The choice depends on the load's characteristics and the lifting requirements.

4. How do you ensure the safety of yourself and others while operating a crane?

   • Answer: Safety is my top priority. I always conduct thorough pre-operational inspections, follow all safety regulations, wear appropriate PPE, communicate clearly with ground personnel using hand signals or radios, and maintain a safe distance from power lines and other hazards. I am also aware of and adhere to load limits and weight restrictions.

5. What are the common causes of crane accidents and how can they be prevented?

   • Answer: Common causes include improper rigging, exceeding weight limits, inadequate training, poor communication, and environmental factors like wind. Prevention involves thorough training, regular inspections, adherence to safety regulations, clear communication, and risk assessment before each lift.

6. Explain the importance of pre-operational checks before using a crane.

   • Answer: Pre-operational checks are crucial for identifying potential mechanical issues, ensuring safety, and preventing accidents. They involve checking brakes, structural integrity, electrical systems, load capacity, and rigging equipment before operating the crane.

7. How do you handle an emergency situation while operating a crane?

   • Answer: My immediate response is to secure the load safely, shut down the crane, and then assess the situation. I would then follow established emergency procedures, contact my supervisor, and report the incident. Depending on the emergency, I might need to evacuate personnel or call for emergency services.

I understand the importance of selecting the appropriate sling based on the load's weight, shape, and material. I also know how to properly inspect slings for wear and tear and identify any damage before use.

9. How do you calculate the safe working load (SWL) of a crane and its components?

   • Answer: The SWL is determined by referring to the crane's specifications and manufacturer's data plates. I understand that the SWL considers factors such as the crane's capacity, the boom length, and the angle of the boom. I also know how to calculate SWL for individual components like hooks and slings.
