Caterpillar introduced a new mining truck in the 793, which features a payload up to 265 tons.

According to Cat, the 793 offers up to 6 percent more payload than the 793F and boasts the highest payload in its size class. Cat says a special body design reduces empty machine weight to increase payload capacity.

The new truck features a top speed of 37 mph, traveling at 8 mph on 10 percent grades. It can navigate a maximum 25 percent grade fully loaded, Cat says. Enhanced automatic retarding control automatically selects the optimum speed based on grade, payload and brake oil temperature to increase speed up to 25 percent during retarding, the company adds.

With a Cat C175-16 engine, the company says the 793 can reach 1 million gallons of fuel burn before overhaul. An enhanced oil filtration system increases engine life, eliminates cartridge filter changes and allows for extended oil change intervals. And with a 2,650-hp rating, Cat says the engine is available in Tier 2 or Tier 4 Final configurations.
