Coal Mining Machine (EBH 120 Roadheader)

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 transversal or longitudinal axis form arbitrary. Transversal axle cutter head size can be Φ 750x1350 and Φ 800x1500 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 semi-coal road tunneling. It is a piece of excavating equipment consisting of a boom-mounted cutting head, a loading device usually involving a conveyor, and a crawler travelling track to move the entire machine forward into the rock face.
