What kind of stability does an EWP gain from using outriggers?

Outriggers significantly enhance the stability of an Elevated Work Platform (EWP) by widening the base of the equipment. This increased horizontal stability is crucial for safe operation, especially when the platform is elevated. By deploying the outriggers, the machine's center of gravity is effectively lowered and its footprint is expanded, which reduces the risk of tipping over when the platform is extended or when it is subjected to lateral forces, such as wind or uneven surfaces.

The other options, while relevant to various aspects of EWP operation, do not specifically relate to the function and benefit of outriggers. Vertical speed pertains to the ascent and descent capabilities of the lift but does not influence its stability. Weight reduction could be a consideration in equipment design but does not directly tie to the purpose or benefits of outriggers. Operator comfort is important for overall safety and efficiency but is not a function of the outrigger system. Therefore, the primary advantage of using outriggers is the significant increase in horizontal stability they provide.
