Custom Fire Apparatus, Inc. <br />HORIZONTAL REAR HANDRAIL, BELOW HOSE BED <br />Matching material tubular railing is to be provided, horizontally on rear body vertical panel below the <br />hose bed gratings. Railing is to be as wide as is possible, without causing interference with optionally <br />specified rear inlets/outlets or step assemblies. <br />UNDER BODY STAINLESS STEEL SUB -FRAME <br />An apparatus body sub frame is to be furnished, completely independent of the assembled apparatus body <br />fabrications, bolted to and easily removable from the body module. The apparatus body sub frame, <br />including a forward yoke assembly with torsional suspension, transverse under -tank -cradle supports, and <br />a rigid cantilevered rear platform, are to be constructed of rectangular heavy wall type 304 stainless steel <br />welded tubing. Overall sub frame design will provide a corrosion -free structural under body "platform" <br />onto which the compartmented apparatus body is to be bolted to and easily removable from. <br />FORWARD BODY SUB -FRAME <br />A forward sub frame "yoke" is to be furnished, with upper level horizontal transverse cross -members <br />supporting the water tank cradle, and lower level outboard and rearward horizontal members providing <br />under -compartment -floor support of all side and rear compartments. Sub frame vertical tubular structures <br />are to be no more than 1" from chassis frame webs, so as to allow for maximum interior depth of all side <br />compartments. Four (4) bolt -through rubber cushion "vibration and torsion isolators" are to be provided, <br />two (2) per side. Isolators are to bolt to .312" longitudinal yoke structures, and chassis frame web .312" <br />angle brackets, the assembly of which allows for unlimited twisting -moment of the chassis frame rails, <br />independent of the body sub frame. Lower level horizontal under -floor supports are to allow for <br />individual compartment floor load rating in excess of 800 pounds per compartment (as determined by <br />body construction material), without deformation of the floor material. <br />REARWARD BODY SUB -FRAME <br />A "cantilevered" rear under body and tailboard sub -frame platform will be furnished, with transverse and <br />longitudinal tubular stainless structures welded to .75" x 8" glove plate frame drops which are bolted to <br />the side web of rear most chassis frame rails. Glove plates are to be located immediately rearward of the <br />chassis rear axle suspension, and are to include integral bottom 3" diameter closed tow eyes. A bolt -on <br />tubular structure is to be provided, spanning between the glove/tow plates, with its removal allowing for <br />the entire body sub frame (with compartmented body attached) to be lifted vertically from the chassis. <br />TAILBOARD SUB -FRAME <br />The specified cantilevered rear under body sub -frame platform shall continue rearward, beyond the rear <br />body corners and rear face of body, providing rigid support of the specified apparatus rear <br />tailboard/bumper. Tailboard/bumper understructure is to consist of the same heavy tubular stainless steel, <br />barrier isolated from any dissimilar metals, its design allowing for the tailboard fabrication to be <br />positioned away from and independent of the body fabrications. <br />BODY SUB -FRAME MOUNTING TO CHASSIS <br />07/26/22 <br />- 110 - <br />
