Introduction to the Komatsu PC400
The Komatsu PC400 is a popular model in Komatsu's line of hydraulic excavators. It has been widely used in construction, mining, and heavy industrial applications. The PC400 series is known for its power, reliability, and efficient operation, making it a preferred choice for companies that require heavy-duty excavation work. Komatsu, a Japanese multinational corporation, is a leader in the heavy machinery industry, producing a wide range of equipment that includes bulldozers, wheel loaders, and hydraulic excavators.
The PC400 is designed to handle large-scale tasks with ease, offering a combination of lifting capacity, digging force, and speed. One of the key features of this machine is its robust engine, which provides the necessary power to perform under tough conditions.
Engine Specifications of the Komatsu PC400
The engine of the Komatsu PC400 is a critical component that powers the excavator. As with many large excavators, the engine’s performance directly impacts the machine’s efficiency, reliability, and ability to handle heavy workloads. Below are the main engine specifications for the Komatsu PC400:

• Engine Type: 6-cylinder, turbocharged diesel engine
  
• Engine Power: Approximately 290 to 350 horsepower (depending on the specific configuration)
  
• Engine Model: Komatsu SAA6D140E-5
  
• Displacement: Around 9.8 liters (598 cubic inches)
  
• Fuel Tank Capacity: 450 to 500 liters (118 to 132 gallons)
  
• Cooling System: Radiator, oil cooler, and intercooler for efficient temperature management
  

The engine is designed to operate under demanding conditions, providing the necessary torque and horsepower to lift, dig, and maneuver heavy materials with precision. It is also engineered for fuel efficiency, which is important in the long run for reducing operational costs, especially on large projects that require extensive machine hours.
Weight of the Komatsu PC400 Engine
When discussing the overall weight of the Komatsu PC400, it’s essential to consider both the weight of the engine itself and the weight of the entire excavator, as the engine is a central part of the machine’s overall mass. The weight of the engine plays a significant role in determining the machine’s stability, lifting capacity, and maneuverability.

• Engine Weight: The engine itself weighs approximately 1,800 to 2,000 kilograms (4,000 to 4,400 pounds), depending on the configuration and whether it includes auxiliary components such as the turbocharger and fuel system.
  
• Operating Weight: The total operating weight of the Komatsu PC400 is around 40,000 to 45,000 kilograms (88,000 to 99,000 pounds). This weight includes the chassis, boom, arm, bucket, and counterweight, in addition to the engine.
  

The engine weight is an important factor because it directly impacts the machine's overall balance and performance. A heavier engine provides more power but requires careful design considerations to ensure that the excavator remains stable during operation.
Key Features and Performance
The Komatsu PC400 is equipped with several features that enhance its performance, fuel efficiency, and operator comfort. Some of these features include:

1. Hydraulic System: The PC400 is equipped with a high-performance hydraulic system that provides smooth and efficient operation, allowing for quick and precise movements. This system enables the machine to perform tasks such as digging, lifting, and moving heavy materials with ease.
   
2. Fuel Efficiency: The engine and hydraulic systems are designed to optimize fuel consumption, which helps reduce the overall cost of operation. This makes the PC400 ideal for long-duration projects where fuel consumption can quickly become a significant part of the operating costs.
   
3. Operator Comfort: The cabin of the PC400 is designed with the operator in mind, offering a spacious environment with adjustable seats, air conditioning, and ergonomic controls. The visibility from the cabin is also excellent, ensuring that operators can perform tasks with greater precision and safety.
   
4. Durability and Maintenance: Komatsu’s engineering ensures that the PC400 is built to last. The excavator is designed with durable components that can withstand the wear and tear of tough working conditions. Regular maintenance is made easier with accessible service points and a well-organized design.
