Wires and Trees Don't Mix!
Heli-Dunn offers the first and only patented aerial felling device with positive control and a 28" at cut height capability. The Heli-Feller is the safest and most productive combination within the industry. A major safety component incorporated in the Heli-Feller system is the 120' of rigid pole. Heli-Dunn developed this system to give the most margin of horizontal and vertical separation possible between the aircraft and the canopy (See below), significantly reducing the risk of rotor strike. We also have set the industry standard of the use of the rigid pole system in aerial felling. There is a significant safety concern and a greater risk to benefit introducing the four wire system into aerial felling.
