  • Patent number: 10470381
    Abstract: An insulating felling grapple is used with an insulating utility vehicle. The utility worker stands on the ground near the worksite and remotely controls the insulating felling grapple and the utility vehicle to perform the task. In addition to other standard trimming and removal tasks, the insulating felling grapple is adapted to allow for the removal of energized vegetation material. In one method, the utility worker grasps the energized vegetation material, lifts or moves the energized vegetation material such that it is no longer energized, severs the non-energized vegetation material, and moves the severed vegetation material to a discard location. A boom assembly of the utility vehicle includes a primary insulation segment. The felling grapple includes a secondary insulation segment, as well as a grapple and a feller. The grapple has at least two tines for gripping the energized material. The feller is configured to sever the energized or nonenergized material.
