What are outriggers used for in machinery?

Outriggers are primarily used to provide lateral stability to machinery, especially in equipment such as cranes and aerial lifts. When deployed, outriggers extend outward from the base of the machinery, effectively widening the footprint. This increased footprint allows the machine to safely operate with heavy loads and at significant heights by distributing weight more evenly and reducing the risk of tipping or lateral movement.

In terms of the other options, while outriggers may indirectly influence horizontal reach or load capacity by enhancing stability, their primary design function is not to increase these factors directly. Similarly, while outriggers might allow for a more secure lift at greater heights, they do not extend the working height of the machine itself but rather contribute to safer operation when working at those heights. Thus, the main role of outriggers remains focused on providing necessary stability during operation.
