Rapid lowering and a sudden stop that causes jerking of the load is known as ? a sling.

• A. Shock loading
• B. Setting
• C. Stretch setting
• D. Test loading

Answer: (A)

When a load is lowered quickly and then stopped abruptly, the sling experiences a sudden surge in force. The load’s inertia resists the change in motion, so the tension in the sling spikes beyond the static weight. This dynamic peak is what we call shock loading. It can push the sling beyond its rated capacity and cause failure if not controlled.

To prevent it, lower the load in a slow, controlled manner and use methods or devices that absorb energy or dampen the stop. This isn’t about simply setting up equipment or testing it; it’s about avoiding a rapid deceleration that creates a high-impact force on the sling.
