This very robust, mechanical felling wedge has been 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. This is achieved with a lifting force of 60 kN. However for the user on the ratchet lever only 350 N required. The lifting height is 5.5 cm. Length 44.5 cm. Width 15 cm. Height incl. handle 25 cm. Weight 9.9 kg.
