- An aerial saw is a saw which is flown through the air. The aerial saw may also be known as a helicopter aerial saw. Large aerial saws are flown by helicopter to trim trees in remote locations when they overgrow power lines, pipelines or other infrastructure. A design used in the Appalachian region has ten circular saws on a twenty-foot shaft which is carried by an MD 500 helicopter, typically using a rigid boom of about 80 feet long on a gimbal mount, so that the saw can swing below the aircraft. The saw blades are powered by a 28-horsepower engine and the assembly weighs 830 pounds. This design is used to prune trees for customers such as American Electric Power. Another design, with a single, horizontal, 47-inch, circular saw blade, is used to cut the tops off trees which are at risk of falling across power lines. (en)
