Abstract

Claims (20)

1 . A ladder assembly for a fire apparatus, the ladder assembly comprising:

a base rail including:

a first tubular member;

a second tubular member; and

a brace extending along (a) a horizontal wall of the first tubular member and the second tubular member and (b) a vertical wall of at least one of the first tubular member or the second tubular member;

a hand rail;

a first lacing member and a second lacing member extending between the base rail and the hand rail, both the first lacing member and the second lacing member engaging the base rail at an interface, each of the first lacing member and the second lacing member defining a slot along only a portion of a length thereof, each of the first lacing member and the second lacing member including an end that directly contacts the brace at the interface; and

a gusset having portions received by the slot of the first lacing member and the slot of the second lacing member, the gusset engaging the base rail to reinforce the interface.

2 . The ladder assembly of claim 1 , wherein the base rail, the first lacing member, the second lacing member, and the gusset are welded together at the interface.

3 . The ladder assembly of claim 1 , wherein (i) the first lacing member extends between the base rail and the hand rail at a first angle and (ii) the second lacing member extends between the base rail and the hand rail at a second angle that is offset from the first angle.

4 . The ladder assembly of claim 1 , wherein the end of the first lacing member is spaced from the end of the second lacing member such that a gap is defined therebetween, wherein a lower edge of the gusset is within the gap.

5 . The ladder assembly of claim 1 , wherein the gusset has (i) an upper edge that extends between the first lacing member and the second lacing member and (ii) a lower edge positioned along the brace that forms at least a portion of the interface.

6 . The ladder assembly of claim 1 , wherein the upper edge of the gusset is curved toward the interface.

7 . The ladder assembly of claim 1 , wherein the gusset include sides that extend between the upper edge and the lower edge thereof, and wherein the sides are received by the slot of the first lacing member and the second lacing member.

8 . The ladder assembly of claim 7 , wherein the sides are curved toward the interface.

9 . The ladder assembly of claim 7 , wherein the gusset is generally trapezoidal shaped.

10 . The ladder assembly of claim 1 , wherein the portions of the gusset received by the slot of the first lacing member and the slot of the second lacing member are concealed within the first lacing member and the second lacing member.

11 . The ladder assembly of claim 1 , wherein:

the first tubular member has a first length; and

the second tubular member has a second length less than the first length.
