Storm triage

What is this tree doing to the conductor, the pole or whatever it lands on — and how urgent is it?

Tip: run a photo assessment first — with a measured scale anchor — and this screen opens pre-filled.

What are you asking?

How much force is this tree putting on the conductor?

Root plate intact, stem hinged at groundline, crown bearing on the conductor.

Recommended action

  • Treat the conductor as energized — assume contact is live.
  • Do not cut, rope or move this tree without utility coordination.
  • Establish an exclusion zone of at least 105 ft (32 m) around the base.
  • Contact the utility / system operator before any work begins.

Circuit & access

Single-phase tap or neighbourhood lateral.

Best estimate from the outage map or the circuit sheet

Bucket can set up on the shoulder.

Leave this if you could not get eyes on the access. It shows as unassigned on the commander roll-up.

Line crew + line-clearance crew

Energised conductor is loaded or entangled — a qualified line crew must clear or de-energise before tree work starts.

  • Crane or knuckleboomGreen weight ≈ 10,828 lbf — beyond safe tree-rigged removal.
  • Line crew standby (clear / ground the conductor)Tree is loading energised conductors — treat every part as energised.

Highest cut that gets the target under 400 lbf: about 42.3 ft up the stem.

  • Everything above the cut (7,677 lbf) comes off the load path. What is left applies about 248 lbf.
  • Hinged at the groundline: the residual 34 ft stem stays leaning at 15° after the cut.
  • Stem is roughly 14.3 in through at the cut, with the piece CG about 23 ft out from it.

Hypothetical only. It models tree mass and geometry — not hinge strength, conductor tension or hardware. Never cut on or near an energized conductor without utility coordination.

  • Side pull of 4,250 lbf square across the conductor — this is the component that racks crossarms, insulators and pole tops, and it is not resisted by span tension.
  • Estimate only: derived from photo geometry and published green densities. It models the tree, not the conductor — no span tension, sag or hardware rating is included.
  • High load on the conductor. Do not approach the contact point or the tree base without utility clearance.
