EBH120 Type Roadheader

EBH120 Type Roadheader

It is a cantilever type of local section boring machine,suitable for 8-22m2 coal roadway or half coal roadway,as well as railways,highways and other roadway excavation roadway,for water conservancy projects and other tunnels.The main features of the machine are:compact structure,short fuselage,low center of gravity,easy to operate,stable operation.The cutting head can be driven by a hydraulic motor or a motor,and the horizontal or vertical axis can be selected arbitrarily.The horizontal cutting head may choose theø750x1350,ø800x1400 two kinds of specifications,in the coal rock cutting hardness moderate below has the better cutting speed.The main difference between the tunneling machine and the traditional roadheader is that the cutting arm is composed of two segments,two segments are connected by a pin shaft,two pairs of cylinders control the Take-off and landing,and a pair of cylinders control the horizontal rotation.
