Helicopter Chainsaws

​​Vertical helicopter-mounted chainsaws, known as aerial saws, typically feature a series of circular saw blades mounted on a vertical shaft.​​ ​​

This assembly is often around 20 feet (approximately 6 meters) in length, allowing for efficient trimming of vegetation near power lines and other infrastructure.​​ ​​

The saw blades are powered by an engine, enabling precise cuts as the helicopter maneuvers along the desired path.​​ ​​​​
