Tree climbing gear: saddles, ropes, lanyards, inspection and buying questions

Climbing gear holds a person in a tree. That makes it the most important equipment on the crew, and the one you never buy on price alone. This guide covers the main pieces and the habits that keep them safe.

What it is

Tree climbing gear is the set of life-support equipment that lets a climber go up a tree, move around it and work with both hands free. It is separate from rigging gear, which handles the weight of cut wood.

A climber should use only equipment made and rated for climbing. A rope from a hardware aisle is not climbing rope, and a rope made for rigging is not life-support gear.

This page is part of our equipment library. For the money side, see the equipment guide.

Types

Saddle (harness)

The seat and belt a climber wears. Padding, weight spread and attachment points vary. Comfort matters, because a climber who is in pain will take shortcuts.

Climbing line and friction hitch or device

The main rope that takes the climber up and lets them move in the canopy. It is paired with a hitch cord or a mechanical device to control the climb.

Work-positioning lanyard

A strap or rope that holds the climber in place while they cut. A second, separate tie-in point is a good habit, and a flip line lets the climber lean back.

Carabiners and connectors

Locking connectors link the parts of the system. They should be rated for climbing, close and lock fully, and be loaded along their strong axis.

Throw line and bag

A light line with a weighted bag, used to set the first rope in the tree from the ground. Aim away from people and power lines.

Climbing spurs (gaffs)

Spikes strapped to the boots. Usually for removals, not for trees that will stay, since they wound the bark. Keep them sharp and the straps sound.

Jobs it fits

Pruning a tree that will stay: rope-and-saddle climbing, with no spikes.
Removals: spurs may be used on the trunk, and a rope system for the canopy.
Rigging jobs: climbers work with the ground crew and the rigging gear.
Aerial rescue practice: the whole crew should know the plan before it is needed.
Storm work: damaged trees are not stable, so the climber needs a trained plan and often a different approach.

Inspection and safety basics

These are general points, not a full safety program. Your equipment maker, ANSI Z133 and OSHA set the real rules, and a trained person on your crew should own them. Read the job site safety guide and use the tailgate safety sheet before work.

Look at the whole tree before you climb: dead limbs, cracks, cavities, power lines, insects, weak unions. Ask if the tree is safe to climb at all.
Inspect every piece before every climb: look for cuts, glazing, fuzz, stiff spots, bent metal, cracks and rust. Take doubtful items out of use.
Keep a log of each rope and sling, with purchase date and any incident. Retire items when the maker says, or sooner if they fail the check.
Stay tied in. Keep two points of attachment when moving, and never rely on a single unchecked anchor.
Keep chainsaws and sharp tools away from ropes. Use rope guards and think about where the saw will go before you cut.
Set up a rescue plan before climbing, and make sure someone on the ground can use it. Train it.
Look up and stay clear of power lines. Only trained line-clearance workers go near energized lines.
Follow ANSI Z133 and the OSHA rules that apply to you. Take formal climbing training; a book is not enough.

What to ask a dealer

A good dealer answers plainly and puts it in writing. Take this list with you, and get at least two written quotes.

Is this item rated for tree climbing, and which standard does it meet?
What does the maker say about inspection and retirement?
How is it sold: single items or kits, and what is left out of the kit?
Can I try the saddle, loaded, before I buy?
Do you offer a training course or can you point me to one?
Where do I send gear for inspection or repair?

Not sure whether to buy or rent? Try the equipment buy versus rent tool with your own numbers.

Quick comparison

Item	What it does	Check before each climb
Saddle	Holds the climber	Stitching, buckles, attachment points
Climbing line	Main rope for movement	Core, sheath, ends, stiff spots
Lanyard	Positions the climber for cutting	Cuts, wear, hardware
Carabiner	Joins parts of the system	Gate closes, locks, no cracks
Throw line	Sets the first rope	Knots, weight bag, wear
Spurs	Climb a trunk to be removed	Gaffs sharp, straps sound

Common questions

What climbing gear does a new climber need?

At minimum a saddle, a climbing line, a lanyard, locking connectors, a helmet and boots, plus training. Do not buy by price alone, and learn from a qualified trainer.

How often should I replace a climbing rope?

There is no single answer. Follow the maker guidance and the condition after each inspection. Retire a rope after a fall, a chemical exposure, a saw cut or any damage.

Can I buy used climbing gear?

Be very careful. You do not know its history, and hidden damage is common. For life-support gear, new from a known source is the safer choice.

Are spurs bad for trees?

They wound the bark, so most pros avoid them on trees that will stay and use them on removals. Check what your local arborists and standards say.

Do I need a harness for a bucket truck?

Rules differ for aerial lifts. ANSI Z133 and OSHA cover fall protection in lifts. Ask your trainer and read the lift maker manual. See the bucket trucks page.

What is the difference between climbing and rigging rope?

Climbing rope is made to hold a person, with stretch and handling suited to that job. Rigging rope handles the load of cut wood and has different traits. Do not mix them.

How should I store my gear?

Clean, dry, out of sunlight, away from fuel, oil and chemicals, and loosely coiled or in a bag. Keep manuals with the gear.

Where can I get climbing training?

Look for ISA or TCIA courses, local community college programs and experienced trainers. Our careers pages explain the paths. Training is not optional.

This page is general information, not legal advice and not a safety manual. Follow the maker manual, ANSI Z133 (the US safety standard for arboricultural operations), the OSHA rules that apply to your work, and your own written safety plan. Prices vary a lot, so get written quotes.
