Using Cranes in Sectional Dismantling: Tips and Techniques

Introduction: Sectional dismantling is a precise tree removal technique often involving heavy machinery like cranes. Cranes can greatly enhance safety and efficiency regarding large and complex tree removals. In this blog post, presented by Thrapston Tree Surgeons, we’ll explore the use of cranes in sectional dismantling, offering valuable tips and techniques for a successful operation.

1. Assess the Tree and Site

Before deploying a crane for sectional dismantling, thoroughly assess the tree and the site. Consider factors such as:

  • Tree Health: Determine the tree’s overall health, structural issues, and dead or weakened branches.
  • Size and Height: Assess the tree’s size and height to determine if a crane is necessary.
  • Location: Evaluate the proximity of structures, power lines, and other obstacles that may impact the crane’s operation.
  • Clearance: Ensure enough space for the crane to manoeuvre safely.

2. Hire Experienced Crane Operators

Selecting a skilled and experienced crane operator is crucial. Look for operators with experience with tree removals and are familiar with the specific challenges of sectional dismantling. Verify their credentials and ensure they are licensed and insured.

3. Choose the Right Crane

The choice of crane depends on the tree’s size, location, and complexity. A mobile crane with an extended boom is typically used for sectional dismantling. Ensure that the crane has sufficient lifting capacity to handle the tree sections safely.

4. Plan Rigging Points

Work with your tree surgeon to plan the rigging points on the tree. These points should be secure branches or sections where the rigging equipment can be attached safely. Proper rigging is essential for the controlled lowering of tree sections.

5. Communicate Effectively

Maintain clear communication between the crane operator and the ground crew. Use two-way radios or hand signals to ensure everyone is on the same page. Effective communication is critical for safe and precise operations.

6. Rigging and Lowering

Rigging involves attaching ropes, slings, and other equipment to the tree sections. It’s essential to follow these principles:

  • Use appropriate rigging gear rated for the expected loads.
  • Rigging equipment should be inspected regularly for signs of wear or damage.
  • Ensure that rigging lines are correctly attached and tensioned.
  • Lower sections carefully and avoid sudden or jerky movements.

7. Monitor Weather Conditions

Keep a close eye on weather conditions during the operation. High winds, rain, or lightning can pose risks when using cranes. If adverse weather is approaching, consider postponing the work to ensure the safety of the crew and equipment.

8. Ensure Proper Stabilisation

Stabilise the crane by using outriggers or counterweights as needed. Proper stabilisation is essential for preventing the crane from tipping over during lifting and lowering operations.

9. Cleanup and Debris Removal

Plan for the removal of debris and ensure that there is adequate space for stacking sections. Discuss cleanup procedures with your tree surgeon to minimise post-operation disruption.

Conclusion: Using cranes in sectional dismantling requires careful planning, coordination, and expertise. By assessing the tree and site, hiring experienced crane operators, and following safety protocols, you can ensure the tree removal process is safe and efficient. Trusting professionals like Thrapston Tree Surgeons, who are well-versed in crane-assisted sectional dismantling, can make a significant difference in ensuring a successful tree removal operation while prioritising safety.
