FMC - Full Maintenance Contract
A key factor for this high availability is support from PT. Hexindo Adiperkasa, the Hitachi dealer in Indonesia and from Hitachi Japan. The site is remote and access from the outside is difficult. To keep all machines in good condition, KPC chose a full maintenance contract (FMC) with Hexindo and Hitachi. Since the first EX3500 was delivered, Hexindo and Hitachi have been maintaining service facilities on the site. Now there are 180 staff members working for 24 hours, seven days a week. The contract was originally agreed upon for a five year period. Then it was extended repeatedly up to the present since KPC has been very happy with the high reliability and availability of their excavators, which is the key factor for successful and profitable operation of this site. The current contract is now up to 96,000 hours.
