On construction projects that run under the hot sun or with long working hours, excavator performance is often tested to the maximum. One of the most frequently complained about problems is that the excavator's power feels weak when the temperature is hot. Symptoms can include slow movements, digging power decreases, until the engine feels heavy even though the RPM increases.
This condition does not only interfere with productivity, but it also has the potential to cause serious damage if left unchecked. Understanding the causes of weak excavator power when hot and knowing how to overcome them are important steps so that the equipment continues to work optimally and the project goes according to plan.
Drowning Excavator Energy Characteristics
Excavator power that begins to decline is usually marked by several symptoms that are quite easy to recognize in the field. The operator will feel that boom response, arm, or the bucket becomes slower than normal conditions. The machine seems to work harder, but the results of the work are not commensurate with the energy expended.
In some cases, The excavator's performance looks normal at the start of operation, but it starts to decrease after the tool has been working for a long time or when the environmental temperature gets hotter. This is an early indication that the engine or hydraulic system is starting to experience a decline in performance.
Why Excavator Power Can Lose When Temperatures Are Hot?
After knowing the characteristics above, There are several reasons why an excavator's power can become weak when the engine temperature is hot, that is:
1. Machine Overheating
One of the main causes of weak excavator power is overheating of the engine. When the engine temperature exceeds the ideal limit, The system will reduce performance automatically to protect internal components. On modern excavators, The ECU plays a role in limiting power so that the engine does not suffer further damage.
as a result, even though the engine is still running, The power produced is not optimal and feels weak when used for heavy work.
2. Hydraulic Oil Too Hot
Apart from machines, The hydraulic system is also very sensitive to temperature. Hydraulic oil that is too hot will experience a decrease in viscosity, so the hydraulic pressure is unstable. This condition makes tool movements slow and less responsive.
In the long run, Hydraulic oil that continues to work at high temperatures can accelerate wear of hydraulic components.
3. Cooling System Not Working Optimally
A problematic cooling system is often the main trigger for an increase in engine temperature. Dirty radiator due to project dust, cooling fan that is not optimal, or coolant that is lacking and has decreased in quality can prevent heat from being dissipated properly.
Without optimal cooling, engine and hydraulic temperatures will continue to increase and have a direct impact on excavator power.
4. Too Heavy Workload
Forcing the excavator to work beyond its capacity, especially in hot conditions, is also a factor causing decreased energy. Working hours that are too long without cooling breaks make the engine and hydraulic system work continuously until their performance decreases.
5. Dirty Engine Filters and Support Components
Dirty air filters and fuel filters inhibit the supply of air and fuel to the engine. as a result, the combustion process does not run optimally and the power produced is reduced, especially when the engine works in high temperatures.
What are the impacts if the excavator's power is left weak??
If this condition is not treated immediately, the impact could be even wider. Project productivity decreases as work hours become longer. Fuel consumption actually increases because the engine works harder to produce the same power.
Besides that, the risk of damage to the engine and hydraulic system is also greater, which ultimately leads to downtime and quite a lot of repair costs.
Solution to Overcome Excavator Power Weakness when Hot
For those of you who are confused about dealing with excavator power that suddenly becomes weak when the temperature is hot, we have the solution below:
1. Stop Operation and Lower Engine Temperature
The first step that needs to be taken is to temporarily stop the operation of the tool. Let the engine run at idle according to the SOP to help reduce the temperature gradually. Avoid turning off the engine suddenly when the temperature is very high.
2. Check and Clean the Cooling System
Make sure the radiator is clean from project dust and dirt. Check the cooling fan and ensure that air flow is not restricted. Besides that, Check the coolant level and quality regularly so that the cooling system works optimally.
3. Check Engine Oil and Hydraulic Oil
Use engine oil and hydraulic oil according to the manufacturer's specifications. If the quality of the oil has decreased or often overheats, make a replacement immediately. Good oil helps maintain temperature stability and tool performance.
4. Set Tool Working Pattern
Setting working hours wiser is very helpful maintain excavator performance. Avoid continuous operation without pause, especially during the day with extreme temperatures. Gradually dividing the workload can prevent the equipment from working too hard.
5. Perform P2H Consistently
Daily Check of Tools (P2H) is an important step to detect potential problems early. By regularly checking the temperature indicator, oil condition, and cooling system, The risk of the excavator running down can be minimized.
How to prevent excavator power from remaining optimal?
Prevention is always better than repair. Routine maintenance, operator training, as well as selecting an excavator that suits project needs will help keep the tool's performance stable even when working in hot conditions.
Regular monitoring of engine and hydraulic temperatures also helps make quick decisions before problems develop further.
