How to save fuel on excavators! Remember these 8 points and you can save tens of thousands a year

[DIG-DOG]

What should I do if the fuel consumption of the excavator is high? What should I do if the oil price rises and I can't make money? How to save fuel for excavators has become one of the most concerned topics for users. Under the condition of consuming the least fuel, you can still make more money. This is naturally the result that every operator hopes for. It is naturally more difficult to achieve the goal of saving fuel without affecting the life of the excavator.

In order to achieve the goal of saving fuel, the operator has many points to pay attention to when operating the excavator. The following is a compilation of eight fuel-saving treasures shared by veteran drivers, and analyzes how to save fuel from an operational perspective.

1. Master the correct operation of the excavator

In order to reduce unnecessary operations that increase fuel consumption when operating the excavator, the premise is that you must first know the basic operations of the excavator well, and master the correct operations of loading, walking, rotating, leveling, and slope repairing. Who can blame the excavator for fuel consumption if the foundation is not good? I would like to remind novices who have just entered the industry to listen to the advice of the master and learn the excavation operation well.

2. Reduce unnecessary idling

If you want to save fuel, you must reduce the necessary idling speed of the engine. It should be clear that when the excavator is idling, it is also using the hydraulic pump to circulate the hydraulic oil. The longer the idling time, the more fuel is wasted. The correct way to save fuel is to try not to drive the excavator at idle speed when on standby or rest. This is one of the secrets to saving fuel.

3. Reduce the engine speed

When performing the same excavation operation, when the engine is at the highest speed, the operating speed is fast, but the fuel consumption is high; when operating at non-full throttle, appropriately reduce the engine speed (without affecting the operating efficiency). Although the operating speed is reduced, it can reduce fuel consumption and improve fuel efficiency.

4. Walking at non-full throttle

It is best to walk at non-full throttle of the engine. Everyone should know that the higher the engine speed, the faster the walking speed and the higher the fuel consumption. Reducing the engine speed during operation can improve the fuel consumption efficiency during walking.

5. Reduce the rotation angle

Try to reduce the rotation angle. When loading a dump truck, if the rotation angle is small, the operation cycle can be shortened, the amount of work per unit time can be increased, and the fuel efficiency can be improved. Finally, the truck can be placed closer to the excavator.

6. Excavation with high-position excavator

As shown in the figure, first excavate the higher part, and then excavate the lower part. Compared with low-position excavation, high-position excavation can shorten the cycle time by about 12%, which is more fuel-efficient.

7. Try not to do invalid actions

If you want to save fuel, you should also pay attention to minimizing invalid actions. Invalid actions can only waste more oil in vain. Operate according to the specific conditions of the construction work, avoid unnecessary rotation, and choose the appropriate excavation height. Do not repeat the excavation action, etc.

8. The operating range of the bucket arm

When the bucket cylinder and connecting rod, the bucket arm cylinder and the bucket arm are all 90 degrees, each cylinder pushes the excavator with the greatest force. When excavating at the beginning, do not extend the bucket arm to the maximum range of action. Starting from about 80% is the best effect.

Summary: The above is just a brief introduction to 8 fuel-saving operations. Of course, there are many things to pay attention to if you want to save fuel. The next article will introduce you to maintenance methods to save fuel.
