  • Aerial tree harvesting apparatus
    Patent number: 6263932
    Abstract: An aerial tree harvesting apparatus includes a first body and a second body having co-axial bores defining a tree receiving opening. The first body is suspended from a hovering aerial craft. The second body is suspended by cables from the first body. Delimbing members are mounted on the second body about the tree receiving opening. The delimbing members sever limbs from the tree when the second body is lowered. A severing saw is movable from a rest position adjacent the tree receiving opening transversely across the tree receiving opening, thereby severing the trunk of the tree positioned in the tree receiving opening once the tree is delimbed. Arms are provided to hold a tree positioned within the tree receiving opening during transport.
