A ladder assembly for a fire apparatus includes a first ladder section, a second ladder section extendible relative to the first ladder section, and a slide pad positioned between the first ladder section and the second ladder section. The slide pad includes a body portion, a first engagement surface extending from the body portion, and a second engagement surface extending from the body portion. The first engagement surface is spaced an offset distance from the second engagement surface.

A ladder assembly for a fire apparatus includes a base rail, a hand rail, a first lacing member, a second lacing member, and a gusset. The first lacing member and the second lacing member extend between the base rail and the hand rail. Both the first lacing member and the second lacing member engage the base rail at an interface. Each of the first lacing member and the second lacing member defines a slot along only a portion of a length thereof. Portions of the gusset are received by the slot of the first lacing member and the slot of the second lacing member. The gusset engages the base rail to reinforce the interface.

A turntable for a ladder assembly of a fire apparatus includes a base plate, a first set of side plates coupled to the base plate, a second set of side plates coupled to the base plate, a first bracket coupled to the base plate, a second bracket coupled to the base plate, a subfloor assembly releasably coupled to the first bracket and the second bracket with a plurality of fasteners, and a work platform coupled to the subfloor assembly. The first set of side plates extend vertically upward from a first side of the base plate. The second set of side plates extend vertically upward from an opposing second side of the base plate. The first bracket extends rearward from the base plate proximate the first side thereof. The second bracket extends rearward from the base plate proximate the opposing second side thereof.

A support structure for a ladder assembly of a fire apparatus includes a torque box, a pedestal, and a support plate. The torque box includes a top surface defining an aperture. The pedestal has (i) a lower end received by the aperture of the torque box and (ii) an upper end configured to couple to the ladder assembly. The support plate is positioned along the top surface of the torque box. The support plate includes a first leg and a second leg. The first leg extends from a first side of the support plate and is configured to engage with a first rail of the fire apparatus. The second leg extends from an opposing second side of the support plate and is configured to engage with a second frame rail of the fire apparatus.

A ladder assembly includes a ladder and a basket. The ladder has a first end and an opposing second end configured to couple to the fire apparatus. The basket is coupled to the first end of the ladder. The basket includes a subfloor frame assembly, a floor panel coupled to the subfloor frame assembly, and an upper frame assembly extending upward from and around a periphery of the floor panel. The upper frame assembly includes a front portion, a rear portion, opposing side portions coupled to the rear portion; and a pair of doors extending between the front portion and the opposing side portions. The pair of doors are positioned proximate front corners of the basket and oriented at an angle relative to the front portion and the opposing side portions.
