Abstract
A fire apparatus includes a chassis, a body assembly coupled to the chassis, a front cabin coupled to a front end of the chassis forward of the body assembly, a front axle coupled to the front end of the chassis, at least one rear axle coupled to a rear end of the chassis, and a ladder assembly including at least one extensible ladder section. The ladder assembly has a proximal end that is coupled to the chassis rearward of the front cabin and between the front axle and the at least one rear axle. The ladder assembly is operable through a sweep angle greater than fifteen degrees while at a depression angle greater than eight degrees.
Claims18
A fire apparatus comprising:
- a chassis;
- a body assembly coupled to the chassis;
- a water tank coupled to the chassis, the water tank including one or more angled wall portions;
- a front cabin coupled to a front end of the chassis forward of the body assembly;
- a front axle coupled to the front end of the chassis;
- at least one rear axle coupled to a rear end of the chassis;
- and
- a ladder assembly including at least one extensible ladder section, the ladder assembly having a proximal end that is coupled to the chassis rearward of the front cabin and between the front axle and the at least one rear axle;
- wherein the ladder assembly is operable through a sweep angle greater than fifteen degrees while at a depression angle greater than eight degrees;
- and
- wherein the one or more angled wall portions at least partially facilitate the ladder assembly in traveling through the sweep angle while at the depression angle.
