AERIAL LADDER FOR A FIRE APPARATUS

摘要

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.

1. An aerial ladder assembly for a fire apparatus, comprising:
a first truss member including 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, wherein the first truss member extends along a longitudinal direction; a second truss member including 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, wherein the second truss member extends along the longitudinal direction; and a plurality of rungs coupling the first truss member to the second truss member, the plurality of rungs extending across the longitudinal direction, wherein the first truss member and the second truss member define a first zone and a second zone separated by a transition, the first base rail and the second base rail having a first shape within the first zone and a second shape within the second zone.
