Caterpillar is the global market leader and supplier of complete longwall systems. All over the world, our equipment and systems are meeting the demands of underground mining under the most stringent conditions. Adapted to the mining challenges faced by our customers today, Cat customized systems range from hydraulic roof supports, automated plow systems, shearers, face conveyors and drive systems to automation and roof support carriers.Caterpillar delivers your system of choice, from low to high seam heights, for the longest longwalls and highest production demands.
Armored Face Conveyors
Maximum productivity in the longwall is possible only if the conveyor technology can keep pace with the output of the mining machines. Cat® Armored Face Conveyors (AFCs) keep your production moving – delivering maximum capacity, high drive power, high availability and reliability.We take available space and desired production capacity into account when designing a complete, customized Cat conveyor system for your operation. Whether you want to build a 500-meter (1,640-foot) longwall, or mine different seam heights, Caterpillar supplies a perfect-fit solution – from AFC, to main and tail drives, to chain and entry conveyor systems.

Plow systems from Caterpillar make the plow the mining system of choice for low and medium seams under 1.8 m (5.9 ft). With features offered only by Caterpillar, our plow systems exceed the production performance of shearers and offer future-oriented solutions for hard-coal mining.
Steep grades, very thick and very thin seams, unstable roofs and massive sandstone plates, soft ground and geological faults. These varying conditions require a high level of adaptation to specific requirements. Cat® Roof Supports are world-renowned for their reliability under the most extreme conditions. With superior availability and unparalleled quality in design and production, our roof supports set the standard in longwall mining.
