IRVING, TX—Caterpillar Inc. has unveiled an electric version of its 793 truck. The big, heavy-payload vehicle, which is used for mining applications in remote locations around the world, recently underwent a series of successful tests at Cat’s proving ground in Green Valley, AZ.
Fully loaded to its rated capacity, the battery-powered truck achieved a top speed of 37.3 mph. It traveled 1 kilometer up a 10 percent grade at 7.5 mph. The truck also performed a 1 kilometer downhill run, capturing the energy that would normally be lost to heat and regenerating that energy to the battery. Upon completing the entire run, the truck maintained enough battery energy to perform additional complete cycles.
