caterpillar_797b
The Caterpillar 797B is an off-highway, ultra class, two-axle, mechanical powertrain haul truck developed and manufactured by Caterpillar Inc. in the United States specifically for high production mining and heavy-duty construction applications world-wide.
Update V1.2 Thanks to luftfisch findings and recommendations, I changed the traction effort to 24 for increased power on steeper grades. But they still slow to about half speed on the steep grades when full, empty they can reach top speed. Also the top speed was changed to 27 mph. I personally thought 42 was too fast myself.
