Lifting roof trusses with a crane is a critical task in construction that requires careful planning, precision, and adherence to safety protocols. Roof trusses are essential structural components that provide support to the roof, and improper handling can lead to structural failures or accidents. In this blog post, we will guide you through the steps and considerations involved in lifting roof trusses with a crane.

Preparation and Planning
Before lifting any roof truss, thorough preparation and planning are crucial. Here are the steps to follow:
-
Site Assessment: Evaluate the construction site to identify any potential hazards or obstacles that could interfere with the lift. Ensure there is enough space for the crane to operate safely.
-
Crane Selection: Choose a crane that is appropriate for the weight and size of the roof trusses. Consider the crane’s lifting capacity, reach, and manoeuvrability. A 32 Tonne HIAB with a long reach such as a Long reach FASSI crane, is perfect for the job.
-
Truss Inspection: Inspect the roof trusses for any damage or defects. Ensure they are properly assembled and ready for lifting.
Rigging the Trusses
Proper rigging is essential for a safe and successful lift. Follow these steps to rig the trusses correctly:
-
Attachment Points: Identify the correct attachment points on the trusses. These are usually marked by the manufacturer and are designed to handle the load.
-
Slings and Shackles: Use appropriate slings and shackles to secure the trusses. Ensure they are rated for the weight of the trusses and are in good condition.
-
Balancing the Load: Make sure the trusses are balanced to prevent tilting or swinging during the lift. Use spreader bars if necessary to distribute the weight evenly.
Lifting the Trusses
With the trusses rigged and the site prepared, it’s time to lift the trusses. Here’s how to proceed:
-
Safety Briefing: Conduct a safety briefing with the crane operator and all personnel involved in the lift. Review the lift plan and emergency procedures.
-
Slow and Steady: Begin the lift slowly and steadily. Avoid sudden movements to prevent swinging or dropping the trusses.
-
Communication: Maintain clear communication between the crane operator and the ground crew. Use hand signals or radios to coordinate the lift.
Placing the Trusses
Once the trusses are lifted, they need to be placed accurately. Here are the steps for proper placement:
-
Guiding the Trusses: Use tag lines to guide the trusses into position. Ensure the ground crew is positioned safely away from the load.
-
Alignment: Align the trusses with the marks or guides on the building structure. Precision is key to ensuring the trusses fit correctly.
-
Securing the Trusses: Once in place, secure the trusses immediately to prevent movement. Use temporary braces or fasteners as needed.
Safety Considerations
Safety is paramount when lifting roof trusses with a crane. Keep the following safety tips in mind:
-
Weather Conditions: Avoid lifting in adverse weather conditions such as high winds, rain, or lightning.
-
Personal Protective Equipment (PPE): Ensure all personnel wear appropriate PPE, including hard hats, gloves, and high-visibility clothing.
-
Load Limits: Never exceed the crane’s load limits. Always follow the manufacturer’s guidelines for safe operation.
-
Regular Inspections: Conduct regular inspections of the crane, rigging equipment, and trusses to identify and address any potential issues.
Conclusion
Lifting roof trusses with a lorry mounted crane is a complex task that requires meticulous planning, proper equipment, and strict adherence to safety protocols. By following the steps outlined above, you can ensure a safe and successful lift, minimising the risk of accidents and ensuring the structural integrity of your building.
