Common Fuel Tank Capacities for Mini Excavators
Mini excavators, as flexible small construction machinery, typically have fuel tank capacities between 20-50 liters. Specific figures depend on the machine size:
1-ton mini excavator: Approximately 20-25 liters.
3-ton small excavator: Approximately 30-40 liters.
5-ton medium excavator: Approximately 45-50 liters.
Key Factors Affecting Fuel Consumption
Fuel tank capacity determines the working time per refueling, but actual range is also affected by these factors:
Engine power: A 15kW model consumes approximately 3-4 liters of fuel per hour.
Work intensity: Breaking operations consume 20% more fuel than regular excavation.
Ambient temperature: Fuel consumption may increase by 10-15% in winter.
Practical Tips for Extending Range
Want your mini excavator to last longer? Try these methods:
Regularly change the air filter to keep the engine breathing smoothly.
Avoid prolonged idling; turn off the engine if it's stopped for more than 5 minutes.
Adjust the throttle according to soil conditions; reduce the engine speed appropriately in loose soil.
