FORESTRY EXCAVATOR H

itachi Construction Machinery (Europe) has launched a new ZX135USL-7 forestry excavator designed for logging, log felling, loading and digging. Assembled at HCME’s factory in Amsterdam, The Netherlands, the excavator is equipped with a robust undercarriage and offers more ground clearance (560mm) than standard models.

The short rear swing radius of 1,490mm makes it ideal for working in compact environments, says Hitachi. Operating weight is rated at 15.9 to 16.9 tonnes, and maximum digging depth is 5,760mm.

The impressive fuel economy of the ZX135USL-7 forestry excavator means that it delivers up to 9% less fuel consumption than the previous model. This is achieved with the help of Hitachi’s HIOS V hydraulic system.

Fuel efficiency can be further controlled by using the new Eco gauge, clearly visible on the cab’s multifunctional 8-inch monitor.

For added versatility, the ZX135USL-7 forestry excavator has a reinforced arm with piping for breaker or crusher, quick-coupler, as well as assist piping. A front blade is also available. Life cycle costs are reduced with the new Stage 5-compliant, 74kW engine,

which does not require an SCR system. This eliminates the need for AdBlue, filter replacements and associated maintenance.

The state-of-the-art, ultra-spacious cab should make a pleasant working environment. One of the quietest in the industry, Hitachi says the ZX135USL-7’s cab reduces vibrations by 16% compared with that of the previous generation machine.

The latest cab also boasts a combined seat/ console that takes up less space. Extra safety features include a fixed laminated front window and OPG level 2 front guard, plus additional lights on the cab roof.

GREEN CHIP Danish manufacturer Green Chip has taken over the rights to a woodchipper concept from Silvatec Skovmaskiner and has put the machine into production. The Green Chip CH 838 is a self-propelled chipper designed for chipping directly in the cut rows in the forest stand. The machine is equipped with a Stage 5 emissions-compliant Mercedes diesel engine rated at 230kW. There’s also a Logmer US 6-7 crane and HSM Harvester cabin.

The chipper can take trees from 1 and 2 thinnings with a maximum diameter of 38cm. It has a 20m3 container with high tip up to 5m, and can tip directly into 40m3 containers. The working capacity of the chipper is up to 120m3 per hour, depending on tree size.

LIEBHERR LOGHANDLER Liebherr has revamped its L 580 LogHandler XPower, improving the lift arms and the associated grabbers developed for log handling. A model of this latest generation has now been in operation for six months at the family-owned company Rubner Holzindustrie in Rohrbach an der Lafnitz, Austria. The new features of the L 580 LogHandler XPower were first tested at Liebherr’s Bischofshofen plant over a period of several months.

The Liebherr special wheel loader was so convincing that Rubner Holzindustrie decided to buy it right away.

The new lift arms feature manipulation heights of up to 7m and a reach of almost 4m. Meanwhile, the 360-degree rotatable grabber with a capacity of up to 4m2 enables versatile and time-saving transportation from the storage location to the company’s own sawmill, says Liebherr.

APF 2024 Exhibitor bookings for APF 2024, the UK’s largest exhibition for the forestry, woodland, arboriculture, fencing, trees and timber sectors in the UK, are now open. The 2024 show will take place once again at Ragley Estate in Alcester, Warwickshire on September 19th to 21st.

In 2022, 320 exhibitors and over 23,000 visitors attended the event and the organisers hope to exceed that total in 2024. APF organisers say last year’s exhibitors have first refusal on their 2022 site provided they book and pay for their stand

by September 30th. The remaining sites will be made available to all new exhibitors from October 1st.

SATELLITE POSITIONING Komatsu’s new satellite positioning technology can be retrofitted to its forest equipment. Able to show a machine’s position to within just a few centimetres, the new system uses several satellite systems – including Galileo, the European GNSS system – to determine precise positions with precision reduced from several metres to a few centimetres.

As a result, operators can mark exact boundaries with a new ‘geofencing’ feature – a digital fence that is added when planning an area to mark out ground to be harvested from protected areas such as a neighbour’s trees, ancient monuments or charcoal pile remains. Eliminating the need to walk the forest and mark trees for felling, boundaries and specific trees can be marked digitally based on map data collected from drones or scanning.

In addition, the exact position of each felled log is available with greater precision – beneficial in the dark or when ground is covered with snow – making it easier to see the assortment found in each log pile or at the roadside.

SPECIALIST WACKER NEUSON

G

EM Plant Sales, a construction plant and equipment supplier based in Kent, has delivered a specialist Wacker Neuson wheeled excavator to The Upper Medway Internal Drainage Board. This customised EW65 will be involved in some pioneering works on watercourses this summer.

Typically, a large, tracked machine would be used to carry out such jobs, but the decision was taken to seek a more flexible tool for major excavator works, which led to the use of a wheeled excavator.

The requirement was for smaller profile machine, with large reach, and a double- jointed boom section, which while being more compact in size, did not compromise the ability to reach far sides of the banks.

In 2022, the Board’s Works Supervisor, John Davis, began speaking with GEM Plant Sales about what Wacker Neuson could offer. After several site visits to see both the larger wheeled offerings and the tracked variants, the 6.5-tonne EW65 wheeled excavator with a double boom, extended dipper, and additional Steelwrist omni-hitch was considered the best option.

After that, West Country attachment specialist Exac-One provided a tree shear and mulcher head. The tree sheer can cut up to 300mm and retain cuttings using a unique gripping arm. The mulcher head

features a fixed teeth drum that activates on the use of the rotational circuit, allowing for high impact debris and brash clearance and excellent control during minor tree grinding. Completing the order was a 2m Bradshaw type bucket from Flails Direct to allow for weed and reed clearance works to be carried out. Due to the system requirements of the bucket however, additional low flow circuits had to be installed, representing a technical challenge to the build as it required multiple settings, hook-ups, and limiters.

SLOPE MOWER

McConnel has unveiled the Robocut S300e, an allelectric, remote-control slope mower. Building upon the capabilities of the S300, the new S300e retains that model’s features, including 55-degree slope operation, a 150m range, and bi-directional cutting. However, with the integration of electric power, it now offers the same high-performance level while ensuring zero emissions and reduced noise.

The Robocut S300e is powered by two Vanguard 48V lithium batteries, providing a runtime of up to 4 hours for uninterrupted operation on a single charge.

Recharging the batteries typically takes around 8 hours.

For added convenience, a fast-charging option is available, reducing the charging time to just 4 hours.

The Robocut S300e has a new 1.1m rotary mulching deck that has been specifically designed for electric operation. The new machine enters production later this year, with delivery of new orders expected in early 2024.

FORESTRY TYRES

Global tyre manufacturer CEAT Specialty will debut a comprehensive range of forestry tyres at Agritechnica 2023 (November 12th to 18th). The CEAT Specialty Forestry tyre range will cover the two key segments: log skidder and forwarder harvester.

VIMEK UPDATES 870 FORWARDER Vimek, the Swedish manufacturer of light machines for forestry thinning, has revealed an updated version of its largest and most powerful forwarder. The 8-wheeled 870.2 receives an updated colour scheme, a larger load area (increased from 2.4m to 2.6m without affecting vehicle dimensions) with more flexible bank locations, plus three Cranab crane options. Power comes from a Cat C2.2 engine with 55kW of power.

hen building a timber harvesting operation with used equipment at its core, every effort must be taken at the evaluation stage to ensure that the potential for problems is minimised.

Guided by this philosophy, Irish harvesting contractor Sean Ryan of Sean Ryan Forestry believes that his choices when it comes to timber harvesters and replacement harvesting heads strike the right balance of affordability, reliability and performance.

From Sean’s base near Silvermines in North Tipperary, he has built a successful timber harvesting enterprise with vast experience attained through many years of

Sean Ryan diversified into timber harvesting back in 2012. working on afforestation and reforestation projects through his original plant hire venture, giving him valuable insight into the forest industry.

Sean began working in forestry in 1998 when he purchased his first excavator. His interest in such operations was fostered by his father Martin’s engagement in plant hire, with a high percentage of his work already coming from forestry operations.

Nevertheless, despite building a successful business around forestry ground preparation, Sean felt that a more secure future could be offered by diversifying into harvesting.

Pursuing harvesting interests led to the

purchase of a used Timberjack 1070D harvester with a 752 head, purchased privately from an Irish contractor who was in the process of upgrading in 2012. To minimise costs, it was decided to focus exclusively on harvesting, with the necessary extraction catered for by other owneroperators, currently fulfilled by County Galway-based Thomas Conroy.

Before putting his 1070D to work on its initial assignment, the machine underwent a thorough appraisal and any areas identified as needing attention were comprehensively addressed. Deciding from the outset on the importance of maintaining a manageable scale and FORESTRY MACHINERY AUTUMN 2023

been taken off a harvester after the customer decided he needed a larger model. This made the head more affordable and capable of delivering the performance you’d expect from a new harvesting head.”

This level of performance is a major endorsement of the Silvatec base units, which are powered by Mercedes-Benz 906 engines with a power rating of 205kW. Hydraulics are provided by Rexroth pumps, which yield 130 and 195 litres per minute of oil flow from the crane and head pumps, respectively. The machines utilise Loglift L220V parallel cranes, with later models offered with the improved performance Mesera 280 variant.

“These two machines are from 2008 and 2009, and have worked 15,000 and 16,000 hours respectively, but they still have plenty of work left in them,” Sean explained. “The main components aren’t showing any signs of wear, and so far I have only replaced the fan belt in one and an oil cooler in the second machine. Apart from a few hose replacements and normal routine servicing, they just keep going. Some of the machines had reinforcement of the centre section, but these two are still original.”

Concentrating mainly on first and second thinnings, primarily for private forest owners, the machines are the ideal solution for these harvesting applications and still possess the operational capability to engage in clearfelling operations when required.

Nevertheless, for an owner-operator running older machines, thinning represents a far more lucrative prospect without placing the machines under undue strain, as Sean believes. “Even though I have done some clear-felling, I have no interest in

“These machines are still capable of harvesting 50 cubic meters per day in first thinnings, which is as much as is possible with even a new harvester,” Sean added.

“With the reliability they provide, they have low running costs, which is all I can ask for, and overall I am very happy with them and hope they continue to deliver long into the future.”

JOB SELECTION Mercedes engine totally original despite 15K hours.

“THESE TWO MACHINES ARE FROM 2008 AND 2009, AND HAVE WORKED 15,000 AND 16,000 HOURS RESPECTIVELY”

L220V parallel crane has stood up well to the test of time.

Some Sleipners had centre joint issues but not this one.

Drawing its name from the Norse mythical eight-legged horse, which was the mount of Odin, the King of the Gods, Silvatec clearly saw the machine’s eight-wheeled design as one of its chief attributes. In contrast to the current offerings from competing forest machine manufacturers, the Sleipner would have been among a minority of 8-wheeled harvester choices at the time of its introduction in 2001 when it made its first appearance in an eye-catching pink livery at Elmia Wood.

Ultimately, production of the new machine commenced in 2003 and ran until 2012, with approximately 100 units produced. Of these machines, 20 were shipped to Russia between 2007 and 2008, with three of these remaining unsold, while one was ultimately returned to Denmark and reworked to meet European market standards.

As the successor to the 896 TH, the Sleipner took the Silvatec harvester concept forward by a number of significant steps, and while visually the large curved cabin with increased glass areas was the most obvious change, a host of other features made it a much-enhanced harvesting machine.

Offered in a number of distinct variants, Sleipner was available in Light, Standard, Mountaineer and Boss configurations, with each having specific appeal to different markets and working conditions.

However, the common denominator of all four versions was the engine, hydraulics, and crane, all of which were already very well proven. Machines sold in the UK and Ireland were of the Standard and Mountaineer configurations, with the latter units favoured because of their heavier hub assemblies and greater tractive power, which suited use on steeper terrain. Few, if any examples of the Sleipner Boss model made it to our shores. It used a hydraulic cylinder on each bogie, which pressed downward to maintain ground contact and apply the highest level of traction. The hydraulic cylinders locked completely when the machine was stationary, ensuring unrivalled stability.

complexity to the maintenance and servicing of Sleipner machines, making it more difficult to access comprehensive information and support.

THE SILVATEC SPIRIT

Seen as a premium harvesting base unit, the Sleipner had many positives, including its terrain friendliness, stability, sheer power and oil flow. When it comes to negatives, there were clearly few. The failure of the Silvatec heads to evolve made them somewhat outdated when contrasted with those of the competition at the time.

Nevertheless, new heads were in development but unfortunately did not make it to market on time to save the financially ailing manufacturer. In 2007, Silvatec was taken over by Russian owners

Concern Tractor Plants, and attempts to stabilise Silvatec’s financial woes continued.

A working alliance was struck up with Gremo, where the Sleipner was offered in Gremo livery and designated 1350H, with up to 10 such machines sold. Modifications to the electrics and hydraulics by Gremo made obtaining detailed information for subsequent troubleshooting and repairs of these variants challenging. This was further complicated by the later takeover of Gremo

by Ecolog. The changing ownership and partnerships in the industry added

Production of Sleipner-badged machines was not restricted to harvesters, with a forwarder model also offered and designated Sleipner 814 TF, available as early as 2012. Coinciding with the 30th anniversary of the establishment of Silvatec, the latest generation Sleipner 8324 TH prototype was presented in 2014. It furthered the initial variant by offering more power, a revised cooling system, and the addition of a rotating cabin function and a more powerful crane.

However, by then, Silvatec had come under acute financial strain and the machine did not reach completion before they ceased trading in 2016.

Ultimately, the machine was completed by Euromatics, which continues to offer spare parts and technical support for Silvatec machines. The company also ensures the Silvatec concept lives on through its commitment to bringing the latest generation 561 harvesting heads to the market. This product is now available, with the company run by Pol and Timmo Tuesen also working on the manufacture of a modern generation Sleipner scheduled for completion in autumn 2023.

SEIZING THE MOMENT Exploiting demand for estate maintenance, Alun Hughes soon found himself establishing ALH Forestry Limited and has recently added a high-performing Sany SY155U to his fleet, as Paul Argent reports IMAGES PAUL ARGENT

hilst working for a contractor in North Wales, Alun Hughes saw an opportunity to offer his services to landowners requiring estate maintenance, something his employer at the time didn’t do. The purchase of a used 8-tonne machine saw Alun undertake several jobs before taking the full-time leap into running his own company.

With the estate management work decreasing and an increase in jobs asking him to cater more in forestry works, Alun looked to replace the 8-tonne machine he was running with a small timber grab and upscale to a JS130 with a larger attachment.

Once this step was taken, there was no looking back and eventually ALH Forestry Limited was born.

Over the past six years, such has been the demand for his services that he now has a healthy regular client list and clients willing to wait for his services. “We started off looking to put the timber we were felling and handling in for logs or fencing, this has rapidly changed with a huge demand for biomass chips,” he commented. “This has now pushed us down the path into supplying large quantities of biomass chip almost exclusively for Jenkinsons, the largest dealer in the UK.”

CHALLENGE ACCEPTED

THIS HAS NOW PUSHED US DOWN THE PATH INTO SUPPLYING LARGE QUANTITIES OF BIOMASS CHIP”

Whilst many companies look for the easy-to-harvest timber, Alun and his team very rarely get any of these jobs. Instead, they concentrate on the more awkward projects that demand a little more skill, thinking on their feet for ultimately higher returns. With his 13-tonne machine starting to show its age, Alun looked to the market for an upgrade. “We wanted a larger, compact tail swing machine that will allow us easier access into some of the regular sites we work on,” he explained. “I looked at several makes but some dealers never even bothered coming back to me, and if they did, they quoted ridiculous lead times and eye-watering prices even for a base machine.

We weren’t asking for huge additions just proportional rollers on the joysticks and the hydraulic lines to allow us to use a grab or a tree shear.”

Visiting the Arb show in Warwickshire last year, Alun happened upon the Sany stand.

Looking at the SY155U on display, he enquired about a deal but was told he would have to speak to the Welsh dealer Fitzgerald Plant Services. A call to Fitzgerald put him in touch with Mid and North Wales Salesman David Rollinson who invited him up to the company’s new office in Corwen, just 20 minutes from Alun’s base near Denbigh. “I had the chance to try the machine out there and then, and found it to be a huge improvement over the old FORESTRY MACHINERY AUTUMN 2023 19

JS,” he confirmed. “It was specced as we wanted it and was available within a week or so. We looked at the components and they were the same or similar to what you find on almost any other machine of this size. What really impressed us was the structural warranty Sany gives you. We had total confidence in both the mechanicals and the build quality to sign on the dotted line.”

The SY155U is one of the latest additions to the growing Sany product range. With an operating weight close to 16.5 tonnes, it sits above many of its peers in weight, but also in its performance in the field. Powered by a tried and tested 4-cylinder Isuzu engine kicking out 105hp, and mated to a Kawasaki hydraulic system, Alun says the excavator has more than enough grunt for undertaking their excavation or tree handling operations.

The components, like any compact tail swing machine are squeezed into the curve upper structure and whilst access is OK, any daily checks are all carried out either from ground level, or via the touchscreen in the cab.

Alun’s machine was supplied with a dozer blade, an addition that he finds incredibly handy for keeping the machine planted in some of the poorer sites they work on. “We often work with a loth of wood or greenery under the tracks and whilst the weight increase over the last machine helps, having the blade just to dig into the ground stops the machine from sliding.”

Being able to hold them higher up the trunk makes the operation far safer for us,” he explained.

ON SITE

We caught up with Alun as he and his two-man saw team were undertaking clearance works for a regular client at their pheasant shoot. The small copse had been damaged in 2021 by Storm Arwen leaving several of the large poplars and oaks either on the ground, partly broken or worse still leaning into other trees. The ground

surrounding the trees also threw up tricky issues as it required flattening before the saws could enter.

Grabbing a felled tree with the Intermercato grab, Alun was able to bend over the cover plants enough to forge a path through the undergrowth. This allowed access to the trees earmarked for clearance and also revealed fallen timber which had been quickly covered by greenery and also revealed the overgrown drainage channels crossing the site.

With access gained and an area cleared to stock timber, Alun was able to start pulling the fallen timber into place allowing it to be assessed and cut into a variety of lengths depending on its final use. “We have some

reasonable timber in here, especially the oak that can be sawn instead of chipped,” he commented. “We’ll pile up the material and assess whether it’s worth bringing our chipper in or transporting the material back to the yard.”

The chipper in question shows Alun’s commitment to the job and the fact that if you are going to do something, do it right.

Alun has recently invested in a Heizohack chipper mounted on a Mercedes 6x6 truck.

A rare site across North Wales and Cheshire (the areas within which Alun and his team regularly operate), adding this huge production machine to the fleet has opened up massive opportunities for the company and now enables them to handle large FORESTRY MACHINERY AUTUMN 2023 21

THE SANY STAYS SOLID AT FULL STRETCH EVEN WITH A GRAB FULL OF A 4M-HIGH OAK TRUNK” diameter timber with ease. “We used a smaller chipper before, and this required the excavator to be loading it and therefore taking it off production. If we are on a large job, we now produce and chip at the same time, making the job quicker and more productive.”

Whilst handling timber on the ground is one thing, putting it there is another. Using the Intermercato grab to stabilise a tree whilst it is cut ensures there are no surprises for the team. On the softer ground, the Sany stays solid at full stretch even with a grab full of a 4m-high oak trunk. “We have been very impressed with the way the Sany handles some of the larger timber,” Alun pointed out. “It is very strong on the slew which helps us out massively when moving timber out of the undergrowth.”

trunk could be seen to have cracked vertically and could potentially have exploded when cut with devastating effect.

Alun and his team decided to push the tree back to its vertical position before putting in a wedge cut at its base. This allowed the Sany to push the tree over yet still resulted in it splitting uncontrollably, but now in total safety for the lads on the ground and Alun in the excavator.

Access to the cab is via a step conveniently located on the front idler wheel, both the 9D and the 12D models share the same cab.

This example of a 9D was configured with a steering wheel, which moves just a half of a turn left or right to provide smooth and accurate steering of the tracked undercarriage. A joystick steering system is available as an option.

At 6ft tall, I found the cab had plenty of legroom to reach the single throttle pedal.

Despite the engine being located just to the rear of the cab, the manufacturer claims that these dumpers have a significantly lower internal noise level than their nearest competitor. During my time in the cab, the Darlington-built, 6.7-litre Cummins engine was unobtrusive.

Although this example did not have the optional air suspension seat, the 9D provided a remarkably smooth ride across the ground. The cab itself is suspended, but it is the unique undercarriage, which features the largest diameter bogey wheels on the market, that must take most of the credit.

T

he UK’s waste wood market processed more than four million tonnes of wood in 2021, according to industry body the Wood Recyclers Association (WRA). The association’s annual statistics show that the amount of waste wood processed in the UK rose from 3.82 million tonnes in 2020 to 4.17 million tonnes in 2021, with the total amount of waste wood collected returning to pre-pandemic levels of 4.5 million tonnes.

While biomass continued to be the biggest user of waste wood in 2021, representing 61% of the total amount of waste wood processed, there was also a slight increase in the quantities of waste wood being repurposed through board manufacture.

One of the UK’s leading exponents of recycling waste wood back into a useable product is Austrian manufacturer Egger.

The company operates 20 plants in 10 countries across the globe and produces in

excess of 10.5 million cubic metres of board products on an annual basis, which is split between building materials, flooring, and furniture production. The company operates two production plants in the UK at Auchinleck, East Ayrshire and Hexham, Northumberland where raw and melamine faced chipboard is manufactured.

Whilst the material produced at both plants requires some virgin timber, a large portion of the material is produced using FORESTRY MACHINERY AUTUMN 2023

high-quality, graded timber taken from the waste industry. Reliance on a steady flow of correctly graded and suitable waste material led Egger to establish its own facilities under the Timberpak banner to receive, process and distribute material to both plants.

LONG-TERM PARTNER

Gavin Ball, Sales and Operations Manager for Timberpak in the North East and Yorkshire takes up the story. “As a recycling and reprocessing company, we have loader is used to manage the sourced the recycled material required for Egger UK’s chipboard “THE 19-TONNE L550 XPOWER REPLACES storage and loading of the chips. production for over 20 years.

The addition of the longer arms into a dry warehouse where a new and toe-tip bucket on the L550 allows the Liebherr L550 XPower wheeled material to be pushed into taller piles giving

32 AUTUMN 2023 FORESTRY MACHINERY

WASTE WOOD RECYCLING | LIEBHERR L550 more room for manoeuvre around the building.

The warehouse contains two large storge areas where material can be stockpiled in readiness for loading on the steady flow of walking floor trailers which frequent the site delivering raw materials.

Whilst the area when empty of material and machines seems to be a big space, this can easily diminish, especially with the new Liebherr running around.

The XPower design of the wheeled loader allows for a shorter rear overhang compared to many competitor’s machines. Combining the shorter overhang with the loader’s impressive traction and climbing ability, Paul says he is able to push material almost to the eaves with little effort.

“I thought the machine had a puncture the first time I heard the air blow out!” Paul laughed “It’s a brilliant idea and seems typical of Liebherr to think of something like that. It’s all about the details.” The loading shovel and others in the fleet have impressed the management team at Timberpak with their class leading fuel consumption, which averages between 10% and 20% lower than the competition.

EFFICIENT PERFORMANCE

LIGHT IT UP

During extremely dry periods, the material coming off the chipper’s conveyor can create a very dusty atmosphere within the shed. Timberpak has specified a full array of LED lighting to both the front and rear of the machine. The high-capacity lights easily cut through the dust in the shed and have been bolstered by several additional safety features including a reversing radar and proximity sensor system to alert Paul of any personnel within the shed when the machine is operating. “We take the safety of anyone working on our sites extremely seriously.” Gavin commented. “A rear-view camera and a separate Liebherr Skyview 360-degree camera system adds to the safety features on the loader.”

As with any machines working in such a dusty environment, the risk of fire is an issue the company doesn’t want to have to deal with, and to mitigate any potential risks the Liebherr not only has a reversable fan to blow any dust out of the cooling pack, but a substantial Ardent fire suppression system has also been installed.

Paul Smith has been operating wheeled loaders at the site for several years and said that the Liebherr is by far the nicest machine he has operated here.

“The cab is so quiet and comfortable, and so well laid out.

Everything just falls to hand. I’ve operated the L580 XPower on the yard and that is a phenomenal machine. The L550 is just a smaller version of it. The power delivery, ease of operating, everything about it is designed to make the driver’s life easier.”

One small but quite important addition that has really impressed Paul is the inclusion of a small camera mounted in the bottom of the quick coupler. The image is relayed to a separate screen inside the cab and is invaluable when loading the walking floor trailers allowing Paul to see inside the body at all times. An additional feature of the camera is the inclusion of a high-pressure air jet to blow dust away from the lens, allowing Paul to stay in the cab at all times.

Right inset: Paul Smith is very fond of these Liebherr XPower wheeled loaders.

Right: L550 XPower can tip loads of up to 8,300kg to 12,500kg.

Like the other Liebherr loaders and material handlers in the fleet, regular servicing and maintenance are carried out by the manufacturer, which suits the Timberpak team as they are informed prior to the machine reaching the service interval and are able to plan sufficient times into their schedule for Liebherr GB personnel to attend site. “Overall, we have been very happy with the products we are taking from Liebherr. We do have some small niggles and issues which are being ironed out, but we expect these as with any manufacturer’s products.”

Gavin commented.

O

ver the years, various approaches have been taken to the harvesting of small diameter material and clearance operations in forest management, with each having their own advantages and disadvantages.

Finnish company Jarkko set up his business Reformet Oy is one of with an excavator-mounted energy wood head. the latest manufacturers to develop an energy wood harvesting solution, and newly formed contracting operation TMI JJ Iivonen – run by owner operator Jarkko Iivonen – has put one of Reformet’s earliest production models into service.

Having worked as an operator before deciding to establish his own business, the potential to engage in wood energy harvesting, early forest management and small diameter material clearance appealed to Jarkko. With a new mechanical solution developed and tested in real life working conditions by Reformet, the ideal attachment to serve the new venture was presented by this innovative company.

BESPOKE BUILDS Unlike most other manufacturers, Reformet designs, builds and tests equipment for specific forest applications, initially in response to the company founder’s personal working requirements at forest level. When it came to developing the Risupeto head, Jani Karvanen created a number of working prototypes before Jarkko Iivonen put the production model into service.

The first prototypes appeared in 2017 and 2018, and these were mounted on a New Holland E200SR reduced-swing- radius excavator. Despite being quite effective, the concept needed further refinement; the second prototype received grant aid from the European Regional Development Fund and succeeded in bringing the idea forward by a number of important steps. The final version of the concept emerged soon after.

Deciding to base his new business around the use of one of the first Risupeto energy wood heads, Jarkko’s initial expectations of the unit have proven correct based on the level of work he has successfully completed, something which bodes well for the future of his venture.

Jarkko considers the range of material that the unit can harvest and accumulate as being one of its main advantages. In addition, achieving impressive work rates in smaller diameter dense material is one of

the unit’s specialities, as he emphasised.

“I have never seen a head work so well in such a wide range of material sizes. It really has a fast work rate even in smaller material, and since there is no placement on individual stem with the blades and infeed doing the whole task, I can concentrate more on moving the head and boom through the remaining trees.”

Thanks to its compact dimensions and range of movement provided by the SMP tilt-rotator, plus the hydraulically extending mid frame of the head, accessing smaller material in between remaining viable trees is eased considerably. As Jarkko and his Kobelco worked in a delayed first thinning of a Scotts Pine stand during the time of our visit, the round logs from the thinning action had been harvested by a timber harvester in advance, with Jarkko then commencing his contribution to the management of the stand.

Running along the edge of a main highway, the stand had become engulfed by smaller diameter birch and other species which had regenerated naturally. Advancing rapidly through the material, which presented a broad range of size classifications, the taller material was taken down in a multiple section approach that eased the process and also eliminated the possibility of damaging the crowns of the remaining trees.

GOOD FOUNDATIONS “An excavator base machine from 16 to 20 tonnes is recommended for this head, and with the skis fitted this Kobelco SK140SRLC-5 is ideal for use here, explained Jarkko. “It is not too large for manoeuvring through the forest, it can drive the head very well, and it is stable enough to work at the maximum amount of reach.”

Placing additional ballast on the machine is the obvious way to enhance stability, but the Reformet Undercarriage Skis are a novel solution. As well as adding additional weight low down in the machine’s structure, these skis make the undercarriage more forest friendly while reducing undercarriage wear. Elsewhere, the host machine remains very much original with the exception of some steel frame guarding to the kick-out glass coupled with additional lighting for work in dense stands.

After six months deploying the new Risupeto energy wood head, Jarkko is incredibly positive about the product with it living up to his expectations and then some. Reformet’s concept is a viable alternative to previous approaches and is thoroughly deserving of its ‘Risupeto’ name, which translates from Finnish as ‘bush/twig beast’.

ONE FOR ALL

For years, the market for mulchers has been in two distinct sectors – large, cabbed models, and smaller pedestrian machines. This has recently changed with the introduction of the TMU40 from Italian manufacturer C4 Meccanica, explains Paul Argent IMAGES PAUL ARGENT

38 AUTUMN 2023 FORESTRY MACHINERY

C4

Meccanica is no stranger to the forestry market, having already established a healthy line-up of brush cutters, shredders and mulchers designed for mounting on small agricultural tractors. The Italian company also produces a range of augers, sweeper collectors and a multi-tool system designed for use with an excavator. However, it is the company’s first foray into producing a compact tracked carrier for use with its attachments that caught the eye of experienced dealer Arbforest, based in South Wales.

Sean Reilly, Arbforest’s Managing Director, explained, “Our initial meetings with the

We caught up with Sean and his team as they were undertaking machine familiarisation works with a customer on a large country estate in the Midlands. The site had been left to grow wild for several years with small saplings, laurels, rhododendron, and other fast-growing plants gaining a foothold around the large established trees and immature trees.

“The site also contains several large fishing lakes and part of the project includes removing the overgrown material away from the track sides allowing for easier access, and also do the same to the banks around the lakes to allow for safer and easier access to the fishing stands. Our client was originally looking at a small tractor with a mulcher along with handwork for all of this project until we showed them the TMU40V.” The TMU40V is essentially a compact tracked tool carrier capable of carrying a variety of C4 Meccanica’s powered attachments, but what sets it apart from other machines is its ability to swap from being a ride-on machine to an even more compact radio-controlled machine within a couple of minutes.

TRACKED TOOL CARRIER | C4 MECCANICA TMU40

Left: Max flow on PTO is 55L/min.

Below: 1.3m wide and 2.6m long.

OUR CLIENT’S REMIT WAS TO REMOVE AS MUCH OF THE UNDERGROWTH AS POSSIBLE TO ALLOW THE SMALLER TREES TO FLOURISH The TMU40 is two machines in one.

With an operating weight of just under 2.1 tonnes without a tool, the tracked carrier is powered by a 40hp Yanmar 3-cylinder engine meeting Stage 5 emissions regulations and which is mounted inside the machine’s sturdy frame. Anyone who has used an oil-hungry attachment whilst trying to manoeuvre a machine will know that usually one of the functions dies away unless there is sufficient oil flow throughout the machine. C4 has addressed this potential issue by fitting four pumps into the hydraulic circuit. One solely controls the oil to the drive system, whilst the other three all deliver a constant flow of oil to the PTO drive and auxiliary system.

A set of heavy-duty rubber tracks sit on the high-drive undercarriage and allow the machine to travel at up to 11km/h, The undercarriage design allows the TMU40 to

work on slopes of 20 degrees with an operator, and at 55 degrees in radiocontrolled mode with its tracks extended out. The 55-degree working angle is only achievable thanks to the engine being set in the chassis at an angle and having been equipped with an extra large oil sump to stop engine starvation. A variable pitch and reversible cooling fan has been fitted to reduce fuel consumption and also ensure the cooling pack is regularly cleaned of fine particles to prevent overheating and potential fires.

As a radio-controlled machine, the TMU40 operator has a lightweight control unit with easily identifiable switches, a tough LCD screen and a pair of joysticks. This allows the operator to use the machine under low hanging branches of established trees or in situations were keeping people

away from potential harm is paramount.

With the collapsible canopy closed, the operator station is kept clear of damage too, and ultimately this reduces the height of the machine down to just under 1.5m.

Putting the fully tested and certified ROPS up reveals an ergonomic and safe operator station allowing the operator to sit above the mulcher head. The remotecontrol unit is then plugged into a dedicated docking station transferring its functions for the basic operation of the machine such as travelling and powering the head onto a set of integrated joysticks each side of the operator’s seat. From this raised position the operator can easily see the entire width of the tool, down to each side of the tracks and the entire working are ahead of them.

Firing up the little Yanmar engine from the remote-control unit, the TMU40 was first set to work under some of the lower hanging branches of an oak tree. Working steadily backwards and forwards, the vegetation surrounding the tree was quickly cleared away. This task was carried out further into the small copse as more and more vegetation disappeared very quickly, leaving a carpet of green waste covering the ground. Having the canopy closed and walking behind the machine allowed the operator to carve a clear path up to each established tree.

ACCESS ALL AREAS

Pulling the machine out of the copse and experiencing a slight weep from a loose hose allowed us to get a look at the heart of the TMU40. A simple pair of catches allows the entire operator station to be raised on hydraulic struts to reveal the hydraulic heart of the machine and the offending pipe. A simple task with a pair of spanners cured the situation before the machine was readied to undertake some work with the cab up. In total, it took just two minutes to raise the canopy and fix into position and relocate the remote-control unit into its docking station. The seat back was raised and the machine ready to be driven to the next phase of the project.

Using the TMU40 as a traditionally operated machine saw it quickly remove undergrowth including a short stretch of vegetation on a steep slope into a drainage ditch. Small unwanted trees were also shown the full force of the machine quickly succumbing to the TRF135 mulcher. Finally, the team put the TMU40 to work clearing the sides of an access track to the fishing lakes. Taking just a couple of minutes to clear over 30m of vegetation and leaving a considerable extra width of track open showed the ability of the machine.

At just 1.3m wide and 2.6m in length without the TFR mulching head, the machine can easily fit onto a small plant trailer allowing it to be moved from site-to-site with ease.

USING THE TMU40 AS A TRADITIONALLY OPERATED MACHINE SAW IT QUICKLY REMOVE UNDERGROWTH 1,350mm cutting width for the TRF135.

hen we think of leading self-propelled chipper producers, the choices are far from restricted to units of Scandinavian origin, with leading manufacturers also developing productive machine solutions in many other countries across Europe. As a premium ambassador for German wood energy equipment manufacture, Albach has become a recognised force in the industry with over 600 of its machines now in operation worldwide.

Displaying a high level of pride in its product, coupled with dedication to continued innovation and progression, the company draws its name from the surnames of the founders, Alzinger and Bachmaier, which were abbreviated and merged to form the Albach name. Since its formation, the company is now controlled by brothers Franz

“BETWEEN THE TWO FACILITIES, THE COMPANY EMPLOYS A TOTAL WORKFORCE OF 200” and Michael Bachmaier, and continues to be a privately owned family-run operation, which is driven by organic growth and a passion for continual product development.

Based in the Upper Bavarian Menning region, Albach Maschinenbau GmbH & Co KG has its headquarters in Menning, which is coincidentally the founder’s home village, and provides manufacturing facilities for its Fallbach truck-crane-based tree felling units, grapple saws, and other special products, coupled with laser cutting and fabrication of machine elements in specialist manufacturing halls.

In addition to the Menning facility, Albach also has its Langquaid manufacturing facility, which is the main centre for the assembly of its Diamant 2000 self-propelled chippers. Between the two facilities, the company employs a total workforce of 200 and has an annual

turnover of €80 million (around £70m).

Recognising the market potential for a dedicated self-propelled chipper, work on developing the first prototype began in 2004.

Based on a Mouse self-propelled beet loader, the machine was designated Giga Hack, and even though subsequent machines benefited from refinement of the initial design, the original prototype proved a success, and a bright future in the production of such machines beckoned, with the Albach company founded in 2006.

The more advanced Albach Silvator self-propelled chipper was introduced to the market in 2008. Interestingly, the original unit is still operational and has now worked in the region of 25,000 hours, demonstrating how these machines are very much a long-term operational solution. In all, 114 units of the Silvator were built, while the first export sales occurred during its production

run in 2009 and were directed to customers in Poland and Slovakia. However, this was just the start of even greater success for Albach, which was soon exporting to 15 countries.

CUSTOMER APPROVED Since these early machines, Albach has advanced considerably in its level of market acceptance as it continues to pursue new markets worldwide. However, it places a very high level of importance on the selection of local representation based on the significance of after-sales for sophisticated machines such as these. Currently, Albach machines are represented by dealers in up to 20 European countries, with machines also operational in the USA. There have also been some notable exceptions outside these areas, with a machine dispatched to a stud farm owner in Dubai for the production FORESTRY MACHINERY AUTUMN 2023

of bedding material for his prized bloodstock.

All production of the Diamant 2000 self-propelled chippers is conducted at the Langquaid facility, where a high level of efficiency in the manufacturing process prevails. Working in an assembly line production model, a machine is completed every two and a half days, with approximately five to six machines at various stages of production simultaneously.

Close-up of the right-hand console within easy reach of the operator.

Andreas Wackerl and Michael Söllner at test chipping site.

ON A ROLL The process begins with the mounting of the main driven axles on specialist stands, which are attached via the hubs. These are then mated with the main chassis, which is a single spine-type formation with the machine’s diesel storage tank incorporated inside the frame itself, demonstrating the design’s ability to make the best possible use of space on the machine.

From here, all major machine elements are added on a phased basis, with the machines moving to the next stage of production by lifting the entire unit through the intervention of the overhead gantry cranes. In this way, machines are assembled in bays located side by side, instead of an elongated production line running the full length of a factory, which makes the best use of available production capacity and factory floor space at Langquaid.

As machines at different stages of manufacture are encountered through the assembly area, a range of Albach-specific design traits are highlighted. These include the wiring looms running throughout the machines, which are all coded for ease of troubleshooting. In addition, the visit made

for a unique opportunity to view the formation of the Albach design of crucial areas such as the intake, which employs a continuous chain mechanism welded in-house by a welding robot. Nevertheless, the real benefits of the Albach design lie in the unique rotor design and the ability of the machine to produce a broad range of chip classifications while maintaining high output.

At the time of our visit, an Albach Diamant 2000 had just left the Langquaid manufacturing facility to undergo predelivery testing in a real-life working environment. Each new machine conducts a full day’s operation to show that it meets the highest standards of performance before reaching the customer. On completion of this period of operation, the machine returns to Langquaid and receives a thorough cleaning before addressing any elements that were identified as requiring fine-tuning during the working trial.

TESTING Already on site and actively producing woodchip, the new Diamant 2000 was clearly finding its rhythm in its initial working role, with Michael getting the most out of this powerhouse. Working on the chipping of both larger diameter logs and brash, together with smaller whole trees that had been stacked to air dry in advance, the material was owned by one of a catalogue of

clients for whom Albach carries out chipping as part of machine testing procedures.

The machine has been designed to be adaptable and can handle both large and small materials. It is considered a versatile chipping solution due to specific features that were designed with careful consideration. Equipped with an Epsilon S110F double extension crane with a working radius of 210 degrees, the crane mounting position is ideal in that it brings a large volume of material within the machine’s range from a single setup point.

To ensure ease of penetration of the dense stockpile of material, the machine was equipped with a Cranab CE280 grab in finger grapple configuration. While this configuration may be among the most commonly chosen options, the machine can also be specified with other grapples or a Penz crane. With the fold-out intake table incorporating a continuous chain structure coupled with innermost vertical feed augers that serve to usher smaller material and brash towards the chipper intake, the composition of the chipper mechanism is one of the machine’s important areas of dedicated Albach design.

With the chipper producing a consistent flow of material, the hydraulic accelerator’s efficiency becomes apparent as the chip flow is deftly accommodated and discharged via the discharge chute, which has a broad working range and rotates through 270 degrees, while having an impressive discharge height to cope with high-sided trailers when side filling. Delivering impressive output, Michael highlighted the operational possibilities, which centre on the production of 95 cubic metres in seven

minutes when chipping 4m to 5m-long logs and using a Generation 7 rotor with a 60mm chip cut length and a 120mm screen.

COMPLETE PACKAGE However, the machine is not just all about effectiveness in operation and offering the utmost in operator comfort, as service access has also received much attention to ensure it reaches the ultimate level of convenience. As Michael provides a guided walk-around appraisal of the machine, it is immediately clear it has been built with the end-user at the centre of every design decision.

Conducting some sharpening of the chipper blades, a side work platform is lowered to provide a stable footing to conduct the task.

As an added safety feature, a fold-out safety rail surrounds the operator as the task is ongoing, while hand tools can be stored in the right-side storage locker with adjacent power sockets. The theme of operator convenience continues to the main tool storage locker at the front of the machine, which employs a raising cover with integrated underside lighting, while all the tiered storage units slide out to provide ease of access in this comprehensive storage compartment.

On completion of operation, transitioning to the road travel formation is a fast and easy process, and merely calls for retraction of the intake table, returning the crane to its holding cradle, lowering of the discharge chute and cabin, which ensures readiness for departure within minutes.

On the road, the machine can achieve a maximum travel speed of 80kph, which ensures fast relocation between chipping sites. However, there are some exceptions to

Albach takes great pride in the proficiency and adaptability of its rotor design.

Employing a mechanical drive, the rotor is protected by a unique guarding system that is activated by a sensor detecting foreign objects making contact with the counterblade. This results in the rotor clutch and infeed being shut down in a fraction of a second before any damage can occur.

Other notable features of the Albach rotor concept are its adaptability to cater to a broad range of chip classifications. The machine is offered with flexible configuration options, which allows it to be easily tailored to deliver the desired chip specification. Albach offers two specific rotor types for the Diamant 2000. The Generation 6 rotor presents a choice of either six or 12 knives. With six knives, chips from 10 to 40mm can be produced with the variance possible to as little as 2mm increments through precision adjustment.

In contrast, the Generation 7 rotor produces chips from 15 to 60mm sizes.

Three knife variants can be facilitated by Generation 7 rotors, including blades with quick-change facilities, blades for cutting lengths up to 38mm, and blades allowing cutting lengths up to 60mm.

Many chip sizes can be produced by the Diamant. this high travel speed, which is reduced when utilising tractor thread pattern tires for greater off-road tractive capabilities. In addition to the main drive axles, the machine utilises up to two additional axles, which are raised for off-road travel and lowered to comply with necessary legal weight requirements during road travel to offset the machine’s weight, which is over 32,000kg.

n an age of social media and the barrage of content available on any electronic device, it may seem difficult to sell the idea of a new dedicated forestry equipment show to present all that is new in large-scale harvesting and extraction equipment.

However, the organisers of the Swedish Forestry Expo are undaunted by the influence of modern technology and still believe there is a place for a dedicated showcase to present the latest forestry innovations to true forestry professionals.

They had initially hoped to stage their inaugural event in 2021, but the effects of successive Covid lockdowns meant the event was postponed twice, awaiting a return to

normality. The plan finally came to fruition in June 2023, with the show spanning three days from June 1 to 3. It took place at the Solvalla Racetrack, located in the Stockholm suburb of Bromma, just a short distance from the Swedish capital’s centre.

Organised by MaskinLeverantörerna, the association of forest machine manufacturers, the event garnered support from all major forest machine producers. They adopted a united approach to hosting a dedicated event aimed at presenting their latest innovations and creating a meeting place for timber harvesting professionals. Despite the event not being set in a forest environment, it in no way detracted from the experience.

However, the 951XC represented much more than just the addition of revolutionary pendulum axle bogies to the rear. This model adopted a more compact format when compared to its 6-wheeled 951 counterpart.

Notably, the front section of the machine was shortened, reducing the distance between the crane base and front bogies. This design modification made the machine nimbler and opened up the possibility of using it in later thinning applications. The machine on display at Solvalla was equipped with a C164 harvesting head.

Also taking pride of place on the Komatsu stand was the Centipede tracked forwarder.

This concept machine has been the subject of extensive research and, thanks to its rubber tracked design, offers several advantages over wheeled forwarders, especially in extremely sensitive terrain and low weight-bearing sites. Its dedicated design

Konrad ensures that the tracks run smoothly on the forest floor and over obstacles without the unwelcome headache of derailment.

However, some may undoubtedly question the viability of this machine and find it difficult to envision its operational success on steeper or rocky sites, suggesting that its appeal may be limited and it could be restricted to serving niche applications if it ultimately enters production.

BRAND AMBITIONS

Another highlight of the Komatsu stand was the presentation of its complete harvesting head range, which now includes the full range of Log Max units branded in Komatsu livery. Despite being part of Komatsu Forest, Log Max also had its own stand, where the complete line of heads was on display, including the new 5000V model, which

offers improvements in various areas. These improvements include a revised saw box design with a more powerful saw motor, faster feeding thanks to new type feed motors, and a revised hydraulic plumbing layout for uninhibited oil flow. Updated length measuring capabilities are also a feature of the 5000V, with several elements contributing to this enhancement, including an improved measuring wheel cylinder design and contactless encoder technology. The head weighs 950kg and has a maximum felling diameter of 74cm.

Other interesting harvesting heads on display included the Tigercat 534, which were mounted on the company’s 1165 wheeled harvester base units. In the UK, Tigercat machines are most commonly fitted with Log Max heads, so it’s intriguing to see the company’s own solution in action. The FORESTRY MACHINERY AUTUMN 2023 51

There are other makes and models available, but whatever the task, there is likely to be an excavator attachment to suit it.

APPROVED HYDRAULICS

Stockport-based Approved Hydraulics offers a wide range of excavator-mounted attachments to the forestry industry. This includes log grabs and Tiger Saw grapples from Intermercato, for whom Approved has been the UK agent for more than 10 years.

The company is expecting a major upgrade to Intermercato’s grabs later this year, as the manufacturer builds on the success of its

current TG range, with the launch of the GRX line.

Also available is a range of Tigergrip tree shears from Intermercato, alongside the PW and MW series shears from CMB. There are five PW models, to suit excavators with operating weights of 5-35 tonnes and they are particularly suitable for large collection in forest areas. The four-model MW line-up, with oscillating chainsaw unit, is designed for machines of 10-28 tonnes. They are designed for tree felling and branch removal on slopes, riversides, swamp land, transport routes and rail projects.

Providing a one-stop approach for contractors, Approved Hydraulics offers two stump grinders from Hydra Part, along with a range of four in-house developed cone splitters, log crackers from CMB and MST, flails, mulchers and post drivers and the firm has recently developed its own rotating excavator log splitter attachment, the AH700MPL-X, designed to efficiently split logs lengthwise.

FIELD & FOREST MACHINERY

Broxburn-based Field & Forest Machinery deals with a wide range of manufacturers, to meet the needs of UK forestry contractors. The company has four GMT Total Tree Control grapple saws available, with operating

The company also has a range of five cone splitter models, for excavators from 2-14 tonnes. An optional timber grab can be supplied along with the splitting cone, with no requirement for an additional hydraulic line.

ROTOTILT

Whatever the attachment, excavator operators will be able to make better use with the addition of a tilt-rotator.

The display in the RC system has a new a touchscreen design that provides access to the SecureLock safety locking system with just two button presses.

The RC tilt-rotators use pressurecompensating hydraulics, so they don’t require as much energy from the carrier machine, increasing efficiency and cutting fuel consumption. Customers can also specify a fully automatic QuickChange coupler at the time of purchase, or install it later as a retrofit, as their requirements change.

There will be RC versions of both the Rototilt R4 and R8 tilt-rotators. The RC system, complete with RC joysticks, has been designed to suit excavators with operating weights ranging from 10-43 tonnes.

A large woodchipper efficiently transforms felled trees and branches into wood chips, aiding in waste reduction and recycling. The mobility of these machines allows access to remote areas, reducing labour-intensive tasks and minimising environmental disturbance. In forestry, where sustainability and efficiency are paramount, woodchippers streamline operations while minimising ecological impact. Here are three we spotted for a range of budgets…
