Cat workers commemorate a milestone on the grader line in Decatur, Illinois.

In 1995, Caterpillar introduced the Cat 24 Motor Grader specifically designed to build and maintain haul roads at mining sites with ultra-class haul trucks. Now in its third generation, the Cat 24 offers 399- to 518-kW (535- to 694-hp) power, 61 950 kg (136,575 lb) weight, a 7.3-m (24-ft) moldboard with an 8.5-m (28-ft) moldboard option, and technology as standard to work wide haul roads efficiently.  

At a ceremony in September, Cat executives and motor grader production team members gathered in Decatur, Illinois to celebrate the production and sale of the 1,000th Cat 24 Motor Grader. The machine, destined for Australia, was sold by Cat dealer, WesTrac Pty Ltd, to Rio Tinto.

Commenting on the historic 1,000th Cat 24 milestone, Sam Vedhakumar Manoharan, vice president of product management, earthmoving, said: “The Cat 24 Motor Grader was and continues to be a game-changer for maintenance efficiency of the wide haul roads necessary for ultra-class trucks. We thank the many global mining operations and dedicated Cat dealers around the world for their loyalty to the Cat 24 grader.”

Today’s Cat 24 Motor Grader features more than 30% higher power, 13% more weight and a longer rebuild life than previous generations.
