cable rigger Interview Questions and Answers

1. What is your experience with different types of rigging hardware?

   • Answer: I have extensive experience with shackles, hooks, slings (chain, wire rope, synthetic), wire rope clips, turnbuckles, spreader beams, and other related hardware. I understand their weight limits, safe working loads (SWLs), and proper inspection procedures for each.

2. Explain the importance of pre-lift planning.

   • Answer: Pre-lift planning is crucial for safety and efficiency. It involves assessing the load's weight, dimensions, center of gravity, rigging points, and the environment. This helps determine the appropriate rigging equipment, lifting method, and personnel required to execute the lift safely and prevent accidents.

3. How do you ensure the safe operation of a crane during a lift?

   • Answer: Safe crane operation involves confirming the crane's capacity exceeds the load weight, verifying the crane's stability on the ground, using proper signaling procedures with the crane operator, maintaining a safe distance from the swing radius, and continually monitoring the lift for any anomalies.

4. Describe your experience with different types of slings.

   • Answer: I'm proficient with chain slings, wire rope slings, and synthetic web slings. I understand the strengths and weaknesses of each type, their appropriate uses, and how to inspect them for wear and tear. I know how to properly angle slings to distribute the load effectively and avoid damage.

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

   • Answer: The SWL of a rigging assembly is determined by the lowest SWL of any component within the assembly. This requires knowing the SWL of each individual component (sling, shackle, hook etc.) and accounting for any angle factors involved in the rigging configuration.

6. What are the common causes of rigging accidents?
