Arborist limb lowering device and method

An apparatus for the controlled lowering to the ground of a at least one severed upper portion of a tree using a first and second line in parallel, comprising an anchor having a first arrangement of guiding protuberances extending from a first side of said anchor in a first general direction, each said guiding protuberance including a bearing surface for frictional engagement with and redirection of a first line and a second arrangement of guiding protuberances extending from a second side of said second member in a second general direction opposite to said first general direction, each said guiding protuberance of said second arrangement including a bearing surface for frictional engagement with and redirection of a second line.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising:

• a. a mounting member attached to the tree;
• and
• b. a guiding member pivotally connected to said mounting member along a pivot axis such that said guiding member is pivotally moveable relative to said mounting member about said pivot axis for responding of the guiding member relative to the mounting member, said guiding member including a first arrangement of guiding protuberances generally extending to one side thereof, each guiding protuberance having a bearing surface for frictional engagement with the redirection of a line.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising

• an anchor having
• more than three guiding protuberances comprising two rows of guiding protuberances, each row including a plurality of guiding protuberances, adjacent guiding protuberances in each said row extending from said anchor in generally parallel relation to the other.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising

• an anchor having
• a first member secured in engagement with a lower portion of the tree against movement relative thereto, and a second member pivotally connected to said first member along a pivot axis and including thereon an arrangement of at least three guiding protuberances,
• wherein said second member if generally planar, and wherein said guiding protuberances perpendicularly extend from a first planar side of said second member, and further comprising guiding protuberances extending from a second planar side of said second member in substantial mirror image to said guiding protuberances extending from said first planar side of said second member.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising an anchor having an arrangement of at least three guiding protuberances, and further comprising an arm attached to and extending away from said anchor said arm including a distal end having a guiding surface for guidance of the line away from the anchor.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising an anchor having an arrangement of guiding protuberances, each said guiding protuberance including a bearing surface for frictional engagement with and redirection of a line about an axis of the guiding protuberance, a first guiding protuberance disposed in proximity to an intermediate guiding protuberance defining a segment of a path therebetween, and a second guiding protuberance disposed in proximity to said intermediate guiding protuberance defining another segment of the path therebetween without said segments crossing, the axis of said first, second, and intermediate guiding protuberance being generally non planar, wherein said arrangements comprises two rows of guiding protuberances, each row including a plurality of guiding protuberances, adjacent guiding protuberances in each said row extending from said anchor in generally parallel relation to the other.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising an anchor having an arrangement of guiding protuberances, each said guiding protuberance including a bearing surface for frictional engagement with and redirection of a line about an axis of the guiding protuberance, a first guiding protuberance disposed in proximity to an intermediate guiding protuberance defining a segment of a path therebetween, and a second guiding protuberance disposed in proximity to said intermediate guiding protuberances defining another segment of the path therebetween without said segments crossing, the axis of said first, second, and intermediate guiding protuberances being generally non planar, wherein said anchor comprises a first member for engagement with the lower portion of the tree and a second member pivotally connected to said first member and including thereon said guiding protuberances, wherein said second member is generally planar, and wherein said guiding protuberances extend from a first planar side of said second member, and further comprising guiding protuberances extending from a second planar side of said second member in substantial mirror image to said guiding protuberances extending from said first planar side of said second member.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising an anchor having an arrangement of guiding protuberances, each said guiding protuberance including a bearing surface for frictional engagement with and redirection of a line about an axis of the guiding protuberance, a first guiding protuberance disposed in proximity to an intermediate guiding protuberance defining a segment of a path therebetween, and a second guiding protuberance disposed in proximity to said intermediate guiding protuberance defining another segment of the path therebetween without said segments crossing, the axis of said first, second, and intermediate guiding protuberances being generally non planar, wherein said guiding protuberances comprise rollers and said anchor includes a winch for controlled rotation of said rollers.

An apparatus for the controlled lowering to the ground of a severed upper portion of a tree, comprising an anchor having an arrangement of guiding protuberances, each said guiding protuberance including a bearing surface for frictional engagement with and redirection of a line about an axis of the guiding protuberance, a first guiding protuberance disposed in proximity to an intermediate guiding protuberance defining a segment of a path therebetween, and a second guiding protuberance disposed in proximity to said intermediate guiding protuberance defining another segment of the path therebetween without said segments crossing, the axis of said first, second, and intermediate guiding protuberances being generally non planar, and further comprising an arm attached to and extending away from said anchor, said arm including a distal end having a guiding surface for guidance of the line away from the anchor.
