On a side note...I go to Vegas every 4 years for a Mining Show called MinExpo. Everyone brings the biggest and the baddest pieces of gear there. I was chatting with a Hitachi rep once and we were talking about some of the larger shovel Hitachi makes. Jaw dropped when he told me the biggest Hitachi shovel needs 15-17,000L of Hydraulic fluid!
Yeah they are an impressive piece of equipment, 43 cubic meter bucket!
