coal mining machine

Main feature:

1: compact structure , body is low , with a low center of of gravity , easy to operate , and operate steadily,. Cutting head is driven by electric motor , and it can be horizontal or vertical axle form arbitrary . Horizontal axle cutter head size can be Φ750x1350 and Φ800x1500 such two standards , it has good cutting speed when cut medium hard coal rock .

2: The difference between Our road header and traditional ones lies in : cutting arm adpots two joints from , and the two joints are connected by axis pin , and two cylinders control it go up and down , one cylinder control it turn horizontal .

Our road header has such following advantages

1: Because the arm is narrow , the driver's vision is wide , big and small arms coordinate with each other when working , it Increase the flexibility of cutting arm .

2: When cutting forearm bending , the distance between cutting head and apron is 180mm as cutter head is in the middle position , but when it is at two sides position , the distance is only 100mm , so it reduce the distance between cutting head and apron greatly .

3: Because the rotation of cutting head , the coal is retrojected to apron , assistant coaling result is better , it resolve conflict between coal falling fast and coaling slow .

Application

Cantilever selective roadheader is suitable to tunneling in drift section of 8-22m2 , or Half coal crag tunnel .

in accordance with international and local regulations. All our roadheaders are available with a longitudinal or transversal cutterhead, whichever is best suited for your project's geological conditions.
