Tram Chain

Tram chains are based on standard transmission chain construction but used in feeder applications on continuous mining machinery. The chains are operated in twin strand format with flight bars making the two strands common. Typical pitches are 2.00 “(50.8 mm) and 2.50” (63.50 mm). Materials are enhanced to ensure higher strengths and wear resistance.
