Pedestal and torque box assembly for a fire apparatus

A quint configuration fire apparatus, comprising:

• a chassis defining a longitudinal direction and including a first frame rail spaced apart from a second frame rail, the first frame rail and the second frame rail defining a pair of frame rails;
• a single front axle coupled to a front end of the chassis;
• a single rear axle coupled to a rear end of the 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 torque box extending along the longitudinal direction and spanning the single rear axle thereby transferring loading along the chassis, the torque box including:
• a tubular body portion having a rectangular cross-sectional shape, a first end disposed rearward of the single rear axle, and an opposing second end disposed forward of the single rear axle;
• and
• a plate having a first wall disposed across a top surface of the tubular body portion, a first leg disposed along a sidewall of the tubular body portion, and a second leg disposed along an opposing second sidewall of the tubular body portion;
• wherein the torque box has a width equal to a spacing between laterally-outward surfaces of the first frame rail and the second frame rail;
• wherein the tubular body portion is stacked atop the pair of frame rails;
• and
• wherein the first leg and the second leg define a plurality of interfaces configured to engage a plurality of brackets that are attached to the pair of frame rails;
• a pedestal coupled to the torque box and disposed rearward of the single rear axle;
• a single set of outriggers coupled to the chassis and moveable between a fully extended position and a retracted position, wherein the single set of outriggers protrude from opposing lateral sides of the chassis when in the fully extended position;
• a ladder assembly including a plurality of extensible ladder sections, the ladder assembly coupled to the chassis with the pedestal and the torque box, wherein the ladder assembly is extensible to provide a horizontal reach of at least 100 feet and a vertical height of at least 105 feet;
• and
• a stability foot, wherein the opposing second end of the torque box is coupled to the single set of outriggers thereby defining a first load path from the ladder assembly to the single set of outriggers through the pedestal and the tubular body portion of the torque box, wherein the stability foot is coupled to the first end of the torque box thereby defining a second load path from the ladder assembly to the stability foot through the pedestal and the tubular body portion of the torque box.
