealer in the GCC countries excluding Saudi Arabia. Samer Ismail, earthmoving and excavation product manager at Al-Bahar, says: “The Cat D8T Track-Type Tractor offers high horsepower, better dozing efficiency and fuel savings. The machine comes with updated cooling and a new powertrain, powered by a proven Cat C15 ACERT engine, and delivers up to 20% better ambient capability. A choice of Cat Connect GRADE technology options help you get more work done in less time.” The key numbers for the new D8T are up to 18% better dozing efficiency for more productivity and up to 10% fuel savings to move more material with every litre of fuel. “Whether you work in desert heat or arctic cold, the D8T takes on the toughest conditions. The largest Semi-Universal blade in the size class helps you move more material with every pass – up to 13% more. To handle the desert heat, a purpose-built Desert Arrangement includes added cooling performance and more protection for working in extremely sandy or abrasive conditions. This makes the new D8T ideally suited for

LIEBHERR PR 776 MINING DOZER

100 UNITS OF SUCCESS The Liebherr factory in Telfs, Austria, recently celebrated the commissioning of 100 PR 776 Mining Dozers, which Liebherr says is the world’s largest of their kind. Since the market launch of the model in 2016, the PR 776 has achieved many successes and exceeded the expectations of Liebherr customers worldwide, the manufacturer adds. A mining dozer in the 70t-class and featuring a hydrostatic travel drive, the PR 776 offers high efficiency for customers with its powerful Liebherr diesel engine in

combination with a standard ECO mode. This allows operators to choose between high performance and maximum efficiency at any time. With 100 dozers in operation, a total of 760,000 operating hours and an average of 38 litres of fuel burnt per hour, the PR 776 has also set the bar high regarding efficient dozing in the mining industry, Liebherr adds. Led by the first ever commissioned Liebherr PR 776 in 2016, which has nearly 30,000 operating hours today, the biggest fleet of the model is running in

Russia. Followed by the African, Australian and North American markets, the Liebherr mining dozers are mainly supporting the extraction of a broad range of commodities. To withstand the ambient temperatures in the different regions, ranging between -49°C and +46°C, the PR 776 dozer can be optionally equipped with an arctic package. In addition, a special high-altitude package has been developed by the Liebherr R&D department to handle the oxygen saturation of only 50% in a copper mine in Maizhokunggar, Tibet, situated

nearly 5,500m above sea level. Liebherr says multiple customer success stories and competitive comparisons have shown that its hydrostatic dozer can not only keep up with other 70t dozers in terms of pushing performance, it even outperforms them with regard to tonnes per litre pushed. Inside the cabin operators have the convenience and simplicity of a single joystick while safety is enhanced via 360-degree blade and ripper visibility, provided by large panoramic windows integrated with ROPS/FOPS in the cab structure.

“The Dressta-Sintra combination is making customers interested in getting something different and new without compromising on quality, efficiency and after-sales back-up” the working conditions we have here in the Middle East.” Ismail explains. Coming to the technology of the machine, he adds that the CAT LINK technology takes the complexity out of job-sites and “serves it up to you in customisable formats”. “Product Link collects machine data that can be viewed online through web and mobile applications. You can access the information anytime and anywhere with VisionLink and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve security on your job-site,” Ismail says. The D8T meets the demands of desert applications with several special features ideally suited to supporting machine performance and service life in extremely sandy or abrasive conditions. Explaining these, Ismail adds: “There’s a Pre-cleaner Turbine air intake system that prevents nearly all of the heavier-than-air particles from entering the system, which results in longer air filter life, more efficient engine performance and decreased maintenance expenses. The engine enclosure doors are solid at the bottom to help reduce the amount of sand carried into the engine compartment for improved cooling and reduced cleanout time.” Another established global dozer brand that has a firm foothold in the GCC region is Poland’s Dressta, which his now under the LiuGong umbrella. Saide Hamoucha, founder and CEO of Sintra Middle East, Dressta’s representative in the region, says the company’s line-up of machines available here are the TD-10, TD14, TD15, TD20 and TD25, while two models offerings pipelayer functions are the SB60 and SB85. “Dressta offers a full line of crawler dozers in the 101-536hp range and pipe layers with a

maximum lifting capacity of 100t. Dressta can configure its products for performance in a variety of applications. Our focus in the Middle East is on our TD-15M and TD25M models, which are our leading products.” Of these, the TD25M is the best-seller. Hamoucha says it fits most applications in the region and also offers advantages such as a bigger blade when compared to the Cat D8 and Komatsu D-155, its direct competitors. Its higher drawbar pull of about 20% provides 800kN, whereas competitor machines offer

Poland’s Dressta has a history of making robust and innovative dozers and is represented in the region by Sintra Middle East, whose service has already netted many large customers.

about 650kN. The TD25 ripper is also heavier than the competition at 5.3t, which when coupled with the models higher pushing force results in 15%-20% higher ripping productivity. The TD25M also has a fuel tank of 800 litres, the largest in its class. “Our latest introduction is the TD-25M Series 1, the successor to our legendary TD25M Extra, in which visibility and safety have been greatly improved with 30% more glass in the new pressurized cab and the inclusion of rear cameras. The highlight for 2021 will be the TD-15M Series 2 with new advanced electro-hydraulic steering which provides pinpoint accuracy and new outlook with a fresh design. Also, Dressta future release is going to be the TD16N - a revolutionary, new dozer, which won the Red Dot design at ConExpo 2020,” Hamoucha reveals. “Among the Dressta’s special features is its two-speed steering drive, which provides the highest drawbar pull in each dozer class, providing full power at all times, including in turns, allowing for the use of bigger blades. Dressta’s drivetrains are service and maintenance friendly, and diagnosis and problem-solving can be done on every desert job-site with a set of pressure gauges only. Dressta’s drivetrain is also the only one to deliver six speeds forwards and reverse, that makes the dozer more aggressive in pushing. The Wet Clutch Steering Drive is also more robust than hydrostatic drive systems. A ‘Dirty Fuel Special Filtration Kit’ deals with any issue of low-quality fuel, while external sight gauges for engine coolant and hydraulic oil makes for easier daily maintenance.” If that’s not enough then there is comprehensive back-up in the form of Sintra Middle East’s experience and expertise, Hamoucha adds. “Dressta is also supporting the market here with more than 80% spare parts availability shipped directly from Dressta Parts Centre to end users in less than a week. The DresstaSintra combination is making large and key customers interested in getting something different and new without compromising on quality, efficiency and after-sales back-up. No wonder then that we can report several happy customers including governments, such as a Saudi government department which acquired 45 units recently, or private contractors such as Abu Dhabi’s Applied Technology, who took eight units. We also have several Dressta units working in the Etihad Railway project and with ADNOC in the oil & gas sector in Abu Dhabi.” With clearing and pushing material a constant necessity in the construction sector, the regional dozer segment can be expected to keep developing apace, with the battle having been joined by several global players.

ELECTRIC PULSE

HAULOTTE’S NEW HS15 E AND HS18 E PULSEO ALL-TERRAIN ELECTRIC SCISSOR LIFTS OFFER PERFORMANCE EQUIVALENT TO DIESEL MACHINES, WITH HIGH REACH AND PLATFORM CAPACITIES, THE ABILITY TO TACKLE VARIOUS TERRAIN, AND CONVENIENT CHARGING AND BATTERY MANAGEMENT

aulotte has launched two new all-terrain scissor lifts that are electrically driven but offer the same level of performance as diesel machines, with working heights of up to 13m, load capacity of 750kg and the ability to be deployed on slopes with up to five-degree gradients. The French powered access heavyweight said that the launch of the new HS15 E and HS18 E models are part of its “blue strategy”, and integrate unique features, widening the range of possibilities, both in terms of applications and working independence.

“Their fully electric architecture offers the same outstanding drive performance of an internal combustion diesel machine. This new generation of scissor lifts reinforces the direction taken by the Group in recent years towards versatility and environmentally friendly alternative energies,” said a spokesperson from Haulotte. The PULSEO scissors are designed to maximise battery life with the 48V battery pack delivering the range necessary for a full day of work. Three charging solutions adapt to the on-site infrastructure, with the primary charger recharging the batteries at the end of the shift from any standard 110-230V single phase electrical network, an optional three-phase accelerated charger ensuring an 80% charge in only three hours and

a removable and interchangeable range extender to rapidly recharge the batteries while the machine remains fully operational. One range extender can be used on different HS15 E or HS18 E. According to Haulotte, the HS15 E and HS18 E scissor lifts are able to work in varied terrain and can climb slopes up to 45%. The have oscillating axles that match the position of the front wheels to the uneven terrain to maintain optimal ground traction. The four-wheel drive axles deliver maximum torque and ensure excellent power distribution. In low grip situations, the manual differential wheel lock provides extra traction, getting the machine in and out of challenging terrain. They can be deployed on slopes up to 5° with outriggers for safe elevation on uneven ground. High ground clearance protects

35 machine components in all terrain conditions. The HS15 E and HS18 E scissors feature a high load capacity to meet demanding applications such as cladding, insulation, maintenance work, etc., and can lift up to 750kg of load and up to four persons. The work platform is a large one, with a length of 7.40m when both extensions are deployed. Full working height for is up to 13m for the HS18 E. Proportional commands ensure precise movements and smooth operation on the way up to the work area, while ergonomic controls guarantee comfortable driving. The new PULSEO scissors incorporate the Haulotte Activ’Lighting System with 10 LED spotlights providing illumination of the basket, controls, and the manoeuvring area around the machine for safe

loading/unloading operations in low visibility. New on scissors, the Haulotte Activ’Shield Bar system protects the driver from entrapment situations. The machine stops automatically as the operator is pushed towards the bar. According to Haulotte, more and more cities and companies are taking steps to reduce their environmental footprint and “with the 100% electric design, the HS15 E and HS18 E scissors operate with no harmful emissions”. “They offer a clean alternative suited to any situation, such as Low Emission Zones (LEZ), or green construction sites. Available with non-marking tyres, they can also be used indoors on sensitive surfaces without leaving a trace. The latest PULSEO machines operate in silence (acoustic profile <60

dB in electric mode); they are perfect for work in low-noise areas or public places without bothering people nearby,” said Haulotte. TECH SPECS
