What is the purpose of using a two-leg sling under a round drum?

• A. Distribute pressure and prevent crushing.
• B. To lift weight faster.
• C. To leave less slack.
• D. To reduce the need for other rigging.

Answer: (A)

Distributing pressure to prevent crushing is the goal when using a two-leg sling under a round drum. A round drum has curved surfaces, so a single point or narrow contact can indent, deform the drum, or crush the flare where the sling sits. By using two legs under the drum, the load is spread over a larger contact area, lowering the peak pressure on any one point. This cradle-like setup helps keep the drum’s shape intact and protects the sling and the drum from damage during the lift. It also improves stability, making the lift safer and easier to control.

The other options miss the important safety idea here. Lifting faster doesn’t address protecting the drum from crushing, leaving less slack isn’t about distributing load, and reducing the need for other rigging doesn’t tackle the risk of damage to the drum or sling.
