Caterpillar 793 Haul Truck

Haul truck has 6 percent more payload than its predecessor

The new Cat793 haul truck has 6 percent more payload than its Cat 793F predecessor rigid frame off-road truck. The Caterpillar haul truck has a payload of 265 tons.

With a top speed of 37 mph, the Cat 793 travels at 8 mph on 10 percent grades and can navigate a maximum 25 percent grade fully loaded. Enhanced automatic retarding control automatically selects optimum speed based on grade, payload, and brake oil temperature to increase speed up to 25 percent during retarding.

The 2,650-horsepower (gross) Cat C175-16 engine can achieve over 1 million gallons of fuel burn before overhaul, according to the company. Its enhanced oil filtration system increases engine life, eliminates cartridge filter changes, and allows for extended oil change intervals.

Speed controls allow the operator to set the desired machine speed and control it with a rotary dial, allowing the powertrain to automatically select the optimum gear and engine speed. Advanced Power Electronic Control Strategy transmission maintains forward momentum and torque while shifting with optimum gear selection.

Improvements to the Cat Payload system on the 793 deliver more accurate payload measurement and monitoring. Operator speed coaching helps the operator achieve the truck’s maximum potential, and optional AutoHoist lowers fuel burn and simplifies body dump by automating four continuous operator hand and foot inputs into two easy hand inputs to reduce dump cycle times by up to 12 seconds.

The HP Body offers up to 2.75 tons payload improvement over the Mine Specific Design (MSD) body, which is designed for mature mines. Robust structural elements unite with geometric and steel efficiencies to create the durable, high-volume Coal Body.

Fully integrated autonomous haulage system, Cat MineStar Command for hauling, can increase truck productivity by more than 20 percent, according to the company. Other MineStar telematics solutions can be integrated, including MineStar Fleet; MineStar Detect; and MineStar Health equipment insights.
