EBH120 Cantilever Roadheader

1: High Efficiency Underground Coal Roadheader 2: Cutting Hardness f 8-10 3: Hydraulic system ,strong ability of cutting

EBH120 Underground Coal Roadheader Main feature :

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 transversal or longitudinal axis  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 .

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  roadheader is suitable to tunneling in drift section of 8-22m2 , or semi-coal road tunneling . it can also be used in railway ,highway and river construction tunnel .
