Tram Chain
Tram chains are a unique roller chain style designed similarly to standard transmission roller chains but more specifically to feeder applications in continuous mining machinery. Mining tram chains are often used in a parallel two-strand configuration with flight bars (slats) placed between and connecting the chains. This configuration allows mined materials to be conveyed highly effectively with the slats. Our genuine tier-one tram chains directly interchange with other brands and utilize specific features and material grades to maximize strength, durability, and performance. For additional information or to get a quote on the tram chain, contact our customer service team; we will be happy to assist you!
