Caterpillar is moving forward with its large mining trucks, representing its largest investment ever in mining technology. The Cat 793F and 797F mechanical drive trucks and the 795F AC electric drive truck are all achieving milestones.
The 793F and the 797F have accumulated more than 75,000 hours of field testing and have proven their performance capabilities and their durability. The new Cat C175 engine that powers them has racked up 130,000 hours of field testing in mining trucks and more than 120,000 hours in power systems. Caterpillar engineers have been testing two 795F AC prototypes. The development programme has provided input for the construction of a new 795F AC.
