Finish construction of a Caterpillar 797F, one of 19 being made in Mackay for Bowen Basin coal mines.
The Bowen Basin contains the largest coal reserve in Australia. This major coal producing region contains one of the world's largest deposits of bituminous coal. The Basin contains much of the known Permian coal resources in Queensland including virtually all of the known mineable prime coking coal.
The Bowen Basin covers an area of over 60,000 square kilometres in Central Queensland running from Collinsville to Theodore. The Basin has 34 operational coal mines that can extract over 100 million tonnes annually. There was a combined population of 41,973 people in the area in 2001.
Rio Tinto Coal Australia's Kestrel Mine, near Emerald was named after a bird found in the area. The Ornamental Snake is a small reptile native to the Bowen Basin

The Caterpillar 797F is an off-highway, ultra class, two-axle, mechanical powertrain haul truck developed and manufactured by Caterpillar Inc. in the United States specifically for high production mining and heavy-duty construction applications worldwide. The 797F is the third, current generation model of the 797 series and is Caterpillar's largest, highest payload capacity haul truck.
Compared to the 797B, the 797F has a larger payload capacity and a more powerful, more efficient engine. These changes allowed Caterpillar to meet mine operators' needs to increase operational efficiency and reduce costs by increasing the amount of material hauled per trip. Source:
Caterpillar 797F: Final Assembly
Final assembly of the 797 is completed by Caterpillar field mechanics at or near the customer site. Before the dump body can be joined to the frame, the dump body components must be assembled and welded together by a dedicated team, requiring seven to ten days per dump body. Final assembly of one 797 requires a team of seven mechanics working in three shifts around the clock, seven days per week for 20 days in addition to the time required to assemble and weld the dump body.
