Abstract
A quint configuration fire apparatus includes a chassis, a body assembly coupled to the chassis and having a storage area configured to receive a ground ladder and a fire hose, a pump coupled to the chassis, a water tank coupled to the chassis, a ladder assembly having a proximal end that is coupled to the chassis, a single front axle coupled to a front end of the chassis, and a single rear axle coupled to a rear end of the chassis. The center of gravity of at least one of the chassis, the body assembly, the pump, and the water tank are positioned to counterbalance a moment generated by a tip load with the ladder assembly extended to the horizontal reach of at least 90 feet.
Claims18
A quint configuration fire apparatus comprising:
- a chassis defining a longitudinal axis;
- a front axle;
- a rear axle;
- a body having storage configured to receive a ground ladder and a fire hose;
- a pump;
- a water tank;
- a ladder assembly;
- and
- a stability system including exactly two outriggers positioned between the front axle and the rear axle, wherein the exactly two outriggers are offset relative to one another along the longitudinal axis, wherein the exactly two outriggers are configured to protrude outward from opposing lateral sides of the chassis, and wherein the stability system engages a ground surface at no more than two contact points between the front axle and the rear axle;
- wherein the combination of (a) a center of gravity of at least one of the chassis, the body, the pump, or the water tank with (b) the stability system including the exactly two outriggers positioned between the front axle and the rear axle facilitates supporting a tip load of at least 750 pounds applied to a distal end of the ladder assembly while the ladder assembly is (a) extended to a horizontal reach of at least 90 feet and (b) rotated between a plurality of operating orientations.
