The standards as shown in this section are design to withstand dead loads and theoretical dynamic loads developed by variable wind speeds as charted with an appropriate gust factor under the following conditions: The luminaire(s) and/or mounting bracket(s) center of gravity is assumed to be located at the pole top for all designs. For purposes of design, effective projected area (EPA) is considered to be the product of the actual projected area and the drag coefficient. The listed weights include luminaire(s) and/or mounting bracket(s). The wind velocities are based on 10 mph increments from 80 mph through 100 mph. Standards to be located in areas of known abnormal conditions require special consideration. For example: coastal areas, airports and areas of special winds such as the Chinook type along the eastern slope of the Rocky Mountains.
The pole shall be a one section design fabricated from standard 11 gauge (0.125”), 7 gauge (0.188”) or 3 gauge (0.250”) aluminum. The shaft will be extruded from all new 6063 series alloy aluminum tubing. Heat treated to produce a T6 Temper. Shafts shall be supplied with a top closure when the shafts are to be drilled for side mounting of luminaires.
The reinforcing handhole rim consists of a nominal 3’’ x 5’’ rectangular shaped tubing material. It is provided with a cover plate, attachment bar and machine screw.
Shaft is furnished with ground bolt located inside pole on wall opposite hand hole and a ground bolt will be welded.
Anchor Bolts are hot dipped galvanized in accordance to ASTM-A-153. Anchor bolts are fabricated from hot rolled steel bar with a minimum yield strength of 50,000 psi. Four anchor bolts are provided per pole. Each anchor bolt is furnished with two hex nuts and two flat washers and one lock washer.
ANCHOR BASE PLATE:
The anchor base is cast from A356 alloy aluminum, heat treated to a T6 condition. The base telescopes the pole shaft and is circumferentially welded top and bottom.
POLE BASE COVER:
The pole base cover is spun aluminum construction. The covers are two piece assemblies secured together with two fasteners.
Each pole will be provided with removable top cap with drill-mount poles or 2-3/8” x 5” pole top tenons. (Optional other sizes available)
All pole, mounting brackets and platforms shall be polished with fi ne grain aluminum oxide cloths, primer, factory painted and polyester powder coated.
