The traction motor is configured to rotate the second rotor about a rolling axis, and the traction motor is positioned within an opening in the first rotor. The motor system also includes an axle positioned coaxial to the second rotor and coupled to the first rotor such that the traction motor rotates about the steering axis as the steering motor rotates the first rotor about the steering axis.

A system for assembling roofing at ground level has an adjustable-length center frame separating a first assembly side from a second assembly side; a first cantilevered gantry on the first assembly side and a second cantilevered gantry on a second side, each cantilevered gantry moveable along the length of the center frame; a plurality of outrigger beams coupled to opposing ends of the center beam, each outrigger beam having a catwalk thereon; a first joist railing and a second joist railing on each assembly side, each joist railing configured to receive an end of an open web joist; and a base frame comprising a plurality of wheels. Once the roofing section has been assembled, hoisting the assembled roofing section to the top of a structure.

A modular subbase may comprise an upper surface, a longitudinal supporting structure coupled to the upper surface, one or more outrigger boxes coupled to the longitudinal supporting structure and the upper surface. The longitudinal supporting structure may comprise a wide sheet of metal comprising two upwardly-facing arms and a medial section adapted to be lightweight and to provide structural support to the upper surface. The longitudinal supporting structure and upper surface may comprise struts configured to prevent buckling of the medial section and the upper surface The modular subbase may be configured to couple to one or more modular bodies. The modular bodies may couple directly to the upper surface. A boom-arm pedestal for operating a boom-arm may be integrated into the upper surface and may be structurally supported by the modular subbase.

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 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 quint configuration fire apparatus includes a chassis defining a longitudinal axis, a front axle, a single rear axle having a gross axle weight rating of less than or equal to 33,500 pounds, a body having storage configured to receive a ground ladder and a fire hose, a pump, a water tank, a ladder assembly having a proximal end supported by the chassis proximate a rear end of the chassis, and a stability system. The quint configuration fire apparatus supports a tip load of at least 750 pounds applied to a distal end of the ladder assembly while the ladder assembly is (a) extended to a horizontal reach of at least 90 feet and (b) rotated between a plurality of operating orientations.

A system for assembling roofing at ground level has an adjustable-length center frame separating a first assembly side from a second assembly side; a first cantilevered gantry on the first assembly side and a second cantilevered gantry on a second side, each cantilevered gantry moveable along the length of the center frame; a plurality of outrigger beams coupled to opposing ends of the center beam, each outrigger beam having a catwalk thereon; a first joist railing and a second joist railing on each assembly side, each joist railing configured to receive an end of an open web joist; and a base frame comprising a plurality of wheels. Once the roofing section has been assembled, hoisting the assembled roofing section to the top of a structure.

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.

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 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.
