Abstract
A fire apparatus includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a ladder assembly coupled to the chassis, and a stability system. The stability system includes at least one of (i) a front downrigger coupled to the chassis or (ii) a rear downrigger coupled the chassis, and an outrigger coupled to the chassis. The at least one of (i) the front downrigger or (ii) the rear downrigger and the outrigger are extendable and retractable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface while maintaining full operational capability of the ladder assembly.
