In order to reduce the operating cost of the excavator, in addition to reducing the maintenance cost, it is how to reduce the fuel consumption. Since refueling is unavoidable, we must work hard to save fuel.

Tip 1: Try to avoid ineffective actions

The oil consumed by ineffective actions is 100% wasted. The construction method should be designed according to the situation of the construction site, and no unnecessary rotation should be done. When loading the truck, try to collect soil from the front, and try to avoid rotating to the back door to collect soil. The height of the excavator should be suitable, and the soil should not be dug up and down repeatedly.

Tip 2: Avoid engine idling

Even when idling, there is still oil circulating in the hydraulic pump and consuming fuel. Assuming that a 20-ton excavator is idling for 1 hour in a 10-hour work day, about 20 liters of fuel is wasted every day!

Tip 3: Avoid overloading and dropping pressure

When the excavated sand or stones are overloaded, the excavator will fall into the state of falling pressure. Assuming that 6 minutes of a 10-hour work day is in the form of pressure drop, then if you can avoid pressure drop, you can save about 840 liters of diesel per year. Therefore, in the process of operation, if a shovel cannot handle the problem, don’t be impatient, you can deal with it in two parts, otherwise it will not only waste equipment, but also consume oil, and the small will lose the big.

Tip 4: Reduce the engine speed

Putting the engine throttle in the economical gear position, although reducing the engine speed will affect the workload, but it can greatly reduce fuel consumption and improve fuel consumption efficiency.

Tip 5: Reduce the hovering angle

Reducing the hover angle when loading a dump truck can shorten the cycle time, increase the amount of work per unit work time, and improve fuel efficiency. This is also the most effective way to save fuel.

Tip 6: Reduce the engine speed when walking

The faster the engine revs, the more fuel is consumed while walking.

Tip 7: Perform high-level mining

The excavator work platform is most effective when it is the same height or slightly higher than the truck.

Tip 8: Reasonably control the digging angle

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

Skill 9: Reasonably control the excavation range of the stick

Control the stick within an angular range of 45 degrees from the far side to 30 degrees from the inside. There will be slight differences depending on the digging depth, but generally the boom and bucket should be operated within this range and should not be operated to the end of the cylinder stroke.

Tip 10: Arrange the excavation sequence reasonably

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

Tip 11: The smaller the digging depth, the better the economy when digging

The amount is mined in segments. The excavation is divided into upper, middle and lower layers. If you dig from the bottom to the top at one time, first of all, the scope of action will be increased, and secondly, the power of the excavator will be reduced due to the increase of the scope, which will reduce the work efficiency, which will cost a lot of oil.

Tip 12: Prevent diesel from being stolen

Not only does it take a lot of effort to use it, in fact, being stolen once is equivalent to a few days' wages! There are only three ways for thieves to get diesel oil out of the fuel tank. First, from the subsea valve; second, from the oil outlet; third, from the fuel filler. Next, I will analyze and analyze how to prevent theft in three ways.

These tips for fuel-saving operation may not even be noticed by old operators, but as long as they can develop good operating habits, they can indeed save considerable fuel costs over time.
