Cat 785C 789C & 793C Fuel consumption rates

[JoshLowe]

Hi All,

I was wondering is anyone had any fuel consumption metrics for the above mentioned trucks? I can capture ground speed, selected gear, actual gear, gradient of the ground, RPM's, payload, accelerator position and so on, but does anyone have a metric that i can use to combine all of these to get a fuel usage figure?

Thanks.

Josh.

Is this for estimating?

In the caterpillar performance book, edition 38 for the trucks you are talking about, chapter 20 there is a section for estimating cost.

Truck 789C
Low load:70.6-105.9 liters per hour
Medium load : 105.9-141.2 lph
High load: 141.2-176.5 lph

Truck 793D
Low load:90.8-136.2 liters per hour
Medium load : 136.5-181.6 lph
High load: 181.6-227 lph

Low load: continuous operation at an average gross weight less than recommended. Excellent haul roads. No overloading, low load factor.
Medium load: Continuos operation at an average gross weight approaching recommended. Minimal overloading, good haul roads, moderate load factor.
High Continuous operation at or above maximun recommended gross weight. Overloading, poor haul roads, high load factor.
