We’re never satisfied. We always want to improve.

n the first half of 2010, we’ve seen the first signs of a market recovery. And that’s very good news for everyone. We’re quite simply seeing that many contractors have more work, which results in more orders and increased production at the factory, although it may take a couple of years before business returns to pre-recession levels. We can also note that the upturn is global, though clearly the rate of recovery varies between regions. The markets in Sweden, the UK, and Brazil have been active and stable since the end of last year, and now we’re seeing signs of an upturn mostly in Germany, Finland, and Eastern Canada. The demand fueled by the recovery varies around the world. In more mature markets, such as Scandinavia, increased productivity is the priority, while in growing markets purpose-built machines and methods adapted to local conditions are in demand. We’ll continue to closely follow each set of unique circumstances and use our passion for technology to develop machines that fulfill forest contractors’ needs. We know the forest industry and we understand the demands placed on forest machine owners the world over. For us, offering the best machines is not enough – service and support are equally important in the quest the create profitability for our customers. We want to get involved and contribute. Together, for example, we can develop useful IT solu-

tions. FortraX, which is a great help with production reports, is an example that will see success. Access to local service and spare parts are important to all contractors. Unplanned downtime costs money. We know that. We’ve already improved our global spare parts logistics and we have a local presence in every market in order to quickly help solve any problems that arise. Something closely associated with service is quality. Our ambition now is to accelerate the work to continually improve the quality of our products. Any shortcomings in quality are to be documented more effectively and solutions implemented even more rapidly. We’re never satisfied. We always want to improve even more.

Just Forest No 1 â&#x20AC;˘ 2010

FOKUS FINLAND

New opportunities for thinning experts The recession, new export fees on Russian timber, and new opportunities to extract energy from timber. In a short space of time, the Finnish forest industry has seen great change. Change that opens new doors for forest contractors and forest machine manufacturers alike.

Facts: Finnish forests q Finland’s forestlands cover 22 milli-

on hectares. No less than 9 million hectares of this forestland comprises wetlands, of which about 5 million hectares are drained. In terms of land area, private individuals own 61 percent of the forestlands, the Finnish state owns 25 percent (with almost half of the state-owned forestlands classed as conservation areas), forest companies own 9 percent, and other stakeholders own 5 percent. Growth per year is 100 million cubic meters and the annual harvest is 55 million cubic meters.

n the space of a century, the age structure of Finland’s forests has moved from one extreme to another. In the wake of slash and burn cultivation, there were no forests of an age suitable for regeneration. Timber reserves were found in aging forests. Attempts were made to regenerate older forests while forest plantations expanded. Wetlands were used to produce trees, as were forested fields. In sixty years, forest growth almost doubled and the greatest harvest potential shifted from clearcutting to thinning. In Finland, more than 60 percent of the forests are owned by private individuals. Holdings are distributed among almost 450,000 small plots and almost a million Finns are, to some extent, involved in forest ownership. Owners of small plots are particularly cautious when it comes to silviculture, and this issue is very much on the agenda. One of the aims of the FinnMETKO 2010 trade fair is to inform small forest owners that harvesting technology is not an obstacle. With modern machines, even difficult plots can be thinned without damaging the forest. In Finland, timber is harvested at lower costs than in any other country, which is remarkable considering the circumstances: small plots, a large share of thinning, snow, and sub-zero temperatures. What’s more, half of Finland’s forests stand on peat ground. In Finland, contracting evolved into its current form at the end of the 1960s, when many farmers and forest workers took a bold step and acquired their first

forest machines. The industry has always had excess capacity, which has resulted in favorable harvesting costs. The forest companies and contractors are now reorganizing things. New regional companies are being established to assume responsibility for more than just harvesting. Finland has reached an agreement with the EU to generate 38 percent of its energy from renewable sources already in 2010. Since there are little opportunities to expand within hydropower, and considering the limited possibilities to use wind power, Finland must rely on its forests to reach this goal. Biofuel from the forest will serve as a fuel for combined heat and power plants, also known as CHP plants. The pulp industry’s waste liquor, bark, and sawdust will also be used for energy production. In conjunction with harvesting, branches, stumps, and small trees are collected to fuel power plants. In addition to this, the idea is to harvest large quantities of small wood fuel from young forests. Naturally, raw materials from the pulp industry will also be incinerated in conjunction with this. The forest industry has also warned that timber prices will climb uncontrollably. State grants are being used to kickstart forest biomass harvesting. The objective is very ambitious. Today, only about three million cubic meters of forest chips are produced in Finland; in ten years, this figure needs to be closer to fifteen million cubic meters.

FOKUS FINLAND Within the Finnish forest companies, regional contracting firms are increasingly responsible for harvesting, in terms of both the practicalities and the administration, though there’s no standard model. Instead, the volume of the assignment and the regional company’s available machines determine the best solution for the job.

you have to be thorough, as the volume per assignment is less than 40 cubic meters. I’d dare to say that a prerequisite for profitability when harvesting wood fuel is to place the small piles of pulpwood in the same pile as the wood fuel,” he explains. Naturally, the additional equipment that the new assortments require worries Pekka. ”In our companies, additional equipment for 10,000 euros means costs of at least 100,000 euros if the equipment is to be installed in all ten machine parks.” A visit to the forest underscores what Pekka says. We find ourselves on peat ground, the trees are small, and most of the forest has been thinned. The company Konepalvelu Luoma Ky has a Valmet 830 forwarding birch wood cut into three-meter lengths. In the distance, thinning the forest, is Pekves Oy’s first new Valmet 901TX, delivered a couple of months ago. Pekka Tastula’s nephew Vesa is working the day shift. ”There are still features I’ve yet to learn, but I’d never swap this thinning machine for anything else – it does a fantastic job,” says Vesa.

Wood fuel and thinner forests of increasing interest Thinning, harvesting thinner forests, and wood fuel are all of increasing interest to many contractors. The Valmet 901TX and the Valmet 840TX are experts that meet a growing need. From the very start, product development work on the TX series had a clear focus on developing machines to face the challenges of thinning. ”Forests present different challenges in different countries. This means that contrac-

Just Forest No 1 • 2010

tors need machines that are effective under local conditions. The TX concept fulfills this need,” says Tobias Ettemo, Product Manager at Komatsu Forest. The focus on the need for thinning and harvesting smaller trees resulted in efforts to introduce a new class of machine featuring, for example, a new bogie design with low ground pressure and high ground clearance, more powerful engines, and high hydraulic capacity. Added to this

mix are powerful cranes with long reaches and flexible harvesting heads with large diameter ranges – all important characteristics when thinning. Contractors face demanding requirements with regard to efficiency and profitability in thin forests, so it’s important that we offer them machines with the right characteristics for being efficient regardless of local conditions, and this is what the TX concept does.

Increasingly cleaner engines Diesel engines have become increasingly cleaner and, compared to a couple of decades ago, the difference in emissions is enormous. Moreover, new engines compliant with tougher emission restrictions (Tier 4 interim, or Stage IIIB, as they are also known) are on the way. These requirements, to be introduced in 2011, entail a reduction in nitric oxides (NOx) emissions of 85 percent and a 97 percent reduction in particulates compared to emissions prior to the introduction of the Stage I requirements in 1996.

Facts about diesel Diesel fuel is named after q

Rudolf Diesel, the German engineer who invented the diesel engine and needed a suitable fuel to power it. q Just like gasoline, diesel is made from hydrocarbons. Hydrocarbons are molecules comprised solely of hydrogen and carbon atoms. The difference between gasoline and diesel is that diesel molecules are much larger. Regular heating oil has roughly the same composition as diesel. About 45 percent of the q energy supplied to a diesel engine in the form of diesel fuel is transformed into kinetic energy (motion). The corresponding figure for gasoline engines is 30-35 percent. This efficiency is what makes diesel engines more suitable for heavy machines and enables diesel cars to consume about a third less fuel than their gasoline equivalents.

Just Forest No 1 • 2010

n terms of requirements on cleaner emissions from diesel engines, Europe and North America have made the most progress since the first requirements were introduced in the mid-1990s. In Europe, the requirements are named Stage while in North America they are named Tier. The requirements on diesel engine emissions first appeared in the 1990s with the requirement of a 30 percent reduction in NOx content and a 10 percent reduction in particulates in the emissions from diesel engines with a power output in excess of 130 kW. In Europe, the stages have been introduced at increasingly shorter intervals, with checkpoints for emission requirements in 1999, 2002, and 2006. The intervals will be even shorter up to the next checkpoint in 2011, with a possible final checkpoint in 2014. The 2014 requirements entail a 97 percent reduction in both NOx and particulate emissions compared to the situation in the mid-1990s. Even the 2011 requirements stipulate a maximum level of NOx emissions of 2 grams per kilowatt hour and of particulates of less than 0.02 grams per kilowatt hour. The increasingly tougher emission requirements also mean that newer machines produce far lower emissions than older machines. In other parts of the world, such as Russia, Brazil, and Australia, requirements are not yet as strict, but Tier 3/Stage IIIA will even be introduced in these countries no later than 2016. That same year, China and India will introduce Tier 4i/Stage IIIB. Tougher requirements place tougher demands on diesel engines, the most suitable engine type for heavy work. What is interesting about the diesel engine is that its efficiency actually causes the greatest environmental problems. In a diesel engine, the fuel is combusted much more efficiently than in a gasoline engine, with

almost no unburned fuel or carbon monoxide in the exhaust fumes. However, the lack of carbon monoxide and unburned fuel means there is nothing with which the nitric oxides can react, even if a catalytic converter is in place. Since combustion involves an excess of air, soot and large quantities of nitric oxides are formed. The effective combustion makes the diesel engine economic to run. The emissions from a diesel engine are carbon dioxide, sulfur oxides (a natural component of the oil, but which is relatively easy to isolate in modern refineries), various nitric oxides (NOx), and soot. In order to reduce emissions, everything from DNOx systems to catalytic converters and particle filters have been used. Today, particle filters absorb more than 99 percent of the particles formed during combustion. Around the new millennium, advanced and optimized electronic direct fuel injection surfaced. Moreover, today both Common Rail and variable turbo boosters are used to optimize combustion and increase power without increasing emissions. The major challenge is to find a balance between lower NOx emissions, engine power, and particle emissions, as there are direct correlations between all three. If NOx content is reduced, the number of particles to be handled by the filter increases. In turn, engine power decreases as combustion is less efficient when exhaust fumes must be returned to the engine. In truck engines, much progress has been made, with a range of solutions that attempt to solve this equation. However, transferring technologies used on the roads to forest machines is a complex issue, as these machines work under completely different conditions, at different engine speeds, and with different torque requirements.

International emission requirements 2016 Tier 3 / Stage IIIA Tier 4a / Stage IIIB Tier 4b / Stage IV

Greatly reduced emissions The chart shows how much nitric oxide and particulate emissions are reduced under the different emission requirements. Compared to unregulated machines, the extent of the steps taken to reduce emissions from forest machines becomes very apparent.

Here we see the emission requirements for off-road vehicles in 2016. These requirements apply to vehicles such as forest machines. Generally speaking, we can say that requirements are increasing throughout the world. Worth noting is that no international agreements on emissions apply in countries shown in white.

Growing interest in simulators Forest machine simulators are becoming increasingly important in optimizing operator training and the interest in advanced simulators is increasing steadily. Simulators are now used to train operators in many parts of the world.

or contractors and forest companies, it is important that operators are efficient and productive from their first day on the job. As such, it is important that new operators know what they are doing from the start. Unnecessary downtime and inefficient operation, whether by a new or experienced operator, quite simply costs money. For some time, Komatsu Forest has been involved in the development of simulator platforms for training vehicle operators. This work has been conducted together with the company Oryx Simulations, which is now the worldleading supplier of advanced simulators for operator training. The collaboration between Komatsu Forest

Just Forest No 1 • 2 010

and Oryx started back in 1999 as a spinoff from Umeå University. Common to all the simulators is the use of advanced calculation techniques to create simulations that can be used in the training of forest machine operators, heavy excavator operators, and harbor crane operators. In the future, surgeons may be added to the list. There are a number of different Valmet simulators, in fact, more than any other forest machine manufacturer can offer. The latest in the line of advanced Valmet simulators is based on Valmet’s MaxiXplorer control system, the most modern harvester system on the market. MaxiXplorer is found on new Valmet harvesters; however, in the simulator, you can

even test other machines, such as Valmet forwarders and heads. The simulator has a 46-inch LED-LCD display. More than one hundred Valmet simulators are now in use around the world. Customers are mostly forestry schools, large forest companies, universities, and research companies. One example is the Professionalnoye uchilischche 14 educational institute in the Khabarovsk region of eastern Russia, which trains about 300 specialists every year. The use of modern harvester, forwarder, and feller-buncher simulators benefits their training courses considerably. ”The Valmet simulators will help us train even more high-class specialists,” says Viktor Bobin, who heads the institute.

Many new forwarder features Continually improving our machines is important. As a consequence, our forwarders have many new features. ”Development moves fast, especially on the IT side of things, and customer needs are constantly changing,” says Per Annemalm, product manager for forwarders.

Some examples of Valmet simulators q Valmet 911.4 with or without the MaxiXplorer control system.

Valmet’s simulators are currently found in almost 20 countries spread over four continents. So far, most simulators have been sold in Finland and Brazil. In Brazil, simulators are often included in major deals for machines that also encompass service and training. With sometimes more than 100 operators working simultaneously, and with a high turnover of operators, it is quite simply more cost-effective for the major forest companies in Brazil to use simulators rather than regular machines to train personnel. The current recession has not had any impact on the interest in simulators. In fact, quite the opposite is true, as many have decided to invest in operator training during the recession.

ne of the new features of all Valmet forwarders is the new computer, the PC X20, which is now standard on all new forwarders. There are also two display sizes, 10-inch and 12-inch, and a new wireless ergonomic keyboard that stows away in a handy storage space in the cab. An additional slave display (optional) can be mounted in the forward portion of the cab to provide an overview of all machine functions. The new computer is without a doubt the most powerful forwarder computer offered on the market, despite its compact size. Another new feature is the MaxiForwarder 4.8 software suite, with completely new and unique machine status and production reports as an option. The new, modern production reports are compliant with the latest StanForD standard, the software is fully integrated with the lever panels on the armrests—as well as the scales—and generates PRL files via the market’s most user-friendly interface. The user defines how the production data is to be stored: by assortment, log pile, landing, or destination sawmill. If the production is to be split between several drop points along the roadside, the system can use the GPS antenna to automatically recognize these locations. Machine status reports for the forwar

ders are based on the TSG standard. In terms of functionality, the machine status reports are identical to those of MaxiXplorer for harvesters. Naturally, the user interface has been customized to forwarder specifics. Aside from DRF files, reports can also be produced as hard copies, PDF files, and Excel sheets, with the contractor able to further refine the information in the form of tables and charts. ”Our customers really appreciate the machine status reports offered by MaxiForwarder 4.8. It’s easy to use, it’s well structured, and it’s packed with all the statistics a contractor needs for following up operations,” says Per Annemalm. Another new feature is MaxiN, which is a new and easy-to-use GIS-based navigation program for all forwarders. A rearview camera is now standard on all forwarders sold in the EU. This is an important new operator-oriented feature and the result of the health and safety requirements of a new EU directive on machinery (2006/42/EC). A few other operator-oriented features now included on all forwarders are the platforms for the ladders over the left front wheel and the hydraulic tank. This makes it easier to enter and exit the machine and makes maintenance work easier.

Steep terrain demands smart technology

n many places around the world, large forest areas grow in steep and near-inaccessible terrain, making harvesting difficult. As a result, harvesting in steep terrain has long been an interesting area for technological developments. The Valmet 911 X3M, a tracked harvester with great climbing ability on steep slopes, is one of the existing special solutions for harvesting in steep terrain. Regular machines also need special solutions. One of the first winches for forwarders was developed in Germany about ten years ago, long before issues such as ground pressure and land erosion were up for discussion in the German forest industry. However, in order to fulfill the special demands of harvesting in steep terrain, a completely new winch for harvesters has been developed in Germany. This harvester winch can be quickly attached to either the front or the rear of the machine. What’s more, the winch is also compatible with several different harvesters. The compact design makes the winch easy to transport between sites simply by loading it on a trailer. In this way, a contractor can use the same winch for several machines working on a harvesting assignment. The new harvester winch has a friction hoist, which makes it possible to maintain the same traction regardless of the coiled length of cable. This is especially good as the cable is only subjected to the traction force actually required. This also enables slow starts on slopes, which is better for the forest f loor. Slipping is reduced when maneuvering the machine, helping maintain the logging roads on which the machine is driven back and forth. So, with the aid of a winch, you can harvest timber that other machines would be forced to leave standing due to poor weather conditions.

Just Forest No 1 • 2010

More smart technology for working on steep slopes The bogie lift is an optional feature. With a bogie lift, the front q bogie axles can be angled independent of one another. This system provides maximum traction, particularly in difficult terrain, as the bogies can be individually adapted to the obstacles faced. Moreover, the machine’s turning circle can be reduced if the front bogie is raised. The tiltable seat (optional), together with low noise levels in the cab, offer working conditions that reduce fatigue, even on long work shifts.

q In Germany, the first winches made specifically for forwarders were developed about ten years ago, and now a completely new winch for harvesters has been developed.

New function for steep terrain A crane tilt function is now available for the Valmet 860.4. This function facilitates forwarding in steep terrain.

imply put, we can say that the crane tilt function enables the slewing motor to rotate the crane, which it is actually designed to do, rather than to lift it. This enables the grapple to hold more and makes it easier to get at the timber. The crane tilt function for the Valmet 860.4 enables the crane pillar to be tilted backward, at a longitudinal tilt angle of 5° to 22°. This provides a substantial advantage, especially when operating in steep terrain, as the crane slewing motor gains considerably more power. This has several benefits. For one, you can quite simply collect more timber in the grapple, which increases production. Another advantage is that when thinning, it’s easier to reach timber stacked behind a tree. As you do not need to move the machine as much to get at the timber, you can save a great deal of time otherwise spent repositioning. The operator controls the integrated crane tilt function with a simple foot pedal. The new crane tilt function has a fully integrated design achieved by attaching a joint from the slewing house to a plate fitted to the rear frame. The construction is supported by two cylinders that regulate the tilt angle. The crane tilt function, which is available for the Valmet 860.4 with a CFR11 Combi, is integrated with the crane valve, while the hose routing is integrated with the crane hose bundle. The compact design ensures considerably greater reliability. The crane tilt function is an option on the Valmet 860.4.

Questions for...

Jürgen Munz

Head of Central European Sales at Komatsu Forest in Germany.

What’s the current market situation in Central Europe? ”Following last year’s financial crisis, which unfortunately also affected the forest machine industry, we’re now starting to see growing market demand once again. It began with used machines in the second half of 2009, and now we’re also seeing even stronger demand for new machines.”

New dealers in France and Latvia France Pialleport SA is a new Valmet dealer in France. Gerald Pialleport founded the company in 1982, and today it is managed by Eric Pialleport.

ialleport AS manufactures the famous Camox Skidder, which has been sold throughout Europe for many years. Eric Pialleport’s team comprises 19 people and, aside from service, spare parts, and machine training, they also sell Valmet

machines in eastern France. Pialleport collaborates with two service partners and this enables the company to offer French customers optimal service. Spare parts are shipped directly from the central depot in Sweden.

”We are proud to have found a dealer such as Pialleport AS that is well established in the forest industry, and with which we can further our business in the French market,” says Bernd Rauser, CEO of Komatsu Forest GmbH.

How do you think the market will develop this year? ”Businesses are still very cautious about new investments, but there’s a lot to indicate that the growth in demand for wood products we’re now seeing, especially in Central Europe, will continue, at least in the mid-term. Based on this, I expect sales in 2010 to be considerably greater than they were in 2009.”

What trend do you see in forest machines in the near future? ”The trend toward increasingly larger machines, which is usually prominent, has ceased for the time being. The focus has shifted to smaller and medium-size machines that offer good performance. One example is the new Valmet 840 TX. In the near future, developments will most certainly be toward better operator comfort, further improvements in hydraulic efficiency and electronic components, and better communication between the machine and external sites. Our new FortraX system is a good example of this trend.”

Latvia As of March 1, 2010, SIA Valtek is a new Valmet dealer in Latvia. The company was founded in 2003 and is headquartered near Riga. The company specializes in engine technology and forest technology.

he contact at the new dealership is Juris Narubins, who has many years of experience in the tractor industry. SIA Valtek offers maintenance and spare part services 24/7 at five locations in Latvia. The

service team comprises eight mechanics. Customers can get rapid assistance on site from one of the company’s well equipped service trucks. ”Thanks to SIA Valtek, we can offer our Latvian custo-

mers first class service in several locations, and from a single supplier. With the help of Juris Narubins and his team, we can offer an even faster response to customer needs,” explains Heikki Vilppo, regional manager for the Baltic States.

Challenging environments demand more than just tough machines. They demand good clothes as well. And now the Valmet summer collection is here.

Quality clothing

almet’s clothes collection is characterized by quality and function, and the clothing is designed for use both on and off the job. Working professionally in the forest puts demands on the quality of your clothing, though you’d also like to be able to use them outside work. To achieve this successfully, the clothes must not only be attractive, they also need smart functional solutions and carefully selected materials. This means, for example, that the fabric used is breathable, water-resistant, and made from materials and components of the highest quality. One important aspect of our designs is that the clothes can be used in a layered manner. The new summer collection expands on the fundamental ideas of

Just Forest No 1 • 2010

our popular winter collection, in terms of quality, function, and colors. The new summer collection includes, for example, a f leece jacket, a polo shirt, a t-shirt, trousers, and sunglasses. All our clothing has a distinct but discreet design that is easily recognized. Valmet’s clothes collection is completely unique as it is produced specially for Valmet, in terms of both quality and design. The clothes are available exclusively from Valmet dealers. Our suppliers are carefully chosen for their capability to produce high quality clothing meeting Valmet’s exacting standards. They are also required to follow the BSCI code of conduct, which guarantees good working conditions for employees.

jörn Ström runs B Ströms Skogstjänst AB, with six employees, four of whom operate machines. Assignments mostly entail thinning for private forest owners through the company Sydved AB, which purchases timber and standing forest timber. Björn’s operations are centered on the small town of Tibro, located between the large lakes Vänern and Vättern in southern Sweden. Effective service was the deciding factor when Björn decided to switch to Valmet machines. ”I’d given much thought to how important I rate good service and it became a deciding factor,” he explains. The closest service workshop is in the town of Mariestad, just 30 km away. ”I knew the service was good and the workshop is conveniently located,” he says. Valmet’s workshop in Mariestad is staffed by four

mechanics and a spare parts manager. Three service trucks enable most service to be carried out in the forest. ”They’re always ready and willing when I need help,” says Björn. Over the years, Jerry Karlsson has been the primary mechanic for service and maintenance on Björn’s machines. ”We try to assist the same customers. By documenting everything we do, when we do it, and after how many operating hours, it’s easy to check the service record,” Jerry explains. The knowledge held at the workshop and by the mechanics is of value in many ways. ”I know that they know my machines inside out. This means they can advise on preventative measures, and the machines are always well documented if I decide to trade them in,” says Björn. Both Björn and Jerry say that service almost

becomes a part of a forest machine company. The machines operate in two shifts, which means they operate about 14 hours a day. Every 500 hours, someone from the workshop visits to service the machines, such as to change the oil and filters, lubricate critical components, and inspect the hoses. ”About half of all the service I do is planned, although when you’re on site at the customer, you often end up doing other work, too,” says Jerry. ”It’s about providing personal service on site.” Jerry has most things in his service truck. When the customer calls to book a service, he takes the parts he needs, along with a range of other parts. ”I’ve actually built up a somewhat larger service truck in order to provide a little unplanned service when I’m already in the forest,” says Jerry. Jerry Karlsson has been servicing forest machines for more than ten years and is always keen to learn more. Something he’s learned a great deal

about in recent years is machine settings, which he considers an important complement to service and maintenance. ”I find it interesting. I usually help contractors set up their machines, whether they’ve bought them new or used. There’s a lot to gain from it,” says Jerry. Even Björn has had help from Jerry to fine-tune his machine settings. ”The settings and the skills of the operator are important factors for profitability,” concludes Björn. Björn has just decided to replace his Valmet 830.3 with a new Valmet 840TX. This is an investment Björn has considered carefully and one which he is certain he will profit from. So Jerry will help out here, too, with two days of calibration. ”Sure, the machines work well with the standard settings, but it pays to make operator-specific settings,” says Jerry.

Quality with Kaizen Continual improvement is a key aspect of all quality work and those who fail to continually improve their products soon lose market shares to the competition. Kaizen is a well established Japanese method to guarantee continual product improvement.

Just Forest No 1 • 2010

mprovement work on harvesting heads comprises longterm development work based on the ideas of the Kaizen concept. Kaizen is Japanese, with Kai meaning change and Zen meaning continual improvement. Since the world rapidly changes, so do customer needs. As such, it is important to continually develop products to meet new needs. The customer is always central in Kaizen, and the idea is to give the customer what they really want and need.

The Kaizen concept unites experience from the Japanese industry’s approach to quality with a thorough understanding of the demands of the forest and technical curiosity. Systematic work conducted in accordance with Kaizen guarantees continual improvements in quality. These continual improvements chiefly comprise all the small, seemingly insignificant improvements that together make for a better product. Once the products

have been launched, changes and refinements – both large and small – are regularly made to the products. Some are improvements that provide a certain model with specific characteristics, others are more general and improve the quality of all harvesting heads. Hundreds of such improvements have been made to all our harvesting heads. Here are a few of the many improvements we’ve made to our harvesting heads in recent times.

Advanced maintenance Logging is probably one of the industries where the expression ”time is money” is perfectly true – working in difficult terrain, in extreme climates, with demands for continual operation, and most often in remote, near-inaccessible locations.

Facts: Maintenance Maintenance is defined in standards as a q ombination of technical and administrative c measures, including monitoring, that aim to keep a machine fully functional or else to restore full functionality.

Large image: Fibria has an extensive service agreement with Komatsu Forest in Brazil. Edivaldo Gonçalves and Rafael Pierre from Komatsu Forest flanking Jorge Moro, Gilmar Murça, and Antonio Albergio from Fibria. At left: Edvaldes Amaral and Ézio Lopes from Cenibra together with Willian Andrade (center) from Komatsu Forest. Cenibra has a service agreement with Komatsu Forest. At right: A technician takes a closer look at a Valmet 370E harvesting head.

uch conditions are found in many places, but let us take the example of Brazil, which is a country with a large land area where logging is often undertaken in very demanding environments. The demands on the machines are extensive, in terms of both reliability and production capacity. In order to support and aid machine owners, Komatsu Forest in Brazil has a highly qualified technical organization, with field offices in strategic locations in many Brazilian states. Moreover, there are specialist teams that work solely with the maintenance contracts Komatsu Forest has with the three large international players in the paper and cellulose industry. Technical support starts as soon as the customer gets in touch by phone or radio. After describing the problem with the equipment, the operator is advised over the phone or radio, as in certain circumstances this is sufficient to resolve minor problems without any need to stop the machine or send a technician. If the fault is more complicated, the technicians use their specialist knowledge to determine the type of fault. The technician best qualified to resolve the problem is then assigned. In most cases, technical support is provided at the logging site. Technicians take the required tools, spare parts, and other equipment needed to perform the maintenance and repair work. In 95 percent of cases, the problem

is solved on site, without the need to move the machine. In 90 percent of cases, support is provided within 24 hours, and in all other cases, within 48 hours. Otherwise, the work is scheduled to fit in with the customer’s planned downtime, maintenance windows, or operating hours. Since unplanned downtime is expensive, preventative maintenance is important. This often means service and maintenance, which includes extensive preventative inspections. The preventative maintenance is focused on the most important machine components. After each inspection, a report is filled out recording wear on the machine. Moreover, oil samples taken from important machine components are sent to the lab for analysis. This enables parts to be replaced before they fail. Naturally, this increases the reliability and service life of the equipment. In Brazil, comprehensive maintenance contracts are not unusual. These contracts run for twelve years, with comprehensive services for planning and governing machine maintenance. This provides better economics and higher machine uptime, which means greater profits in mechanized logging. A complete field support organization is available under all service contracts. This service is available in shifts, adapted to the work schedule of each forest company, with a 24-hour callout ser vice that includes weekends and national holidays.

Chattanooga focuses on quality When the global forest industry was at its lowest during the recession, the merging of all forest operations in North America into Chattanooga Manufacturing Operation (CMO) was quickened. Now, all manufacturing is conducted ”The Komatsu Way”, using Komatsu’s global quality and manufacturing processes for tracked Valmet machines.

ifficult terrain and extreme climates are common conditions under which forest machines are to produce equally efficiently every day of the year. In order to meet such challenges, quality has always been a keyword, regardless of whether the concerned Valmet machine has been built in North America or Sweden. At the factory in Sweden, rubber-tired machines have been produced ”The Komatsu Way” since 2005. Now, when the manufacture of tracked Valmet machines has begun at Komatsu’s Chattanooga plant, a plant known for its first-class quality and efficient manufacturing, quality continues to be of the highest priority when doing things ”The Komatsu Way”. Chattanooga Manufacturing Operation boasts market-leading production processes, the latest technology, and first-class quality assurance systems. In the case of the manufacture of Valmet’s tracked machines, this means welding robots, ultrasonic testing, savings on inputs, and a supplier quality assurance program. ”This move has enabled us to make better use of Komatsu’s resources, as well as to build tracked forest machines more efficiently. The machines manufactured at the Shawano factory in Wisconsin were among the best on the market. However, we have the necessary resources to turn a very good forest machine into a truly world-

class product,” says Dennis Riddell, CEO of Chattanooga Manufacturing Operation. Chattanooga Manufacturing Operation has a production capacity of more than 2,000 construction machines per year. ”Construction machines as well as feller-bunchers and harvesters benefit from the CMO method,” Riddell continues. ”However, moving production and improving the quality of the tracked forest machines is not something that happens of its own accord.” ”It requires experience and staying power, and is part of the more long-term plan to become KES-compliant, which is Komatsu’s engineering standard.” Cory Hathorne, Head of CMO’s design department, is responsible for the implementation of the different stages in the continual process to upgrade the tracked forest machines to the KES standard. ”The process was begun already before production was moved here, and it’s still underway. In fact, it never ends,” he says. The KES process begins with a review of all systems and assembly processes and the establishment of the best work methods for each model. ”The difference is in the approach to quality,” says Hathorne. ”By this I mean that we have in place very systematic processes and procedures throughout the entire manufacturing process. For example, we make predefined checks on individual employees, assembly workers, and welders throughout

the production chain, right down to the last person to work on the machine. We’re very good at uncovering minor concerns before they become major problems.” Improvements have also been made on the design side, such as by documenting all forest machine components. ”As engineers, we work in a theoretical world,” says Hathorne. ”We need to define and check all components on the materials list in order to guarantee the manufacturing process. This comprises much of the work we’ve done on the technical side. I don’t actually perform quality inspections, rather I check the manufacturing process from a technical perspective, which helps improve overall quality. This is what we’ve focused on.” ”I know that much of what we’ve achieved so far is not apparent from the outside; not to our long-standing customers and not even to our own product experts,” he continues. The introduction of engineering standards and Komatsu’s quality program has, however, benefited the forest machines immensely. This is all part of the long-term plan to build machines that offer maximum productivity and reliability. ”This is what we’ve done and will continue to do as a company. Our customers will see that our quality assurance work and our reliability exceed those of all others,” Hathorne ends.

Biofuel a hot topic World demand for biofuel is increasing and there’s great interest in biofuel harvesting systems. One such system on the market that’s already widely used comprises a Valmet forwarder fitted with a LoadFlex Bio bunk, a brushwood grapple, a Combi boom, and ProTec hose routing. Another efficient system used in Sweden for harvesting thin timber for biofuel comprises a Valmet 901.4 equipped with a Valmet 350.1 and a multi-tree accumulator.

n the future, bioenergy will be of great importance in some parts of the world. Two such areas in Scandinavia are Sweden and Finland. Finland has long been at the forefront of bioenergy and will, following a government decision this past spring, intensify efforts in this area. With annual investments of EUR 340 million up until 2020, Finland is to fulfill EU requirements to increase its share of renewable energy to 28 percent before the established deadline. A full 55 percent of the increase in renewable energy is to come from timber. In Sweden in 2009, bioenergy represented a larger share of the country’s energy production than hydropower and nuclear power combined for the first time. In figures, bioenergy contributed 125 TWh while the other two energy sources contributed 114.2 TWh combined. The large difference was mainly due to several of Sweden’s nuclear power plants standing idle in 2009. Normally, hydropower and nuclear power contribute with about 65 TWh each. In a position paper, the World Bioenergy Association (WBA) has shown that the global potential for bioenergy production is sufficient to meet the world’s collective energy needs.

Potential bioenergy production, based on several scientific studies, is estimated to reach 1135-1548 EJ (ExaJoule) by the year 2050. At present, the world’s collective energy consumption stands at 490 EJ and could exceed 1000 EJ by 2050, according to calculations made by the International Energy Agency (IEA). In this bioenergy expansion, it’s natural to meet the growing demand by using products designed for the purpose. In 2009, Komatsu Forest moved much closer to more effective biofuel management with the launch of its LoadFlex Bio option. With LoadFlex Bio, you can load forest residue up to almost the maximum permitted load, despite the low density of such biomass products. The forest residue can also be piled high with retained stability. The solution is fully mechanical, simple, and reliable while also maintaining bunk f lexibility. What’s more, with its hydraulic heightadjustable supports, LoadFlex can be controlled directly from MaxiForwarder. This makes the loading and unloading of forest residue both fast and effective. When harvesting forest residue, a loader fitted with ProTec, Valmet’s internal hose routing solution, is a great advantage. A Pro-

Tec-equipped loader allows you to position the loader crossways over the load to keep it in place. Otherwise, the loader hosing may catch, risking hose breakage. When fitted with LoadFlex Bio, ProTec, the E28 or E36 brushwood grapple, and hydraulically maneuverable supports, any one of the Valmet 840.4, 860.4, and 890.3 provides a complete system for biofuel harvesting. Valmet’s forwarders are also often used by customers to carry other equipment for refining biofuel, such as chippers. A Valmet forwarder’s fast loader, cab ergonomics, and reliability make it perfect for carrying a chipper. With its excellent mobility, a forwarder makes an ideal mobile chipper, as you can chip harvesting waste in a clearing, by a log pile, or by the roadside. Moreover, today there’s an effective and reliable method for harvesting biomass and small timber for use as biofuel. The Valmet 350.1, with its multi-tree accumulator, increases efficiency by enabling you to accumulate 3-4 trunks in the head. Since this function is also partly automated, the operator can focus on harvesting as usual. Specially developed software found in MaxiXplorer can also calculate volumes both accurately and rapidly.

Lego construction This replica of a Valmet 445EXL is built entirely from Lego using only a photo as a blueprint. It’s found on a website for Lego constructions, took two days to build, and was remodeled three times to ensure perfection.

Exciting It’s not every day a little guy gets the chance to see a harvester at work this close up. But suddenly one day, Hugo Svensson from Älmhult, Sweden saw a Valmet harvester clearing forest just outside his kitchen window. Now that’s exciting!

A great combination Contractor Magnus Eriksson has worked in the forest for 20 years , using Valmets for the past 15. And his Valmet 901.3 certainly is a fine example.
