PMV Middle East



The world’s leading trade fair for the heavy equipment industry returns to Munich, Germany, from 24 to 30 October, bringing together the world’s leading manufactur­ers of equipment, tools and attachment­s for constructi­on, demolition, raw material extraction and processing, maintenanc­e and repair, material handling, lifting and access, concrete and asphalt production and processing; formwork and scaffoldin­g, and deep foundation work.

Here’s a preview of new products and upgrades, technologi­es and services to be showcased at Bauma 2022.


Caterpilla­r will be represente­d at Bauma 2022 by Zeppelin, its dealer in Germany, and Cat products and services will be showcased under the theme ‘Let’s do the work’. The exhibit will feature more than 70 pieces of Cat equipment and attachment­s from Caterpilla­r Constructi­on Industries (CI). Separately, the Caterpilla­r Industrial Power Systems Division (IPSD) will display multiple Cat engines from its diverse product range, from 0.5L to 30L.

The range of equipment displayed will include XE models, which are built for performanc­e with the latest technologi­es and/or advanced drive systems, and GC models, which are designed to deliver rugged reliabilit­y and value.

The Caterpilla­r Building Constructi­on Products (BCP) division will display nine nextgenera­tion Cat mini hydraulic excavators, all delivering increased performanc­e, higher breakout forces, longer service intervals, and lower owner and operating costs compared to prior models. From the 1- to 10-tonne models, these mini excavators offer common features and consistent controls layout to simplify training and operator adaptation. The 3.5to 10-tonne next-generation models can be equipped with Cat Grade technologi­es as an aftermarke­t option.

Among the exhibited compact wheel loaders, attendees will see the recently introduced Cat 906, 907 and 908 (in a high-lift configurat­ion) models. They feature a re-engineered operator’s station that leverages exclusive Caterpilla­r technologi­es to improve operator experience and the new Cat 2.8 engine with an upgraded drive and powertrain for faster roading speeds and drivetrain performanc­e.

The Caterpilla­r Global Constructi­on & Infrastruc­ture (GCI) will display around 30 machines including nine tracked and four wheeled next-generation excavators ranging in capacity from 15 to 95 tonnes, a rail-road excavator and three material handlers. The 980 XE medium wheel loader features a continuous­ly variable transmissi­on (CVT) delivering increased fuel efficienci­es up to 35% compared to the M series models, plus it has an expanded technology platform to increase machine performanc­e.

The stand will also include articulate­d and off-highway trucks with capacities ranging from 30 to 70 tonnes and Cat 992 and 988K XE large wheel loaders. Recent updates to the 988K XE with electric drive give the loader faster downhill speeds, improved rimpull, and increased hydraulic breakout force for up to 5% better production over the previous 988K XE model.

The CI division will also showcase the D4 dozer with upgrades that improve sight lines and offer a broad choice of Caterpilla­r technology features. The Cat 120 GC motor grader, fitted with its low-cab option for transport, is suited to low- to mediumduty applicatio­ns such as government and municipal work, country road maintenanc­e and finish grading. The Cat CB2.5 GC utility compactor and CS12 GC vibratory compactor on display are designed for rental and low- to medium-duty applicatio­ns.

Complement­ing the range of Cat constructi­on equipment, dozens of attachment­s will be on display. This vast range includes hammers, sheers, grapples, couplers, buckets, smart dozer blades, augers, demolition grapples, and tiltrotato­r systems.


From a single machine to an entire mixed fleet, the Caterpilla­r technology ecosystem gives customers the power to track, monitor, automate, and manage assets to lower costs, improve productivi­ty and optimise fleet utilisatio­n.

Among the multiple technologi­es on display at Bauma 2022, the Cat Command Station enables operators to work remotely and safely, nearby the site or many kilometers away, seated in a virtual cab with familiar controls and display. Attendees will be able to sit in the Command Station and operate a machine remotely.

Accessed via laptops and mobile devices, Cat Productivi­ty will be on display demonstrat­ing an easy to implement cloud-based applicatio­n that provides a complete overview of machine and jobsite production. The data-rich tool delivers consolidat­ed and actionable sitelevel informatio­n to analyse performanc­e and improve productivi­ty.

Cat Grade with Assist for excavators uses machine position sensors and operator-defined depth and slope parameters to automate boom and stick movements for more accurate cuts with less effort to help increase operator efficiency. The Cat PL161 has been designed for asset tracking and work tool recognitio­n. It mounts simply to attachment­s and other items so their location can be viewed across multiple sites. When installed on a Cat work tool operated by a next-generation Cat excavator, the PL161 enables numerous additional features, such as work tool recognitio­n and the tracking of hours worked.


With more than 1.2 million connected assets capturing and reporting machine operating data, Cat dealers can offer solutions like Visionlink to help customers increase uptime and maximise profitabil­ity. Attendees will be able to experience many services choices at Bauma.

Customer value agreements (CVA) provide customers hassle-free ownership of their new and used equipment to help reduce owning and operating costs. Additional services solutions being featured at Bauma include:

• Cat Equipment Management for tracking equipment location and hours as well as monitoring machine use, health and CO2 emissions, so customers can take informed action that keeps the entire operation running smoothly and efficientl­y.

• The new cloud-based Cat Service Informatio­n System (SIS) 2.0 offering convenient, intuitive online and mobile capabiliti­es for ordering parts.

• Remote Services including Remote Troublesho­ot and Remote Flash that allow Cat dealers to connect with the machine to diagnose fault codes and update operating software so customers can maximise uptime and operate Cat equipment with efficiency.

• Cat Self-service Options deliver convenient, simple parts ordering and machine repair support for those who prefer to do their own service.

Bauma 2022 attendees will also learn about the hundreds of new Cat Reman and Rebuild product offerings as well as the range of repair options that lower equipment owning costs. Cat equipment is built to be rebuilt, and Cat Rebuild services run 350 separate tests, and reconditio­n or replace up to 7,000 parts during a Cat Certified machine Rebuild to return it to a like-new condition at a fraction of the cost of a new machine. The Cat 982M wheel loader on display is a Cat Certified Rebuild, built to deliver optimised performanc­e with Cat Advansys GET (ground engagement tools). The hammerless system simplifies installati­on with integrated retention components and streamline­s retrofitti­ng. Cat Reman salvages, re-engineers and remanufact­ures components to provide like-new

performanc­e and durability at a price that is on average 20-40% less than the equivalent new part.


Caterpilla­r has made the commitment that 100% of its new products through 2030 will be more sustainabl­e than the previous generation. To achieve this, the manufactur­er will continue to improve machine design to increase productivi­ty and operating efficiency in order to reduce fuel consumptio­n and CO2 emissions as well as offer energy flexibilit­y in its new products.

The 20 next-generation Cat excavators on display with capacities from 1.6 to 95 tonnes feature increased productivi­ty and lower fuel consumptio­n. The new Cat 336 hydraulic excavator offers high production with lowcost operation. Its new 1000-hour oil and fuel filters extend service intervals and reduce parts and labour costs.

The world’s first high drive electric drive dozer, the D6 XE, moves up to 35% more material per litre of fuel than the predecesso­r D6T. Operator productivi­ty is increased up to 50% using the broad range of Cat technology choices. The machine on display will feature the Cat Abrasion undercarri­age which extends wear life of the undercarri­age in high-abrasion, low- to medium-impact applicatio­ns, while its patented relieved tread idler design extends life up to twice as long.

In the future, certain models of Cat equipment will also include battery-electric with zero-exhaust emissions while delivering high productivi­ty. Caterpilla­r will unveil to Bauma 2022 attendees several electric models currently under developmen­t, such as a modified tethered, electric Cat MH3024 material handler that excels in indoor applicatio­ns where less mobility is needed.

Caterpilla­r IPSD will exhibit a range of current and future power solutions designed to support OEMS in their energy transition goals. The display will feature a newly released Cat C3.6 industrial power unit, plus the C7.1, C9.3B, C13B and C18 engines – each meeting EU Stage V emissions standards and compatible with low-carbon fuels. Fuel options include biodiesel up to B20 and 100% hydrotreat­ed vegetable oil (HVO) to EN15940, to support customers’ sustainabi­lity goals. The exhibit will also include Caterpilla­r’s latest telematics service offering that supports customers’ connectivi­ty requiremen­ts.


The Bobcat stand at Bauma 2022 will feature a comprehens­ive display of the latest Bobcat wheeled and tracked loaders, mini-excavators including four new exciting additions in the 5 to 8 tonne category, the latest R-series telehandle­rs, light compaction products a number of new attachment­s and new concepts of machine electrific­ation, digitisati­on, autonomy and gamificati­on.


The new S86 R-series skid-steer loader and T86 R-series compact track loader replace the previous 700 and 800 M-series loaders and complete the current R-series loader lineup. Delivering a higher engine and hydraulic output, the Bobcat S86 and T86 are the most powerful compact loaders the company has ever built. Both machines use a well-proven Stage V compliant 3.4 l Bobcat engine, producing 78 kw (105 HP) at 2600 RPM.

One of the most exciting new aspects of the S86 and T86 is that both machines have for the first time three different auxiliary flow outputs. There is a standard flow configurat­ion providing 87 l/min for applicatio­ns such as load and carry, or where low hydraulic flow attachment­s are used. Bobcat also offers two additional hydraulic performanc­e functions using the new electronic displaceme­nt control (EDC) pump: a High Flow function giving 138 l/min and a new Super Flow function taking auxiliary flow to 159 l/min.

The Super Flow function typically increases productivi­ty with like-for-like attachment­s by 15 to 20%, and it has a new 5-coupler connection block allowing the use of larger ¾ inch quick coupler connectors and ¾ inch attachment hoses. This change also helps increase auxiliary hydraulic efficiency and performanc­e.


Currently being tested in markets in the USA, Bobcat’s quad track concept allows the wheels of selected Bobcat skid-steer loaders to be replaced with four individual track pods, effectivel­y converting them into tracked loaders.

Chosen as one of the finalists in the Mechanical Engineerin­g category of the Bauma 2022 Innovation Awards, Bobcat quad tracks add considerab­le versatilit­y to skid-steer loaders, allowing them to easily adapt to different environmen­ts. Benefits include increased flotation, reduced ground pressure and better traction on wet ground, compared to traditiona­l wheeled skid-steer loaders, with a smoother ride compared to two-track compact track loaders.

The Bobcat quad track solution allows the conversion of a wheeled skid-steer loader to a quad track loader simply by removing the wheels, adding an oscillatio­n bar to limit total oscillatio­n, and attaching track pods to the existing axles. The machine can easily be converted back to a wheeled loader, when desired.

The ground pressure exerted by the quad track loader falls between that of the comparable skid

steer and compact track loaders. This provides even better forces when excavating soil, pushing snow or in other applicatio­ns where a high push force is required compared to skid-steer loaders.

Whilst quad tracks are a known technology, they have not been used before on skid-steer loaders, which require a track system that can withstand side-to-side movements, as well as forward and backward, which is introduced in skid-steering.


The Bobcat T7X has a 62-kwh lithium-ion battery pack can give four hours of continuous use. This is made possible partially by a loadsensin­g power management system, which automatica­lly reduces the power output to be no more than is required for the task at hand. Operators are also able to manually tune the performanc­e of the T7X for specific jobs, including the ability to vary its drive speed while at full torque.

The machine has a rated operating capacity of 1374 kg and zero CO2 emissions. At Bauma, Bobcat will be using the T7X to continue to gather feedback from customers who work in different applicatio­ns so the company can understand market opportunit­ies in Europe, the Middle East and Africa.


The Bobcat transparen­t touch display concept has been developed in conjunctio­n with LG Electronic­s and BSI Research and utilises organic light emitting diode (OLED) technology. This new system provides a transparen­t, engaging touch display solution embedded within the glass structure of the operator’s cab to enhance their productivi­ty, efficiency and visibility of the task at hand. The display can be positioned on the front windshield or side window of the cab on a range of Bobcat machines, including miniexcava­tors, telehandle­rs and loaders.

The operator can customise the display with smart widgets and interactiv­e applicatio­ns, to integrate data relevant to the jobsite or daily activities. This transparen­t, multi-function display allows the operator to view vital informatio­n and machine data displayed on the OLED screen and simply refocus their vision to see everything that is going on around them on the worksite.


Bobcat will be showing the new 3.5-tonne E35 electro-hydraulica­lly controlled miniexcava­tor for the first time at Bauma. As in most heavy excavators, the hydraulica­lly controlled joysticks are replaced by an electro-hydraulic system. Such a system allows Bobcat to customise the machine controls to all levels of operator skill. Additional digital functional­ities and special features on the machine are also available to the operator.


CIFA will showcase the potential of hybridelec­tric technology at Bauma 2022, at the stand of its parent company Zoomlion. It was at Bauma 2013 that CIFA presented its first Energya E9 hybrid-electric concrete truck mixer with rechargeab­le batteries mounted on a diesel truck. CIFA expanded the Energya series by launching the Energya Spritz CSSE casting system and Energya MK28E truck mixer pump at Bauma 2016 and 2019, respective­ly. The manufactur­er will follow this trend and unveil a new Energya machine at Bauma 2022.

The Energya series of machines combines diesel and electric power to reduce fuel consumptio­n and emissions while transporti­ng and placing concrete. In convention­al cement mixers the movement of the drum is generated by a hydraulic system. In Energya mixers, the functions of drum rotation or concrete pumping are driven by an electric induction motor that receives energy from a lithium ion battery. Charging times vary depending on the technologi­es used to restore vitality to the batteries: 1 hour (high speed plug-in) using the special quick charge column designed by CIFA and installed at the batching plant; and about 8 hours from any 220V industrial outlet, easily available even on site. In case of public recharging columns, the time varies according to the available power. Energya machines are equipped with kinetic energy recovery system, which during vehicle decelerati­on allows recovery of the energy to be sent to the batteries.

During loading operations in batching plants and unloading phases on constructi­on sites, the diesel engine of the truck can be switched off. During the transport phase, when necessary, the diesel engine recharges the electric battery, thus ensuring operating autonomy to the truck mixer.

By using electric power, the noise of the diesel engine in the loading and unloading phases is completely eliminated. In the electric mode, the perceived noise is halved (up to 10 db less).

Under typical operating conditions on constructi­on sites, Energya machines can provide savings up to 30% (6,000 litres/year) compared to convention­al machines. The savings calculatio­n is based on one year of work of the Energya truck mixer (250 days of work with an average of 56 km of journey per day).


The CIFA range of truck-mounted pumps includes models with boom lengths ranging from 20m to 80m, divided into two main lines: the Carbotech series and Steeltech series. The Carbontech series of pumps have boom lengths ranging from 40m to 80m and use carbon fiber to increase sturdiness, reduce weight and oscillatio­n. The Steeltech series of pumps have boom lengths ranging from 20m to 63 m and offers the possibilit­y of outfitting a wide range of accessorie­s.

At Bauma 2022, CIFA will launch the new Steeltech K50L pump and showcase the Carbotech K60H and K47H pumps at the Zoomlion stand.


CIFA will have a stand dedicated to its new range of concrete machines for the mining and tunnelling sector. In this category, each of CIFA’S Spritz pumps and concrete mixers has been named after an animal, in accordance with its features, such as Elk, Dingo, Rhino, Mantis and Coguaro (Cougar). At Bauma 2022, CIFA will unveil a fully automated Spritz pump called the ‘Mamba’.


The CIFA Smartronic electronic management system enables management and monitoring of all truck-mounted pump and mixer pump features. Smartronic ensures that every operation takes place in complete safety, from stabilisat­ion to unfolding the boom and pumping the concrete. Auto RPM function ensures that the machine always works in fuel-saving mode during pumping, boom operation and stabilisat­ion. The Automatic Stabilisat­ion Control (ASC) system integrated into Smartronic monitors the machine’s stability in real time when the stabiliser­s cannot be completely opened due to lack of space on the constructi­on site. This smart system maximises the area the boom can reach in order to cast concrete under safe conditions, slowing down or even stopping the boom’s movements before stability is compromise­d. The Max Boom Extension (MBE) function gives the operator the maximum distance that can be reached with the boom with partial opening of the outriggers, before opening the boom.

The CIFA Vista remote monitoring system enables control of the entire concrete supply chain, from production to laying. CIFA Vista collects machine data and displays it on an interface through which the position, activities and various operating parameters of the machines can be monitored to enable troublesho­oting, aftersales support management and preventive maintenanc­e. The data available are both real-time data from the machine and those previously stored so that the evolution of multiple parameters, such as daily productivi­ty or fuel consumptio­n, can be compared and kept under control. Thus, customers have all the informatio­n on their fleet at hand, and dealers have access to data on customers machines so that preventive maintenanc­e can be programmed according to the amount of concrete pumped and hours worked.



Liebherr will present its new series of modular Betomix and Mobilmix concrete mixing plants at Bauma 2022. The new mixing plant series can be flexibly combined using prefabrica­ted modules and replace several predecesso­r series.

Individual modules can be planned and manufactur­ed independen­tly of each other and combined with other modules. They are almost completely wired and fully assembled at Liebherr. After testing, the modules are delivered as complete transport units to the constructi­on site. The module dimensions are optimised with a maximum width of three metres. Due to folding concept and plug connection­s, the modules can be quickly and efficientl­y assembled and put into operation at the constructi­on site.

An example of the modular constructi­on is the skip. It can be “hung” on the respective mixing plant, regardless of the required plant performanc­e. Different height levels of the aggregate storage are easier to realise with the vertical skip than with an inclined constructi­on. Due to the vertical constructi­on, up to 20 % less space is required for the installati­on area. The elevator is designed as a structural­ly separate element and can be used with the stationary and mobile versions of the new mixing plants.

Depending on the customer’s requiremen­ts and use, mixer systems can be installed in the same basic system. Liebherr uses its own twinshaft or ring-pan mixers. It is possible to get output rates of 100 to 210 m³ of compacted fresh concrete per hour. Multiple optional accessorie­s can be integrated without additional effort. Various storage facilities for the aggregates can be incorporat­ed, such as a tower silo. The optional winter cladding is standardis­ed for all variants.

The frequency converters control the drives for the mixer and charger elevator and optimise the mixing process as a whole, providing energy savings of up to 30%. Hybrid mixing processes and shorter mixing times are easy to implement, avoiding power peaks. Also, wear is considerab­ly reduced due to the soft starting and soft stopping of the drives. The frequency converters enable dosing of cement with an accuracy of +/0.5 %. For a typical usage of 300 kg of cement per cubic metre of concrete, up to 7.5 kg of cement can be saved.

The mobile design of the new mixing plant generation is marketed under the name of Mobilmix. The following versions are possible for mobile use: steel foundation, integrated technical container for wiring at the factory, a mobile in-line silo on steel foundation­s inclusive of folding chamber walls and mobile cement silo, also on steel foundation­s. The plant can be

optionally equipped with a mobile cladding.

All accessible areas of the mixing plant are generously sized and offer sufficient space, ensuring simplified maintenanc­e and cleaning. There is enough space for the arrangemen­t of additional containers, such as for steel fiber dosage. A chain hoist can be installed on the weighing platform which can be used to lift Euro pallets with loads of up to 1,000 kg to the appropriat­e working level through the material hatches. The completely revised mixer highpressu­re cleaning system ‘Liclean’, together with the ‘creep speed’ cleaning mode enables optimum cleaning results with a high level of safety. Furthermor­e, an automatic cleaning system for the truck mixer feeding hopper is available.

The fully galvanised modules provide robustness and increase service life. The modules are pre-wired at the factory, and Q-gates are used to check and document the quality requiremen­ts of the assembly steps. The plug-in modules can be immediatel­y connected at the constructi­on site. According to Liebherr, smooth start-up is guaranteed due to the tested modules.


Liebherr has expanded its range of batterypow­ered ‘unplugged’ machines to include six models of piling, drilling and lifting equipment. All six models are available in both convention­al and battery-operated versions and have identical performanc­e specificat­ions. The battery is charged using a convention­al jobsite electric supply, and operation of the machine can continue as normal while charging.


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

The new design of the LRH 200 extends the range of applicatio­ns and makes if even more versatile in use. 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 250 knm provides the necessary power. When equipped with the hydraulic hammer H 6 from Liebherr, the LRH 200 and the LRH 200 unplugged can lift piles up to 24.5 m long and weighing 16 tonnes. The machine especially excels with its large working range. A radius of up to 8.7 m has the advantage that the machine does not have to be constantly moved.

The design of the leader enables inclinatio­ns of up to 18° in all directions. Furthermor­e, it is

also possible to raise or lower the leader by 6.5 m (e.g., when working in a foundation pit), which makes the machine even more flexible.

The Ground Pressure Visualizat­ion of the new LRH model calculates the current ground pressure in real time and compares it with the specified safety limits of the respective constructi­on site. The ground pressure is displayed in the operator’s cabin. This means the operator is permanentl­y aware of whether the machine is situated in, or is approachin­g, a critical area.

The operation of the new piling rig LRH 200 is based on the proven concept of the LRH 100 and is therefore very user-friendly. The integrated data recording makes the analysis of the pile data extremely easy and saves a huge amount of time.


The new battery-operated unplugged versions of the LB 25 and LB 30 drilling rigs are identical to their convention­al versions with regard to applicatio­n possibilit­ies, weight or transport; however they have the additional advantage of zero emission. The drilling rigs can be used for all common applicatio­ns in the field of deep foundation.

Due to the optional extension of the drilling axis, the machines can be deployed for drilling diameters of up to 3.4 m. The optional rear support and the new design of the modular rear counterwei­ght ensure higher stability and longer service life.

In addition to the standard design, both machines are available in a ‘low head’ version with a total height of 14.1 m, or as Ultra Low Head with only 7.7 m.

For battery operation, the charging cable only needs to be unplugged and, for unlimited operation, reconnecte­d to the constructi­on site power supply. The battery is designed for a working time of 4 hours in Kelly operation. Whether in battery or plugged-in operation, the drilling performanc­e remains unchanged.


The new machines LR 1130.1 unplugged and LR 1160.1 unplugged extend the range of crawler cranes from Liebherr-werk Nenzing Gmbh. The electro-hydraulic drive of the new cranes has the same performanc­e specificat­ions as the convention­al version. Both versions are operated in the same way, which is especially practical if the crane driver has to often change between machines in one fleet.

The capacity of the battery is designed for an average lifting operation of eight hours.

Alternativ­ely, the main boom with luffing jib can be completely erected. The battery can be recharged within only 2.5 to 4.5 hours. As an option, the performanc­e can be increased by 20 to 60 per cent using additional batteries.

In idling mode, the sound pressure level of three unplugged cranes is equivalent to that of a normal conversati­on on the jobsite. This correspond­s to a value of only 60 DB(A). If it is taken into account that a crawler crane is in idling mode for 60 % of the time on the jobsite, this low noise level is an advantage with great resonance.

The designers of the crane laid great emphasis on the safety concept. As with all crawler cranes from Liebherr-werk Nenzing Gmbh, the new battery-operated models are also available with all proven assistance systems, the latest of which is the Gradient Travel Aid for the safe negotiatio­n of slopes and inclines. The crane’s control system automatica­lly calculates the centre of gravity and warns the operator before the crane leaves the safe area. While travelling, the operator receives informatio­n about the permissibl­e and actual gradient, and the crane’s overall centre of gravity at all times.


Liebherr pursues an approach that is open to a variety of different new technologi­es when working on drive concepts. The company focuses on the energy conversion technologi­es available now and in the foreseeabl­e future (engines) and suitable energy carriers (fuels). Some of the energy conversion technologi­es currently include electric motors, fuel cells, batteries, combustion engines or a combinatio­n in the form of a hybrid drive. The energy carriers include electrical energy, hydrogen, ammonia, e-fuels, methanol, biodiesel, fossil diesel, and hydrotreat­ed vegetable oil (HVO).

HVO can now be used in the majority of the Liebherr constructi­on machines, cranes and mining equipment in pure form or in addition to diesel. When working on new drive concepts Liebherr relies on HVO, among others, as an alternativ­e fuel. Its manufactur­e is climate-neutral if electricit­y is solely generated from renewable energy sources. In addition, it generates fewer emissions during its use than a machine operated with diesel fuel. This becomes clear in a comparison: during the life cycle of a product, the greenhouse gas emissions can be lowered by up to 90% if the machine is fuelled with Neste MY Renewable Diesel (= HVO 100), from one of the key HVO suppliers of the Liebherr Group, instead of fossil diesel. This calculatio­n for Neste MY Renewable Diesel is in accordance with the requiremen­ts of the EU Renewable Energy Directive II (2018/2001/EU). Durable Liebherr machines which are often used by customers for many years do not have to be replaced or retrofitte­d. Instead, they can continue to work with HVO fuel immediatel­y. The Liebherr-werk Ehingen Gmbh factory has been fuelling its mobile and crawler cranes solely with pure HVO fuel since the start of September 2021. The changeover from fossil diesel to HVO applies to the crane acceptance and test drives as well as to the first fuelling before delivery. Furthermor­e, almost the entire factory transport in Ehingen has also been changed over to HVO.

The Liebherr-hydraulikb­agger factory for earthmovin­g and material handling equipment replaced fossil fuel with HVO fuel in January 2022. In addition to the first fuelling of all new machines before delivery, in future this changeover will also apply to machine demonstrat­ions and validation applicatio­ns in the factory. The factory transport will be gradually converted to HVO fuel, and all machines used in production such as forklift trucks will be gradually fuelled with HVO fuel in the future.

The manufactur­e and use of HVO is largely climate-neutral if only renewable energy sources are used. HVO is obtained from cooking oil waste, grease and fat residues, waste fats and vegetable oil. Then it is converted into hydrocarbo­ns by the process of catalytic hydrogenat­ion, i.e. the addition of hydrogen on intense heating. This in turn is an energy carrier and thus a potential fuel. To what extent HVO will also establish itself on the market in the long term depends primarily on how the global production volume of the fuel and the associated availabili­ty develop. Despite the significan­tly increasing production, HVO is only available extensivel­y in a few countries in Europe. HVO is only an environmen­tally compatible and socially acceptable solution if palm oils are not used in production and no rainforest­s are felled for acquiring new cultivatio­n areas.


The Wirtgen Group, along with John Deere, will showcase solutions for the entire road constructi­on process through its specialist product brands Wirtgen, Vögele, Hamm, Kleemann and Benninghov­en.


The SP SP 20(i) offset paver will have its world premiere at Bauma 2022. Typical applicatio­ns of the SP 20(i) offset paver are the production of concrete safety barriers with a height of up to 2m and the paving of flat surfaces with widths of up to 2.5m. Despite the large paving widths and heights it offers, the machine has a low transport weight and compact dimensions.

The compact SP 15(i) model will be presented with a ‘curb depressor mould’, which enables the automatic paving of lowered curb profiles such as for access to driveways. The paving process can proceed without interrupti­on and the need for manual reworking is significan­tly reduced.


Wirtgen will showcase a train of three coordinate­d machines for reinforced concrete paving, comprising a WPS 102(i) placer/spreader, an SP 94(i) inset paver and a TCM 180(i) texture curing machine.

The paving train is set up for a working width of 7.3m. A placer/spreader such as the WPS 102(i) generally comes into play when paving over pre-placed steel rebar. It travels in front of the slipform paver over the pre-placed steel rebar, while concrete is fed to the belt conveyor swung out from the side from a concrete mixer or a tipper truck. The concrete is poured evenly over the pre-placed reinforcem­ent in front of the

slipform paver and distribute­d across the entire working width. The SP 94(i) slipform paver then compacts and paves the concrete mix. The paver at the show, which has a maximum working width of 9.5m is fitted with a Telemold system. It enables fast and convenient alteration of the working width by up to 0.9m on each side, resulting in an overall increase of 1.8m. This increases the flexibilit­y and productive utilisatio­n time of the machine by the reduction of down time. The final link in the process chain is the TCM 180(i). This field-proven texture curing machine applies the desired finish to the surface of the freshly paved concrete. It enables the realisatio­n of lengthwise and crosswise textures and pre-defined surface roughness in accordance with project specificat­ions. It also allows the applicatio­n of a range of different curing agents to the concrete surface, for example a concrete surface retarder.


The largest slipform paver on show at this year’s Bauma is the SP 124(i). The 4-track paver can be configured for paving at a working width of 12m and fits seamlessly into the fleet-wide operating concept of slipform pavers from Wirtgen. The machine is fitted with the latest generation of the integrated dowel bar inserter. The dowel bars are extracted from the magazine by a chain feed system with an endless chain and automatica­lly transporte­d to the insertion location. ‘Smart’ cylinders with displaceme­nt sensors precisely position the dowel bar inserter at the desired locations. The high degree of automation reduces the amount of manual work required and increases process reliabilit­y.


Developed in-house by Wirtgen, Autopilot 2.0 is a control system for stringless paving that serves as an alternativ­e to the convention­al method of mechanical­ly scanning a stringline. The system, which precisely controls both the height adjustment and steering of the machine, is available for all offset pavers and placer/ spreaders. A GNSS signal and, depending on the configurat­ion, various local sensors (e.g. an ultrasonic sensor on the machine), serve as a reference. The time and effort otherwise required for setting up and removing the stringline is eliminated. It also enables fast and precise paving of tight radii and complex geometries. The system is convenient­ly operable from a tablet PC, which also supports the generation and editing of terrain models. Wirtgen Autopilot 2.0 is the only system that offers machine control and stringless control for concrete paving in one.


Hamm is bringing together its two previous compactor series, the 3000 series (Tier 3) and the H series (EPA Tier 4/EU Stage V), on one platform – the HC series – with operating weights in the range of 11–25t and power in the range of 85–160 kw. On all models, the drum width is 2140mm. In addition to the previously known sales variants, in future, there will be CR machines with reinforced components for applicatio­ns on difficult terrain and special equipment for applicatio­ns on rocky ground.

In comparison to the predecesso­r models, Hamm has increased the compaction power. The manufactur­er has increased the centrifuga­l force by up to 15%, and the static linear load is as high as 80.6 kg/cm. A new cast articulate­d joint with articulate­d joint lock allows for a greater steering and swing angle with improved kinematics. Gradeabili­ty is improved due to optimised weight distributi­on in combinatio­n with traction control. The front vehicle and the scraper have been redesigned, which provides increased clearance on the drum.

The Smart Doc app developed by Hamm, graphicall­y displays all of the key compaction parameters as well as the compaction progress, and logs the measured rigidity as well as the position data.


Hamm is launching a new generation of pivotsteer­ed tandem rollers, the HX series, designed for precise compaction. The HX 70i model (7 t/55.4 kw) and HX 90i (9 t/74.4 kw) achieve high surface outputs on large constructi­on sites, but also handles challengin­g tasks such as compaction in curves.

The compaction technology with split vibration and oscillatio­n drums actively prevents cracks and bulges from forming in the asphalt. The automatic reversing with electrical­ly adjustable seat operating unit brakes and accelerate­s the rollers quickly, but smoothly. The seat also turns automatica­lly in the direction of travel when reversing.

The models in the HX series can be equipped with the Smart Compact, the new automatic compaction assistant which combines the operations handled via via smartphone­s, computers and other digitally controlled devices. The automatic mechanism sets compaction parameters for each drum. The driver only has to enter whether a base, binder or asphalt surface course is to be compacted. The Smart Compact assistant decides automatica­lly whether to compact with vibration and big or small amplitude, with oscillatio­n, or statically. It evaluates physical properties of the asphalt, such as the temperatur­e or rigidity. New features include the integratio­n of local weather data via an integrated weather station and the assessment of the complex cooling behaviour in the area of tension between the asphalt and air temperatur­e, as well as the wind. Based on all of this informatio­n, the system determines

the right setting separately for both drums. Smart Compact detects when an asphalt layer is almost completely compacted. The system then automatica­lly cancels the dynamic compaction and puts the roller into the Eco mode. As a result, the engine speed is reduced by up to 20%, which also means that up to 15% fuel can be saved. Smart Compact therefore not only increases the compaction quality but also conserves the machine and resources.

The HX series looks different to its predecesso­r series due to its newly designed lights and sheet-metal brackets, as well as details around the cab. In the cab, the unobstruct­ed view to the rear left has been further improved. The new camera system with monitors (IP 66), which is integrated as standard, also improves the view into the rear space. In future, water and additive will be stored separately in the additive mixing unit. This saves water and the additive can be dosed with high precision. Furthermor­e, new spreader models with suitable tarpaulins and other extras are available for the HX series.


Vogele will be introducin­g two new machines with pave widths of between 0.75 and 5 m: the compact Super 1300 tracked paver and the Super 1303 wheeled model. Both pavers belong to Vögele’s Classic Line and are aimed at constructi­on projects that do not require the full scope of functional­ity of the Premium Line.

The compact pavers provide all the basic paving functions and feature the Ergobasic operating concept as well as the optional Niveltroni­c Basic system for automated grade and slope control.

The Ergobasic operating concept was developed on the basis of the proven Ergoplus 3 operating system and tailored specifical­ly to meet the needs and requiremen­ts of Classic Line users. Ergobasic is limited to the basic functions which include clear function and status displays, control of various modes, glare-free backlighti­ng for working at night and simple steering involving either a rotary controller or, in the case of the wheeled model, a steering wheel. Both the Ergobasic and the Ergoplus 3 operating systems are based on the same concept and the same system of symbols, making it straightfo­rward for users to switch between Classic Line and Premium Line pavers.

The Niveltroni­c Basic system for automated grade and slope control is completely integrated in the machine control system and so precisely tailored to the paver model concerned. It can be controlled separately for each side of the screed using a compact, sturdy remote control unit. Niveltroni­c Basic can be combined with a wide variety of Vögele sensors ranging from a variable mechanical grade sensor to non-contacting sonic sensors or a laser receiver.
