A trained and qualified person who prepares and attaches loads for lifting.
Q5. Who is a signal person?
A person who directs crane operations using standard hand signals or radio communication.
Q6. What is the center of gravity of a load?
The point at which the load’s weight is evenly distributed — crucial for balanced lifting.
Q7. Name three types of slings.
Wire rope slings, chain slings, synthetic web slings.
Q8. What is rated capacity?
The maximum load the lifting equipment or sling can safely handle.
Q9. How often must rigging equipment be inspected?
Before each use and periodically by a competent person per manufacturer/OSHA.
Q10. What is a critical lift?
A lift involving a load exceeding a certain percentage of crane capacity, complex conditions, or high risk.
Q11. What is a tagline and why is it used?
A rope attached to control load swing and rotation during lifting.
Q12. What is a shackle?
A U-shaped connector used to attach slings or hardware to loads.
Q13. Why is load weight calculation important?
To ensure equipment and slings are not overloaded.
Q14. What is the purpose of a load chart?
It shows the safe lifting capacities of a crane at various boom lengths and radii.
Q15. Why is training essential for lifting and rigging operations?
Workers must understand hazards, equipment limits, and communication protocols.
🔹 Section 2: Long Answer Questions (15 Examples)
Q16. Explain the steps in planning a lifting operation.
Identify load weight and center of gravity, select proper equipment, determine lifting points, assign qualified personnel, and prepare a lift plan.
Q17. Describe the responsibilities of a lifting supervisor.
Oversee planning, ensure equipment inspection, coordinate rigger and crane operator, and stop unsafe operations.
Q18. Discuss how to select the right sling for a job.
Consider load weight, shape, temperature, environment, and sling angle; follow manufacturer’s recommendations.
Q19. How would you prevent dropped loads?
Use proper rigging techniques, inspect equipment, maintain clear communication, and establish exclusion zones.
Q20. Explain the importance of sling angles in rigging.
Smaller angles increase load on slings; must calculate to avoid overload.
Q21. Describe inspection requirements for lifting equipment.
Pre-use visual checks, periodic inspections by a competent person, and records of maintenance.
Q22. How to ensure safe crane operation near power lines.
Maintain minimum clearance, de-energize lines if possible, or use insulating barriers.
Q23. What documentation should be maintained for lifting operations?
Lift plans, inspection reports, training records, and equipment certifications.
Q24. Discuss the role of a signal person during a lift.
Provides clear, standardized signals, maintains line of sight or radio communication, and ensures safe movement.
Q25. How can technology improve lifting safety?
Use of load monitoring devices, anti-collision systems, and digital lift planning apps.
Q26. Explain the difference between routine and non-routine lifts.
Routine lifts are repetitive and simple; non-routine are complex, requiring special planning and supervision.
Q27. Describe hazard controls for working under suspended loads.
Establish exclusion zones, do not stand under loads, and enforce barricades.
Q28. What are the employer’s responsibilities for lifting safety?
Provide certified equipment, ensure training, appoint qualified personnel, and enforce procedures.
Q29. How to manage multiple lifts at the same site.
Coordinate schedules, designate one lift supervisor, and communicate hazards.
Q30. Discuss common rigging hardware and their uses.
Shackles, hooks, turnbuckles, and eyebolts — each chosen for specific load attachment needs.
🔹 Section 3: Scenario-Based Questions (20 Examples)
Q31. Scenario: Rigger notices a frayed wire rope sling.
Answer: Tag out of service immediately, replace with inspected sling.
Q32. Scenario: Load weight unknown before lifting.
Answer: Do not lift until weight verified by documentation or calculation.
Q33. Scenario: Crane operating near power lines.
Answer: Maintain clearance, use a spotter, or de-energize lines.
Q34. Scenario: Load starts swinging dangerously during lift.
Answer: Lower load safely, use taglines, and reassess rigging.
Q35. Scenario: Signal person not visible to crane operator.
Answer: Stop lift until clear communication established via radio or alternate signaler.
Q36. Scenario: Two cranes lifting a single load.
Answer: Develop detailed lift plan, calculate load distribution, and coordinate operators.
Q37. Scenario: Sling angle less than 30 degrees.
Answer: Recalculate load on slings, adjust rigging to safer angle.
Q38. Scenario: Worker standing under suspended load.
Answer: Stop operation, clear area, reinforce exclusion zone.
Q39. Scenario: Hook safety latch missing.
Answer: Do not use hook until latch replaced.
Q40. Scenario: Wind speed exceeds safe limit.
Answer: Suspend lifting operations until conditions improve.
Q41. Scenario: Load exceeds rated capacity of crane.
Answer: Stop lift, select appropriate crane or reduce load.
Q42. Scenario: Rigging hardware not certified.
Answer: Reject equipment; only use certified and tested gear.
Q43. Scenario: Operator misinterprets hand signal.
Answer: Stop lift, clarify signal, retrain if necessary.
Q44. Scenario: Multiple lifts scheduled simultaneously in same area.
Answer: Sequence lifts, assign one supervisor, coordinate operations.
Q45. Scenario: Sling contact with sharp edges.
Answer: Use edge protection or softeners to prevent sling damage.
Q46. Scenario: Load tilts unexpectedly.
Answer: Lower load, adjust rigging points to align with center of gravity.
Q47. Scenario: Crane operator fatigued.
Answer: Replace operator, ensure rest periods.
Q48. Scenario: Tagline breaks during lift.
Answer: Lower load safely, replace tagline, and reassess control measures.
Q49. Scenario: Unauthorized person enters lift zone.
Answer: Stop lift, remove person, improve barriers and signage.
