Aluminum Light Pole Specifications
The 4-Bolt base flange for attachment to the foundation or to the transformer base shall be of cast Aluminum Alloy 356-T6. Base flange shall be joined to pole shaft by means of complete circumferential welds; externally at the top of flange and internally at bottom of shaft tube. Four anchor bolt covers of cast Aluminum Alloy 356-F with stainless steel hex head attaching screws shall be provided.
3-Bolt-Base
The 3-Bolt base flange shall be of cast Aluminum Alloy 356-T6 with spun aluminum base cover and stainless steel hex head attaching screws. Base flange shall be joined to pole shaft by means of complete circumferential welds; externally at the top of flange and internally at bottom of shaft tube.
Hinged Base
Hinged cast aluminum base flange of Alloy 356-T6 with 2-piece cast aluminum base cover and stainless steel hex head attaching screws. Base flange shall be joined to pole shaft by means of complete circumferential welds; externally at the top of flange and internally at bottom of shaft tube. The hinge mechanism is engaged by removal of the 2-piece cover and two front anchor bolt nuts.
Beehive Base
The Beehive cast aluminum transformer base shall be of Alloy 356-T6 with an aluminum door and stainless steel attaching screws. Base shall be joined to pole shaft by means of complete circumferential weld.
Direct Buried
Direct Buried aluminum poles are designed for embed installations. Poles with butt diameters of 6″ and larger shall be provided with an anti-rotational device by means of partial flattening the butt of the pole into an oval cross-section. A wiring provision will be provided 24″ below ground line. Soil conditions vary by site, therefore foundation requirements should be determined by a qualified Structural Engineer with knowledge of jobsite soil conditions.
Transformer Base (T-Base)
The T-Base shall be a casting of Aluminum Alloy 356-T6 with removable access door held in place with one stainless steel screw. The base shall be 17″ tall with an access door 11-3/4″ high, 9-1/4″ wide at the top and 9-3/4″ wide at the bottom. It shall connect to 1″ diameter anchorage. Three bases with bolt circles ranging from 10″ to 17-1/4″ can be used with shafts in size from 6″ to 10″ diameter (dependent on their proper application and specific loading restrictions). The bases shall meet 2009 AASHTO breakaway requirements. Four (4) 1″ diameter galvanized steel hex-head machine bolts with nuts and washers shall be supplied to attach the transformer bases to the base flange of the pole shaft. Eight (8) 1/2″ thick x 2-3/4″ diameter galvanized steel heavy washers shall be provided to properly distribute the bolt forces in the top and bottom flanges of the transformer base.
The 4-Bolt cast aluminum base flange shall be constructed of Alloy 356-T6 with aluminum snap-in bolt covers.
Hinged Base
The Hinged cast aluminum base flange shall be constructed of Alloy 356-T6 with three (3) stainless steel screws. Base flange shall be joined to pole shaft by means of complete circumferential welds; externally at the top of flange and internally at bottom of shaft tube. The Hinge mechanism is engaged by removal of the three (3) securing screws.
4″-5″ butt diameter poles shall feature a 2″ x 4″ handhole with curved lap style aluminum door and two (2) stainless steel self-tapping attaching screws. A grounding provision incorporating a tapped ¼”-20NC hole is provided opposite the handhole.
6″ Butt Diameter
6″ butt diameter poles shall feature a reinforced, 3″ x 5″ curved cast aluminum frame (Alloy 356-T6) with aluminum door and two (2) stainless steel hex head screws. A grounding provision incorporating a 3/8″ diameter hole is provided opposite the handhole.
7″+ Butt Diameters
7″ and larger butt diameter poles shall feature a reinforced, 4″ x 6″ curved cast aluminum frame (Alloy 356-T6) with aluminum door and two (2) stainless steel hex head screws. Reinforced frame will contain a tapped 3/8″-16NC grounding provision.
4″-5″ square poles shall feature a 2″ x 4″ handhole with square lap style aluminum door and two (2) Stainless Steel self-tapping attaching screws. A 1/4″-20NC grounding provision is provided opposite the handhole.
6″+ Base Squares
6″ and larger square poles shall feature a 3″ x 5″ handhole with square lap style aluminum door and two (2) Stainless Steel self-tapping attaching screws. A 1/4″-20NC grounding provision is provided opposite the handhole.
