VK9000 Series (Heavy Duty)

VK9000 Series (Heavy Duty)

Following our previous VK5000 and VK8000 series, the brand new VK9000 series is the latest and most robust debarker we have developed. It has a number of improvements that make using and servicing the debarker easier and safer than ever before. The VK9000 series debarker is primarily designed for mills using medium and large size logs.

With our famous heavy-duty trim, the VK9000 series debarkers are designed for modern large-scale production with high-speed debarking by using extra strong components as our standard, such as drive gears and drive shafts. Also, the VK9000 series features an updated machine frame for easier maintenance and enhanced working ergonomics. The renewed feedroll power transmission and pressure system are designed with the latest innovations in hydraulics and control systems used in the industry causing less mechanical stress on the machine and wood.

The newly designed modular construction of VK9000 series offers great flexibility to start the investment process with lower capital expenditure and build up the debarker as needs grow. The first stage of investment can be a single rotor machine. The machine can be extended by adding a butt reducing rotor and/or a second debarking rotor when higher speeds or cleaner chips are needed (VK Combi concept).

Machine modernizations

Your debarking needs may change during the debarker’s life span and we want to support you with product improvements. We provide various modernization packages for nearly all debarker models, for example:

  • The old debarking rotor with hydraulic tool tensioning can be changed to a new rotor with pneumatic tensioning including tool pressure remote control and automatic tool opening.

  • The second debarking rotor can be added to a single-rotor machine, which allows a higher feed speed and better debarking result.
  • The machine can be retrofitted with a butt reducing rotor for handling butts. Butt reducing improves the debarking and sawing result by trimming the butt of the timber to ensure smooth operation.
  • The closed pressure system of the feedrolls can be converted into an active system. This improves the machine’s functionality in varying conditions and reduces log damage.

When inquiring about machine modernizations, please inform us of your debarker’s model/type, serial number, and year of manufacture so that we can serve you as quickly as possible.

E.g. Model VK5048HD, no. 345/2010: the machine’s type number can also be in the format 5000HD-480-6-450-RHP

40 years in debarker manufacturing

It was year 1980 as Jukka and Martti entered the Valon Kone’s main gate in Lohja, Finland for the first time. Jukka wanted to apply for a job at the company after hearing positive feedback about Valon Kone from his from acquaintances. Martti did not know much about Valon Kone but had come for a job interview. Jukka received a job as a packer and Martti was hired in as a welder. “I was lucky, as I made it to Valon Kone. Sometimes it is enough to be in the right place at a right time”, Martti says.

In 1980, Valon Kone was already strongly positioned in the woodworking industry as an international debarker supplier. The company exported heavily e.g., to the Soviet Union of that time. The volumes of the logs to be debarked in the sawmills were much less than experienced today and this affected the debarker size. So, small machines fit well into plywood boxes, as they were delivered in tens of containers from the Lohja train station to the customers in Eastern Europe. “At that time Valon Kone had a separate packing department for machines”, Jukka explains. “And, Bruno Valo, the founder of the company was involved in the business. Although the management was shifted mainly to his sons”, he adds.

Jukka’s and Martti’s tasks in the manufacturing have shifted during the last four decades and the working environment has changed in many positive ways including improved working methods. The company has invested in the manufacturing facilities and the production process has been automated. This all affects well-being at work. “In the earlier days, working in a workshop was much dirtier and heavier than it is today”, says Martti.

In the last forty years Valon Kone also has experienced ownership changes. Despite the owners or business cycles, the personnel have always been considered important at Valon Kone and there has been a continued focus to invest in the employees. Valon Kone has been considered as a reliable employer and has managed to avoid laying employees off as best as possible during slower periods. “In the Lohja area, Valon Kone has a reputation as a safe employer”, says Jukka. “During all these years I have been laid off only once and then only one week”, he adds.

Long careers are common at Valon Kone, even today. It is not uncommon for employees to have 15 plus years of employment with Valon Kone. So, why has Jukka and Martti stayed working for the same employer for four decades?

Both men highlighted that Valon Kone has a good work community. Both, existing and previous colleagues, and supervisors get a big thank you! “In the past, the company management was clearly higher in the hierarchy than other employees, but nowadays it is different”, says Jukka. “And the well-being at work is emphasized more today than earlier”, he adds. “Independent and free work, as well as interesting content of the work improve the satisfaction at workplace”, Martti says in the end.

If you are interested in the varying tasks in the factory in Lohja, Finland, please contact our manufacturing manager. We are glad to tell you more!
