With a load-sensing system that adjusts hydraulic flow based on the work demand, the excavator reduces fuel consumption without compromising on performance.
5. Fuel Efficiency
One of the standout features of the Komatsu 1250 is its focus on fuel efficiency. The machine is designed to reduce fuel consumption without sacrificing power. This is especially important for long-term operations, where fuel costs can significantly impact the bottom line. The efficient engine and hydraulic system work together to keep operating costs down.
Applications of the Komatsu 1250
The Komatsu 1250 is typically used in large-scale open-pit mining operations, where it is responsible for heavy excavation, material handling, and digging. Some of the primary applications include:

• Excavation of earth and overburden: The 1250 is designed for high productivity when digging large amounts of material from the ground.
  
• Mining material handling: Once the material is extracted, the excavator can be used for loading dump trucks or conveyors.
  
• General material transport: The powerful engine and large bucket capacity allow it to handle a wide range of materials, from rocks and ores to sand and gravel.
  

Common Issues and Solutions
While the Komatsu 1250 is a highly reliable machine, there are a few common issues that operators may encounter. Below are some of the most frequent problems and their possible solutions:
1. Hydraulic System Leaks
Leaks in the hydraulic system can significantly affect the performance of the excavator. These can be caused by worn seals or damaged hydraulic lines.

• Solution: Regularly inspect the hydraulic system for leaks. Replacing damaged seals and hoses can prevent further damage and ensure optimal performance.
  

2. Engine Overheating
The Komatsu 1250’s engine can overheat if the cooling system is not functioning properly. This could be due to a clogged radiator, low coolant levels, or a malfunctioning thermostat.

• Solution: Regularly check the cooling system to ensure it is functioning properly. Clean the radiator, check coolant levels, and replace faulty parts to prevent overheating.
  

3. Wear on Tracks
Over time, the tracks on heavy excavators like the Komatsu 1250 can wear out due to continuous use in harsh conditions. Worn tracks can reduce the efficiency of the excavator and lead to costly repairs.

• Solution: Keep the tracks properly lubricated and inspect them regularly for signs of wear. Replacing the tracks when they become excessively worn can help maintain the performance of the machine.
