What feature do some bucket trucks have to assist in lowering a victim?

Bucket trucks may be equipped with a tilting feature that provides a critical advantage in emergency situations, specifically when it comes to the safe lowering of a victim. The ability to tilt the bucket allows the operator to adjust the angle and orientation of the bucket to facilitate the easiest and safest descent for an injured or incapacitated individual. This feature helps in minimizing further injury and ensures a more controlled and stable lowering process.

In contrast, options such as extending or raising the bucket are primarily designed to increase height or reach but do not effectively contribute to the safe and gradual lowering of a person in distress. The swiveling capability of the bucket allows for rotation but does not assist in lowering the victim safely to the ground. Therefore, the tilting function specifically addresses the need for careful positioning and lowering, making it the best choice for this context.
