INDIAN MINING & CONSTRUCTION EQUIPMENT INDUSTRY

Image
BACKGROUND & HISTORICAL TRENDS Construction and mining equipment cover a variety of machinery such as hydraulic excavators, wheel loaders, backhoe loaders, bull dozers, dump trucks, tippers, graders, pavers, asphalt drum / wet mix plants, breakers, vibratory compactors, cranes, fork lifts, dozers, off-highway dumpers (20T to 170T), drills, scrapers, motor graders, rope shovels etc. They perform a variety of functions like preparation of ground, excavation, haulage of material, dumping/laying in specified manner, material handling, road construction etc. These equipments are required for both construction and mining activity. With a wide production capacity base, India is perhaps the only developing country, which is totally self-reliant in such highly sophisticated equipment. India has only a few, mainly medium and large companies in the organized sector who manufacture these. The technology barriers are high, especially with respect to mining equipment and therefore the role of SM...
