摘要:
A standing tree branch compression ring is adapted to be vertically raised about the trunk of the tree by lifting means. As the ring is lifted, the ring forcibly moves the tree branches inward. A plastic ring liner is affixed to the outer surface of the ring to reduce the coefficient of friction of the ring to mitigate tree branch damage. The ring includes a plurality of segments that form a generally toroidal shape and includes a releasable segment to accept the tree trunk from the side. The segment is then connected to the remainder of the ring, around the tree trunk, before the ring is raised.
