In early September 2019, Caterpillar showcased a number of its new longwall mining products and solutions at the international Trade Fair for Mining, Power Generation and Metallurgy in Katowice, Poland.

Caterpillar designs and manufactures complete longwall systems customised to optimise performance in specific applications. The Katowice exhibit presented new longwall components, such as the Cat EL1000 Shearer, designed for low to mid seam heights. This latest addition to the successful range of Cat shearers covers seam heights from 1.6 to 3.2 meters.

The recently introduced Cat PF HD Line Pan for armoured face conveyors is especially designed for heavy-duty longwall applications with demanding conditions. The new pan is the most robust and reliable Cat line pan, lasting up to two times the life of corresponding PF5 and PF6 pans.

The exhibit also previewed the Cat HTD4100 High Torque Drive System for longwall armoured face conveyors. The drive enables a higher level of automation for enhanced speed and torque control and real-time monitoring, and its modular design simplifies installation and maintenance. The converter-controlled torque motor offers fast response and precise control to reduce conveyor chain wear and failures.

Caterpillar previewed its next generation roof support control, PMC-R 2.0. It is the successor to the very successful Cat PMC-R control unit. The new roof support control unit is designed to meet the automation needs of modern, high-performance longwall operations. Advanced microcontroller technology with increased computing power and enhanced communication capabilities offers improved functionality to control roof supports in a self-advancing longwall system. The new controller also features enhanced serviceability.

Caterpillar and Cat dealers have created a one-of-a-kind, on-site support network for delivering expert service, integrated solutions, after-sales support, fast and efficient parts fulfillment, world-class remanufacturing services and more. Services now include Caterpillar Accredited Rebuilds (CAR) for longwall roof supports. The CAR program offers a like-new roof support with a new machine warranty and a new serial number, all at a fraction of the cost of a comparable new roof support.

Cat dealers also offers Customer Service Agreements, which deliver an innovative, end-to-end mining solution for the overhaul of underground mining equipment. Cat dealers offer field proven experience in the overhaul of underground mining equipment. The Customer Service Agreement is a guarantee of higher efficiency, delivered through superior quality parts and workmanship, resulting in reliable operation and extended durability.
