The Komatsu D39EXi-24 is a compact and versatile small dozer designed to deliver exceptional performance in a variety of earthmoving applications.
Here are some key features of this model:
- Intelligent Machine Control Technology: The D39EXi-24 is equipped with Komatsu’s intelligent machine control technology, providing automated blade control for enhanced precision and efficiency during grading operations.
- Efficient Power and Performance: Powered by a robust engine, this small dozer ensures efficient power delivery, enabling it to handle various tasks with agility and effectiveness.
- Compact Design: The compact design of the D39EXi-24 makes it well-suited for operations in confined spaces and urban environments, allowing for increased maneuverability and versatility on job sites.
- Durable Undercarriage: The dozer features a durable undercarriage that contributes to stability and durability, ensuring reliable performance in challenging terrains.
- Operator Comfort: Designed with operator comfort in mind, the cab of the D39EXi-24 provides a ergonomic and spacious environment, reducing operator fatigue during long hours of operation.
- Easy Maintenance: Komatsu emphasizes ease of maintenance, with accessible service points and components, facilitating quick and efficient routine maintenance to maximize uptime.
- Versatile Applications: The small dozer is versatile and well-suited for a range of applications, including grading, dozing, backfilling, and site preparation, making it a valuable asset on construction and landscaping projects.
- Advanced Controls: The dozer is equipped with advanced controls that enhance the operator’s ability to maneuver the machine precisely, contributing to efficient and accurate earthmoving operations.
The Komatsu D39EXi-24 small dozer combines advanced technology with a compact and durable design, making it an excellent choice for contractors and operators seeking high performance in a smaller package.
Proactive Dozing Control: The dozer features proactive dozing control, enabling even less experienced operators to automatically cut or strip from existing terrain. By measuring the terrain it tracks over, the dozer plans the next pass, potentially improving productivity by up to 60% compared to the previous generation.
Automatic Fill Material Spreading: With lift layer control, operators can automatically spread fill from existing terrain by pressing a button. The dozer measures the terrain it tracks over, using the gathered data to plan the next pass. This functionality can lead to up to double the production and consistent layers for high-quality compaction.
Tilt Steering Control: Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing, reducing operator steering input by up to 80%. This feature ensures level material even in challenging conditions.
Quick Surface Creation: Operators can create a temporary design surface with a simple button press. When combined with other Intelligent Machine Control (IMC) 2.0 functions, the crew can initiate stripping or spreading using automated input while waiting for the finish grade model.
Closing the Operator Skill Gap: Machine logic allows the dozer to continuously learn the terrain, making calculated decisions for the next pass. Intelligent Machine Control helps narrow the skill gap between new and experienced operators.
Advanced Machine Control: In select situations such as auto stripping, rough dozing, spreading, and advanced finish grading, operators can opt for nearly 100% machine control auto usage. The system even allows for automatic control application.
Outstanding Blade Response for Finish Grading: Intelligent Machine Control (IMC) enables the dozer to anticipate grade transitions and adjust the blade angle accordingly, delivering exceptional blade response for precise finish grading.
