Tree trimming with a Helicopter!!

There's a cool operation at Siler City today - a helicopter crew has been hired by Progress Energy to trim the trees that are encroaching on their power lines south of Siler City.

Amazing that they can do this with a helicopter! Here is the crazy, scary looking blade that dangles under the helicopter on a long shaft. It's 10 saw blades - look to be about 2' in diameter. The box you see at the left houses a gasoline lawn-mower type engine that is controlled by the helicopter pilot via the long shaft.



This is a little hard to see, but here the pilot is lifting off - you can see the shaft is bending a little as he ascends.


He lifts off completely and just flies away to the work site. He cuts for an hour or so before coming back for fuel. After fueling, he just takes back off for another round.


There is also an Asplundh crew on the ground - dragging the brush away.


Also hard to see - but this is the helicopter in the distance - he was working just at the treeline - and lifted for a minute to reposition when I took this shot....

Isn't that wild? I remember when the new way to trim was a tractor with a bush-hag on an arm that could swing up and cut vertical. Progress. E

Amazing - and it certainly does sound 'dangerous'...
