Down underground it is a different world, harsh and difficult. Designed for coal transportation underground, the chain conveyors we developed and improved over the years, are strong and reliable, they carry every day the coal mined in all C.N.H. hard coal mines. GEROM manufactures all parts including the gear boxes, head and tail frames, line pans, flight bars, connectors and sprockets. The conveyors can be assembled from component parts quickly due to it’s modular construction.
