Product advantages
Powerful digging force:
The Komatsu mining bucket is equipped with an advanced high-power hydraulic drive system, which, combined with an optimized transmission structure, can unleash amazing digging power. It can easily "break through the ground" in the face of extremely hard rocks such as granite and basalt in mines, or hardened deep soil in large infrastructure projects. The strong digging force not only improves the efficiency of a single operation, but also reduces the number of repeated digging. In scenarios such as open-pit coal mining and large-scale port infrastructure construction, it effectively shortens the construction period, reduces equipment operation energy consumption and overall construction costs.
Excellent digging force of the bucket arm:
The arm of the PC4000 bucket is forged with high-strength alloy steel and has a unique mechanical structure design that gives it excellent excavation performance. In narrow lanes, urban subway construction and other space-constrained working environments, the arm can exert force accurately and dig materials deep into the gaps; in complex terrain, such as slope excavation during mountain road construction, it can also apply force stably to ensure smooth and efficient excavation. The excellent arm excavation force greatly enhances the adaptability and operating ability of the equipment under special working conditions.
Large bucket capacity:
The Komatsu mining bucket has a large-capacity design that far exceeds similar products, and the single loading capacity is significantly increased. Whether it is transporting bulk materials such as coal, sand and gravel, or moving earth and stone, it can carry more at a time and reduce the number of round-trip transportation. Taking large open-pit mines as an example, when transported with mining trucks, the PC4000 bucket can greatly improve loading efficiency and increase overall transportation throughput; in earth excavation operations of large-scale water conservancy projects, it can also speed up construction progress and help projects advance efficiently.
The maximum digging depth can reach 8000mm:
The maximum excavation depth of Komatsu mining bucket is 8000mm, which makes it stand out in ultra-deep excavation operations. In projects such as deep foundation pit excavation of large water conservancy hubs and deep excavation of subway tunnels, the PC4000 bucket can meet the design requirements and complete deep excavation in one step, avoiding the trouble of secondary construction due to insufficient excavation depth. With this advantage, it greatly improves the accuracy and efficiency of engineering construction and becomes the preferred equipment for projects requiring deep operations.
Work Scene
Open pit copper mining:
In open-pit copper mining, the Komatsu mining bucket has become a key mining equipment with its powerful digging force and large-capacity design. Copper mining often faces complex rock formations and hard ores. The PC4000 bucket can easily crush and dig, and efficiently strip the overburden and ore body. Its large capacity reduces the number of loading times, and with large mining trucks, it can quickly transport ore to the crushing station, ensuring the efficient operation of the entire copper mining process.
Open pit mining of iron ore:
Open-pit iron ore mining is a harsh operating environment with high ore hardness and large-scale mining. The PC4000 bucket meets the challenge with high-strength wear-resistant materials and excellent excavation performance. It can accurately excavate hard iron ore, and in large-scale ore stripping operations, it can efficiently remove topsoil and waste rock to quickly expose the ore body. At the same time, the large-volume bucket greatly increases the single loading capacity, and works closely with the transportation fleet to speed up the ore transfer speed.
Large-scale open-pit coal mining:
Large-scale open-pit coal mining requires extremely high equipment efficiency and reliability, and Komatsu mining bucket has its advantages in this scenario. Coal mining operations are large-scale and last for a long time. Its powerful digging force can quickly dig soft or hard coal seams, and can easily cope with complex coal seams mixed with gangue. The large-capacity bucket with a long operating radius can load more coal at a time, reduce round-trip transportation time, and work efficiently with dump trucks.
Large reservoir construction:
The bottom cleaning and excavation work of large-scale reservoir construction is arduous, requiring the handling of large amounts of earth and stone and complex geology. With its large excavation depth and strong excavation force, the PC4000 bucket can accurately excavate and level the reservoir bottom. It can efficiently remove silt, rocks and debris from the reservoir bottom, excavate to the specified depth according to design requirements, and ensure that the reservoir water storage space meets the standards.
Mine ventilation shaft excavation:
The excavation of ventilation shafts in large open-pit mines requires strict precision and efficiency, and Komatsu mining bucket plays an important role in this. Ventilation shafts need to be deep underground, which requires extremely high excavation depth and verticality. The PC4000 bucket has a maximum excavation depth of 8000mm and precise control performance, which can strictly perform excavation operations according to design standards and create a safe environment for underground workers.
Railway construction:
The road cutting excavation project in railway construction is large-scale and requires high precision, and the PC4000 bucket has become the main force in the construction. Road cutting excavation requires the processing of a large amount of earth and stone, and the excavation slope and depth must be strictly controlled. With excellent excavation performance and precise control, the PC4000 bucket can quickly remove surface earth and rocks, and can also operate stably in complex terrain to ensure the stability of the road cutting slope.
Maintenance system
Reasonable layout of maintenance points:
The maintenance point layout of Komatsu mining bucket adopts a centralized modular design concept, dividing key maintenance components into three modules: power system, hydraulic system, and working device.
The innovative maintenance point of the working device is reflected in the bucket connection part, which adopts a detachable maintenance channel design. The operator can directly reach the key parts such as the bucket pin and the bucket arm connection point through the hydraulic lifting platform. With the LED lighting system and the 360° rotating workbench, the single bucket pin lubrication operation time is reduced from 45 minutes of traditional models to 18 minutes. This layout method has been used in a large iron mine in Inner Mongolia, reducing the monthly maintenance hours of the equipment by 37%, effectively improving the equipment attendance rate.
Automatic lubrication system:
The automatic lubrication system managed by the Centurion control system on this model adopts a dual-pump four-zone independent oil supply architecture.
The lubrication system is equipped with an intelligent diagnostic function. When the lubrication pressure in a certain area is detected to be lower than 1700PSI, the system automatically starts the oil replenishment procedure and records the fault code. In the application of high-altitude mining areas in Tibet, the system adjusts the lubrication cycle to compensate for the change in grease viscosity caused by the low temperature environment, ensuring that the equipment can continue to operate stably in an environment of -25℃. Maintenance personnel can monitor the lubrication status of each area in real time through the 7-inch LCD screen in the cab, and quickly locate the problem point with the help of the fault code.
On-board fault monitoring system:
Komatsu mining bucket is an on-board monitoring system that integrates CAN bus technology. It can collect 237 parameters such as engine speed, hydraulic oil temperature, bucket digging force, etc. in real time.
Yellow warning: triggered when the parameter deviates from the normal value by 10%, prompting attention to the component status
Orange alarm: Activated when the deviation reaches 20%, automatically adjusts the working mode of related systems
Red shutdown: When the deviation exceeds 30%, a protective shutdown is executed to prevent the fault from expanding.
The system has a historical data storage cycle of up to 18 months, and with Komatsu's Komtrax remote monitoring platform, predictive maintenance of equipment health status can be achieved. In the practice of Australian iron ore, by analyzing historical data to optimize the maintenance cycle, the equipment overhaul interval was extended to 12,000 hours, 40% higher than the traditional model.
