Bell B50D Articulated Dump Truck

According to the company, its 488-horsepower B50D is the largest model sold in North America. Bell trucks feature a sealed switch pad, which is designed to provide fingertip control of 90 percent of the truck’s functions. An on-board weighing system, visible to both driver and loader operator, is standard, and an inclinometer, says Bell, protects against rollovers during dumping. Other features include automatic retarding and traction-control differentials.
