The last few dry years have made it increasingly dangerous to fell trees with a hammer and wedge. Dead branches fall at the slightest impact. Forstreich, a company based in Freiburg, Germany, has therefore developed a radio-controlled, battery-driven felling wedge.
The forester places the wedge in the saw cut and starts the felling process, keeping a distance of at least ten metres. The design engineers use drylin W double rails and pillow blocks for the felling wedge's linear movements. They also use iglidur G plain bearings. The components allow the wedge to absorb radial forces over a long service life – even in environments with dirt, sand and wood chips.
Industry: Forestry
Customer requirement: Long service life despite dirt and high radial forces
