How to Gaff Trees

Arborists needing to reach extreme heights employ safety equipment such as tree gaffs.

Tree gaffs, or spurs, are used to help arborists and lumber harvesters climb up trees safely. Constructed to fit over climbers' boots for support, gaffs include a steel apparatus for each leg secured by straps around the calf and ankle. Leather pads are arranged to go around the calf for more support and comfort and to evenly distribute weight. Spikes are also attached to the climbing support to help the climber get a purchase on the tree. For the proper fit and optimum safe use, gaff supports must be measured.

Things You'll Need

• Gaff supports
• Clamps
• File
• Gloves
• Helmet
• Rope
• Safety harness

Instructions

1. Sharpen the gaff so you get the best purchase in the tree trunk. Put the support in clamps with the gaff pointing out. Run a file up and down the gaff in a smooth motion. Test the sharpness of the gaff with the edge of your thumb.

2. Strap the gaff supports around your calves. Fasten both straps tightly but give yourself enough flexibility to bend your ankle comfortably. The supports should bite to just a half inch below the bone in your knee.

3. Put on a helmet and gloves. Inspect the foot straps, stirrup and all other parts of the gaff supports. Run one side of the rope through the safety belt loops, then secure the belt to your waste. Wrap the rope around the tree and secure it to the other side of the safety belt. Leave 2 feet of space between you and the tree.

4. Raise the rope up and set a foot into the bark of the tree so the gaff catches by approximately 2 inches. Step up with the next foot and do the same thing. Lift the rope up higher and move the first foot up a comfortable level. Keep "walking" up the tree in this way, using the rope as a sling to rest and support your upper body.
