Very robust mechanical felling wedge designed for ergonomic and vibration-free timber harvesting. Mechanically, the principle employed is as simple as it is functional: a gear lever multiplies the pressure from the hand lever so pressing a wedge between two steel plates via a rack drive. The tree in question is then raised slowly and finally felled. Achieved with a lifting force of 60 kN (6T) however for the user on the ratchet lever only 350 N required.
