The new Caterpillar 785D Mining Truck incorporates new features to boost performance and reliability, reduce engine emissions and enhance safety. The improvements also focus on component commonality to keep parts stocking and maintenance simple. The 785D target payload ranges from 142 to 155 tons (129 to 141 metric tons) depending on the specific configuration.
Using the latest technology, the Cat 3512C HD engine maintains fuel efficiency, delivers 1,348 net horsepower (1005 kW) and is compliant with US EPA Tier II emissions standards. Caterpillar also introduces the X body with the 785D. The X body provides mine specific options (e.g. liners, rail caps, sideboards, etc) for new sites and contractors. The new body also provides greater volume111 cubic yards (85 cubic meters) versus 102 cubic yards (78 cubic meters) for the dual slope body. The canopy of each of the bodies extends farther over the cab for greater protection. A new pump drive system provides continuous rear axle filtration. Benefits include cleaner oil, less downtime and improved component life. Extended life disc brakes may achieve up to double the wear life of standard brakes and are resistant to glazing. The result is consistent braking power and reduced maintenance. New air intake and filters have a new seal, which provides easier servicing and lower maintenance costs.
The 785D retains the Caterpillar mechanical power train that has enabled 785 models to achieve high productivity and reliability in challenging mining conditions around the world.
