• <br />Apparatus Dimensions <br />0 <br />• <br />The following table lists the dimensions for fire apparatus by class. The Department has four pumpers, <br />one pumper/ladder truck, an aerial platform and five ambulances. The dimensions in the table represent <br />the largest dimension of the trucks. <br />The pumpers and the aerial have bumpers that extend at least 18" beyond the front of the truck and <br />require additional clearance in a turn. Steep grades require special consideration. The angle of departure <br />is reduced by the length of the overhang (distance from the axle to the front and rear bumpers). <br />Pumper <br />Aerial Platform <br />Ambulance <br />fI <br />I P <br />A" <br />Overall Length <br />32' 48' <br />24' 6" <br />Overall Width <br />9' 9" <br />10' 0" <br />9' <br />Height <br />9' 6" <br />12' 0" <br />91411 <br />Wheelbase <br />16'9"= 201" <br />21'4"= 256" <br />14'2"= 170" <br />GV W <br />41,000 <br />69,100 <br />20,000 <br />Front Axle <br />16,500 <br />21,500 <br />8,000 <br />Rear Axle <br />24,000 <br />47,600 (tandem axle) <br />13,500 <br />Cram Angle <br />330 <br />340 <br />500 <br />S.A.E.
