The Tata Hitachi ZAXIS 870-5G is an 82-ton large-class hydraulic excavator for massive open-pit digging, overburden removal, and high-volume bulk loading at major mining sites in India. It features a turbocharged Isuzu diesel engine delivering approximately 483 HP at 1,800 rpm, providing consistent peak output during heavy mining cycles. Its operating weight is around 80,800 to 82,300 kg, offering the mass needed for large bucket loading on deep bench and pit floors. The maximum digging depth of 8,870 mm across, covering all depth ranges for Indian open-pit operations. Bucket options of 2. 9 to 4. 5 m³ provide very high material throughput per cycle, ideal for bulk excavation and haul truck loading. The HIOS IIIB hydraulic system ensures smooth combined operations, while ECO mode reduces fuel consumption while maintaining full digging power. A heavy-duty undercarriage and reinforced structural components support continuous performance in the toughest mining conditions. Large fuel and hydraulic tank capacities minimize unproductive refueling and service stops at remote mine sites. A production-scale machine for large mining companies and overburden removal contractors operating at high daily tonnage targets in India.
