1. A fire apparatus, comprising:
- 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 coupled to the chassis and defining a longitudinal direction, the aerial ladder assembly comprising;
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, wherein the first lacing member and the second lacing member each include an end that extends downward and directly contacts the base rail at an interface; and
a gusset including a flat plate having an upper edge and a lower edge and positioned to reinforce the interface, wherein the upper edge of the gusset extends from the first lacing member to the second lacing member, and wherein the lower edge of the gusset is positioned along the base rail and forms at least a portion of the interface,wherein the first lacing member and the second lacing member each define a slot that receives the gusset, the gusset extending through the first lacing member and the second lacing member to the base rail, and wherein the base rail, the first lacing member, the second lacing member, and the gusset are welded together at the interface.
