Patented tree-trimming and -removal tools have helped Heli-Dunn expand operations to industries unaccustomed to helicopter capabilities.

Based in Medford, Oregon, Heli-Dunn is an all-purpose utility helicopter operator providing logging and forestry management services to a growing array of industries. The company specializes in all aspects of vegetation and fire management, utilities infrastructure reliability, construction, backcountry logistics, and precision longline services.

Commercial helicopter pilot Scott Dunn founded Heli-Dunn in 2004 after spending the better part of his career flying for the logging industry. During that time, he built considerable longline experience in extreme mountainous terrain, where he supported fire suppression, aerial ignition, heavy lifts, search-and-rescue, logistical support, and geospatial, oil exploration, and mining and gas missions. He uses all these skills at Heli-Dunn.

Medford’s Rogue Valley International Airport (KMFR) serves as Heli-Dunn’s operations base. From there, Dunn and his team provide not only experienced, highly trained professionals and the aircraft to tackle the jobs, but also the Heli-Saw and Heli-Feller, tools Dunn designed and patented to support specialized logging, forest management, and vegetation clearing. Perhaps the biggest benefit for customers: the tools have helped increase job safety.

Patented Safety Tools
Heli-Dunn’s Heli-Saw operates from a helicopter longline, trimming from the top of the tree down 150 ft. to reach branches not accessible from the ground. The hydraulic tool was designed to quickly and efficiently handle tree trimming for power-line rights-of-way and travel corridors, especially in mountainous and other inaccessible areas. Heli-Dunn markets the product as being able to do in a day what it takes ground crews weeks to accomplish.

Dunn also designed and patented the Heli-Feller and Heli-Feller TF. Both are designed to precisely remove trees near power lines or infrastructure in difficult or inaccessible terrain as well as in any area with high tree mortality, thus reducing risk to logging ground crews and climbers. Both tools grapple and cut a section of tree at a time, which allows the pilot to maneuver the cut section away to avoid power lines and other obstacles.

Overcoming Misperceptions about Helicopters
Heli-Dunn has created new opportunities for helicopters on projects where a helicopter wasn’t the client’s first consideration because of misconceptions and misunderstandings about the aircraft’s capabilities. Through careful, honest communication and detailed project outlines, Dunn has succeeded in expanding into industries beyond logging and forest management.

In addition to its headquarters in Medford, Heli-Dunn has locations in Placerville, California, and Lumberton, North Carolina.
