Komatsu D31 Dozer: Key Specifications
Before delving into the performance and advantages of the Komatsu D31, it’s essential to understand its technical specifications. Knowing the engine, dimensions, and other critical factors will give you a clearer picture of what makes this dozer stand out.
- Engine: The Komatsu D31 is equipped with a reliable, diesel-powered engine that delivers impressive horsepower. It features a 4-cylinder, turbocharged engine, typically offering around 75 to 85 horsepower, depending on the specific model variant.
- Weight: The operating weight of the D31 is approximately 16,000 to 18,000 pounds (7,260 to 8,164 kg), which gives it a solid, stable base for various grading and pushing tasks.
- Blade Types: The D31 can be fitted with various blade options, including straight, semi-U, and full-U blades, depending on the required job and terrain. The width typically ranges from 7 to 9 feet (2.13 to 2.74 meters).
- Track: The Komatsu D31 is fitted with durable crawler tracks, providing superior traction on rough and uneven terrain. These tracks help the dozer maintain stability and allow for more precise movements.
- Fuel Capacity: The fuel tank holds approximately 35 to 40 gallons (132 to 151 liters), offering a good range for extended work periods in the field.
- Transmission: The dozer uses a hydrostatic transmission, offering smooth control of speed and direction. This makes it easier for operators to maintain consistent movements during operations.
- Dimensions: With a length of approximately 13 to 14 feet (3.96 to 4.27 meters) and a height of 9 feet (2.74 meters), the Komatsu D31 is compact enough for confined spaces while still offering sufficient power for heavy-duty tasks.
The Komatsu D31 was designed with versatility in mind, excelling in various earthmoving tasks such as land clearing, grading, and roadwork. Here’s a closer look at its performance in different operational conditions:
- Maneuverability: The D31’s hydrostatic transmission provides smooth and easy directional changes. Operators can make sharp turns without the need for manual shifting, which is particularly useful in tight spaces or when handling small grading projects. The overall compact size also allows for easier navigation around obstacles and structures.
- Power and Efficiency: While not the most powerful dozer in Komatsu's lineup, the D31 delivers a solid balance of horsepower and fuel efficiency. Its engine is designed to deliver consistent performance over extended periods, making it ideal for projects where productivity and uptime are essential.
- Hydraulic System: The D31 is equipped with a hydraulic system that provides quick and responsive blade control. This system ensures that the blade can be adjusted smoothly, whether for rough grading or fine-tuning, enhancing the precision of work done.
- Traction and Stability: The crawler tracks give the D31 excellent traction on uneven and soft ground. Its low ground pressure allows it to work in challenging terrains where traditional wheeled equipment might struggle. Additionally, the dozer's weight distribution ensures good stability, even during heavy pushing or lifting tasks.
Several aspects of the Komatsu D31 make it a preferred choice for many operators and contractors:
- Fuel Efficiency: The D31’s engine is designed for fuel efficiency, reducing operating costs over long periods. Its turbocharged engine and hydraulic efficiency minimize fuel consumption while maximizing power output.
