Caterpillar 789
The Caterpillar 789 dump truck is a model of haul trucks, typically used in open pit mining, manufactured by Caterpillar Inc.[1][2] The 789 has a capacity of 177 tonnes, and its engine can produce 1770 horsepower. While some competing products use hybrid drive, the Caterpillar 789 has an entirely mechanical drive-train. The first Caterpillar 789 trucks were introduced in 1986.[3]
The vehicle's controls are designed to work much like those of an ordinary truck.[1] However, they have multiple mechanisms for the driver to slow or stop the vehicle. Next to the traditional brake pedal there is a second foot pedal to activate a secondary braking system. There is a lever to the right of the steering wheel, called the "retarding brake", used for less intense braking. Finally, the vehicle's drive-train will automatically change gears, while descending inclines, to help the driver keep its speed under control.
Because the vehicle provides the driver with a limited view, with many blind spots, they are equipped with multiple proximity sensors, and closed circuit TVs cameras.[1]
