New oriented strand board production plant in Russia's Torzhok: wood logistics with SENNEBOGEN material handlers

Once a waste product of the plywood industry, oriented strand boards have become a product of unparalleled success. In the city of Torzhok, Russia, the company Modern Lumber Technologies (MLT) LLC started one of the largest oriented strand board production plants in the country, with an annual output of around 600,000 m³. And four SENNEBOGEN material handlers are in use in the log yard and production facility.

Oriented strand boards are used for structural paneling, interior wall and ceiling paneling, and sill plating. They are created by pressing strands arranged lengthwise and crosswise into boards under high pressure and temperature. Completed in June 2016, the entire system, started in 2014 by Dieffenbacher and HOLTEC next to an existing laminated veneer lumber machine, is one of the largest oriented strand board machines in the world. A total of four SENNEBOGEN material handlers are used there to handle wood.

Three pick & carry material handlers in the log yard

The lumber, which is delivered to the Taleon Terra plant by truck from the heavily wooded area around Torzhok, is unloaded and sorted in the log yard by three SENNEBOGEN 735s. The mobile machines, with 3.2 m² log grapples, then place logs on the feed table for the production facility. For those in charge at MLT, lead by Technical Director Vladimir Tsvetkov, the SENNEBOGEN material handlers are perfectly suited for this role: "Positive experience with our current SENNEBOGEN machines, high component quality and, not least, the reliability of the material handlers by SENNEBOGEN are what convinced us."

The 735's pick & carry concept gives the machine flexibility in the yard. It can unload an entire semitrailer in just four loads. The 360° slewing uppercarriage, with a range of 11 m, can load the double-chain barking line on the feed table from the side or from the end.

 

SENNEBOGEN electric material handler feeds chipper line

The actual production process starts inside the facility. HOLTEC GmbH & Co KG from Hellenthal, Germany provided an entire system, complete with a stationary SENNEBOGEN 835 electric material handler that feeds the chipper to produce the strands. The material handler is driven by a 160 kW electric motor and operates in shifts around the clock. The machine itself is positioned in an isolated cage above the chipper and feeds it with a 2.0 m² grapple.

From the elevated, spacious Mastercab cab, the operator has an ideal view of the stalls, and also controls the system. The barked trunks are first thawed by two conditioning channels in order to chip the frozen wood in winter with the best results. After this conditioning, the trunks are taken from both channels by the electric material handler and placed into the hoppers of the chipper as needed. The chipper itself turns the logs into strands approx. 0.6 mm thick, which are then sifted, dried and glued into boards up to 40 mm thick. The entire facility is designed for an annual production of 600,000 m³ and produces oriented strand boards up to 2,800 mm wide.

Once again, this product shows the successful collaboration between SENNEBOGEN and HOLTEC with the goal of offering customers the ideal solution for their individual challenges.

Together with KwintMadi, the SENNEBOGEN sales and service partner that looks after the machine, even routine servicing and the provision of spare parts are guaranteed.
