| Breakthrough with an Aker Wirth roadheader T3.20  2nd November 2010 - Last week an important milestone at the Airport Link and Northern Busway (Windsor to Kedron) project is reached. An Aker Wirth roadheader T3.20 broke through in the 490 metre long Busway tunnel at Lutwyche. Four heavy-duty Aker Wirth T3.20 roadheaders, originally manufactured in Germany, are once more excavating in the Brisbane area, after successful completion of the Clem Jones Tunnel. All four machines are equipped with 300 kW powered inline cutterheads and have an operating weight of more than 130 t. The roadheaders are operating in different sections of the Airport Link tunnel project, successfully facing the specific challenges of each section. With local support as and when required, and a full complement of consignment stock on site in Brisbane Aker Wirth ensure a smoothly work of the machines with extreme low maintenance time. The Airport Link tunnelling project is an example of Aker Wirth's competence in hard rock tunnelling.The Airport Link is a 6.7km toll road, mainly underground, connecting the Clem 7 Tunnel, Inner City Bypass and local road network at Bowen Hills, to the northern arterials of Gympie Road and Stafford Road at Kedron, Sandgate Road and the East West Arterial leading to the airport. write your comments about the article :: © 2011 Construction News :: home page |
