Gillette, WY — Feb. 18, 2003 — LeTourneau, Inc. and Bridgestone/Firestone Off Road Tire Company (BFOR) recently announced the official debut of the L-2350, the world’s largest front-end loader, equipped with the world’s largest loader tires, the Firestone 70/70-57.

The mammoth loader and tires were commissioned at the Triton North Rochelle Mine in Gillette, Wyo., on Nov. 22, 2002. One key feature that the L-2350 offers Triton North Rochelle is greater flexibility in moving from one location in the pit to another. For example, the L-2350 can move to a new location in 20 minutes compared to a traditional track shovel which may take as long as 12 hours for the same move.

The LeTourneau L-2350 is designed for centre-load haul trucks with capacities of up to 400 tons and provides an operating payload of 160,000 lb, a 24-ft dump clearance and an 11.5-ft reach.

The Firestone 70/70-57 Super Rock Grip Deep Tread tire towers almost 13 ft tall and weighs nearly eight tons. A four-person crew assembles each tire in approximately 17 hours with an additional 24 hours in cure time.

The 70/70-57 was designed in cooperation with LeTourneau to specifically meet the requirements of the LeTourneau L-2350.

“We’re excited to see the Firestone 70/70-57 put to work on the LeTourneau loader,” said Manny Cicero, president of BFOR. “This gigantic, history-making machine demanded a tire that could measure up to its stature and capabilities.”
