Abstract
An integral tank frame for an emergency response vehicle is provided. The integral tank frame includes a tank mounted within an envelope of space of a ladder frame. The ladder frame has side rails that support the tank on either side thereof. The tank can be mounted to the side rails such that it extends across the top of the side rails, interior to the side rails, or a combination thereof.
Claims16
A frame for an emergency vehicle, comprising:
- a pair of longitudinally extending side rails;
- a plurality of lateral supports extending transversely between the pair of longitudinally extending side rails to form a ladder shaped configuration, wherein an envelope of space is defined between the of longitudinally extending side rails and between an adjacent pair of the plurality of lateral supports;
- a tank mounted within the envelope of space, the tank configured to carry a flame retardant fluid;
- and
- wherein the tank includes integral side rail portions, the integral side rail portions positioned on opposing sides of the tank and configured for mechanical attachment to the pair of longitudinally extending side rails.
