Technical report forestry technology

The forestry engineering sector is experiencing dynamic development, with the challenges of the future increasingly lying in the fields of semi-autonomous and autonomous driving technology.

In hard-to-access forest areas or on steep terrain, the autonomous driving systems with state-of-the-art on-board hydraulics provide first-rate support for drivers.

tv has specialised in significantly increasing the service lives and temperature resistance of cutting-edge drive units and functional components in the field of forestry engineering, with its development of customer-specific seals and slide bushings. According to a statement from Managing Director Harald Nitzschke, ttv is also offering drawing-based production parts from CNC processing in any defined quality.

Entire market in slight decline

According to surveys by the Kuratorium für Waldarbeit und Forsttechnik e.V. (German Center for Forest Work and Technology - KWF), 2016 saw a decline in the purchase of new machines in almost all machine classes in Germany, Austria and Switzerland.
In Germany, for example, around 9% fewer heavy machines were purchased for professional forestry applications than the previous year, and the same applied in the Austrian market, which suffered an even steeper decline.

The reasons for this are complex, and it appears that there is a trend for increased automation.

Maximum productivity is required

The requirements in the field of forestry engineering are clear: Increased productivity, more output increasingly intelligent solutions with assistance systems for the operators of forestry machinery. There is no magic solution here though, as it is also important to ensure a very good price-to-performance ratio in an extremely competitive world market.

Product diversity in forestry engineering

The variety of products used in forestry engineering is huge, and these range from harvesters, forwarders and combi-tractors right through to special forestry tractors.

This wide variety of products and the high strains put on the technology call for maximum quality and individual solutions, both from the machine manufacturers and from the suppliers of components and assemblies on the market. These high demands also mean that the number of engineers employed in agricultural and forestry engineering has almost doubled over the last 5 years, making it an increasingly interesting profession with excellent career opportunities, including the chance to work abroad.

ttv as a specialist for customer-specific solutions.

Over recent years, ttv has further established itself as a specialist in forestry engineering, with its two competence fields of seals and slide bushings. Typical challenges here include applications relating to drive trains, transmission gearing, ring gear seals and axles, as well as solutions relating to general production and assembly.

Standard products from stock are often not adequate in dealing with the enormous strains cause by mud, heat, cold, wood chips and soil, and this has lead ttv to the strategic decision to set up a separate development department for customer-specific product solutions, with substantial capacity to support all of its customers. ttv has an experienced team of specialists in the fields of technology and engineering working in this new area, and it attends to every conceivable detail of a project. Material properties, material composition and design make sure that dirt, wood chips and dust are kept strictly on the outside, and that the elasticity and functionality are retained even under extreme weather conditions.
