Safer lifting of trees.  Smooth lifting action, no shock from hitting wedges into cuts, less chance of falling debris.  Much less effort required than using a sledge hammer!  The gearing on these mechanical wedges makes this the easiest wedge I have ever used.  Any questions please contact me. 


The Koller Mechanical Wedge has been designed and manufactured by Koller Forsttechnik GmbH in Austria and is CE stamped and marked for identification purposes.
The mechanical wedge conforms to all relevant provisions of the Directive for Machinery (2006/42/EG) .

Two models available - For medium or large sized trees 
Low weight design for user benefit.

Special raised knobs on the spreader plate prevent the wedge from slipping out.

Mechanical Felling Wedge with Rack Ratchet Drive

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. 

  • Lifting force:  6T
  • Lifting height: 5.5 cm. 
  • Length 44.5 cm. 
  • Width 15 cm. 
  • Height incl. handle 25 cm. 
  • Weight 9.9 kg.
