Roadheaders

KSP-22 roadheader – is the smallest and most lightweight in the product line of Perspective Technologies, LLC. It is characterized by high power and high productivity and is suitable for most types of low-height workings of any cross-section shape (arched, trapezoidal, rectangular and round). The roadheader can work on layers containing coal, mudstone and shale with UCS of up to 70 MPa and abrasiveness of up to 15 mg in mines hazardous for gas (methane) and coal dust.

STRUCTURAL FEATURES

  • An extendable actuator with a closed wedge-type guide circuit allows the cutting head to be drilled into the rock without moving the machine.
  • The feeder is given the function of a front support. In combination with the rear hydraulic supports, this provides sufficient stability of the machine when cutting rocks.
  • The hydraulic drive of the gathering arms and stroke allows to operate the roadheader in conditions of high water content.
  • Crawler tracks which are independently operated to give maximum machine maneuverability.
  • A number of versions of the roadheader provides the ability to move the destroyed rock mass from the face with various transportation flowcharts.

The PK-8MA roadheader is designed for carrying out preparatory workings and treatment chambers during underground mining of potash ores with a cutting resistance from 4.0 to 4.5 kN/m2 in mines hazardous for methane gas.

The roadheader can operate in one of two mutually exclusive modes - semi-automatic and manual control.

The roadheader is available in two versions - with a cutting boom with a diameter of 3.0 and 3.2 m.
