In high and medium coal seams longwall shearers are successfully used throughout the world. However, in coal seams below 1.8 meters down to 0.6 meters height, where there are many of the best coal reserves worldwide, Cat® automated plow systems are outperforming shearers.
The proven and reliable plow technology has found its way into new coal mines around the world. The Cat gliding plows GH800, GH1600, and newly launched GH800B are successfully operated in Germany, USA, China, Kasakhstan, Czech Republic, Poland, and Russia.
Cat plow technology facilitates integrated, fast overload protection for the plow chain and all drive train components through special Cat gearboxes. Moreover the plow system can easily follow undulated seams because of the proven horizon control system.
