📍 Rolleston Open Cut. The mining process is undertaken with two large electric walking draglines, three electric rope shovels, three hydraulic excavators and rear dump trucks, with tracked dozers and other ancillary equipment to support these machines. Did you know the average suspended load of the dragline bucket at this operation is approximately 290 tonnes? That’s the equivalent of almost 3 adult blue whales 🐳 or 48 African bull elephants 🐘 | Glencore

What the heck is a dragline, and how do they work? We’re back with North American Coal to tour one of their massive draglines. These machines are the largest earthmovers in America, capable of moving well over 100,000 cubic yards of material per day. | Aaron Witt
