INTERFORST 2018

•••6••• Messewelten Special show area: From seedling to squared timber At a circuit set up on a Interforst special show area covering some 1 600 square metres in the middle of exhibition hall B6, visitors are presented all stations that wood runs through “from the seedling to squared timber”. The first station deals with seeding and mulching and is presented by the Producer Com- munity for Quality Forest Plants of Southern Germa- ny (Erzeugergemeinschaft für Qualitätsforstpflanzen Süddeutschland – EZG). It is followed by the station of seedling and young stand care, where the German Statutory Accident Insurance (Deutsche Gesetzliche Unfallversicherung – DGUV), jointly with experts from the Laubau For- est Education Center (Forstliches Bildungszentrum Laubau) and the Board of Trustees for Forestry Work and Technology (Kuratorium für Waldarbeit und For- sttechnik – KWF) show how to use state-of-the-art accumulator technology in a safe way. The subse- quent stations deal with the opening up of forests and forest resource inventory using state-of-the-art drone technology UAS (Unmanned Aerial Systems). The efficient contribution made by state-of-the art forestry tractors will be explained, just like the ad- vantages for soil protection entailed by the use of a traction aid winches on the slope, or the benefits of the newly developed on-track forwarder – presented for the first time ever at Interforst 2018. Traction aid winches as real export hits One of the most signicant innovations in forest technology at Interforst – Special Show T raction aid winches constitute one of the most significant innovations in forest technology over the last ten years. As a valu- able tool used for forest work on slopes, they are indispensable for the protection of the soils and in terms of sustainability and under economic aspects. For companies from the German- speaking area, the winches have developed to become a real ex- port hit. Traction aid winches will therefore make a subject of dis- cussion at Interforst, both at the exhibitors’ booths and within the framework of the Special Show of the Board of Trustees for Forestry Work and Technology (KWF). Traction aid winches have been available since 2004. Initially, they were integrated into forwarders. Shortly afterwards, these first models were followed by versions for harvesters and for the logging of long pieces of timber. The most recently developed winches are put up on the slope separately from the machines. This makes them combinable with the most diverse forestry machines. The technology of these tools will be explained in the course of the KWF Special Show by demonstrat- ing such an autonomous traction aid winch on a KWF-tested sys- tem. In the Central European area, these winch systems are primarily intended to reduce wheel slippage and to improve the efficiency of power transmission. In addi- tion, they stabilize the machines also during jib movements on the slope. However, the machines may only be used on slope sites where vehicles can remain standing also without cable support. Besides their suitability for use on slopes, traction aid winches can also help overcome level pas- sageways over soils with a low load-bearing capacity and a high level of humidity without damag- es caused by slippage. The layout of the cable force is determined by the following factors: total mass of the machine, slope incli- nation and permissible slippage. Since traction aid winches were first launched onto the market, diverse versions have evolved. The classic integrated model of the traction aid winch consists of a winch integrated into a for- warder. The advantages of this system are its immediate readi- ness for use, for example. In ad- dition, all protection facilities for the driver can be installed direct- ly by the manufacturer, and the control of all systems is located in one place – complex interactions between several control systems do not have to be taken into ac- count. However, there are also disadvantages. For example, sufficient space for the system must be found in the supported machine. This leads to a reduction of the available load space. In addition, the emp- ty mass of the vehicle increases and its load capacity decreases – ground pressure increases. At the same time, the length of the cable that can be carried along is limited, and disengaging the ca- ble at the exit at the lower end of the aisle is not possible. The exhibitors of Interforst will offer an overview of the state of the art and the current developments in the innovative area of the traction aid winches.

Die Vollmechanisierung durch den Harvester thematisieren die Ver- anstalter dabei unter dem Aspekt der Arbeitssicherheit. An einem Harvester zeigen sie ausgesuchte Detailinformationen zur Maschi- nensicherheit. Kurz und prägnant werden hierbei technische Merk- male sichtbar gemacht, die das Arbeiten sicherer und komfortab- ler machen. Von den besonderen Kabinenscheiben bis hin zur Kli- ma- und Personen-Notsignal-An- lage können die Messebesucher die technische Sicherheit eines modernen Harvesters erkunden. An sechs Stationen werden die Motorsäge, die Sicherheitsfäll- technik, technische Fällhilfen, die Spillwinde, zeitgemäße persönli- che Schutzausrüstungen namhaf- ter Hersteller sowie der aktuelle Stand von Personen-Notsignal- Anlagen vorgestellt. Auf einer Gesundheitsstraße können sich Messebesucher durchchecken lassen. Geboten werden Seh- und Hörtest, Hautkrebs-Screening und BackCheck-Messungen. Die Pra- xisdemo „Seilwindenunterstütze Fällung“ demonstriert, dass das Abstandhalten eine Grundregel in der Forstprävention ist. Neben der Seileinbringung vom Boden aus werden die Schnitttechnik und der Verfahrensablauf realis- tisch nachvollziehbar gezeigt und Fachfragen kompetent beantwor- tet, heißt es. Zeitgemäße persönliche Schutzausrüstungen sind ein Schwer- punkt der Sonderschau. Foto: Messe München
