Roadheaders Building the tunnels and stations

Our roadheader fleet is essential in this design, carving out a space for the 19m wide platform before it is reinforced with a combination of sprayed concrete, rock bolts and a final concrete liner. The roadheaders will advance at approximately two metres per day.

Industry • The history of roadheaders

A roadheader is a machine intended for the excavation of underground headings, i.e. a machine which performs several functions within that process. A heading is an excavation characterised by considerable length in relation to its cross-section. New tunnels were built over 100 years later. The heading machine was also forgotten for a long time.
