Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An aerial ladder assembly for a fire apparatus includes a base rail extending along a longitudinal direction, a hand rail elevated from the base rail and extending along the longitudinal direction, a first lacing member and a second lacing member coupling the hand rail to the base rail, the first lacing member and the second lacing member each including an end that engages the base rail at an interface, and a gusset positioned to reinforce the interface. The first lacing member and the second lacing member each define a slot that receives the gusset, and the gusset extends through the first lacing member and the second lacing member to the base rail.

Abstract: An aerial ladder assembly for a fire apparatus includes a first truss member, a second truss member, and a plurality of rungs coupling the first truss member to the second truss member. The first truss member includes a first base rail, a first hand rail elevated from the first base rail, and a plurality of lacing members coupling the first base rail to the first hand rail. The second truss member includes a second base rail, a second hand rail elevated from the second base rail, and a plurality of lacing members coupling the second base rail to the second hand rail. The first truss member and the second truss member define a first zone and a second zone separated by a transition, and the first base rail and the second base rail have a first shape within the first zone and a second shape within the second zone.

Abstract: Truss arrangements utilizable in ladder sections of extendible ladder arrangements are described. Also described are ladder arrangements utilizing in the truss arrangements, and methods designed in use.

Abstract: A torque box chassis frame for firefighting vehicles or the like constituting a platform for extendible aerial ladders. The vehicle torque box chassis frame includes elongated lower and upper members significantly spaced from each other having rigid bracing structure interposed therebetween resulting in a rigid elongated box of significant rectangular cross section dimension. The torque box chassis frame rear end is defined by a rigid ladder turntable support including its own vertical rigid columns, and spaced outrigger support tubes for receiving hydraulic outrigger jacks are integrally defined on the torque box chassis frame to provide firm support of the torque box upon the ground eliminating the influence of the vehicle suspension system.
