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, (ii) a rear downrigger coupled the chassis, or an outrigger coupled to the chassis. The stability system is controllable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface while maintaining full operational capability of the ladder assembly.
Claims20
A fire apparatus comprising:
- 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 including at least one of (i) a front downrigger coupled to the chassis, (ii) a rear downrigger coupled the chassis, or (iii) an outrigger coupled to the chassis;
- wherein the stability system is controllable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface while maintaining full operational capability of the ladder assembly.
A vehicle comprising:
- a chassis;
- a ladder assembly coupled to the chassis;
- a stability system coupled to the chassis, the stability system including extendable components that selectively engage a ground surface;
- and
- a control system configured to:
- control the stability system to level the vehicle;
- and
- enable the stability system to lean the vehicle when an operational capability of the ladder assembly is at a limit thereof while the vehicle is level to effectively improve the operational capability relative to when the vehicle is level.
A vehicle comprising:
- a chassis;
- a ladder coupled to the chassis;
- and
- a stability system coupled to the chassis, the stability system including a plurality of front downriggers, a plurality of rear downriggers, and a plurality of outriggers;
- wherein the stability system is controllable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface to effectively improve an operational capability of the ladder.
