Western Star Trucks announced that it is collaborating with Somerset, Pa.-based J&J Truck Bodies & Trailers to build the ultimate truck for extreme-duty mining and quarry applications.

The program provides customers with a new Western Star 6900 XD paired with a heavy-duty dump body from J&J. Currently on display in the Western Star booth at CONEXPO-CON/AGG 2008 (#S9412), this truck is built to haul loads up to 40 U.S. tons.

The 6900 XD 40-ton dump is designed to minimize cost per ton of material hauled and maximize shift productivity through efficient fuel consumption, fast cycle times and superior operator comfort.

Key specifications include 110,000-pound planetary drive axles, a Detroit Diesel Series 60 engine with Tier 3 off-highway emission ratings, a fully automatic Allison 4500 RDS transmission, and purpose built dump box. With this configuration, the truck is a cost effective, turn-key solution for mining and quarry customers.

"Western Star is known for its rugged construction and durability, and this is the first time we've offered a body program that caters specifically to the extreme-duty operator," said Chuck Whitehead, vocational segment manager for Western Star Trucks.

The 6900 XD can be up to 35 percent more fuel efficient than traditional off-road haulers when haul distances exceed one mile. The superior fuel economy, combined with stable loaded top speeds of more than 40 miles per hour in the proper application, makes this truck unmatched in cycle time efficiency.
