Cat Automated Plow Systems

Today, Caterpillar is the market leader in the field of fully integrated and automated plow systems. Sophisticated Cat plow systems today operate fully automatically with drive powers of up to 2 x 800 kW and speeds of up to 3.6 m per second. Seam thicknesses between 0.6 and 2.3 meters (23.6 and 90.5 in) can be efficiently mined with this method. Plowing is the preferred longwall mining technique for seams below 1.8 m (71 in). The depth of cut is set via the electro-hydraulic support control system in connection with stroke sensors in the shifting rams of the roof support.
