100 Building Rigger Interview Questions and Answers

  1. What is the most important aspect of your job as a building rigger?

    • Answer: Safety. Ensuring the safety of myself, my crew, and the public is paramount. This includes proper planning, execution, and adherence to all safety regulations and procedures.

  2. Describe your experience with different types of rigging equipment.

    • Answer: I have extensive experience with [List specific equipment, e.g., wire ropes, slings, shackles, chains, beams, lifting points, various types of cranes, etc.]. I understand the limitations and safe working loads of each piece of equipment and can select the appropriate equipment for various lifting tasks.

  3. Explain the process of rigging a heavy load for lifting.

    • Answer: The process begins with a thorough risk assessment. Then, I determine the weight and center of gravity of the load, select appropriate lifting equipment, and calculate the required rigging configuration. This includes determining the number and type of slings, their angles, and the placement of shackles and other hardware. Finally, I ensure all equipment is inspected and in good working order before commencing the lift.

  4. How do you ensure the safety of workers during rigging operations?

    • Answer: Safety is paramount. I implement strict safety protocols, including pre-lift inspections, regular communication with the crane operator, designated signal persons, and ensuring workers are properly trained and equipped with PPE (Personal Protective Equipment). I enforce a strict no-go zone around the lifting operation.

  5. What are the different types of slings and their applications?

    • Answer: Common sling types include wire rope slings (for heavy loads and abrasive environments), chain slings (for heavy, sharp or abrasive loads), and synthetic web slings (for lighter loads and delicate materials). Each type has specific applications and limitations depending on the load and environmental conditions.

  6. How do you calculate the safe working load (SWL) of a rigging assembly?

    • Answer: The SWL is determined by considering the SWL of each component in the assembly (slings, shackles, hooks, etc.) and the angle of the slings. The weakest component determines the overall SWL. I always use the manufacturer's data and apply relevant safety factors.

  7. What are the common hazards associated with rigging work?

    • Answer: Hazards include dropped loads, crushing injuries, electrocution, entanglement, falls from height, and equipment failure. Understanding and mitigating these hazards is crucial.

  8. How do you handle unexpected situations during a rigging operation?

    • Answer: I remain calm and assess the situation quickly. I communicate clearly with the team and crane operator. If necessary, I stop the operation immediately and take corrective action. Reporting procedures are followed.

  9. What are your experiences with different types of cranes?

    • Answer: I have experience with [list specific crane types, e.g., tower cranes, mobile cranes, overhead cranes]. I understand their limitations and operating procedures.

  10. Describe your experience with load testing and inspection of rigging equipment.

    • Answer: I regularly inspect rigging equipment for wear and tear, damage, and proper functioning. Load testing is conducted according to established procedures and regulations to verify the equipment's integrity.
