Roadheaders are mobile units used to dig tunnels and crush rocks with drill units, while removing rock fragments and other debris. The Group commenced the design and testing of prototype roadheaders in 2010, and currently have five prototype models that are generally classified into light-duty, medium-duty and heavy-duty, depending on cutting power. Our roadheaders are expected to operate under diverse mining conditions and be used in other construction applications, such as railway, roadway, subway and other construction settings.
