Crane tree removal in Washington and Oregon

When a crane is the safe option

Douglas fir reaches 80–200 ft at maturity (OSU Horticulture plant database), and a 1920s lot in Portland’s West Hills or on the slopes of Queen Anne and Magnolia in Seattle often has one standing closer to the house than the house is tall. Taking that tree apart by climbing means rigging every piece and lowering it through the canopy, over the roof, into a yard the size of a parking space.

A crane changes the geometry. The climber cuts a section, the crane lifts it straight up and swings it to a landing zone on the street, and nothing swings over the house. Four situations usually push a job to a crane:

• No drop zone. The tree is boxed in by the house, a neighbor’s house, a fence and overhead service lines.
• The trunk cannot be climbed. Dead or hollow trees are brittle; OSHA’s logging rule defines a standing dead tree as a “snag” and a “danger tree” as one that is a hazard from decay, root damage or lean (29 CFR 1910.266). See dead tree removal.
• Hillside lots. On a West Hills or Magnolia bluff the street is the only place a truck can park, so the crane reaches from the street over the house to the tree.
• Size. Anything in the “over 80 ft” bracket of our model, where a crane often costs less than the extra crew-hours of rigging. See large tree removal.

Rigging loads on a weak trunk are a known way climbers die. An OSHA hazard bulletin describes a climber roping down sections from the top of a large hickory who fell about 65 ft when the trunk snapped under the rigging forces; OSHA found that a preliminary examination of the tree would have shown it could not support those loads (OSHA Hazard Bulletin HB 3731, 2014). A crane carries each piece’s weight instead of the trunk, which is why decayed or dead conifers so often become crane jobs.

How a crane pick works

The crane sets up on the street or driveway on outriggers, and the operator and climber agree on a pick plan: how many sections, what each weighs, and where it lands. The federal crane rule, 29 CFR 1926 Subpart CC, sets the people requirements, and both states enforce it: Oregon OSHA adopted Subpart CC by reference as Division 3, Subdivision CC (effective June 2, 2021), and Washington carries the same rules in WAC 296-155 Part L.

• Certified operator. The employer must make sure each operator is certified or licensed through an accredited testing organization, a state license or an audited employer program (1926.1427; required since December 10, 2018).
• Qualified rigger. When a worker is inside the fall zone to hook, unhook or guide a load, the load must be rigged by a qualified rigger, and hooks need self-closing latches (1926.1425). On a tree job the climber is usually that rigger: the sling goes on, the cut is made, and the piece is already on the hook when it separates.
• Signal person. Required whenever the operator cannot see the point of operation, which is nearly always true when the load is in a tree crown behind a house (1926.1419). The signal person must be assessed and documented by a qualified evaluator (1926.1428; Washington’s version, WAC 296-155-53302, expires the qualification after five years).
• Nobody under the load. Only the people needed to receive a load may be in the fall zone when it lands (1926.1425).
• No riding the hook. Federal OSHA’s 2021 tree-care inspection guidance says the truck-crane rule bans hoisting a worker on the load or hook (29 CFR 1910.180(h)(3)(v)), even though the industry standard ANSI Z133-2017 §5.7.11 allows it. The climber normally gets into the tree by climbing or in an aerial lift; a crane-suspended personnel platform built to 29 CFR 1926.1431 is the fallback when neither is safe.

Each pick is weighed against the crane’s load chart for that boom length and radius. A Mississippi State University Extension risk guide gives a rule of thumb for weight by diameter: a stem 16–30 in across weighs roughly 2–10 tons, and one over 30 in more than 10 tons (MSU Extension P3717, 2025). Big Douglas fir trunks fall in those classes, so crews cut shorter sections when the reach is long. Ask the crew how many picks they plan and whether the crane company or the tree service is supplying the rigger and signal person.

Street-use permits for parking a crane

A crane on a public street, in a parking lane or on a sidewalk needs a right-of-way permit from the city transportation bureau, and the lead time can be longer than the tree permit.

In both cities the crane company usually pulls the street permit and bills it through. Make sure the quote says who is responsible, because an unpermitted lane closure stops the job.

Power lines and cranes

Cranes have their own clearance rule, and it is twice the tree-worker rule. Before the first pick, the employer must check whether any part of the crane, load line or load could get within 20 ft of a power line at full radius. If it could, there are three options: have the utility de-energize and visibly ground the line, keep 20 ft with a spotter, alarm or range limiter, or use the voltage table, which still requires 10 ft for lines up to 50 kV, 15 ft to 200 kV and 20 ft to 350 kV (29 CFR 1926.1408; WAC 296-155-53408 is identical and adds that the utility must supply voltage information within two working days of a request).

The climber is covered by a different rule. Anyone who is not a qualified line-clearance tree trimmer must stay 10 ft from lines energized at 50 kV or less, plus 4 in per 10 kV above that in Oregon (OAR 437-002-0306) and plus 0.4 in per kV in Washington (WAC 296-24-960(6)). The practical fix for the house drop is a free temporary disconnect: Pacific Power, Puget Sound Energy, Clark Public Utilities and Avista all offer one; PSE asks for at least 5 business days’ notice and Avista at least 3. See tree removal near power lines and the utility guides.

What a crane day adds

At launch we have no quote samples, so these figures come from our published model: a three-person crew at $225 per crew-hour in Oregon and $210 in Washington, built on the BLS May 2025 mean wage for tree trimmers (a labor index: $35.04 in the Portland metro, $33.85 in the Seattle metro), plus a crane day of $1,500–$3,500 for the operator and mobilization. Modeled estimate, not quotes (method).

Modeled estimate, not quotes (method). Two things pull the crane number around: distance from the crane yard, and whether the job needs a bigger crane to reach over the house from the street. A crane often removes crew-hours from the bottom row, because the climber makes a handful of big cuts instead of dozens of small rigged ones. Compare the no-crane multipliers on the tree removal cost page: ×1.25 within 10 ft of a structure and ×1.3 with no truck access.

The tree permit still applies

Using a crane does not change the tree permit. In Portland, private trees 12 in in diameter and larger need a removal permit from Urban Forestry, with no application fee since July 1, 2025 and replanting required (PCC 11.40). In Seattle, SDCI regulates trees from 6 in DSH upward in four tiers, and any Tier 1–4 removal must be done by a registered tree service provider carrying $1M in general liability with the City as additional insured (SMC 25.11). City-by-city thresholds are in our Oregon tree removal permits and Washington tree removal permits guides. The crane only adds the street permit above.

Questions to ask before the crane arrives

• Who holds the street-use permit, and what is the permit number and date?
• Who is the certified operator, the qualified rigger and the signal person, and which company employs each?
• How will the climber get into the tree: climbing, an aerial lift, or a crane personnel platform? Riding the hook is not one of the options OSHA accepts.
• What is the plan for the service drop and any cable or phone line, and has the utility been notified?
• Is the crane company’s insurance separate from the tree service’s? Ask for both certificates.
• Is the business registered? Check the Oregon CCB or LCB license (Oregon lookup guide) or Washington L&I registration (Washington lookup guide). Oregon’s contractor definition expressly includes tree removal (ORS 701.005), and Washington lists tree removal among the specialties that require L&I registration (RCW 18.27.010).
