Product: Speed Camera Brackets
Application: Department of Transport and Main Roads
Sectors: Infrastructure; Government
Master Steel supplied the mounting brackets for the new Point to Point Speed Cameras of the Department of Transport and Main Roads in the South Coast Region. This project was initially a prototype however has now been successfully delivered with frequent collaboration between us and RoadTek. The cameras, which promote the safety of Queensland roads, are placed along strategic points along the Pacific Highway or M1.
The Camera Pivot Frames on the northbound and southbound lanes of Exit 35 and 57 are attached on the safety railings. The mounting bracket is made of Grade 250 steel plate and attached on the safety railings by M16 ChemSet anchors. A plate G250 steel extends from the base plate to hold both the support arm of the camera pivot and the brace bar. The Neoprene bush locked with M20 bolt and nut hold the support arm from below.
The support arm extends for 1040mm from the mounting bracket and is made with square hollow section steel. On either side are curved circular hollow sections C350LO, each with 120 diameter by 8mm flange plates where the cameras are attached with galvanised bolts.
The service access arm and brace bar features M10 steel rod hand grips and extends from the end of the support arm to the safety railing. It is padlocked according to the Department of Transport and Main Roads’ specifications. When in retracted position, the support arm is secured against the safety rail with lanyard and carabiner through the padlock.
The Type 2 P20 Camera Pivot Frames on the southbound lanes of Exit 66 are set the same way as those on Exits 35 and 57. However, for the northbound lanes, the pivot frames are configured differently as they are set flat on the balustrade. The bracket is Grade 250 steel plate attached with jacking nuts to achieve 1:40 rotation and M16 ChemSet anchors.
The support arm is 825mm long and turns 90 degrees downward for the 410mm extension. The end of the support arm also has a pair of curved circular hollow sections holding up the flange plates for the cameras. The service access arm extends from the top of the support arm down to the back of the mounting bracket and padlocked on the balustrade.
All structural fabrications are carried out by our Main Roads registered boilermakers. All weld is compliant to AS/NZS 1554.1, which defines the requirements for the welding of steel structures with steel plates, sheets, or sections such as hollow sections and built up sections.
The hot rolled bars and sections are Grade 300 in accordance with Australia and New Zealand Standards. Grade 300 bars and sections are typically used in general fabrication and as structural steel members. All steelworks are hot dipped galvanised following AS/NZS 4680, which specifies the requirements for zinc coatings on fabricated ferrous components, such as structural steel, steel reinforcements, and steel sheet fabrications, among others.
All welds are minimum 6mm Continuous Fillet Weld, which means that the weld should span the entire length of the joint. Butt welds are full penetration welds compliant with AS 1554.1, while all hollow sections are full penetration bevel butt welded at connections.
