INTRODUCTION

Caterpillar is pleased to offer a comprehensive line up

of underground room and pillar products that include

continuous miners, haulage, roof bolters, and utility

vehicles.

We manufacture these product lines in two locations;

Houston, Pennsylvania and Beresfield, Australia. Both

are Caterpillar facilities that adhere to the Cat Production

System, dedicated to providing our customers with

defect-free products of the highest quality.

We currently sell room and pillar products into appli-

cations that include coal extraction, gypsum, potash

and salt production. In some cases, we purpose build

the machine to work in these applications. For potash

and very hard coal, we offer a tough cut version of our

continuous miner, the CM445. For applications like

potash that shy away from water use for dust control

we offer oil cooled machines that limit water use. We

can offer products that are suitable for both extremely

low and tall seams.

For additional digital content for these products,

including videos, virtual product tours and animations,
