Abstract
A vehicle includes a chassis, an implement assembly coupled to the chassis, a stability system coupled to the chassis, and a control system. The stability system includes extendable components that selectively engage a ground surface. The control system is 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 implement assembly is at a limit thereof while the vehicle is level to effectively improve the operational capability relative to when the vehicle is level.
Claims20
A vehicle comprising:
- a chassis;
- an implement 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 implement 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;
- an implement 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;
- enable the stability system to lean the vehicle;
- and
- derate an operational capability of the implement assembly in response to the stability system leaning the vehicle more than a threshold amount.
A fire apparatus comprising:
- a chassis;
- an implement assembly coupled to the chassis, the implement assembly including an extendable ladder and a basket having a platform;
- 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 fire apparatus;
- and
- enable the stability system to lean the fire apparatus;
- wherein the platform is positionable less than or equal to 20.3 inches above the ground surface without leaning the fire apparatus and without extending the extendable ladder.
