9 Fuel Saving Tips for Excavators

by Robin Goodman on August 18, 2020


Tip 1: Avoid invalid actions

100% of the oil consumed by ineffective actions is wasted. The construction method should be designed according to the conditions of the construction site. Do not make too many rotations. When loading the truck, try to take soil from the front and try to avoid rotating to the back door to take soil. The height of the excavator should be appropriate, and the soil should not be dug out repeatedly.


Tip 2: Avoid idling the engine

Even if it is idling, there will still be oil in the hydraulic pump that will cycle and consume fuel. Assuming that a 20-ton excavator is idling for 1 hour out of 10 hours of work a day, then about 20 kg of fuel is wasted every day!


Tip 3: Avoid overloading

When the excavated sand or stones are overloaded, the excavator will fall into a depressed state. Assuming that 6 minutes of the work of 1 day and 10 hours are depressurized, then if you can avoid depressurization, you can throttle about 840 liters of diesel every year


Tip 4: Reduce engine speed

The higher the engine speed, the faster the walking speed, and the higher turning part consumes more fuel. Fuel efficiency is better when walking at low speeds than when walking at high speeds.


Tip 5: Reduce the circling angle

Reducing the hover angle when loading the dump truck can shorten the work cycle, increase the amount of work during working hours, and improve fuel efficiency. This is also the most useful way to save fuel.


Tip 6: Clean the dirt on the travel device regularly

The walking device is covered with mud and the resistance increases when walking, which is the cause of the increase in fuel consumption. Therefore, the mud must be cleaned regularly.


Technique 7: Control the mining angle

When the bucket cylinder and the connecting rod, the stick cylinder and the stick are all at 90 degrees, each cylinder has the greatest force to push the excavator. When digging at the beginning, do not extend the stick to the maximum range, starting from about 80% of it is the best.


Tip 8: Control the digging range of the stick

The control stick ranges from 45 degrees from the far side to 30 degrees on the inside. There is a slight difference due to the digging depth, but the boom and bucket should generally be operated within this range, and should not be operated to the end of the stroke of the cylinder.


Tip 9: Arrange the order of excavation reasonably

When digging trenches, first dig trench sides, and then dig the middle part. This saves a lot of trouble and effort when digging the middle.
