The Heli-Dunn Heli-Saw is an aerially applied saw used to side trim vegetation along power line right of ways or travel corridors. Ideal for both accessible and non-accessible terrain, a Heli-Saw operation can complete several miles of side trimming per day. Production will vary based upon vegetation type and field conditions. Vegetation that threatens reliability to infrastructure can be quickly and proficiently mitigated leading to significant reduction in project implementation time and cost savings. The Heli-Saw was developed with the harsh demands of equipment in mind when operating within the unforgiving conditions of our western forests. Hearty, large diameter trees line our utility right of ways and travel corridors that weave through steep and difficult terrain. The combination of the performance capability of the Astar 350 Helicopter and our Heli-Saw offers the safest and most productive ,cost effective option for side trimming available to several industries worldwide.

Heli-Dunn implemented a Heli-Saw Operation for Washington’s Tacoma Power in 2014. Many successes developed as Heli-Dunn
side trimmed several miles of vegetation that required maintenance along transmissions lines. Reduction of exposure to risk, expedited project implementation and cost savings were benefits of the use of the Heli-Dunn Heli-Saw. See the video below to learn more about the project.

PG&E Currents coverage of our Heli-Saw project in Sonoma County, California.
In December of 2020, Heli-Dunn completed 60 miles of side trimming with our Heli-Saw on the Northern California Coast. Much coordination and planning was completed prior to and during implementation. The Heli-Saw was utilized in heavy conifer, mitigating hazards that are not easily or cost effectively by ground crews.
