Aerial ladders may be provided on a mobile platform or a vehicle, such as a fire apparatus (e.g., a fire truck, etc.). Such aerial ladders are extendable structures having components that telescope relative to one another. Fire fighters may pivot and extend the aerial ladder upward and outward from the fire apparatus to advantageously elevate and position an end of the aerial ladder. By way of example, the end of the aerial ladder may include a nozzle, and positioning the nozzle may facilitate discharge of water therefrom. By way of another example, the end of the aerial ladder may include a platform or basket, and positioning the end of the aerial ladder may facilitate a rescue operation.
The aerial ladder is coupled to the fire apparatus at one end. When pivoted upward, the aerial ladder forms a cantilever structure that is subject to loading from the weight of the aerial ladder itself and to loading from any persons or equipment on the aerial ladder. Such loading causes deflection along the length of the aerial ladder. Aerial ladders are designed using materials and structural components that reduce deflection at the end of the aerial ladder.
One embodiment relates to an aerial ladder assembly for a fire apparatus that 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.
Another embodiment relates to an aerial ladder assembly for a fire apparatus that 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 extend along a longitudinal direction, and the plurality of rungs extend across the longitudinal direction. 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.
Still another embodiment relates to a fire apparatus that includes a chassis, a single front axle assembly coupled to the chassis, a single rear axle assembly coupled to the chassis, and an aerial ladder assembly that is coupled to the chassis and defines a longitudinal direction. The aerial ladder assembly includes a base rail extending along the 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, and a gusset. The first lacing member and the second lacing member each include an end that engages the base rail at an interface, and the gusset is 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.
The invention is capable of other embodiments and of being carried out in various ways. Alternative exemplary embodiments relate to other features and combinations of features as may be recited herein.
The disclosure will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements, in which:
Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.
According to an exemplary embodiment, an aerial ladder assembly is operable within a work envelope defined at least in part by a vertical extension height and a horizontal reach distance. The aerial ladder assembly has a structural truss design that reduces weight while improving vertical extension height and horizontal reach. Traditionally, a “Quint” configuration fire apparatus (e.g., a fire apparatus having a fire fighting ladder mounted on a single rear axle chassis, etc.) has a vertical extension height of 75-80 feet and 67-72 feet of horizontal reach. Traditionally, increasing extension height or horizontal reach requires increasing the weight of the aerial ladder assembly and supporting the aerial ladder assembly with a tandem rear axle chassis. A tandem rear axle may include two solid axle configurations or may include two pairs of axles (e.g., two pairs of half shafts, etc.) each having a set of constant velocity joints and coupling two differentials to two pairs of hub assemblies. A single rear axle chassis may include one solid axle configuration or may include one pair of axles each having a set of constant velocity joints and coupling a differential to a pair of hub assemblies, according to various alternative embodiments. According to an exemplary embodiment of the present application, the aerial ladder assembly has a vertical extension height of at least 95 feet (e.g., 105 feet, 107 feet, etc.) and at least 90 feet (e.g., at least 100 feet, etc.) of horizontal reach with a tip capacity of at least 750 pounds and may be supported by a single rear axle chassis.

In some embodiments, aerial ladder assembly 30 is extendable and includes a plurality of sections that may be actuated between an extended configuration and a retracted configuration. By way of example, aerial ladder assembly 30 may include multiple, nesting sections that telescope with respect to one another. In the extended configuration (e.g., deployed position, use position, etc.), the aerial ladder assembly 30 is lengthened, and the second end 33 is extended away from the first end 32. In the retracted configuration (e.g., storage position, transport position, etc.), the aerial ladder assembly 30 is shortened to withdraw the second end 33 towards the first end 32.
The aerial ladder assembly 30 forms a cantilever structure. According to the exemplary embodiment shown in

In one embodiment, the aerial ladder assembly 30 is unsupported at the second end 33. The bending moments generated by the various loads imparted on the aerial ladder assembly 30 are smaller at second end 33 and larger at first end 32, where the aerial ladder assembly 30 is coupled to the turntable 34 and to the hydraulic cylinders 36. According to an exemplary embodiment, base rails 46 include two tubular elements (e.g., first member 54 and second member 56, etc.) to carry the increased bending moment experienced by first zone 80 of aerial ladder assembly 30. Aerial ladder assembly 30 having base rails 46 that include a single tubular element (e.g., only first member 54, etc.) along second zone 82 has an increased strength-to-weight ratio.

According to an exemplary embodiment, brace 68 facilitates manufacturing aerial ladder assembly 30. By way of example, the brace 68 may be used in the manufacturing process as a fixture to position the first member 54 and second member 56 relative to one other. In an exemplary embodiment, the first section 54a and the second section 54b of first member 54 are positioned against the top plate 70 and the side leg 72 of the brace 68. The first section 54a and the second section 54b of first member 54 may then be coupled (e.g., welded, etc.) together and/or coupled to the brace 68. The first section 56a and the second section 56b of second member 56 may then be positioned against the side walls 64 of the first section 54a and the second section 54b of first member 54 and against the top plate 70 of the brace 68. The first section 56a and the second section 56b of second member 56 may then be at least one of coupled together, coupled to the brace 68, and coupled to the first member 54.
The brace 68 may be coupled to the first section 54a and the second section 54b of first member 54 with a weld along a distal edge 76 of the side leg 72. The weld may be continuous and extend along the length of the brace 68 or may include a plurality of intermittent welds (e.g., skip welds, etc.). According to an exemplary embodiment, the brace 68 is coupled to the first section 56a and the second section 56b of second member 56 along the distal edge 74 of the top plate 70. The weld may be continuous and extend along the length of the brace 68 or may include a plurality of intermittent welds (e.g., skip welds, etc.).

According to an exemplary embodiment, aerial ladder assembly 30 includes lacing members 50 and the lacing members 52 that are manufactured from thin-walled tubular members. Such an aerial ladder assembly 30 may have a reduced overall weight. In one embodiment, the arrangement of the various components of aerial ladder assembly 30 facilitate such construction without sacrificing load, vertical extension, or horizontal reach ratings. The lacing members 50 and the lacing members 52 may have a similar cross-sectional shape or may have different cross-sectional shapes. According to an exemplary embodiment, lacing members 50 are circular tubes and lacing members 52 are circular tubes. In other embodiments, the lacing members 50 and lacing members 52 may be otherwise shaped. By way of example, the lacing members 50 and the lacing members 52 may be tubes with a rectangular or hexagonal cross-sectional shape. In still other embodiments, the lacing members may be other structural members (e.g., angles, channels, rods, etc.). The size and/or shape of the lacing members 50 and the lacing members 52 may vary along the length of the aerial ladder assembly 30.
Referring still to the exemplary embodiment shown in
According to an exemplary embodiment, gusset 90 is a continuous body extending from base rail 46 upward into engagement with lacing members 50. As shown in
As shown in
The gusset 90 is coupled to the lacing members 50 with welds 104 and welds 106. In one embodiment, welds 104 and welds 106 continue along a first side of the gusset 90, around a corner 100 of gusset 90, and along an opposing second side of the gusset 90. In some embodiments, welds 104 and 106 may not extend around the corners 100 but may instead comprise separate welds formed on either side of the gusset 90. In one embodiment, the gusset 90 defines a single unitary body that extends from upper edge 92, through outer surface of the lacing members 50 (e.g., into the slot 98, etc.), and to a concealed portion 103 within the lacing member 50. Gusset 90 further extends downward from concealed portion 103 to base rail 46. In one embodiment, the single unitary body defines a continuous load path between the various components of aerial ladder assembly 30. Gusset 90 also reduces stress concentrations within the joint 88. The continuous extension of gusset 90 from upper edge 92 to concealed portion 103 also improves the likelihood that corners 100 will remain intact during a welding operation (e.g., to reduce the amount of corner 100 that is melted and assumed into the weld bead, etc.). A relatively smooth transition is therefore maintained between the upper edge 92 and the lacing members 50 and between the sides 96 and the lacing members 50, reducing the stress concentrations that may otherwise be formed between the lacing members 50 and the gusset 90. Such a reduction in stress concentrations facilitates a reduction in the weight of various components (e.g., lacing members 50, base rails 46, etc.), thereby reducing the weight of aerial ladder assembly 30.
The lacing members 50 and the gusset 90 are coupled to the base rail 46 with a weld 108. Weld 108 extends around the base of the joint 88, coupling the ends 51 of the lacing members 50 and the lower edge 94 of gusset 90 to the base rail 46. The weld 108 may couple the ends 51 of the lacing members 50 and the lower edge 94 to a brace 68 or directly to the top wall 60 of the first member 54 and/or the second member 56.
Because the gusset 90 passes through the lacing members 50 via the slots 98, stresses (e.g., sheer stresses, bending stresses, etc.) at the joint 88 can flow through the gusset 90 and directly into the base rail 46 instead of passing through the ends 51 of the lacing members 50. Aerial ladder assembly 30 may thereby include smaller lacing members 50 (e.g., smaller in diameter, smaller in wall thickness, etc.) than truss members having gussets 90 that do not pass through lacing members 50 or extend downward to base rail 46.
The configuration of the lacing members 50 and the gussets 90 also aids in the manufacturing of truss members 40 and the structural integrity of the joints 88. The slots 98 position the gusset 90 relative to the lacing members 50 along a preferred vertical plane (e.g., a vertical plane passing through the neutral axis of the lacing members 50, etc.). The slots 98 allow the gusset 90 to be accurately positioned relative to lacing members 50 without the use of an additional fixture. The slots 98 thereby reduce the risk that the gussets 90 will be welded in a skewed orientation (e.g., angled in a lateral direction, etc.).
Referring to the exemplary embodiment shown in
In an exemplary embodiment, the rungs 42 are thin-walled, tubular members thereby reducing the weight of the aerial ladder assembly 30. Rungs 42 may have a cross-sectional shape (e.g., round, elliptical, D-shaped, etc.) that facilitates the engagement thereof (e.g., grasping, stepping, etc.) by a fire fighter or a person being aided by the fire fighter. Rung supports 44 strengthen aerial ladder assembly 30, according to an exemplary embodiment. In one embodiment, rung supports 44 are coupled to rungs 42. Rungs 42 and rung supports 44 may define a plurality of braces (e.g., K-braces, etc.) that couple the truss members 40 together. The rung supports 44 are a V-shaped members that are coupled to the rungs 42 at a point between the two truss members 40. In an exemplary embodiment, the rung supports 44 are positioned rearward of (e.g., toward the first end 32 relative to, etc.) the rungs 42. The rung supports 44 include a pair of arms 110 extending between the rungs 42 and base rails 46. In one embodiment, the arms 110 are connected by a transition portion 112 that is coupled (e.g., welded, etc.) to the rung 42. In other embodiments, the rung supports 44 may not include the transition portions 112, and the arms 110 may be separate members that are coupled directly to the rungs 42. As shown in
In an exemplary embodiment, rung supports 44 are formed from a plate with one or more bending operations. As shown in

According to an exemplary embodiment, the ladder assembly includes base rails that are positioned such that loading imparted by the lacing members and that rungs is directed into corners of the base rails. The ladder assembly may also include slide pads shaped to receive the base rails (e.g., corners of the base rails, etc.) such that stresses transferred between ladder sections also flow through the corners of the base rails. In one embodiment, positioning and configuring the base rails, slide pads, lacing members, and rungs to direct loading through the corners of the base rails reduces weight, improves strength, and enhances the horizontal reach of the ladder assembly.
