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, a rear axle coupled to a rear end of the chassis, and a ladder assembly having a proximal end coupled to the chassis. The body assembly includes one or more angled portions. The one or more angled portions at least partially facilitate the ladder assembly in traveling through at least one of a sweep angle range or a depression angle range.
Claims19
A fire apparatus comprising:
- a chassis;
- a body assembly coupled to the chassis, the body assembly including a water tank and one or more angled portions, wherein the water tank defines at least one of the one or more angled 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;
- a rear axle coupled to a rear end of the chassis;
- and
- a ladder assembly having a proximal end coupled to the chassis;
- wherein the one or more angled portions at least partially facilitate the ladder assembly in traveling through at least one of a sweep angle range or a depression angle range.
A fire apparatus comprising:
- a chassis;
- a body assembly coupled to the chassis, the body assembly including one or more angled 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;
- a rear axle coupled to a rear end of the chassis;
- and
- a ladder assembly having a proximal end coupled to the chassis;
- wherein the one or more angled portions at least partially facilitate the ladder assembly in traveling through at least one of a sweep angle range or a depression angle range;
- wherein the ladder assembly includes a base ladder section and an extensible ladder section;
- wherein a first proximal end of the base ladder section is pivotally coupled to the chassis by an intermediate structure about a pivot axis;
- wherein the extensible ladder section is slidably coupled to the base ladder section;
- and
- wherein the extensible ladder section is selectively over-retractable such that (i) a second proximal end of the extensible ladder section is retractable past the first proximal end of the base ladder section and (ii) the extensible ladder section spans across the pivot axis.
A ladder assembly for a vehicle, the ladder assembly comprising:
- a base ladder section having a first proximal end, the base ladder section configured to be coupled to a chassis of the vehicle;
- an extensible ladder section having a second proximal end, the extensible ladder section slidably coupled to the base ladder section;
- wherein the extensible ladder section is selectively over-retractable such that the second proximal end of the extensible ladder section is retractable past the first proximal end of the base ladder section.
A vehicle comprising:
- a chassis;
- and
- a ladder assembly coupled to the chassis, the ladder assembly including:
- a base ladder section having a first proximal end;
- and
- an extensible ladder section having a second proximal end, the extensible ladder section slidably coupled to the base ladder section;
- wherein the extensible ladder section is selectively over-retractable such that the second proximal end of the extensible ladder section is retractable past the first proximal end of the base ladder section.
