A leader in heli-logging innovation, Canadian Air-Crane has
stem harvesting," a revolutionary method of retention harvesting
that involves pulling standing tree stems up and out of the forest
with no damage to the tree or surrounding area.
"Standing stem harvesting" involves the Erickson
S-64 Aircrane using a hydraulic grapple with two shackles welded
to the frame allowing the grapple to be suspended horizontally.
The horizontal grapple grabs the stem where it stands as the
Aircrane snaps and pulls the tree off at the precut points. Unlike
helicopters, the Aircrane has the power and capacity to dead
lift the tree above the canopy and not drag it through the forest.
Standing stem harvesting opportunities have been identified
in the U.S. Pacific Northwest. This method has also been used
extensively on conventional helicopter timber harvesting operations across
