FS 300
The FS 300 longwall shearer has been developed as a combination of advanced technological and technical solutions with the highest quality materials. This machine is characterised by high efficiency, reliability, ease of use and operation.
The shearer’s design has been adapted to work with various types of longwall armoured conveyors with width of 750 to 900mm, equipped with Eicotrack (125, 126 mm) or Megatrack ® (147 mm) chainless haulage systems. It is also possible to change the height while maintaining a significant ground clearance under the shearer.
The shearer loader has been designed in the Industry 4.0 standard, therefore it is provided with functions of advanced parameter diagnostics and full monitoring of the machine operation on a mine surface. The FS 300 can be provided in the along with additional equipment enabling operation in an automatic or remote cycle. The shearer is adapted to work in underground mines of class “a”, “b”, “c” methane explosion hazard and class “A” and “B” coal dust explosion hazard.
FAMUR also offers the KGE-710FM and KSW-880EU electric shearers. These are older models that can successfully replace the FS 300 shearer. Upon individual orders, we are able to deliver both the KGE-710FM and the KSW-880EU shearer, as well as relevant spare parts.
