The Caterpillar 793 model runs a distance of 7 km, performing a number of tasks even when the truck is full of dirt, with only the power from the battery pack.
American truck company Caterpillar demonstrated the capabilities of its mining vehicle powered by batteries instead of traditional diesel engines during a test run at the Tucson experimental site, Arizona. The vehicle was developed in collaboration with mining companies including Caterpillar and is still in prototype form.
The total test distance is 7 km, and the Caterpillar 793 truck is capable of reaching a maximum speed of 60 km/h with a full load. Another test was also with a full tank, and the 793 climbed a 10% slope at a speed of 12 km/h.
Then the giant truck turns around to go downhill, using regenerative braking to return energy to the battery. After that, the 793 still has enough battery to perform other cycles, according to Caterpillar. However, the company did not detail the distance the truck could run with a full load in the mine.
Battery-powered electric trucks promise to bring practical benefits to mining areas. This giant green car line will reduce oil use and significantly reduce emissions.
Normally, giant trucks guzzle oil like they drink water. For example, a Belaz 75710 with two 16-cylinder diesel engines with a capacity of 65 liters and each diesel engine with a capacity of 2,300 horsepower will consume about 1,300 liters of oil/100 km. Or a Caterpillar is the 797F with up to 4,000 horsepower from a V20 engine with a capacity of nearly 106,500 cc, consuming about 784 liters/100 km.
