An HEO is preparing to lift a 2,500 kg concrete barrier using a single-leg wire rope sling in a choker hitch. If the sling has a Working Load Limit (WLL) of 3,000 kg when used in a straight pull, what is its maximum allowable load when used in this choker hitch configuration? (Assume a Choker Hitch Efficiency Factor of 0.75 for wire rope slings).

Question: An HEO is preparing to lift a 2,500 kg concrete barrier using a single-leg wire rope sling in a choker hitch. If the sling has a Working Load Limit (WLL) of 3,000 kg when used in a straight pull, what is its maximum allowable load when used in this choker hitch configuration? (Assume a Choker Hitch Efficiency Factor of 0.75 for wire rope slings).

Answer options: ✅ 2,250 kg

• 3,000 kg
• 3,750 kg
• 1,875 kg

Correct answer: 2,250 kg

Explanation: To calculate the maximum allowable load in a choker hitch, multiply the sling's WLL by the choker hitch efficiency factor. For a wire rope sling, WLL (choker) = 3000 kg * 0.75 = 2250 kg. This capacity is less than the barrier's weight, so another method or sling configuration would be required.
