What are outriggers used for on a boom lift?

Outriggers on a boom lift are primarily used to provide stability and balance during operation. When the lift is extended to great heights, the center of gravity can shift significantly, which can create a risk of tipping. Outriggers help to stabilize the lift by extending outward from the base, creating a wider footprint and distributing the weight more evenly. This enlarged base essentially lowers the risk of the boom lift becoming unstable, especially when it is raised or when it is being used on uneven ground.

The other options do not accurately describe the function of outriggers. For instance, they do not lift additional weights, enhance ascent speed, or reduce operational noise. Instead, their main role is to ensure safety by maintaining a solid and balanced platform for operators working at heights.
