P220 HEADER

The Type P220 Header is designed on the advanced designs embedded in the prototype P110 machine from which it differs in 1.5 to 2-fold capacity, capability to cut more hard rocks and to work larger cross-sectional areas in the faces and better reliability.

The Type P220 boom-type cutter header of the selective action is designed to carry out the powered cutting and loading of the rock mass when driving the arch-shaped, trapezoidal or rectangular workings of 90 to 30 square metres in cross-sectional area with the dip angle of ±12° in the coal or mixed faces at maximum rock hardness of 120 MPa (f=8) and abrasiveness up to 18 mg in gassy and dust-ignition hazardous mines.
