Caterpillar Inc. has successfully completed a test of the first all-electric large mining truck in Irving, Texas. This battery-electric 793 large mining truck traversed a seven-kilometer (4.3-mile) course, while Caterpillar engineers monitored over 1,100 data channels, gathering 110,000 data points per second, to validate simulation and modeling capabilities.
When fully loaded to its rated capacity, the truck managed to hit a top speed of 37.3 mph. Despite being loaded, it still traveled 1 kilometer (0.62 mile) up a 10% grade at 12 km/h (7.5 mph) and then performed a 1 kilometer (0.62 mile) run on a 10% downhill grade. The energy that would normally be lost to heat was captured and regenerated to the battery. Upon completion of the test, the truck maintained enough battery energy to perform additional complete cycles.

Our global team came together to develop this battery truck at an accelerated pace to help our customers meet their sustainability commitments. This demonstration is a significant milestone, and we are excited for these trucks to get to work at customers’ sites around the world in the near future,” said Denise Johnson, Resource Industries Group President.
