FS 800

FS 800 is a new generation shearer loader, which was developed by combining the advanced technological solutions, expertise, modern technologies and the highest grade materials. Thanks to the modular design transport dimensions are minimised, which did not diminish the powerful capability of the shearer and the ability to work in high seams (mining height up to 6.0 m).

This shallow web shearer loader can operate with a face conveyor with a width of 900 to 1200 mm, equipped with a chainless haulage system type Eicotrack, Megatrac® or Gigatrack. The design of the feed system allows for different shearer heights without changing hauling frames. It is used for bidirectional niche-free coal mining and loading in a longwall system, with the strike of up to 35°, the dip up to 25°, the upwards up to 15° and downwards.

The shearer is designed in the e-mine standard, with the function of advanced diagnostic of parameters and full monitoring of the machine operation from the mine surface. It is characterised by high capacity, reliability and ease of maintenance and operation.

FS 800 can be delivered in the e-complex standard, with additional equipment to work in an automatic cycle.
