In a gold mine has Hitachi EH 4000 Haul trucks. Truck has 16mm AR400 HBN abrasion resistance plate in the floor.

With this solution the life time of the truck liners was expected to be increased from 5.000 hours to 17.000 hours. Now it is at 12.000 hours and there is very little wear on the Hardox® 600. So, it is expected to see life time more than 17.000 hours.
