outrigger

This term describes a stabilizing extension used across different engineering domains. In maritime contexts, it refers to the float that prevents a narrow hull from tipping, a design critical to traditional Pacific navigation. In aviation and naval architecture, it refers to structural beams that extend the reach of the main body to support wings or other external components.

In modern industrial settings, the term is most frequently associated with heavy machinery like cranes or boom lifts. These hydraulic arms are deployed to widen the vehicle's footprint, ensuring that the center of gravity remains stable during high-load lifts. Failure to properly deploy these supports is a common safety hazard in construction.
