First shield tunneling machine of Luoyang finished production

In June, the first shield tunneling machine of Luoyang - "Mudan" has been finished production, it's for Luoyang's subway construction, also fills up the blank space of Luoyang rail transit high-end euipment manufacturing.

Underground spaces are used for subway, railways, underground rivers, new physical distribution systems, garbage incineration facilities as well as energy-related facilities. The technology that is indispensable for creating these underground spaces is the technology of shield tunneling machines or tunneling shield.

During shield tunneling machine projects, a breakdown will result in costly repairs and long-time delay. Its components will operate in harsh conditions–dirty, corrosive environments with heavy loads. So the runneling shield machines require the most reliable components, especially the shield machine main bearings.

The main bearings of shield runneling machines should be built to withstand huge loads as cutter heads bore into solid rock. Usually the main bearings are heavy-duty, three row roller slewing bearings, structure and design will be designed and manufactured according to each application.

A qualified tunnel boring machine main bearing should be able to improve machine reliability, extend machine lifecycles and reduce maintenance, BRS-RIGIA Bearing is making an effort to achieve improvements in this area.
