Fifty Hitachi EH5000ACII dump trucks are bound for Indonesia, following a large order by mining company Kaltim Prima Coal (KPC). There is already a fleet of 80 Hitachi EH4500 trucks working in KPC mines, as well as 12 EX3600-6 and six EX2500-6 excavators. The new Hitachi fleet is needed to meet the demands of a significant growth in production capacity.
KPC is owned by Bumi Resources, which has its headquarters in Jakarta and mines on the island of Kalimantan – in Sangatta and Bengalon – and two further sites in the south of the island. The company’s mining concession areas (Sangatta and Bengalon) have a current total production capacity of 40.3million tonnes and this is expected to grow to 80million in the next three years. Kalimantan is known for its rich natural resources, including gold and coal, as well as lush areas of rainforest. The mine itself covers 1,961km² and is situated near the coast, where it is well placed to serve its markets.
Production began in 1990 and has steadily increased. In 2008, the coal resources were estimated at 1,548 million tonnes. It is now known to be 7,179million tonnes – an increase of 62 per cent. The fuel produced at the site, Prima coal, is of high-quality, high-energy and medium sulphur, with low ash and moisture. The excavators are used to remove the overburden and dig out the coal, while the trucks transport the overburden around the mine.
Richard Schloss, General Manager of Mining Equipment Maintenance for KPC is particularly satisfied with the after-sales support they receive from Indonesian Hitachi dealer Hexindo. He says: “Hexindo employs 300 people on site to offer support and we also have full maintenance contracts for our machines. Hitachi mining machines are highly reliable and are a huge asset to our daily production at the mine.”
Robert Bruce, Business Development Manager for Hitachi Construction Machinery Australia, says: “We have supplied Hitachi machinery for the mine since it was established in 1990. Initially, it was owned by Rio Tinto and BHP – Bumi Resources purchased KPC in 2003.
“The new owners have been very pleased with the performance
of the excavators and dump trucks, as is clear from this large new order! The last original excavator, an EX3500, was only replaced recently after working for 118,000 hours.”
