Comparison of Komatsu D355A Types and Applications

Engine and Performance

The heart of the Komatsu D355A is its powerful engine, which provides remarkable horsepower and torque, ensuring it can handle tough tasks with ease. The D355A series features a turbocharged engine that maximizes power output while minimizing fuel consumption. With a horsepower range from 410 to 450, depending on the model, and torque exceeding 1,350 lb-ft, these bulldozers are designed to perform under heavy loads.

The direct injection and mechanical governor contribute to improved fuel economy, making the D355A an efficient choice for long-term operations. Additionally, the all-speed lubrication and double filters ensure the engine remains clean and well-maintained, reducing downtime caused by maintenance issues.

Comfort and Operator Controls

Operator comfort is a significant consideration in the design of the Komatsu D355A. The machine features a bucket-type reclining oil suspension seat that absorbs shocks and vibrations, making it easier for operators to work long hours without fatigue. The single lever control system simplifies operation, allowing the operator to adjust speed and direction with minimal effort.

An alarm system alerts the operator if the load exceeds the set capacity, enhancing safety and protecting the machine from potential damage. The intuitive controls and dashboard warnings for engine temperature and oil pressure further enhance the operator’s ability to monitor the machine’s status effectively.

Undercarriage and Durability

The undercarriage of the Komatsu D355A is built for longevity and reliability. It incorporates unique dust seals that prevent dirt from entering critical components while retaining essential lubricants. This design reduces wear and tear, resulting in lower maintenance costs over time.

Self-lubricating rollers eliminate the need for frequent maintenance, setting the D355A apart from competitors. The wet-type interconnected steering clutches and brakes provide easier operation while extending the service life compared to traditional dry-type units.

Versatility and Applications

The versatility of the Komatsu D355A makes it suitable for various applications, including:

• Heavy Construction: Ideal for grading, excavating, and moving large volumes of earth.
• Mining Operations: Efficiently handles overburden removal and site preparation.
• Land Reclamation: Used in projects aimed at restoring or rehabilitating land.
• Road Construction: Perfect for shaping and leveling roads, highways, and other infrastructure projects.

The ability to adapt to different tasks is one of the reasons the D355A has remained a popular choice in the industry.
