Hitachi EX3600-6 hydraulic excavator reaches 100,000-hour milestone at Kumtor – International Mining

Hitachi Construction Machinery says an EX3600-6 ultra-large hydraulic excavator at the Kumtor gold mine, operated by mining company Kumtor Gold in Kyrgyzstan, has achieved a milestone of 100,000 hours of operation.

To commemorate this achievement, Eurasian Machinery LLP, the Hitachi Construction Machinery affiliate responsible for sales and servicing in the Central Asian region, held a ceremony at the gold mine.

Kumtor Gold has a total of five EX3600-6 ultra-large hydraulic excavators, and the excavator that achieved 100,000 hours of operation is a unit that was delivered in 2012.

The Kumtor gold mine is located at an altitude of over 4,000 m in an extremely harsh environment that can reach temperatures as low as –40°C during the winter. Achieving 100,000 hours of operation under such conditions is an important demonstration of the robustness, durability and reliability of Hitachi Construction Machinery products as well as the superiority of parts quality and service systems, HCM says. Over the 11-year period since delivery, Eurasian Machinery has continuously stationed service personnel on site and provided maintenance and services around the clock. As a result, Kumtor Gold has accumulated maintenance know-how and currently conducts its own maintenance while Eurasian Machinery service personnel provide prompt support when needed to ensure stable operation, it added.
