Lightning Protection System Installation: Attatching the Cable
Descriptive Transcript
Point of view from an NPS arborist high in the branches of a leafy oak tree in a national cemetery landscape. Multiple ropes of different colors are used to climb through the branches and descend the tree. On the way down the trunk, a pair of gloved hands nails metal fasteners into the tree, using a hammer to bend the top over a wire cable to hold it in place. It switches to fast motion mid-way through the descent. [no audio]
Description
Adam, the NPS arborist, navigates the tree on climbing ropes and equipment. Adam is attached to the tree in three ways. The red hook is an auxiliary attachment, serving as a work positioning aid.
As he descends, Adam using fasteners to attach the cable to the trunk at regular intervals. The fasteners are solid enough to withstand pounding, but malleable so they can be shaped with a hammer to hold the cable in place. The fasteners hold the cable away from the surface of the tree to protect the bark.
