Storm-damaged trees leaning onto an overhead utility line at night
Tree Wire Calcs

Know which tree to cut first.

When trees come down on a wire, Arbor Force tells your crew which stems are exerting the most force on the line and which removal is the most imperative — in the seconds you actually have.

The scenario

Three trees on the wire, one crew, and no time to model it.

Emergency work punishes guesswork. Cut the wrong stem and the span takes more load, not less. Arbor Force replaces the argument at the tailgate with a ranked answer.

Storm callout

Multiple failures across one circuit, all at once.

Tangled span

Several trees loading a single conductor at different points.

Limited crew

One bucket, one ground team, and a utility waiting on you.

Pressure decisions

The cut order is made in minutes, in the dark, in weather.

Capabilities

A load calculator that thinks like a field arborist.

Force ranking

Every tree contacting the span gets an estimated load, sorted highest to lowest so the worst offender is unmistakable.

Removal order

The app flags the imperative cut and the sequence behind it, so releasing one stem doesn't dump load onto the next.

Built for the clock

Field inputs take seconds — lean angle, contact point, rough diameter. No desk work, no spreadsheets.

Works from the bucket

Thumb-sized targets, high-contrast display, readable in rain, headlamp light, and gloves.

Share with the crew

Send the ranked plan to the ground crew and the foreman so everyone is cutting the same job.

Utility-ready

Log the span, circuit, and pole reference so your notes match what the utility needs afterward.

How it works

Three inputs on site. One ranked answer.

01

Log the span

Drop the pole-to-pole span and add each tree making contact with the conductor.

02

Enter field measurements

Quick estimates — lean, contact height, stem size, root condition. Precision comes from ranking, not decimals.

03

Get the cut order

Arbor Force ranks the load and marks the imperative removal, with the rest sequenced behind it.

Who uses it

Crews who work under live spans.

  • Commercial arborists running storm and emergency callouts
  • Utility line clearance contractors on assigned circuits
  • Municipal and storm-response teams clearing roads and services

A second opinion, not a substitute

Arbor Force produces estimates from the inputs you provide. It is a decision-support tool for qualified crews — it does not replace on-site assessment, utility clearance procedure, or your judgment about an energized conductor. Treat every line as live.

Put a ranked cut order in every truck.
