We deliver your system of choice — from low to high seam heights, for the longest longwalls and highest production demands.
The quality and reliability of the automation system are key to the success of a longwall mining operation. Caterpillar is the only manufacturer able to provide a complete modular family of powerful controllers that integrate fully with Cat longwall equipment. The Cat PMC® family of Programmable Mining Controls offers one-stop shopping for all the controls, sensors and components a successful longwall system needs. There are no interfacing problems and products are customized to meet your needs.
The shearer is the heart of your longwall operation, working around the clock to cut away the face and keep the whole system productive. High installed power and machine mass for the toughest cutting conditions
Redundancy and high factors of safety in the design of the machine ensure maximum reliability
We offer a number of shearer models to suit seams ranging from 1.6 to 5.5 m (63 to 217 in).
For small and medium seams, a plow system can be less expensive and more productive than a shearer. Cat plows offer record-setting production in a compact, durable frame. With unmatched power and precise control systems, these machines are a cost-effective alternative for many mines. In coal seam heights below 1.8 m (71 in), the plow is more productive than a shearer.
Caterpillar offers plows for seams ranging from 0.6 to 2.3 m (23.6 to 90.5 in).
