FS 300

FS 300 longwall shearer is a combination of advanced technical solutions, high technology and the highest class materials, which makes the machine high efficient and reliable, easy in maintenance and simple in operation.

The longwall shearer design is compatible with different types of armoured face conveyors with chainless haulage systems Eicotrack (125, 126 mm) or Megatrack (147 mm) type. It also enables the change of the shearers height while maintaining a significant clearance under the machine.

The shearer is made in the e-mine standard with advanced diagnosis of machine functions and parameters, as well as full monitoring, that can be transmitted to the surface.

The FS 300 shearer can be supplied in the e-longwall standard with equipment operating in automatic mode.

  • high productivity resulting from high installed power and high clearance under the shearer
  • modular design enabling limitation of maximal transportation dimension to 2.6 m
  • comfort of operation (from the gob side)
  • 3rd generation control system in the e-longwall system standard
  • modular design of electrical equipment
  • innovative safety solutions
