Setting Up the Rigging: First, we set up the ropes and anchors in the tree, ensuring everything is secure. We typically use strong ropes tied to certain branches or a sturdy part of the tree to create a system that we can control.
Securing the Cut: We make the necessary cuts in the tree, typically from the top down. As we cut, we attach ropes to the section we want to remove, so that when it’s cut, it can be lowered in a controlled way.
Lowering the Branches: Using a combination of pulleys and ropes, we gently lower the branches or pieces of the trunk to the ground. This allows us to safely guide large or heavy sections down without them falling uncontrollably.
Final Clean-Up: Once the sections are safely on the ground, we remove them in manageable pieces. This helps ensure that we don’t damage anything, and everything is removed safely.
"Essentially, rigging allows us to take down sections of the tree in a precise and safe manner, reducing risk to you, your property, and the people around us."
When rigging, a tree surgeon uses a variety of specialized equipment to ensure the safe and efficient removal of tree branches or sections. Here’s a list of the key equipment needed for tree rigging:
Tree Climbing Rope: A strong, static rope that the tree surgeon uses for climbing or securing themselves within the tree.
Rigging Ropes: These are typically dynamic ropes designed for rigging purposes. They are used to lower branches or sections in a controlled manner.
Throw Line: A lightweight rope used to toss over higher branches to anchor rigging ropes in place.
Rigging Pulleys: Used to redirect the rope or change the direction of the load. They help distribute the weight of the section being lowered and make the descent smoother and more controlled.
Block and Tackle: A type of pulley system that allows for easier movement of heavier sections by giving mechanical advantage.
Locking Carabiners: These are metal clips used to secure ropes to the tree, pulleys, or other anchor points. Locking carabiners help prevent accidental detachment.
Tree Slings or Rigging Slings: Used to wrap around tree sections or branches to secure them to the rigging ropes. They can be made from webbing or chain and are essential for holding heavy sections.
Rigging Plates: These are used to distribute the load across several ropes or anchors, helping to reduce the pressure on a single point and prevent damage to the tree or surrounding area.
Prusik Knot: A knot used for ascending or securing a rope. In rigging, it can be used as an emergency backup to secure a rope or prevent movement.
Mechanical Prusik: A mechanical device that provides extra safety and control when ascending or descending.
Chainsaw: A crucial tool for cutting branches or tree sections. The tree surgeon uses this to remove parts of the tree that will be rigged.
Hand Saws/Climbers' Saws: For finer, controlled cuts when necessary.
Wood Chipper: While not directly part of rigging, the wood chipper is commonly used on the ground to dispose of smaller branches after they are lowered.
Helmet: With a face shield or visor for protection from falling debris.
Harness and Lanyard: The tree surgeon will wear a climbing harness and a lanyard to secure themselves to the tree while working.
Gloves: For handling ropes and other equipment safely.
Protective Boots: Steel-toed boots help prevent injury from falling debris or tools.
Load Spreader: In some cases, a load spreader may be used to ensure the load is evenly distributed when a heavy section is being lowered.
Ratchet Straps or Winches: For additional support when lifting or pulling heavy sections during rigging.
By using this equipment, a tree surgeon can safely rig and lower tree sections, ensuring that the work is done efficiently while minimizing risks to people and property.
