< PreviousT he European Rental Association, the voice of the European equipment rental industry, has launched the ERA Equipment CO2 Calculator, an independent and free-to-use online tool to enable equip- ment stakeholders to make more sustainable choices when using construction equipment. The ERA Equipment CO2 Calculator, which will complement the ERA TCO Cal- culator, is primarily targeted at contractors, rental companies, distributors, OEMs, public authorities and other equipment users. The calculations were developed by the independent research consultancy CE Delft, who fi rst developed the tool for the ‘Carbon Footprint of Construction Equipment’ study released in 2019, and the online tool was built by Alias, a digital services provider. The Calculator determines the carbon footprint of construction equipment over its entire lifecycle and is applicable to all types of equipment, from mini excavators and wheel loaders to generators, boom lifts and access platforms. The results provide an estimate of the car- bon footprint per hour of use, allowing con- struction equipment users to, for example, compare diff erent use scenarios, investigate which part of the lifecycle contributes most to the carbon footprint and evaluate the ef- fects of alternative fuel choices. The Calculator can be used to evaluate a single ownership period of one piece of equipment and, furthermore, to determine the climate impact of entire fl eets of equip- ment or the total carbon footprint of all ma- chines on a given construction site. Michel Petitjean, secretary general, ERA, said: “The ERA Equipment CO2 Calculator is the fi rst of its kind and a much-needed tool to help bring down emissions in the construction sector. By enabling equipment users to see the carbon footprint of their machinery for every hour of use, they can make the most environmentally sustainable choices when deciding whether to rent, lease or purchase equipment, evaluate areas for improvement and, ultimately, reduce their carbon footprint.” The tool also allows users to directly com- pare two separate scenarios for using con- struction equipment. “By providing direct comparisons of dis- tinct scenarios, it is much easier for equip- ment stakeholders to evaluate diff erent op- tions when using construction equipment. This means that they can make the most HOW TO ESTIMATE THE CARBON FOOTPRINT OF CONSTRUCTION EQUIPMENT OVER ITS ENTIRE LIFE CYCLE SUSTAINABILITY 40 PLANT / MACHINERY / VEHICLESAPRIL 2021www.plantmachineryvehicles.comsustainable choices and mini- mise their impact on the envi- ronment,” said Michel. HOW THE CALCULATOR WORKS The Calculator has six easy steps, requiring basic informa- tion about the characteristics and use of a piece of equip- ment – equipment production, transportation, lifetime and utilisation, energy consump- tion, maintenance and end-of- life – and the users are guided through the process step-by- step. The user information is com- bined with background data to estimate the carbon footprint of the equipment over its life- cycle, presenting a total carbon footprint per hour of use and a breakdown of the carbon foot- print per parameter. The Calculator is easy to use, with a simple registration process for users to save their calculations for later use. Al- ternatively, users can do single calculations without the need to register. The Calculator can also be embedded on external websites. The values that need to be inserted into the tool in order to perform a calculation are: • Equipment weight (in kg) • Carbon footprint result from an LCA ( in kg CO2-equivalent) – optional for construction equipment • Load capacity of the truck/van carried the equipment to a jobsite (in tonne) • Truck load capacity factor (as a percentage) • One-way distance over which the equip- ment is transported to a jobsite (in km) • The average number of jobs per year • Total expected operating hours in total life- time of the equipment; • Ownership period (in years); • Total expected operating hours used dur- ing your company’s ownership • Average energy consumption per hour (fuel or electricity) • Share of biofuels in for fuel or country of use for electricity Motor oil consumption (in litres per year) • Degree by which the equipment is recycled at the end of life. The Calculator contains the option to esti- mate the carbon footprint for the production and end-of-life stages of construction equip- ment based on the equipment weight, but this estimate does not apply to hand tools or other types of equipment (modular space units etc). This weight-based estimate was developed based on information for larger equipment (1,500 to 15,000 kg). Because hand tools are lighter and com- posed of diff erent materials, the weight- based estimate can lead to incorrect re- sults. For other types of equipment outside of larger construction equipment (such as hand tools, modular space units, forklifts, pumps etc.), the calculator can only be used for provided that the user has an LCA from the manufacturer of the specifi c product is available. RENTING EQUIPMENT REDUCES CARBON EMISSIONS Two years ago, three specialised, indepen- dent research companies – Climate Neutral Group, CE Delft and SGS Search – researched and calculated the CO2 emissions during the full life-cycle of equipment representative of the portfolio of ERA members. The main objective of the project was to discover the environmental impact of con- struction equipment through independent analysis. Ten pieces of equipment, from several manufacturers were selected to be analysed for the research to represent a wide variety of popular equipment categories, including earthmoving, material handling, access, power and tool. The research con- sultants determined the carbon footprint of the use of construction equipment, based on various parameters. The parameters having the most infl uence on the carbon footprint of equipment are: • Intensity of use – maximising the utilisa- tion rate could reduce the amount of equip- ment required • Using the right equipment for the job • Transportation – shorter distance and high load factors • Maintenance – allowing extended lifetime The research concluded that effi cient use lowers the total carbon footprint of the piec- es of equipment and that the rental business model stimulates effi cient use. Depending on specifi c user practice, ERA estimates that this can lead to signifi cant reductions, in the range of 30% and sometimes over 50%. SUSTAINABILITY 41 PLANT / MACHINERY / VEHICLESAPRIL 2021www.plantmachineryvehicles.comA s a manufacturer of diesel engines for over 109 years, Yanmar understands the intricacies of engine technology and how to adapt it for various applications. Normally, new engines from Yanmar are tested in the factory for 50 hours before they’re delivered to customers. This helps detect even the smallest manufacturing defects in order to ensure their durability. As a result, Yanmar engines are the most reliable in their categories; it’s common to see Yanmar engines running smoothly for over 40 years on boats as their ownership is passed down from one generation to another. In the UAE, Al-Futtaim Auto & Machinery Co. (FAMCO) has been the exclusive authorized partner of Yanmar marine engines for over 50 years, supplying diesel engines for commercial and pleasure vessels. Yanmar's high-performance engines are designed for maximum life and are tested under extreme conditions. Ramez Hamdan, managing director- industrial equipment (Al-Futtaim Motors, FAMCO, HINO and Toyota Material Handling), says: "At FAMCO, we off er an integrated service that includes design of propulsion and power systems. What sets Yanmar marine engines apart from other brands is that they are purpose-built for marine applications and not ‘marinised’, which means engines developed for other vehicles such as trucks are modifi ed for marine applications." Samer Al Junaidi, divisional manager- CE, marine, power and industrial products, FAMCO, adds: “We off er turnkey solutions for propulsion systems including the engine, gearbox, steering system and propellers. In eff ect, we convert an empty hull into a fi nished vehicle that is ready to be powered on. For small boats up to 18m, we install the systems 42 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comAPRIL 2021 POWER EQUIPMENT THE MARINE ENGINE SPECIALISTS Yanmar’s purpose-built engines for marine applications and FAMCO’s integrated services and support ensures the uptime of pleasure boats and commercial vessels at our Dubai workshop; for larger vessels, we install them at shipyards. Yanmar engines and spare parts can be ordered online. The lead time for engines ranges from 4 to 6 months. However, we maintain our own stock to cater to regular on-going projects.” Commercial vessels, off shore vessels, cargo vessels and fi shing boats comprise FAMCO’s largest markets for marine engines, followed by pleasure boats. FAMCO facilitates procurement, maintenance and servicing of engines through its main offi ce, workshop and warehouse in Dubai and additional warehouses for spare parts in Abu Dhabi and Ras Al Khaimah. Ahmed Gamal Morsy, national sales and aftersales manager, marine solutions, power and industrial product division, FAMCO, points out the common causes of marine engine failure: they include overloading, fuel shortage/contamination, low oil pressure, cooling system failure, misalignment between the engine, gearbox and propulsion system which causes vibrations resulting in the breakage of engine components, and poor design of the exhaust systems, among several other factors. Such incidents can be avoided, especially at sea, with the right selection of engines and design of propulsion systems. “On average, engines run for about 14,000 to 16,000 hours before an overhaul. Commercial vessels have their own engineering teams on board to handle routine maintenance. Pleasure boat owners tend to use our services especially when the engine is under warranty and even beyond that period because they prefer to deal with an authorised and trusted supplier like FAMCO. Our experts provide guidance on when to rebuild, repower or replace and engine. Sometimes, it’s worthwhile to replace a damaged engine if the repair cost is close to the price of a new engine. However, if the customer cannot aff ord a long downtime, then the better option would be to overhaul the engine by replacing parts instead of installing a new engine,” says Ahmed. “With predictive maintenance, for example, we can plan for an overhaul after 14,000 hours with availability of parts. With corrective maintenance, we monitor the engine and take corrective action only after we detect a fault or to compensate for wear and tear. Failure maintenance comes into play after failure of the engine. Of course, we recommend predictive and routine maintenance to maximise the lifespan of the engine,” he adds. In addition to performance and build quality, low fuel consumption and low emissions are among the defi ning characteristics of Yanmar engines. In general, when NOx emissions are reduced, the fuel consumption and smoke generation increase. As a solution to this, Yanmar developed its patented ‘ASSIGN’ Combustion System (Available Space Scattering Injection Geometric Nexus), which improves the fuel consumption and smoke generation while reducing NOx emissions. Yanmar marine diesel engines also comply with IMO Tier II emission requirements for the Middle East. “Being a premium brand, Yanmar still off ers a competitive pricing structure. Yanmar engines are primarily mechanical engines which allow any technician to maintain or repair the engines, compared to electronic engines that require a dedicated staff or authorised technicians. This is crucial if servicing or repair is required at sea. We also provide mechanical engines with electronic controls for a more user-friendly operation,” says Ahmed.

Kaeser’s Mobilair range of portable compressors provide fl ow rates ranging from 1.6m3/min for small compressors to 45.8 m3/ min for large, oil-free models. According to Carl Briden, managing director, Kaeser Kompressoren FZE, all Kaeser portable compressors can handle whatever application they are used for, without any modifi cation required. “The Kaeser portable screw compressor is robust and well designed to operate in extreme conditions found across the globe. As Kaeser portable screw compressors are based on a single stage screw design, there is of course a limit to the maximum pressure achievable; however, in this market sector, high pressures are required only in limited applications,” says Carl. Considering the versatility of the Mobilair range, there are several factors to be considered while choosing compressors for construction and oil and gas project, Carl points out. “Construction compressors are diesel driven portable machines designed for outdoor use and deliver compressed air to a standard suitable for rugged air tools and other applications where extremely high compressed air quality is not essential. As such, they are not suited to oil and gas applications. Kaeser off ers custom-made compressor packages for oil and gas applications, which include electric driven compressors and downstream air treatment, all of which are generally mounted on base frames with inter-connecting pipework and control modules suited to communicate with clients' central management systems,” he says. Carl elaborates on Kaeser’s product development strategy, aimed at helping customers reduce operating costs. “Our industrial range of machines together with correctly designed management systems already meet the demands of ‘I 4.0’. The energy saving Kaeser screw compressor further reduces the electricity consumed by factories, which in turn helps reduce their respective carbon footprint. For construction sectors in developed markets that have high emission standards, our portable compressors comply with all standards, entirely. In addition, via our smart control system, portable compressors can be remotely monitored wherever they may operate,” says Carl. “For the industrial market, we help reduce operating costs by listening carefully to customer needs fi rst and only then make a precise design best suited to their requirements. This approach ensures machines are sized correctly and are managed and perform at their most effi cient point at any time during a production cycle. For the construction sector, we ensure low operating costs by design - allowing easy access to all components to reduce maintenance down times and longer machine life,” he adds. KAESER’S PORTABLE COMPRESSORS ARE DESIGNED TO OPERATE IN ALL CONDITIONS Carl Briden, managing director, Kaeser Kompressoren. 44 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comAPRIL 2021 POWER EQUIPMENTC aterpillar has launched 31 new models of Cat GC diesel generator sets, the company’s new range of value- engineered standby power solutions specifi cally targeted at the global electrical contractor market.

CATERPILLAR LAUNCHES 31 NEW GC DIESEL GENERATOR SETS FOR THE GLOBAL ELECTRICAL CONTRACTOR MARKET 45 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comAPRIL 2021 POWER EQUIPMENTW hen Jasmine Water and Beverages Factory, a large water and beverage factory based 120km west from Riyadh city, needed a reliable and uninterrupted power supply for its 24/7 operations, they turned to Atlas Copco’s partner GCC Olayan for a solution. Jasmine Water and Beverages Factory's plant is situated in a remote location in the desert, without access to the power grid. Therefore, the company faced frequent power failures, making the continuous production line diffi cult. That is why Jasmine Water and Beverages required a reliable generator. To overcome the challenge, GCC Olayan, the offi cial distributor of Atlas Copco’s Power and Flow division in Saudi Arabia recommended four TwinPower generators. The TwinPower from Atlas Copco is a containerised portable generator that delivers versatility, fuel economy, and twice the amount of on-site power than conventional independent power plants (IPPS). Atlas Copco TwinPower is a 20 ft. ISO containerised unit housing two compact 500 kVA generators powered by compact Scania engines. This confi guration, with an advanced control system, allows the two generators to work independently or in parallel with each other. This makes it ideally suited for applications that have variable power needs, whether due to the time of day or the current usage requirement. Ahmed R. Badawi, regional sales and marketing manager – Power and Light, Atlas Copco, said: “The QAC 1100 TwinPower is perfect for applications that require intensive use because it delivers high performance while maximising fuel effi ciency, cutting associated running costs, and low-cost of ownership, amongst other benefi ts. Also, thanks to its fl exible design of two generators in one platform, it gives our client fl exibility and the QAC 1100 generator works in the harshest conditions, such as a very hot climate in a Saudi desert.” As Jasmine Water and Beverages Factory needed 4,000 kVA to work in synchronisation, Atlas Copco modifi ed the totalization and distribution panel and fuel systems of the TwinPower units. To ensure the best fuel optimisation, Atlas Copco recommends using the power management system (PMS) mode. The TwinPower is equipped with a centralised control and monitoring system that is both easy-to-use and confi gure. This is facilitated by two Qc4003 digital controllers that feature intuitive touchscreens, and a choice of island or PMS modes. Ashraf El-Nahas, factory general manager, Jasmine Water and Beverages Factory, said: “We are very pleased with the Atlas Copco QAC 1100 TwinPower. It provides us with the reliable power supply that our production line needed to run 24/7 without cuts while off ering us the best fuel optimisation for our plant. We highly recommend working with GCC Olayan and Atlas Copco because all the projects have run smoothly and in a timely manner.” Atlas Copco TwinPower is designed for easy service. Large access doors and custom service tools make for eff ortless maintenance and assured uptime. The positioning of the motor and alternator sets on opposite sides enable multiple access points to all the main components. Ibrahim Nazih, Atlas Copco division manager, GCC Olayan commented: “We are delighted Jasmine Water and Beverages Factory trusted us with this project, and we look forward to continuing working with them via our service package.” 46 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comAPRIL 2021 POWER EQUIPMENT ATLAS COPCO TWINPOWER GENERATORS POWER LARGE WATER AND BEVERAGE FACTORY IN SAUDI ARABIA V olvo Penta’s D8 Stage II and IIIA/Tier 3 genset engine has been built with a high power-to-weight ratio, giving it high power density and a compact design for its power class. It has been designed for quick, easy, and economical installation as well as ease of operation and maintenance. The D8 features state-of-the-art, high-tech diesel fuel injection and charging systems with low internal losses. This 8-liter power generation engine has been developed to produce smooth and vibration-free operation with low noise levels. The lower noise emissions have been achieved by choosing more sophisticated fuel injection technology and by adding a top-of-the-line Visco fan clutch. Compared to previous products, noise reductions of up to 2.5% have been measured. To verify performance, reliability, and durability, the D8 was tested to the maximum – at temperatures of -25°C through to 60°C of sweltering heat – in real-world fi eld tests with customers. This extensive testing ensures the engine functions with the required performance and reliability levels in all the applications, climates, and environments. D esigned for off -highway applications in both static and mobile industrial equipment and generators, JCB’s new engines are available in four power nodes spanning from 81kW (108hp) - 129kW (173hp) and boost peak torque outputs from 516Nm to 690Nm. Building on the hugely successful transition to Stage V power in the <56kW range with the 430 engine, the new higher powered 448 models feature the same highly effi cient performance with a simple, fl exible aftertreatment solution and common customer connection points to enable easy integration with a wide range of OEM equipment designs. The engine packages have been engineered to be as small as possible while featuring engine mounted aftertreatment – which comprises a diesel oxidation catalyst with a selective catalytic reduction urea injection system for NOx reduction as standard, to simplify engine integration. Exhaust aftertreatment can also be supplied loose for bespoke installations where height limitations call for an alternative to the engine-mounted arrangement. The development of these Stage V 448 units will enable JCB Power Systems to continue to support new and existing customers in off highway applications across markets with Stage V regulations and then further territories as emissions legislation evolves. The new Stage V range builds upon its predecessor, the 448 JCB engine, proven in OEM installations across Europe, North American and the global market. Effi ciency is the key focus and the new models deliver low fuel consumption, thus lowering CO2 and other exhaust emissions. The versatility of these engines makes them suitable for a wide range of uses, from propulsion of off -highway equipment to the mechanical power behind a variety of stationary equipment. They are ideal for heavy duty environments due to the high power density of the engines, with its robust design withstanding the environmental factors that are seen in these applications – such as dust and vibration. VOLVO PENTA’S D8 GENSET ENGINE DELIVERS HIGH POWER DENSITY, LOW FUEL CONSUMPTION AND LOW NOISE LEVELS JCB POWER SYSTEMS UNVEILS STAGE-V COMPLIANT ENGINES TO POWER OEM EQUIPMENT 48 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comAPRIL 2021 POWER EQUIPMENTC ummins has introduced a dual-dosing urea injection system for the new Scania V8 range, contributing to enhanced emissions control and improved fuel-effi ciency for the Euro VI truck engine rated up to 770 hp (566 kW) output. The dual-dosing system for the upgraded Euro VI Scania V8 is supplied from the Cummins Emission Solutions (CES) facility located in Marktheidenfeld, Germany. The next generation Cummins system is the fi rst to introduce dual-dosing architecture to the truck industry, introducing a diff erent approach to exhaust aftertreatment control that can contribute to reducing nitrogen oxides (NOx) emissions, as well as helping to reduce CO2 levels. The dual-dosing system applies two streams of urea, known as AdBlue or diesel exhaust fl uid (DEF), into the exhaust stream of a selective catalytic reduction (SCR) system to convert emissions into harmless vapour. The system is able to increase the eff ectiveness of NOx conversion during the low levels of heat at engine start-up and low- load running, with an additional benefi t of enabling the engine combustion formula to reduce fuel consumption. This system brings a new approach to resolve the NOx emissions control challenge resulting from low temperatures within the aftertreatment exhaust fl ow. During cold cycle operations, the SCR-DPF aftertreatment becomes far less eff ective in reducing emissions as the reduced heat level adversely impacts the catalytic chemistry. This typically occurs under cold start conditions, low driving speeds, engine idling and with low ambient temperatures, representing a signifi cant obstacle to meet extremely low emissions levels. The dual-dosing design helps to reduce emissions spikes during cold cycle conditions by close-coupling the fi rst doser at the turbocharger outlet. This utilizes higher temperatures present as the exhaust stream exits the engine and enables the injected urea stream to maximize the emissions reduction. The second doser is located at the aftertreatment unit and operates when additional NOx reduction is required. Dual-dosing, when combined with other next generation systems such as turbocharging, fuel injection, electronic management and aftertreatment can enhance the ability of diesel engines to meet more stringent emission goals. The system also brings a further benefi t by enabling the engine combustion formula to reduce fuel consumption, as the need to generate excessive engine heat for the urea stream blending is eliminated. Depending on engine architecture and driving factors, this could improve fuel-effi ciency by 2 to 3 percent. This savings will play a signifi cant contribution in helping trucks to reduce their carbon footprint and more easily meet the upcoming greenhouse gas (GHG) regulations. Now commercially available, the dual- dosing system has a modular design adaptable to a wide range of engine displacements and SCR aftertreatment confi gurations. With both dosers acting as a single, fully synchronized system, this ensures the amount of urea injected (AdBlue or DEF) is equivalent to that of today’s single-dosing systems. The system is designed for both low-fl ow and high-fl ow SCR systems, with the capability of meeting dosing rates up to 16 kg/hr. Robert Cochanski Rodriguez, general manager, Cummins Emission Solutions in Europe, Middle East and Africa, said: “Cummins is a long term supplier of high precision urea dosing systems to Scania, and we were able to leverage our long-standing collaboration to introduce this innovative dual-dosing solution for their upgraded V8 product. It has taken thousands of hours of research and development, but I am delighted to say that the new system meets very demanding cold start conditions and operates robustly against harsh vibrations, achieving this while maintaining peak performance across a wider temperature range than previous systems.” CUMMINS DEVELOPS DUAL-DOSING SYSTEM FOR THE NEW SCANIA V8 49 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comAPRIL 2021 POWER EQUIPMENTNext >
