Custom Fire Apparatus, Inc. <br />bearing surfaces, and activation switch conveniently located on the passenger side pump control panel. <br />The scissors mechanism is to consist of a dual set of parallel .5" x 2" aluminum flat bar links with six (6) <br />bronze bushed pivot bearings, attached to the truss frame, the back wall of the cavity, and the hydraulic <br />cylinder telescoping rod. The truss frame shall have 1.5" diameter bottom pivot pins and cup style grease <br />able bearings which are bolted to the outboard bottom corners of the equipment rack cavity. <br />The hydraulic actuator and truss frame are to be recessed into a vertical cavity above the wheelwell <br />housing, provided with a fabricated job color painted body panel which completely covers the truss <br />frame, overlapping the forward and rearward outboard exterior side compartments. The body panel shall <br />be attached to, travel with, and be easily removable from the vertical truss frame. Attachment shall <br />incorporate horizontally adjustable stainless steel brackets and multiple aircraft style slotted cowl <br />fasteners. The painted body panel is to extend from the equipment rack's point of rotation to the top of <br />the side compartments, overlapping the cavity outboard corners. <br />A tubular ladder rack platform is to be permanently attached to the top of the truss frame actuator, and is <br />to be provided with dual (2) bolt -on ladder beam brackets with spring loaded chrome plated rotating <br />D-handle swing -away ladder rung clamps. The ladder beam brackets are to be positioned, one (1) ahead <br />of a ladder rung and one (1) behind a ladder rung, so as to prevent forward or rearward movement of the <br />nested extension and roof ladders. <br />Hydraulic ladder rack design must allow for opening and closing of passenger's side compartment doors <br />with ladder rack in the up and down positions. Center post truss frame's design must allow for <br />unobstructed access to the side and upper level compartments, with the equipment rack in its down <br />position, NOTE: Equipment racks that require apparatus body front and rear corner mounted swing -down <br />arms; therefore obstructing access to the side compartments with rack in "down" position, are not <br />acceptable. <br />A large flashing red indicator light is to be furnished on cab dashboard to indicate "ladder un nested". <br />Warning for the equipment rack being un-nested is to be integrated into the "Do Not Move Apparatus" <br />light located in driver's compartment. Where hinged compartment doors or other exterior side body <br />accessories interfere with the travel radius of the equipment rack, and interlock shall prohibit movement <br />of the rack until such accessory is secured. <br />Two (2) amber color LED warning lights are to be furnished, mounted forward and aft on the ladder rack, <br />so as to provide a visual emergency warning while the rack is in "down" position. In addition to the <br />warning lights, an audible alarm is to be provided, activated only while the rack is moving up or down. <br />An air cylinder operated spring -loaded mechanical "Ladder Rack Up Safety Lock" is to be furnished, <br />which automatically locks in the rack -up position and automatically retracts/disengages with activation <br />and normal operation of hydraulic actuator. <br />Ladder rack platform is to accommodate the optionally specified multi -section extension ladder and roof <br />ladder. <br />EQUIPMENT RACK BOXES <br />07/26/22 <br />- 117 - <br />
