REV: 04-29-25 LF All aerial device wiring shall be multi-conductor, copper 24 gauge (minimum), color-coded, with thermosetting cross-linked polyethylene insulation. All aerial device wiring shall be in pre- engineered harnesses with each circuit identified by number and color code. Harness connections shall be through locking, weatherproof, guided pin connectors. FRAME The trailer frame shall be of welded steel construction and gooseneck design. The gooseneck area shall be constructed using structural shapes and plate. This area of the trailer frame shall have a section modulus of 392 cubic inches and a resistant to bending moment of 14,090,000 inch pounds. The rearward portion of the trailer frame shall be constructed, using “C” channel and plate. The section of frame from the gooseneck to the axle shall have a section modulus of 233.5 cubic inches and a resistance to bending moment of 8,406,000 in lbs. The portion of the trailer frame rearward of the axle shall have a section modulus of 111.7 cubic inches and a resistance to bending moment of 4,021,200 in lbs. The gooseneck area shall be 45” wide and 15” deep. The “C” channel and plate portion of the frame shall be 34” wide and 13” deep. TRAILER FRAME PAINT The finished paint color shall be Job Color (to match primary chassis cab color) enamel, allowing easy touch-up after extended use. TRAILER FIFTH WHEEL ASSEMBLY The fifth wheel shall be a 1.25” diameter ball bearing, 3.875” x 34.00” diameter assembly, with the mounting plate bolted to the chassis. The longitudinal pivot point mounting shall utilize two (2) 2” diameter steel pins. A fifth wheel lockup system, utilizing four hydraulic cylinders, shall provide connectivity between the fifth wheel bearing assembly and the tiller trailer gooseneck to enhance stability, during aerial operations. After the stabilizers are in their proper load supporting position, an interlock system shall then provide control of the fifth wheel lockup cylinders. An additional interlock system shall prevent operation of the aerial ladder unless the stabilizers and fifth wheel lockup cylinders are properly deployed. After the aerial ladder is raised from the nested position, control of the fifth wheel lockup cylinders or stabilizers shall be prevented. The fifth wheel lockup system shall be part of the primary aerial hydraulic system. Systems which have the lockup cylinder connected to the fifth wheel bearing assembly during road travel, requiring constant exchange of oil between the front and rear cylinders, shall not be accepted. TRAILER WHEELBASE The trailer wheelbase shall be 346”. ATTY/AGR.2025.089/Fire Apparatus Solutions (Purchase of Spartan-LTC 105' TDA) (Page 121 of 150)
