Cat® customized systems for longwall mining range from hydraulic roof supports and automated plow systems to shearers, face conveyors and roof support carriers.

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.

360VPTGH1600 Automated Plow System Medium to extremely hard coal
360VPTGH800 - Plow System Soft - hard coal
360VPTGH800B Automated Plow System Soft-hard Coal
360VPTRHH800 - Plow System Soft - hard coal

Roof Supports

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.
