FS 800
The FS 800 is a new generation longwall shearer, which was developed as a result of a combination of experience, advanced technical solutions, modern technologies and the highest quality materials.
Through the modular structure, the transport dimensions have been minimised, but this did not reduce the enormous capabilities of the shearer and its ability to work in high seams (cutting height up to 6 m). This machine is a shallow-web shearer, it works with armoured conveyors of 900m to 1,200m wide equipped with Eicotrack, Megatrac® or Gigatrack chainless haulage systems.
The haulage system structure allows to obtain various shearer heights without changing the hauling (carriage) bodies. The shearer loader has been designed in the Industry 4.0 standard, with functions of advanced parameter diagnostics and full monitoring of the machine operation on a mine surface. It is characterised by high efficiency, reliability, ease of use and operation. The FS 800 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.
