Roadheader Machine,China Roadheader Machine manufacturer. Pull the operating stick forward to make the roadheader go forward, and pull it backward to make the machine go backward. 3. When turning a corner, pull both of the operating sticks simultaneously in the direction opposite with the turning direction of the machine.
A major strength of roadheaders for mining is the fact that also develops and manufactures productive and durable cutting tools for the machines. Better tools and less frequent tool changes translates to direct improvements in productivity, cost-per-tonne efficiency, maintenance costs and energy efficiency.
