The roadheader is compact in structure, low in body, low in center of gravity, easy to operate and stable in operation. The cutting head is driven by an electric motor, and the horizontal or vertical axis can be arbitrarily chosen. The transverse cutting head can be arbitrarily chosen with two specifications, namely, Phi 750x1350, Phi 800x1500. The cutting speed is good when the coal or rock is cut below the medium hardness.
The difference between the roadheader and the traditional roadheader is that the cutting arm is composed of two sections. The two sections are connected by pins, each of which is controlled by two pairs of cylinders, and a pair of cylinders control its horizontal rotation.
Scope of application: For boom type roadheader machine, tunnel excavation for tunnel section 8-22m - coal roadway or semi coal roadway, also can be in the railway, highway, water conservancy project in use.
When working, the sizes and arms cooperate with each other, and the flexibility of the cutting arm is increased.
The cutting head is in the middle, and the distance between the cutting head and the shovel plate is greatly reduced.
The effect of auxiliary coal loading is good, and the contradiction of fast coal falling and slow coal loading is solved.
