The ʜɪᴛachi EX8000-6 hydraulic excavator, which ʜɪᴛachi Construction Machinery first unveiled in 2012, is currently the second-largest hydraulic excavator in the world. It has a backhoe and a shovel attachment and weighs 811 tons. Aᴜsᴛʀᴀʟɪᴀ’s Stanwell’s Meandu coal mine received the first ʜɪᴛachi EX8000-6 ultra-large backhoe excavator in September 2013.
The hydraulic excavator measures 10.5, 9.9, 8.65, and 10.5 meters in length, breadth, and undercarriage, with a maximum digging depth of 20.5 meters. The excavator can remove 75t of material in a single load thanks to its 45m3 bucket capacity and 40m3 shovel capacity. The shovel has 2,870kN of crowding force and 2,230kN of breakout force.
Two Cummins QSKTA60-CE 16-cylinder diesel engines that provide 3,880 horsepower at 1,800 rpm power the ʜɪᴛachi EX8000-6. Two ʜɪᴛachi TFOA-KK electric motors with a combined capacity of 2,400kW are installed in the ʜɪᴛachi EX8000E-6 electric excavator.
The rigid box construction resists bending and twisting forces. A sturdy cast track structure gives this crucial position additional strength. On challenging job locations, tough bottom rollers, track links, and drive tumblers boost durability. In order to keep the right track tension constant, nitrogen gas accumulators absorb aberrant track tension.
