What is the recommended configuration for lifting a round object (drum) to avoid deformation?

• A. Use a basket hitch or two-leg sling under the load to distribute pressure and prevent crushing.
• B. Use a single leg sling over the top to grip the drum.
• C. Attach directly to the drum with rope.
• D. Use a three-leg sling with a central ring.

Answer: (A)

Distributing pressure evenly around a round object is essential to prevent deformation during lifting. A basket hitch or two-leg sling placed under the load creates a cradle that supports the drum’s curved surface, spreading the pressure across a broad area rather than concentrating it on a small point. This reduces the risk of crushing the walls or rims and helps keep the drum stable as it’s hoisted.

Using a single leg sling over the top concentrates pressure on a narrow region and can crush or dent the rims, risking damage and loss of control. Attaching rope directly to the drum can gouge the surface and offers poor, uneven support. A three-leg sling with a central ring can produce uneven loading and instability. Overall, the basket hitch or two-leg sling under the load provides the best distribution of force and minimizes deformation during lifting.
