How to Climb with Tree Spikes (Essential Tips for Safe Woodwork)

Understanding the Basics of Tree Climbing with Spikes

Before we even think about strapping on those spikes, let’s lay the groundwork. Understanding the fundamentals of tree climbing will not only make you a better climber but a safer one.

What are Tree Spikes (Tree Climbing Spurs)?

Tree spikes, also known as tree climbing spurs or gaffs, are specialized pieces of equipment designed to provide temporary support and traction while ascending or descending a tree. They consist of a metal shank that attaches to the climber’s lower leg and a sharp, pointed spike (the gaff) that penetrates the bark and wood of the tree.

Think of them as temporary footholds that allow you to move vertically. However, unlike natural footholds, these are entirely dependent on the integrity of the spike and the wood it’s embedded in.

The Purpose of Using Tree Spikes

The primary purpose of using tree spikes is to enable climbers to efficiently and safely access specific areas of a tree for various tasks, including:

Tree Pruning: Removing dead, diseased, or damaged branches.
Tree Removal: Dismantling trees piece by piece in confined spaces.
Arborist Work: Performing inspections, treatments, and other maintenance tasks.
Lineman Work: Accessing and maintaining power lines that run through trees.

In my experience, tree spikes are invaluable for jobs where a bucket truck or other aerial lift equipment can’t reach. They allow you to navigate the tree’s structure with precision and control.

Why Safety is Paramount

I can’t stress this enough: tree climbing with spikes is inherently dangerous. According to the Tree Care Industry Association (TCIA), falls are a leading cause of injury and fatality in the tree care industry. The risks associated with using tree spikes include:

Gaff Outs: When the spike slips or pulls out of the wood, resulting in a sudden loss of support.
Limb Breakage: Stepping or leaning on a weak or dead limb that breaks under your weight.
Equipment Failure: Malfunctioning or improperly maintained equipment.
Environmental Hazards: Encountering bees, wasps, or other stinging insects, or being exposed to extreme weather conditions.
Electrical Hazards: Contacting power lines that run through or near the tree.

A study by the International Society of Arboriculture (ISA) found that proper training and adherence to safety protocols can significantly reduce the risk of accidents while tree climbing. That’s why this guide is so important.

Essential Equipment for Safe Tree Climbing

Having the right equipment is just as important as knowing how to use it.

Tree Climbing Spurs (Gaffs)

The spikes themselves are the foundation of your climbing system. Here’s what to consider when choosing them:

Type: There are two main types of spikes:
- Fixed Gaffs: The spike is permanently attached to the shank. These are typically more durable and preferred by experienced climbers.
- Replaceable Gaffs: The spike can be removed and replaced when it becomes worn or damaged. These offer convenience but require regular inspection to ensure they are securely attached.
Length: The length of the gaff determines how deeply it penetrates the wood. Longer gaffs provide a more secure hold but can be more difficult to maneuver. Shorter gaffs are easier to use but may not be suitable for trees with thick bark. The “sweet spot” is generally between 2 1/2 and 3 inches for most applications.
Material: Look for spikes made from high-quality steel that is both strong and durable. Avoid spikes made from inferior materials that may bend or break under stress.
Fit: The spikes should fit snugly and comfortably on your lower leg. Adjustable straps and pads can help you customize the fit.

Climbing Harness

Your harness is your lifeline. It distributes your weight and provides attachment points for your climbing line and other gear.

Type: Choose a harness specifically designed for tree climbing. These harnesses typically have multiple attachment points, padded leg loops, and a wide range of adjustability.
Comfort: A comfortable harness is essential for long days in the tree. Look for harnesses with ample padding and ergonomic designs.
Durability: Your harness should be made from high-quality materials that can withstand the rigors of tree climbing. Inspect it regularly for wear and tear.
Fit: The harness should fit snugly but not restrict your movement. Make sure the leg loops and waist belt are properly adjusted.

Climbing Line (Rope)

The climbing line is your primary means of ascent and descent. It’s what connects you to the tree and allows you to move safely.

Type: Use a rope specifically designed for tree climbing. These ropes are typically made from low-stretch materials like polyester or nylon and have a diameter of 11-13mm.
Length: The length of your climbing line should be at least twice the height of the tallest tree you plan to climb.
Strength: The climbing line should have a minimum breaking strength (MBS) of at least 5,000 lbs.
Inspection: Inspect your climbing line before each use for any signs of damage, such as cuts, abrasions, or discoloration.

Lanyard

A lanyard is a short rope or strap used to secure yourself to the tree while you’re working. It provides a secondary point of attachment in case your climbing line fails.

Type: Choose a lanyard specifically designed for tree climbing. These lanyards typically have adjustable lengths and locking carabiners.
Length: The length of your lanyard should be short enough to prevent a long fall but long enough to allow you to move comfortably around the tree.
Strength: The lanyard should have a minimum breaking strength (MBS) of at least 5,000 lbs.

Helmet

Protecting your head is non-negotiable. A helmet can prevent serious injury from falling branches or other debris.

Type: Use a helmet specifically designed for tree climbing or construction work. These helmets typically have a chin strap and impact-resistant shell.
Fit: The helmet should fit snugly and comfortably on your head. Make sure the chin strap is properly adjusted.
Inspection: Inspect your helmet regularly for any signs of damage, such as cracks or dents.

Eye Protection

Protect your eyes from sawdust, debris, and branches.

Type: Use safety glasses or goggles that meet ANSI Z87.1 standards.
Fit: The eye protection should fit snugly and comfortably on your face.

Gloves

Protect your hands from cuts, abrasions, and blisters.

Type: Use gloves specifically designed for tree climbing or work gloves made from leather or synthetic materials.
Fit: The gloves should fit snugly and comfortably on your hands.

First-Aid Kit

Always carry a well-stocked first-aid kit with you in case of an injury.

Contents: Your first-aid kit should include bandages, antiseptic wipes, pain relievers, and any other necessary medical supplies.

Other Essential Gear

Chainsaw: If you’re pruning or removing trees, you’ll need a chainsaw. Make sure you’re properly trained in chainsaw safety and operation.
Hand Saw: A hand saw is useful for smaller cuts and trimming.
Throw Line and Weight: A throw line and weight are used to set your climbing line in the tree.
Carabiners: Carabiners are used to connect your climbing line, lanyard, and other gear to your harness. Use locking carabiners that meet ANSI standards.

Expert Insight: “Don’t underestimate the importance of proper gear maintenance,” says veteran arborist Mark Johnson. “Regularly inspect your equipment for wear and tear, and replace it when necessary. Your life depends on it.”

Mastering the Techniques of Tree Climbing with Spikes

Now that you have the right gear, let’s talk about technique. Proper technique is essential for efficient and safe tree climbing.

The Two-Point System

The two-point system is the foundation of safe tree climbing. It means that you should always have at least two points of contact with the tree at all times – either two spikes in the tree, or one spike and your lanyard securely attached. This ensures that you are always supported and prevents you from falling if one point of contact fails.

Ascending: When ascending, maintain two points of contact with your spikes. As you move upward, alternate between your spikes, ensuring that one is always securely embedded in the wood before moving the other.
Descending: When descending, use the same two-point system. Lower yourself slowly and deliberately, ensuring that one spike is always securely embedded in the wood before moving the other.
Working: When working in the tree, use your lanyard to secure yourself to a branch or the trunk. This allows you to free up your hands and focus on the task at hand.

Setting Your Spikes

Properly setting your spikes is crucial for a secure and efficient climb.

Angle: Angle your spikes slightly upward when setting them. This will help prevent them from slipping out of the wood.
Depth: Ensure that the gaffs are fully embedded in the wood. You should feel a solid connection before putting your weight on them.
Placement: Avoid setting your spikes in areas where the bark is loose or the wood is rotten. Choose solid, healthy wood for the best grip.

Moving Up and Down the Tree

Ascending: To ascend, start by setting your spikes at a comfortable distance apart. Then, lean slightly into the tree and push yourself upward, alternating between your spikes. Use your arms to help pull yourself up, but avoid relying on them too much, as this will quickly fatigue you.
Descending: To descend, lean slightly away from the tree and lower yourself slowly, alternating between your spikes. Use your legs to control your descent and avoid dropping too quickly.

Using Your Lanyard Effectively

Your lanyard is your safety net. Use it to secure yourself to the tree whenever you’re working or taking a break.

Attachment: Attach your lanyard to a strong, healthy branch or the trunk of the tree. Use a locking carabiner to ensure a secure connection.
Adjustment: Adjust the length of your lanyard to allow you to move comfortably around the tree without having too much slack.
Movement: When moving around the tree, always detach and reattach your lanyard to ensure that you are always securely connected.

Advanced Climbing Techniques

Once you’ve mastered the basics, you can start exploring more advanced climbing techniques, such as:

Branch Walking: Using your spikes to walk along branches.
Rope Walking: Using your climbing line to traverse between branches.
Redirects: Using pulleys and carabiners to change the direction of your climbing line.

Personal Story: I remember one time when I was removing a large oak tree in a residential area. The tree was too close to the house to fell it in one piece, so I had to dismantle it from the top down. Using my spikes and climbing line, I carefully climbed to the top of the tree and began removing branches one by one. It was a challenging job, but the satisfaction of safely and efficiently dismantling the tree was immense.

Tree Assessment: Identifying Potential Hazards

Before you even think about climbing, take the time to thoroughly assess the tree for potential hazards. This is a crucial step in ensuring your safety.

Sound Test: Tap on the limbs with a tool or your hand. Dead or weak limbs will sound hollow or dull.
Flex Test: Gently push or pull on the limbs to see if they are stable. If they move excessively or feel weak, avoid putting your weight on them.

Checking for Decay or Rot

Decay or rot can weaken the tree’s structure and make it unsafe to climb.

Visual Inspection: Look for signs of decay or rot, such as fungal growth, soft spots, or cavities in the trunk or branches.
Sound Test: Tap on the trunk with a tool or your hand. Decayed or rotten wood will sound hollow or dull.
Probe Test: Use a probe or screwdriver to check for soft spots or cavities in the wood.

Identifying Electrical Hazards

Electrical lines are a serious hazard for tree climbers. Contact with a power line can be fatal.

Visual Inspection: Look for power lines running through or near the tree.
Distance: Maintain a safe distance from power lines at all times. The exact distance will vary depending on the voltage of the power line, but a general rule of thumb is to stay at least 10 feet away.
Notification: If you need to work near power lines, notify the utility company and request that they de-energize the lines.

Assessing the Tree’s Overall Stability

Consider the tree’s overall health and stability before climbing.

Lean: Is the tree leaning excessively to one side?
Root System: Is the root system healthy and stable?
Wind Exposure: Is the tree exposed to strong winds?
