Large & Technical Tree Removals
Some trees demand more than a chainsaw and a rope. When massive size, tight access, or proximity to structures makes conventional removal impossible, our technical crew brings the expertise and heavy equipment to get it done safely.
Watch a Massive Willow Removal— Crane & Grapple Saw
Large technical removal isn't a marketing phrase — it's an engineering decision. When a tree's size, lean, condition, or surroundings rule out conventional climbing rigging, the work shifts to crane lifts and grapple-saw cuts engineered for the specific load and target environment. This video shows that decision in motion: a massive willow in active wind, our 40-ton boom truck and grapple-saw rig taking it down section by section without ground crew exposure.

This video documents the removal of a large mature willow on a Southern Wisconsin property during active wind conditions — the kind of removal that has to happen now, not when conditions are ideal, because the tree has reached the failure threshold and waiting introduces more risk than working through.
Willows are among the highest-failure-rate species in our service area. The wood is comparatively brittle, the root systems are shallow and run laterally rather than deep, and mature willows almost always develop co-dominant stems with included bark — the structural defect where two stems grow tightly together and the bark gets trapped between them rather than fusing into a strong union. Under wind load on saturated soil, included-bark co-dominant stems are the structural failure mode we see most across Rock and Dane counties.
The crew runs the work with the same crane-and-rigger setup we use for any large technical removal, but the lift plan accounts for the wind. Sections are sized smaller than nominal capacity to keep the load stable, slewing is timed against gusts, and the grapple saw handles the trunk reduction after the canopy comes off. Grapple-saw cuts are faster on a willow trunk than climbing rigging would be, and they remove the climber from a tree that doesn't have the structural integrity to support a climbing line safely.
Throughout the lift, the Certified Crane Operator and the lead arborist coordinate by radio and hand signal. The ground crew stays clear of every suspended load per ANSI Z133. After the trunk comes down, chip work begins on the brush and log handling proceeds on the cut sections. The property is cleaned to pre-work condition before the crew leaves.

Crane-Assisted Removal — the Engineering Decision in Motion
A second look at how a crane changes the job: each section sized against the load chart at its working radius, lifted clear of the target rather than rigged down through it, and placed in the drop zone with no ground crew under a suspended load. ANSI Z133 standards govern every lift.

This video shows our crew performing a crane-assisted tree removal — the method that defines large technical removal when a tree is too close to a structure, too large, or too compromised to take down by conventional climbing and rigging.
The decision to bring a crane is an engineering one, not a default. The lead ISA Certified Arborist evaluates the tree's size, lean, and structural condition, the targets in the work zone, and the access available for the boom truck. The crane's rated capacity at the working radius — the distance from the crane's center of rotation to the load — sets how each section must be sized. A pick that's safe at a short radius can be over-capacity farther out, so every lift is planned against the load chart before the saw runs.
On the lift, our Certified Crane Operator runs the crane while the rigger sets chokers and slings on the section being cut and the climber makes the rigging cut. The crane takes the weight, lifts the section clear of the roof, power line, or landscape below, and slews it to the drop zone where it's lowered and processed. No ground crew member is ever under a suspended load during cutting. Communication runs by radio and hand signal per ANSI Z133 standards.
What a short clip doesn't show is the planning behind it: outrigger placement on stable ground, ground-protection mats to spread the load, the rigging-point selection, and the sequence that unburdens the tree in a controlled order. The crane makes the work faster and far safer than rigging every section down through a climbing line — but only because the plan is set before the first cut.

When Standard Removal Is Not Enough
Large technical removals account for roughly 30% of the trees we take down. These require advanced planning, specialized equipment, and arborists trained in complex rigging and crane operations.
80+ Foot Heritage Trees
Century-old oaks, maples, and elms common throughout Janesville and Madison often grow to enormous sizes that exceed conventional climbing limits.
Backyard Trees with Zero Drop Zone
When a tree is surrounded by fences, pools, patios, and neighboring structures, every piece must be rigged and lowered with precision.
Trees Entwined with Utilities
Power lines running through a canopy require coordination with utility companies and piece-by-piece removal to avoid outages.
Structurally Compromised Giants
Trees with internal decay, codominant stems, or root plate failure are too dangerous to climb. Crane-assisted removal keeps our crew safe.
Multi-Stem & Wide-Canopy Trees
Silver maples and willows with massive lateral branches need multiple rigging points and engineered lowering sequences.
Hillside & Slope Removals
Trees on steep grades require specialized anchoring, directional felling, and sometimes excavation support for crane pad setup.
Our Technical Removal Methodology
Detailed Site Survey
We assess tree size, lean, decay, overhead utilities, underground services, and access. Drone surveys for canopy inspection are available on complex jobs.
Engineered Removal Plan
Our arborists design a cut-and-lift sequence specifying rigging points, crane positions, and landing zones. We coordinate with utility providers when needed.
Equipment Staging
Depending on the job, we deploy cranes (up to 100-ton capacity), aerial lifts, specialized chippers, and ground-protection matting to safeguard your property.
Section-by-Section Dismantling
Climbers work from the top down, attaching each section to the crane before cutting. The crane lifts pieces clear of structures and lowers them to the landing zone.
Cleanup & Restoration
We chip brush, haul logs, grind the stump, and repair any turf damage. The goal: your property looks better than before we arrived.

Large Tree Removal FAQs
Questions about our technical removal capabilities.
What makes a tree removal 'technical'?
A technical removal involves trees that cannot be felled conventionally due to proximity to homes, power lines, pools, or other obstacles. These jobs require advanced rigging, crane assistance, or precision climbing techniques to dismantle the tree in controlled sections.
What size trees can you remove?
We handle trees of any size, including massive 100+ foot oaks and elms common in Southern Wisconsin. Our crane can lift sections weighing several tons, and our rigging systems allow us to lower pieces with pinpoint accuracy in tight spaces.
How do you protect my property during a large removal?
We use plywood matting to protect lawns, rigging lines to control every piece, and crane-assisted lifting to move sections vertically rather than dropping them. Our arborists plan each cut and lift sequence in advance.
Do you have the right insurance for large removals?
Yes. Tree Wise Men LLC carries $2 million in general liability insurance and full workers compensation. We provide certificates of insurance to homeowners and commercial clients upon request.
