Abstract

A vehicle includes a chassis defining a longitudinal axis, a cab coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a body assembly coupled to the chassis, and an implement. The body assembly defines a recess that includes a plurality of angled portions. The plurality of angled portions extend laterally outward at a downward angle away from the longitudinal axis. The implement has a proximal end disposed within the recess. The plurality of angled portions at least partially facilitate the implement in traveling through at least one of a sweep angle range or a depression angle range.

First claim

The invention claimed is:

1 . A vehicle comprising:
a chassis defining a longitudinal axis; a cab coupled to the chassis; a front axle coupled to the chassis; a rear axle coupled to the chassis; a body assembly coupled to the chassis, the body assembly defining a recess that includes a plurality of angled portions, the plurality of angled portions extending laterally outward at a downward angle away from the longitudinal axis; and an implement having a proximal end disposed within the recess; wherein the plurality of angled portions at least partially facilitate the implement in traveling through at least one of a sweep angle range or a depression angle range: wherein the implement includes a ladder assembly; wherein the vehicle is a rear-mount fire apparatus or a mid-mount fire apparatus; wherein the ladder assembly includes a basket coupled to a distal end thereof; wherein the ladder assembly is repositionable such that a platform of the basket is accessible from a ground surface with the ladder assembly in a fully-retracted configuration; and wherein the ladder assembly is repositionable such that the platform of the basket is positionable 20.3 inches or less above the ground surface without extending the ladder assembly.

2 . The vehicle of claim 1 , wherein the plurality of angled portions at least partially facilitate the implement in traveling through the sweep angle range while at a depression angle.

3 . The vehicle of claim 2 , wherein the sweep angle range is greater than fifteen degrees, and wherein the depression angle range is greater than eight degrees.

4 . The vehicle of claim 1 , wherein the body assembly includes a water tank, wherein the recess is positioned between the cab and the water tank.

5 . The vehicle of claim 4 , wherein a front wall of the water tank has an angled profile.

6 . The vehicle of claim 1 , wherein the implement is coupled to the chassis rearward of the cab and between the front axle and the rear axle.

7 . The vehicle of claim 1 , wherein the ladder assembly extends at most twenty feet from a side of the body assembly when (i) pivoted to a side of the vehicle, (ii) oriented horizontal, and (iii) the ladder assembly is in a fully-retracted configuration.

8 . The vehicle of claim 1 , wherein the basket extends at most 19.5 feet from a side of the vehicle when the platform of the basket is accessible from the ground surface.

9 . The vehicle of claim 1 , wherein the ladder assembly includes a base ladder section and an extensible ladder section, and wherein the extensible ladder section is selectively over-retractable such that a proximal end of the extensible ladder section is retractable past a proximal end of the base ladder section.

10 . The vehicle of claim 9 , wherein the proximal end of the extensible ladder section overhangs a pump of the vehicle when the extensible ladder section is over-retracted and the ladder assembly is in a stowed position.

11 . The vehicle of claim 9 , wherein the extensible ladder section spans across a pivot axis of the ladder assembly when the extensible ladder section is over-retracted.
