The cost of operation is considered a secondary factor when buying or renting heavy equipment, this will be directly linked to the amount of fuel consumed by the vehicle in a given period of time. Through a simple operation, it can be established that:

The total cost in fuel per hour = [Fuel consumption per hour ] x [Fuel price]

The previous operation gives us the specific picture in relation to the cost of the total fuel consumed by the vehicle, however sometimes the variable “Fuel consumption per hour” is unknown and this could vary depending on the load factor received by the engine and of the type of operation that the machine performs.

In the case of excavation vehicles, as well as other machines, the engine load factor can be directly influenced by any of the following variables affecting the final fuel consumption:

  • Parking periods in idle (keep the vehicle on without movement)
  • Manipulation of the tool implemented in the excavator or vehicle
  • Movement of the excavator without load
  • Maniobras with partial acceleration
  • Work downhill

Other variables of great importance when determining the fuel consumption per hour are classified according to the application of the excavator that can be summarized in any of the following 3 cases:

Low Consumption

Low power consumption tasks are those that lead the engine to a load factor of between 20 to 40%, such as Excavation and movement of material to the designated station located at ground level, digging of shallow ditches for public works or application on low-density materials, including the movement of scrap metal.

Average Consumption

The work of average consumption leads the engine to a load factor with 40 to 60%, among them stands out: The interrupted load of trucks, excavation of materials with low to medium density and with the service ladle between 60 to 90% of their capacity. It includes the loading of logs, modification of landscapes, etc. In which the team makes few trips with distances ranging between 100 and 200 meters

High Consumption

The work of high consumption will lead the engine to a load factor of 60 to 80%, the most common tasks include the continuous loading of trucks, excavation in rock or blast rock floors, transport displacements exceeding 200m in length in those that the soil provides difficult traction and great impacts.

Below is a table of fuel consumption per hour in the excavators most commonly used in the construction industry:

Excavator Low consumption per hour in liters Average consumption per hour in liters High consumption per hour in liters Type of engine technology Tank capacity
321D LCR 6 to 12 12 a 18 18 to 24 TIER 3 (STD) 410 Liters
321D LCR 6.5 to 12.5 12.5 to 18.5 18.5 to 24.5 TIER 3 (HPP) 410 Liters
320D 6 to 12 12 a 18 18 to 24 TIER 3 (STD) 410 Liters
320D 6.5 to 12.5 12.5 to 18.5 18.5 to 24.5 TIER 3 (HPP) 410 Liters
320C 10 a 14 17 to 20 20 to 23 Conventional
330D L 20 to 25.5 liters 35 to 39 liters 45 to 49 liters TIER 3 620 Liters

The consumptions established in the table consider:

  • The difference of 12% that could exist between two operators
  • 80% load factor with intermittent periods to 100%

To carry out an approximate calculation of the fuel consumption per hour in liters for other vehicles, the following operation can be carried out:

Fuel consumption per hour = [Engine power in hp (horsepower)] / [number of cylinders in the vehicle.]

Remember that the result may vary depending on the technology of the engine and the variants mentioned in the publication

At Transportation we provide a catalog of products that include excavators with low fuel consumption, if you want more information please contact us.
