Caterpillar 797F Haul Truck Overview

The 797 is one of the biggest dump trucks on a mine site. As you can see from the image below, there is quiet a climb into the cab. A ladder stairway leads the operator straight into the cockpit, essentially, you are working at heights when beginning your pre-start checklist.

These machines are expensive to build and operate. Coming in at around 7 million each, with tyres costing anywhere from $45,000 per piece, no wonder mining companies look to hire safe drivers who understand these machine need to be taken care of.
