This 2018 Peterbilt 389, operated by James Erickson, is a "pure heavy-haul truck," he said, double-framed with twin steering boxes, 20,000-pound steer axle, 20,000-pound pusher axle and 46,000-pound rear axles. The rig, powered by a tuned 605-hp Cummins X15 with an 18-speed, sits on a 310-inch wheelbase with a 5-foot spread on the pusher and drive axles.
The trailer, which belongs to Walters Transport out of Pipestone, Minnesota, is a custom-built, 80-ton Trail King with a 3-4-2 axle setup and a low transition for backing under different machinery. All stretched out, the length of tractor and trailer is 131.6 feet, Erickson said.
