Traffic poles are used to carry the traffic signals which controls the flow of vehicles traffic in roads and at intersections & junction points. It consists of a vertical shaft and cantilever arm whose length varies from 3 to 14 m depending on the road design and traffic requirements. Shape: Traffic Poles are usually of heights from 6 up to 8m having one or more cantilever arm which extends from 3 up to 14 m. Arms are tilted vertically with suitable angle from 2 up to 5 degree and per-cambered to compensate for the vertical deflection due to the self weight of arm & traffic signals. Pole shaft and cantilever arms with length up to 14 meters are made from one segment and having polygonal or conical shape with dimensions complying with the design structural analysis, international standards requirements, and as per customer requirements. Shafts and arms are made from steel sheet folded to the required shape and welded longitudinally by automatic arc welding machine. Base plate is square or rectangle in shape with holes suitable for the required anchor bolts. Dimensions of the base plate given in our drawings are complying with design analysis. Base plate is welded to the bottom of the shaft by double fillet weld, according to International standards. Base plate will be open in the centre to allow the cables in. Traffic signals are attached to the cantilever arms at specified location based on the road layout by clamping system (supplied by the traffic signal suppliers). Anchor bolts used to fix the base plate to the concrete foundation are supplied with the required nuts and washers and having the size and dimension as per the structural analysis. Door opening size and location is as per the customer requirements and its complying with the dimensions of the cut-out. Door opening is reinforced to maintain the shaft strength; in addition, a rubber gasket is fixed around the door frame for weatherproofing. Door cover is fixed to pole shaft by using a stainless steel Chain or Hinges. An Earthing lug is welded inside the shaft at the door opening level and equipped with the required bolts, nuts and washers for earthing. Straightness, tolerances and plumbness of the pole are maintained within permissible limits according to international standards. Design: Poles are designed according to AASHTO standard “ Standard Specifications for Structural Supports for Highway Signs, Luminaries and Traffic Signals “ and its latest revisions. Design wind speed is 160 Km/hr or as per the customer request multiplied by gust factor of 1.3 (Gust speed is 208 Km/ hr or as specified in the project specifications) Design of poles is performed utilizing Computer software to analyse the pole shaft, cantilever arm, base plate and anchor bolts. Material: Material used to fabricate the pole components will be in accordance of international standards and as per the project specifications. Finishing: Shaft, Base plate, cantilever Arms and other accessories are hot dip galvanised according to BS EN 1461 and its recent revisions, the minimum average coating thickness is according to BS EN 1461, or as per the customer requirements, but not more than 120 microns in any case. No welding, cutting or drilling is done after galvanising. The anchor bolts including nuts and washers are hot dip galvanised according to ASTM A 153.
