Yanmar board member Shiori Nagata says the world of construction machinery and powertrains is evolving, with manufacturers and end-users alike driving the transition from traditional combustion engines to battery power.  

However, she says, this new scenario brings with it fresh challenges for original equipment manufacturers (OEMs) and power systems suppliers.

Yanmar will therefore establish itself as the all-in-one systems integrator for smart electrified power solutions tailored to the application-specific needs of individual OEMs.  

In its capacity as a systems integrator, Yanmar will implement system engineering, design and manufacturing of e-powertrains, while providing control development, system evaluation, procurement, manufacturing and quality assurance.

“As Yanmar looks to meet the challenges of the coming century, our transformation will encompass new products with alternative fuel technologies,” says Tomohisa Tao, president Yanmar Power Technology.

“Our aim in this strategy, together with our dealers and OEM partners, is to build stronger relationships and create even greater customer value with new-energy technology. We will work hard to support our OEM partners and customers to achieve their environmental and performance goals.”

Carlo Giudici, Yanmar Europe sales director EMEA, adds that the company will accelerate its e-powertrain strategy in the next few months.

“Furthermore, we are giving ourselves another challenge this year – the Yanmar Green Challenge 2050. It is a declaration and a challenge we impose on ourselves to become a company that achieves zero greenhouse gas emissions and a zero ecological footprint by recycling resources,” Giudici says.

Based on a SANY electric chassis, the iONTRON eMixer is 100% electrically powered, confirms head of product management Markus Frasch. No carbon emissions are released during operation – neither during the journey nor when working on-site.

“The 315-kW e-motor offers great torque and virtually silent operation,” said Frasch. “This means that the eMixer can drive without restrictions – even in places where strict noise regulations apply. This offers a competitive advantage when tendering for construction projects with strict environmental protection stipulations.”  

The 8x4 axle configuration offers up to 34tonnes permissible gross weight. Reliable performance, added Frasch, was top priority during development. Thus, the battery charge of the iONTRON eMixer lasts a whole working day in urban areas – offering about five to six trips and a range of up to 150km.

“This is made possible by the 350kWh battery technology. If more trips are planned, it can simply be opportunity-charged in between trips. The mixer recovers its full power overnight by charging at a DC charging station.”  

While the firm is already producing its eTRAC eCD20-40 electric drives for compact vehicles, and the first pilot projects are underway for the next larger eCD 50-90 series, the newly-developed eCD160 system will offer solutions for electric construction machinery weighing up to 20tonnes.

The components are matched to a system consisting of an electro-mechanical powershift transmission and one e-motor for traction and ePTO each. An electric drive control unit for overall system performance and power management completes the system. With a 650V operating voltage, the system can be scaled up to 120kW continuous power; the ePTO ranges from 30-70kW continuous power.

Based on the established ERGOPOWER powershift technology, the eTRAC system is not intended to replace the conventional driveline technology. Instead, its modular design that allows a large number of drive concepts to be covered and to react even more flexibly to customer requirements in the future.

The newly developed solution can be integrated into battery-electric vehicles as well as vehicles with fuel cells. At the same time, conventional drives with powershift and power split transmissions will remain, even for alternative fuels such as hydrogen, eFuels, or biodiesel.

The K42E is equipped with a 30amp hour cell battery pack that powers two Rexroth electric motors. The first drives the hydraulic pump to move the boom and open the outriggers, while the second drives the pumping unit, in a closed circuit and at maximum capacity of 160m³/hour at 80bar.

The charging process is quick and easy, says the company, with the integrated battery charger compatible with the 220V system. The boom extends up to 42m and consists of five sections, with the last two made from carbon fibre.

“If the job requires higher performance than the batteries can provide, the new Energya pump can be connected directly to an electrical outlet on site,” explains Davide Cipolla, CIFA’s CEO. “The system will then cut out the batteries and power the electric motors directly from the power source. A 40m power cable is included.”  

This, he adds, means that the pump continues to operate with the truck’s diesel engine switched off, thus eliminating emissions and noise. If there is no electrical supply on site, an emergency system allows end-users to connect the K42E to the truck’s power take-offs and use the engine to complete the work, then close the boom and outriggers.

“The aim is to eliminate CO2 and noise emissions throughout the supply chain, from transport to laying of the concrete, by expanding the possibilities of using high-performance vehicles in areas where noise pollution and CO2 emissions are prohibited,” adds Cipolla. “The special feature of the Energya K42E pump is that the battery allows it to always operate in full electric mode.” 

Since January 2021, Komatsu and US-based Proterra have been jointly developing electric medium-sized hydraulic excavators and have been conducting Proof of Concept tests on advanced research machines at customers' construction sites.  

The PC210E is scheduled to be introduced to the Japanese and European markets in financial year 2023.

Komatsu notes that hydraulic excavators are the most versatile type of construction equipment, and the mid-size class is used in a wide range of jobsites and applications, mainly in earth excavation and loading operations, requiring power and durability to withstand heavy-load work.

The PC210E model is said by the manufacturer to optimise the entire body control system by capitalising on Komatsu’s proprietary coordinating technology.  

It specifically integrates Proterra’s lithium-ion battery technology, which has a proven track record for use in heavy-duty and commercial vehicles deployed in various fields globally, combined with Komatsu’s components such as the hydraulic pump, controller, and electric motor for work equipment operation.  

Komatsu has also developed a robust cage structure to provide additional protection onboard the vehicle for its battery packs.  

As a result, the company has achieved digging performance and durability equivalent to those of engine-driven hydraulic excavators. In addition, the high energy levels in the excavator’s Proterra battery system enables operation for up to a claimed eight hours when fully charged.

The excavator’s electric power makes it possible to work comfortably in various work environments without worrying about noise and exhaust emissions and is expected to be used for work in urban areas and night-time construction work. The zero-engine vibration also helps reduce operator fatigue.

As global awareness of climate change accelerates, Komatsu has declared it plans to achieve carbon neutrality by 2050. In collaboration with its partners, the company is developing electric construction equipment to achieve zero exhaust gas emissions and a significant reduction in noise, with the vision of developing safe, highly productive, smart and clean workplaces of the future.

Local emission-free operation is said to be possible thanks to the model’s E-DRIVE diesel-electric drive with the option of external power supply.

Thanks to this external supply, the system can be operated without emissions. This ensures low energy consumption per tonne of end product. The electric drive also means that hydraulic oil is only required for setting and set-up functions. This minimises risk to the environment and further increases the system’s sustainability.

When the Mobirex MR 130(i) PRO is operated via the diesel unit, the performance and load-dependent fan is said to ensure efficient use of fuel and low noise emissions. The formation of dust is also said by Kleemann to be greatly reduced by water spraying at all relevant points, such as the crusher inlet, the discharge belts and the post-screening unit, as well as various belt covers.

The Kleemann PRO-Line system can process up to 600 t/h of material. The high output is made possible by the crushing unit with a heavy rotor and a 250kW drive in conjunction with efficient pre-screening. The Continuous Feed Systems’ (CFS) continuous feed control is said by Kleemann to ensure consistently high utilisation.

The company says it counters the increasing complexity of crushing plants with its intuitive operating concept Spective.  

In addition to a large touch panel and two Spective radio remote controls - one of them for operating all relevant functions of the automatic mode from the comfort of the excavator - Kleemann also offers Spective Connect.  

The digital solution simplifies the construction site digitisation of the Mobirex MR 130(i) PRO. Spective Connect transmits all important system data to the user's smartphone and simplifies reporting.

With the Mobirex MR 130(i) PRO, the proven, robust crushing unit with its two impact rockers and versatile blow bar options, as well as the 8.4m² optional double-decker post-screen, are said to ensure very good product quality.  

Kleemann’s new impact crusher can produce and discharge two classified end sizes – without using an additional screening plan. The use of optional wind sifters is said by the German company to further increase end product quality.

The SM-22 is the biggest rig in the SM line and is an evolution of the PSM-1350 and SM-20 models, retaining the efficiency and of the earlier machines. The machine was developed with a kinematic system capable of guaranteeing a variety of angles and positions in different construction site conditions and with different drilling methods. Power comes from a Cummins B6.7 diesel, available in a Stage V version.

The machine has two fixed stabilisers in the rear and two extendable hydraulic stabilisers in the front, rotating and pivoting, for stability in difficult conditions. The machine is equipped with openable hydraulic cages, ROM and SPM operating modes and all accessories to ensure accessibility, visibility and safety.  

The Soilmec SM-22 is versatile due to its modular design it can be easily configured in different configurations. It can be used for single rotary, double rotary, top-hammer and vibro-rotary applications to perform consolidations, micro piles and anchors with different drilling technologies, direct circulation, reverse circulation, DTH, CFA, jet grouting. 

Because it combines the benefits of the company’s proven modular universal formwork and the LOGO.3 wall formwork system, NeoR can be used universally, making it ideal suited for construction of foundations, beams, columns, and walls.

The formwork panels of the NeoR lightweight formwork have a maximum weight of just 41.3kg on the element 900mm x 1500mm. It can easily be assembled and moved in twos and smaller panels solely on site by hand without a crane or other transport aids.

At the same time, the NeoR lightweight formwork boasts significantly higher fresh concrete pressure absorption of 50kN/m² - an improvement on the Modular system’s 30kN/m².

A further advantage of the new formwork system is the low overall height of only 750mm, which ensures particularly low storage and transport volumes.

NeoR can also be assembled in both upright and sideways direction so there is no need for a second system of different dimensions, making a client’s investment in formwork go further.

The optimum panel assortment ranges from formwork panel widths of 150-900mm in 150mm increments, which will be available in both 900mm and 1500mm heights. As a result, a floor height of up to 3m can be built with just one extension of the panels.

With NeoR, even large areas can be moved quickly and economically without any problems – this is where the large-size panel with 1800mm x 3000mm comes in useful. The range is supplemented by 50m and 60m filler posts for width adjustments and matching plastic filler pieces.

With four new electric mobile elevating work platforms (MEWPs) models, Manitou Group is accelerating the roll-out of its ‘Oxygen’ low emissions range.  

The 100% electric line, which comprises the 200 ATJe, 160 ATJe, 180 ATJe 160 ATJ+ e rough-terrain platforms, is part of a larger rollout of seven electric models.   

With a working height of 20m, the 200 ATJe rough-terrain platform is available with four-wheel steer for greater manoeuvrability. The machine is equipped with a basket that can now take 250kg of load, 30kg more than the two-wheel drive counterpart.  

Apart from zero emissions, another big benefit is reduced total cost of ownership (TCO). Customers can expect a 50% reduction in maintenance costs compared with the internal combustion version.  

With a working height of 16m and 18m respectively, the 160 ATJe and 180 ATJe see their capacity increased by 50kg, with a basket that can take a total weight of 250kg. The 160 ATJ+ e, the biggest platform in the range, comes with a 400kg capacity.  

With these new products, Arnaud Boyer, vice president of Marketing & Product Development, says Manitou is the first manufacturer to have a range of 100% electric rough-terrain platforms from 16m to 20m.  

According to Boyer: “The acceleration of our electric development allows us to now offer low-emission solutions across our platform ranges, as well as on our telehandlers. We will continue to extend this energy to other ranges in accordance with the objectives of our CSR roadmap.”

“The new electric MEWPs are testimony to our low carbon trajectory. By 2040, 43% of our offering should be lower emission machines – either electric or hydrogen powered,” added Michel Denis, president & CEO of Manitou Group.

The new Mecalac MCL range includes six models with loading capacities from 1.74 -2.85tonnes. Four long-boom models will appeal to agricultural users and two models with short booms should better fit the needs of construction customers.

The MCL2’s diminutive size and wheel motor transmission allow it to move with agility. The smallest machine in the MCL range but with maximum performance, it has all the features of the big ones. Its modern and ergonomic operator’s station protected by a canopy is also available in a cabbed version.

The MCL4 is said by Mecalac to offer an excellent compromise between compactness and performance. With its 18.4kW engine, it is ideal for rental fleets that want a durable and high-performance machine. Its low transport weight also allows the machine to be transported on a road trailer.

Based on the MCL4 but with even more power, the MCL6’s 36kW motor allows it to reach and maintain high speeds on the road. Its high hydraulic flow rates, and its speed of execution are said to allow it to considerably increase the productivity on worksites.

Power, high dumping height, and lifting capacity are the key benefits of the MCL8. The MCL4+ / MCL6+ are short arm versions to meet the specific needs of different applications, especially in the construction sector, offer an increased tipping load.

All MCL machines are available in three versions: canopy, canopy with foldable top, or cab, and all of them come with a wide selection of attachments.

The battery-powered units offer zero emissions and are quiet in operation, making them ideal for noise-sensitive work sites, especially in urban locations. The batteries are charged using a conventional electric supply, and the machines can work while charging.  

In order to change to battery operation, the operator simply takes out the plug while performance remains unchanged. All six models are now available in both conventional and battery-operated versions with identical performance. The LRH 100.1, LB 25, LB 30, LR 1130.1 and LR 1160.1 were previously available with diesel power only but are now offered in electric versions too. However, the LRH 200 is brand new.

The LRH 200 closes the gap between the proven LRH 100 and LRH 600. A 200kWh battery pack ensures that the unplugged models can operate in battery mode for 4-5 hours in average pile driving applications. Optionally, it can be upgraded to 400kWh for 8-10 hours of operation.

The new design of the LRH 200 extends the range of applications. In addition to piling, the machine can be used for continuous flight auger, full displacement and down-the-hole drilling, as well as for soil mixing work. A torque of 250kNm provides the power.

When equipped with the hydraulic hammer H 6 from Liebherr, the LRH 200 and the LRH 200 unplugged can lift piles up to 24.5m long and weighing 16tonnes. The LRH 200 is said to offer a large working range, with a radius of up to 8.7m. The design of the leader enables inclinations of up to 18° in all directions. It is also possible to raise or lower the leader by 6.5m, which makes the machine more versatile.

The Blue Tech Line features optimised power transmission and reduced energy losses. The new motors adjust speed automatically according to needs, improving combustion and cooling efficiency and reducing working noise.  

The rotary heads have been developed with a wide range of solutions to reduce losses and increase performance. Optimised lines, dedicated distributor on rotary and power control through DMS for torque and speed best compromise to name some of them.  

The main winch is provided with a dedicated control specially designed for drilling rigs. The system runs at higher pressure with less fluid flowing. That reduces loses and allows easier and more precise control, especially when drilling deep piles. The design of the Blue Tech drilling rigs together with plug and play kits allows a quick conversion between the different versions and technologies.  

The new SR-125 has been updated to the Blue Tech version and includes a redesigned operator cab and new hydraulic and mechanical systems. The machine has improved characteristics compared to the previous model, with an increase in the torque value and in the main winch.

The MT 625e, with a lifting capacity of 2.5tonnes and a height of 6m, is said to deliver the same performance as its comparable internal combustion counterpart. Fitted with a 25kWh or 33kWh lithium-ion battery, the model reduces maintenance costs by 56% and noise levels by 12%.  

Perfect for indoor or city centre use, the MT 625e, like all the other models in the Manitou compact telehandler range, benefits from the new Safety Pack, designed to protect the operator and the site teams, as well as alerting fleet managers to any high-risk behaviour.  

“Key features of the Safety Pack include harness detection and identification of obstacles around the machine’s chassis,” said Arnaud Boyer, vice president of Marketing and Product Development at Manitou.  

“A ‘lighting’ pack ensures the utmost safety for platform loading and unloading operations with a number of lights positioned on the platform to maximise visibility,”  

The first commercial units will be shipped to the global market by mid-2023, Laurent Bonnaure, executive vice president at Manitou, added. 

Wacker Neuson has been using the battery since 2014 and it now works with eleven different products. Since 2021, the battery has also been deployed in BOMAG’s electrically powered rammers.  

Battery One is a lithium-ion battery for lightweight compacting equipment. There are three types: 500w/h, 1000w/h and 1400w/h. The lightest 500w/h battery is used on a backpack with an internal vibrator system for concrete.

To ensure instant recognisability among customers and users, these interoperable batteries and chargers are all marked with the Battery One branding. Wacker Neuson’s interoperable products are already identified with the branding, and BOMAG, Mikasa, Swepac and Enarco will also soon be adding the Battery One logo to their compatible batteries.

Wacker Neuson says that battery-powered construction equipment is becoming an increasingly attractive option for construction companies, especially with investments in a battery and charger now being compatible with a growing range of equipment from different vendors.  

The Munich-based equipment group manufacturer says that future-fit battery technology is a key driver for the development and incentivisation of sustainable products that will resonate strongly with customers. Building on recent positive experiences with Battery One, Wacker Neuson adds that it intends to collaborate with the above-mentioned manufacturers to establish an open standard for construction equipment batteries.  

To discuss the possibility of a battery standard, the vendors will engage in negotiations to establish the exact nature and implementation timeline for the concept while respecting antitrust requirements in particular. Wacker Neuson says this collaboration is inspired by the idea that customers would benefit from cost savings when they invest in battery-powered products, creating strong momentum for the wider uptake of zero emission equipment on construction sites.  

It adds that such an establishment of such a standard would also simplify construction site workflows and logistics by eliminating the need to manage different battery and charging systems. The aim is to make the battery system available to further manufacturers in the construction sector.

“The availability of a multi-vendor interchangeable battery for construction equipment is key to the growing adoption of electromobility on building sites,” says Stefan Pfetsch, managing director of Wacker Neuson Produktion. “Compatibility provides huge benefits for the customers. We see demand for battery-operated equipment growing all the time. With Battery One, we make it easier for customers to go electric – in particular to switch from products that were previously powered by conventional drive technologies.”

BOMAG president Ralf Junker adds that Battery One’s compatibility across different brands and products will further increase the penetration of electric equipment and the sustainability of battery lifecycle management on construction sites. “Together with our customers, we are helping to make construction sites around the world more environmentally friendly,” says Junker.

Hironari Kyoya, president of Mikasa Sangyo, adds: “A powerful and interchangeable battery solves a number of challenges on the building site, such as the need to extend battery runtimes, accelerate charging times and lower equipment and infrastructure costs. All of this adds up to greater convenience for our customers.”

Additionally, the new VARIO injection bar for binding agents allows the user to regulate the injection pressure of water and bitumen to achieve more homogeneous distribution in the mixing chamber.

The RES combines an automatic steering system and digital project site documentation in a single app, improving the cost-effectiveness and resource-efficiency of soil stabilisation and recycling operations.  

The satellite-based guidance system allows precise completion of project tasks and steers the machine with a precision measured in centimetres, on the basis of a previously calculated reference cut and a predefined overlap of adjacent cuts.  At the same time, location-specific parameters are recorded to generate a database for site analysis and documentation.  

Parameters such as working width and depth, distance/area worked and fuel consumption are recorded. The system is scalable, which means that other machines such as rollers and compactors involved in the process can also benefit from the data.

To achieve high-quality mixing, the addition of water and binding agents is regulated according to parameters such as the working width and depth, the material density and the machine advance rate. Each injection bar has 16 nozzles, each of which can be activated or deactivated to vary the spraying width.  

The novel VARIO injection bar for water, bitumen emulsion and foamed bitumen features an adjustable nozzle cross-section that allows injection pressure regulation and the depth the spray jet penetrates into the milled granulate.

The technology is currently being developed by the company and researchers at Montanuniversität Leoben, Austria’s university for mining and metallurgy.

The REMAX 600 features a cutting-edge sensor system, video technology, powerful communication and IT networks. It will offer a set of technological innovations, such as an automatic gap adjustment facility.

It can offer up to five fractions in one cycle. With a feed capacity of 600t/h, the new machine can accommodate material feed sizes up to 900mm and a maximum total weight of 75 tonnes depending on the equipment.  

Triple wind sifting and an ultra-efficient overbelt magnetic separator with longitudinal discharge as an option (a novel feature in highly mobile impact crushers) are said by SBM to ensure high purity of final products, even in recycling applications.

SBM stresses that the industry-first introduction of an 'autonomous crusher' will help users and operators with all decisions, permanently support efficient operation, assure optimum product quality at all times, as well as make an important contribution to save energy and costs during crushing.

The autonomous crushing R&D project has been running for two years and features interdisciplinary teams from the Montanuniversität Leoben chair of mineral processing and SBM research departments.  

The project aims to make the decisive step from today’s already extensively monitored and optimised crushing operations to autonomous fully automated production by means of ‘intelligent self-learning’ mobile crushers.

The machine independently assesses feed material and final products via sensors and camera systems, registers better-than-before-the-load conditions of crusher and conveyor equipment, and optimises all separation processes down to overbelt magnetic separators and wind sifters.

The SBM control system, Crush Control, validates all operating conditions and material properties in real-time and sends the values to SBM’s headquarters via the cloud. A ‘digital twin’ compiled there matches the real machine data with thousands of stored reference data coming from 1:1 quality testing, laboratory tests and computer simulations (including rock properties, grain-size distribution curves, particle shapes, etc).

The optimisation potentials determined from this are sent back to the machine control system in real time. This allows immediate and permanent adaptation of all process steps on site without any stoppages, says SBM.

By means of an interactive menu control, SBM says even inexperienced operators can precisely adjust the production process – depending on whether maximum output, minimum fuel consumption (eco mode) or quantity-optimised production of certain valuable grain sizes are required.

The newly integrated tool monitoring system in the REMAX 600 is another benefit, one which counteracts shortfalls in quality due to wear during production and provides key support for preventive maintenance.

Large-scale test runs will take place in the coming year to make sure everything works as it should in practice. 

Mecalac says it is helping to revolutionise urban construction sites and paving the way for intelligent, clean and silent workplaces.

Climate change and the resulting need to reduce CO₂ emissions has become a major global challenge. In recent years, many construction equipment manufacturers have presented electrical products to limit CO₂ emissions.  

However, Mecalac notes these alternatives only provide a partial answer, as the offer is currently mostly limited to small machines - such as 1.5-ton mini-excavators - that tend to only assist larger, diesel-powered machines.

Mecalac says that the need for medium-sized machines on urban construction sites is not yet met. With very limited autonomy (generally between 1.5-4 hours), they do not allow a full day of work on site between battery recharges. Companies and operators are used to combustion-powered machines, so the switch to electric vehicles is not seamless.

With these problems in mind, Mecalac has carried out a major R&D programme, which has led to the launch of its complete zero-emission eco-system for urban worksites. With the trio of complementary machines, all earthmoving operations (digging, loading, and transporting) can be carried out with emission-free machines.

Mecalac notes that the absence of medium-sized electric machines has been due to difficulties with optimising power management to ensure sufficient autonomy. To overcome this problem, Mecalac says it has made a technological breakthrough on the hydraulic distribution system, as well as on the energy management of auxiliary systems such as heating and air conditioning, to drastically reduce energy consumption without compromising autonomy and performance.

The style of driving that operators have adopted for decades behind the steering wheels of combustion-engined machines is, adds Mecalac, not always compatible with optimising battery performance.  

For example, when the throttle pedal is pressed, all the power of an electric machine is instantaneous, unlike combustion-engined machines. Mecalac has therefore configured the human-machine interface so that it reacts in an optimal way to preserve autonomy and guarantee coherent behaviour.

M-Power is a mobile high-power supply solution. With its 300kWh storage capacity, it replaces traditional diesel generators by providing a battery charging solution anywhere. Mecalac says that its electric eco-system is a game-changer that enables a drastic reduction in CO₂ emissions on construction sites.  

For example, three Mecalac zero-emission machines working together on the same urban worksite save an average of 64 tonnes of CO₂ that their combustion-engined equivalents would have emitted over a year.

Mecalac’s zero-emission offer is also a response to limiting noise pollution and now offers new capacities for working inside. 

The manufacturer says the 16tonne machine is equipped with a hydrogen fuel cell, providing the electrical power to operate the machine with zero tailpipe emissions.

The machine is suitable for use in road building and urban construction, and the manufacturer plans to commercialise the technology utilised in the concept model from 2025.

Hyundai Construction Equipment has been developing a hydrogen fuel cell-powered driveline since 2020, when it signed a memorandum of understanding with Hyundai Motors and with specialist division Hyundai Mobis, at its Mabuk Research Centre in Yongin-si, Gyeonggi-do.

Together, the three companies have committed to develop hydrogen fuel cells to power forklifts and medium/large excavators over the coming years. Unlike a diesel-powered wheeled excavator, the hydrogen-powered machine has a fuel cell mounted in the rear of the upper-structure.

The fuel cell relies on a chemical reaction between the stored hydrogen and oxygen that is present in the air. The fuel cell stack generates electrical energy from this reaction, with an inverter converting this energy into usable electrical power.

This is used to drive the hydraulic pump, to power the machine in the normal way. Hyundai says the only emission from the fuel cell stack is water, a combination of the hydrogen and oxygen. It adds that when the hydrogen is produced using renewable energy, such as off-shore wind, this creates an incredibly low carbon powertrain. For the excavator, the hydrogen is stored on the right-hand side of the machine, opposite the operator’s cab, in high-pressure tanks.

This technology is already in use in Hyundai’s Nexo fuel cell passenger car. HCE says this transfer of technology to the construction equipment market will provide it with a ground-breaking wheeled excavator package, delivering all the power and performance that a contractor requires, with zero on-site emissions and the ability to refuel from a hydrogen station in minutes, even in the most remote locations.

“The development of the first excavator powered by hydrogen is very exciting, as we work towards a carbon-free world,” says Gert Peeters, product manager at Hyundai CE Europe. “Over the coming months, HCE will continue to develop and further refine this technology and thereby pursue our goal to lead the transition into a zero-carbon future.”

Among the features of the new Dynapac CG3300 VI are its latest generation VI operating station, interface, electric system, and ECU software. Additionally, the Dynapac CG3300 VI will come with a new style for forks, beams, and frames.

After comprehensive testing and adjustments to a hot asphalt mix, similar results were achieved with the novel SEISMIC technology in asphalt compaction as those for soil compaction. Benefits include reduced vibration power and energy consumption by 20-30%, and a 7-9% fuel consumption reduction.  

Additionally, noise levels are lowered due to lower frequency and there was an overall reduction in the number of passes depending on the application. The generation VI CGs will also be available as combi versions with a split drum front and rubber wheels rear.

The new operator station for the CG3300 VI station offers full seat rotation, making it possible to turn the seat and steering module all the way around for visibility. The machine has an electric steering wheel and an instrument panel that is said to be easy to understand.

The patented Efficiency Eccentrics system optimises eccentric elements, providing further fuel and energy savings during operation. The included ECO-mode, with its best point system and serial start-up, helps ensure lower emissions.

The CG3300 VI has a length of 4.2m, with a 1,680mm drum width, 1,200mm offset, and an operating weight of 9tonnes. It comes with a static linear load of 26.8kg/cm. The CG3300 VI also comes with the Dyn@Link advanced system, which keeps track of parameters and operating processes.
