Key Features of the Komatsu D61PX-15
The D61PX-15 combines advanced technology with user-friendly features to enhance its performance, operator comfort, and machine durability.
1. Engine and Performance

• Engine Model: Komatsu SAA6D114E-6
  
• Rated Power: 176 kW (236 hp) at 2,000 rpm
  
• Torque: 1,014 Nm at 1,400 rpm
  
• Fuel Tank Capacity: 400 liters
  

The Komatsu D61PX-15 is powered by a high-efficiency engine that provides excellent fuel efficiency without compromising on performance. Its 176 kW engine enables it to tackle heavy loads while maintaining smooth and consistent operation. The engine is also designed to comply with strict emissions standards, ensuring environmental friendliness.
2. Hydraulics and Blade Control

• Hydraulic System: Load sensing hydraulic system with variable displacement pump
  
• Blade Control: Power angle tilt blade, providing enhanced flexibility for different applications
  

The D61PX-15 is equipped with a state-of-the-art hydraulic system that increases the responsiveness and precision of blade control. The load-sensing system ensures that hydraulic fluid is delivered where it's needed most, optimizing fuel consumption and improving the machine's overall efficiency. The power angle tilt blade can be adjusted to suit different terrains and project requirements, ensuring that operators can work with precision in varying conditions.
3. Undercarriage and Ground Pressure

• Track Type: PZ (Parallel Link Undercarriage)
  
• Ground Pressure: 0.48 kg/cm²
  

One of the standout features of the D61PX-15 is its undercarriage design. The parallel link undercarriage (PZ) offers superior traction and stability, even on softer or uneven ground. This makes the dozer particularly effective for work in tough conditions like loose soil, sand, or mud. The ground pressure is low compared to other dozers in its class, which allows it to operate with minimal ground disturbance, reducing the impact on the surrounding environment.
4. Operator Comfort and Safety

• Cab Design: Spacious, air-conditioned operator cabin
  
• Visibility: Excellent all-around visibility with wide windows and high-mounted mirrors
  
• Control System: Easy-to-use electronic control panel with customizable settings
  

Komatsu places a strong emphasis on operator comfort and safety. The D61PX-15’s cab is spacious, air-conditioned, and features ergonomic controls that reduce operator fatigue during long working hours. The machine is also equipped with advanced safety features, including ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) to protect the operator in case of an accident.
5. Fuel Efficiency and Maintenance

• Fuel Consumption: 15–20% lower than previous models, thanks to advanced engine and hydraulic technologies
  
• Maintenance: Easy access to key components for routine maintenance
  

Fuel efficiency is a key selling point for the D61PX-15. Thanks to innovations in the engine and hydraulic systems, fuel consumption has been significantly reduced compared to older models. This reduction in fuel use translates to lower operating costs over the life of the machine. In addition, the D61PX-15 is designed with ease of maintenance in mind, with accessible components that reduce downtime and make routine servicing quicker and simpler.
