The new Caterpillar AD55B articulated truck for underground mining replaces the AD55 and features more power and enhanced braking and retarding for faster speed on grade and greater productivity. The 55-metric-ton-capacity truck also has new components and layouts for improved reliability and operator comfort, and easier maintenance. The truck is equipped with Caterpillar’s C27 ACERT engine with a gross power of 805, 19 percent more compared with the previous model. Similarly, torque is up 30 percent. The result is a 20 percent increase in speed when fully loaded and ascending a 14 percent grade.
