May 01, 2017· The roadheader, or header machine, has become a familiar piece of excavating equipment in civil tunnelling. The technology is actually younger than may be realised with the first roadheader patent being applied for by Dr Z Ajtay in Hungary in 1949 and developed as a remotely operated priapic miner for exploitation of small seams in coal mining.
The smallest roadheader we have has a loading width of 3.5 m, which can be customized smaller if the customer requires. Our most common roadheader used for tunneling – the MT 720 – has a 4.56-m wide loading table. For tunneling projects, the two big models MT 720 and MT520 represent about 90 percent of what we build.
Roadheaders were initially utilized in coal mining applications. The first use of a roadheader in a civil engineering project was the construction of the Melbourne Underground Rail Loop in the 1970s, where the machines enabled around 80% of excavation to be performed mechanically.
