SALT LAKE COUNTY — A timelapse video released by Rio Tinto shows the construction of the massive haul trucks used in Kennecott copper mine.
The trucks are assembled on-site at the Bingham Canyon mine and take about two weeks to put together. Each has a 320-ton capacity and weighs about 1.1 million pounds when fully loaded.
The average size of the truck is 24 feet wide by 29 feet high by 51 feet long, or roughly the size of the average two-story house. Each of the trucks' six tires are more than 12.5 feet tall.
"It takes about 9 truck loads to bring all the parts here," Rio Tinto spokesperson Kyle Bennett told KSL in November. "We have a build team of seven individuals and they work 8:00 to 5:00 every day for about 15 days to put one of these trucks together."
The haul trucks, adopted late last year, were chosen in part because they are better for the environment, according to Rio Tinto. The trucks are hybrid.
"This haul truck uses a combustion engine to drive an electric generator which then powers electric motors for propulsion," Kennecott worker Eric Eatherton said.
