1101. 05(a) 1101. 05(b)

• Galvanize poles and base plates as specified in Section 1101.02(b)3.

• Grind or bevel mating edges of multi -section poles to avoid binding during section assembly.

• Do not use transverse welds.

• Provide base plates with a minimum thickness of 3- inch unless otherwise approved.

• Provide bottom shaft sections with an 0.625 inch minimum thickness.

• Provide a complete joint penetration weld for the connection of the shaft to the base plate according to the AASHTO LRFD Specifications Table 11 .9.3.1 -1 Section 4.4.

• Provide complete- penetration longitudinal welds in the slip- joint area (1.5 times the inside diameter of the exposed end of the female section) plus 6 inches beyond, for the female section only. Provide 6- inch complete penetration longitudinal wel ds at the base plate connection.

• Join each pole section by telescoping the individual sections. Overlap a minimum of 6 inches and maximum of 12 inches . Do not field weld.

• Mark corresponding pole sections for field mating and assembly.

• Mark the inner telescoping section to show the minimum required telescoping length.

• Clearly mark and identify each pole base plate for matching to the corresponding anchor bolt assembly, to ensure proper fit in the erection of each pole.

• Permanently inscribe each pole with manufacturing identification and reordering information or show on a nameplate attached to the pole.

• Provide four -conductor copper No. 10 AWG minimum, 600 V, electrical cable, of the type and length required, with a watertight electrical plug and receptacle suitable for use.

• Provide a matching watertight power receptacle having sufficient cord length to be brought outside for energizing the lowered luminaire mounting ring and the electrical power drive.

• Provide a low resistance grounding lug at the top of the pole for grounding the lightning rod to the pole shaft.

• Provide stainless steel hardware; such as nuts, bolts, screws, and washers.

(b)Head Frame Assembly. Provide a head frame assembly with each high-mast pole, to support the

luminaire ring with its required number of luminaires, and as follows:

• Mount pulleys and mechanisms on the head- frame assembly; cover with a protective non- corrosive housing.

• Make necessary cable openings as small as practical to prevent the entry of birds.

• Provide a housing that can be easily removed from the head- frame assembly for servicing of pulleys and other mechanisms.

• Provide a 24- inch, nickel -tip copper lightning rod on each pole, extending not less than 20 inches above the head- frame cover and located on or near the pole centerline. 1101. 05(b) 1101. 05(e) • Ground the lightning rod to a grounding lug at the pole top, using No. 1/0 AWG b
