Draglines are heavy excavation machines typically used in large-scale mining and civil engineering projects. They are known for their ability to move vast amounts of earth and rock efficiently. Draglines consist of a large bucket suspended from a boom and cables. The bucket is dragged or “dragged in a line” to excavate material, hence the name “dragline.”
Features of Komatsu Draglines (General):
- Bucket Capacity: Komatsu draglines are designed with varying bucket capacities to suit different applications. The size of the bucket influences the amount of material the dragline can handle in a single operation.
- Boom Length: The length of the boom determines the reach and depth of excavation. Longer booms allow the dragline to reach deeper into the excavation site.
- Powerful Motors: Draglines are equipped with powerful motors to move the bucket and handle the weight of excavated material.
- Operator Cab: The operator’s cab is designed for comfort and visibility, providing the operator with the necessary controls to manage the dragline’s operations.
- Automation: Modern draglines often feature automation and remote control capabilities for improved precision and safety.
- Structural Stability: Stability is crucial for large machines like draglines. Komatsu draglines are engineered for stability during operation.
- Efficient Material Handling: The efficiency of material handling is a key focus, ensuring that the dragline can move large quantities of material in a cost-effective manner.

Tub Engineered for Peak Performance: Constructed for extended longevity and minimal maintenance, P&H tubs adeptly manage multi-directional loads. Verti-shield welding securely connects all intersection plates through one continuous weld, resulting in minimal distortion, widely distributed loading, and low residual stresses.
Intelligent, Productivity-Focused Electronics: Monitor your machine’s performance to facilitate efficient operation and maintenance activities. The Centurion control system employs smart electronics to monitor dragline operations.
Highly Engineered Boom and A-Frame: Ensuring stability, the four-chord boom with a flat underside provides excellent visibility of boom point sheaves and balanced axial working loads. The A-frame is designed to minimize load forces for maximum-rated suspended loads.
Engineered with User Input: Whether advancing safety, delivery, or solutions that enhance your day-to-day maintenance and inspection activities, our aim is to assist you in achieving your goals for increased production, reduced downtime, and lower cost per unit moved.
Exceptional Service: At the core of our commitment to customers is collaboration to develop innovative parts, products, consumables, and systems designed to lower the total cost of ownership while optimizing production.
