Storm Damaged Sectional Felling With Span Rigging

In this recent case study, one of our arborists, Andrius, was filmed on site carrying out the sectional felling of a storm-damaged tree using a specialist technique called span rigging. The video captures the precision, teamwork and control required when removing an unsafe tree in a confined or sensitive area.

The Challenge

Following severe weather, the tree had suffered structural damage that made it unsafe to leave standing. Due to its condition and surrounding environment, it could not be felled in one piece. Instead, the tree needed to be dismantled in controlled sections to prevent damage to nearby property and ensure the safety of the team and the public.

The Solution

Andrius carried out the removal by climbing the tree and dismantling it piece by piece. Each section was carefully cut and controlled using span rigging, allowing the timber to be lowered safely rather than dropped.

This approach reduces impact on the ground, prevents shock loading to the tree and surrounding area, and gives the team full control over every movement.

What Is Span Rigging?

For those new to tree work, span rigging is a method used to safely control large or heavy tree sections during removal.

Instead of lowering a branch straight down, a rigging line is tensioned between two anchor points, creating a “span”. When a section is cut, it travels along this line in a controlled way, much like a cable system.

Why Arborists Use Span Rigging

• Allows heavy timber to be moved away from obstacles

• Reduces impact forces on the tree and anchor points

• Improves control in tight spaces

• Increases safety for climbers and ground staff

• Prevents damage to property, fences and surfaces below

Span rigging is especially useful in storm-damaged trees, where traditional lowering methods may place too much stress on already weakened wood.
