The bucket material is made of high-strength wear-resistant steel, which can resist long-term wear under harsh working conditions and ensure that the equipment maintains stable operating performance in complex environments.
5. Enhanced bucket tooth structure to improve crushing capacity
The bucket teeth are made of high-strength alloy steel, and the cutting and crushing capabilities are improved through optimized tooth shape design.
At the same time, the bucket teeth can be disassembled and replaced, which is easy to maintain, reducing downtime and maintenance costs. Its superior durability ensures that the bucket maintains optimal performance in long-term high-intensity operations, further extending the service life of the bucket.
6. Strong adaptability, can be used in complex working conditions such as hard rock and clay
The DX800 excavator bucket has strong adaptability due to its high-strength material, optimized structural design and excellent wear resistance, and can easily cope with various complex working conditions such as hard rock and clay.
In hard rock environment, the bucket's impact resistance and Doosan excavator bucket tooth crushing ability ensure efficient operation, while in high-viscosity soil such as clay environment, the anti-stick design of the bucket inner wall can effectively reduce soil adhesion and improve unloading efficiency.
STONE BRAND - Structural optimization
1. Reinforced side plate design to reduce deformation risk
Technical improvement: The thickness of the side plate is increased by 15%, and a wave-shaped reinforcement rib layout is adopted to disperse stress concentration.
Application effect: In iron ore mining, the side plate's deformation resistance is increased by 30%, and there is no visible deformation after 200 hours of continuous operation.
Maintenance suggestion: Check the side plate weld every 500 hours to avoid crack expansion.
2. Arc-shaped bottom plate to optimize material flow and reduce adhesion
Fluid mechanics design: The bottom plate curvature radius matches the material throwing trajectory, and the unloading angle is optimized to 55° to reduce clay/wet sand residue (residue is reduced by 40%).
Case data: In river dredging operations, the single Doosan excavator bucket unloading time is shortened by 2 seconds, and the number of cycles per hour is increased by 8%.
Surface treatment: Polishing after laser cutting to reduce the friction coefficient.
3. Reinforced bucket lugs to ensure long-term operation without damage
Material upgrade: The lugs are made of Q690D high-strength steel, and the welding area is preheated to increase fatigue strength by 50%.
Structural optimization: A triangular reinforcement plate is added at the connection between the lug and the Doosan excavator bucket body, and the measured tensile load reaches 800 kN (the industry average is 600 kN).
Test data: In the 24-hour continuous operation test, the lugs did not move or crack.
4. One-piece reinforcement plate structure to improve overall impact resistance
Technology innovation: The back of the Doosan excavator bucket adopts an integral forged reinforcement plate (rather than traditional segmented welding) to eliminate the weak points of the weld.
Impact test: Under the simulated impact of 25 tons of falling rocks, the deformation is only 3.2mm (8.5mm for the split structure).
Lightweight design: 12% weight reduction through topological optimization, while the rigidity is increased by 18%.
STONE BRAND - Durability
The DX800 excavator bucket is made of high-strength wear-resistant steel to ensure that the bucket has excellent durability in high-load operations.
The use of high-strength steel greatly improves the bucket's wear resistance, especially when handling high-wear materials such as ore and hard rock, which can effectively reduce the loss of the Doosan excavator bucket and extend its service life. In addition, the high toughness of wear-resistant steel can also reduce cracks or deformation caused by impact, ensuring that the bucket maintains stable performance under harsh working conditions and reducing replacement and maintenance costs.
In the bucket structure design, additional reinforcement is carried out for high-stress areas to effectively prevent stress concentration cracking caused by long-term use.
For example, the bucket side plate, connecting ear plate and bucket tooth installation parts are all made of extra thick high-strength steel plates, and the stress distribution is more uniform through special structural optimization.
This reinforced design not only extends the life of the bucket, but also improves the stability of the operation, so that the Doosan excavator bucket can still maintain a good working condition when facing high impact loads.
The bottom of the bucket is the part that directly contacts the ground and bears the greatest friction, so the DX800 bucket adopts a thickened bottom plate structure to enhance its wear resistance.
By selecting high-strength wear-resistant plates and adding reinforcing rib structures, the bottom of the bucket not only has stronger wear resistance, but also can effectively buffer the impact from rocks or hard soil layers, reducing structural damage caused by long-term wear.
This design greatly improves the service life of the bucket under extreme working conditions such as mines and quarries.
The bucket angle design of the bucket directly affects its durability and operating efficiency. The Doosan excavator bucket has been finely optimized. While ensuring the digging force, the bucket angle is reasonably adjusted to reduce lateral wear of the bucket during digging and unloading.
In addition, the optimized bucket angle can also reduce operating resistance, making it easier for the bucket to cut into soil or rocks, reduce fuel consumption, and improve the overall working efficiency of the equipment.
This optimized design ensures that the bucket can operate stably for a long time in a high-intensity working environment, effectively reducing maintenance costs.
STONE BRAND - Operation efficiency
1. Optimized bucket design to improve loading rate
DX800 excavator bucket adopts optimized bucket design, and the bucket wall curve is precisely calculated to make the material flow more smoothly during loading, reduce material resistance and improve loading efficiency.
The wide opening design and optimized inclination angle enable the Doosan excavator bucket to fill quickly, maximizing the single loading volume.
At the same time, it reduces material spillage, improves loading accuracy, and further improves operation efficiency. This optimized design is particularly important in large-scale earthwork operations and mine construction, which can effectively reduce loading time and improve overall work efficiency.
2. Increase single excavation volume and reduce repeated excavation
The capacity optimization design of the DX800 bucket enables it to load more materials in each excavation, thereby reducing the number of repeated excavations and improving operation efficiency.
The Doosan excavator bucket structure ensures that the material is filled to the maximum during each excavation, reducing empty loads and ineffective operations. Especially in mines, quarries and large-scale earthwork projects, reducing unnecessary repeated operations can not only improve work efficiency, but also reduce fuel consumption and equipment wear, and extend the service life of the whole machine.
3. Suitable for large-scale earthwork projects and improve construction efficiency

FAQ
1. How comfortable is the cab of Doosan excavators?
The cab design of Doosan excavators focuses on operator comfort and operating efficiency:
1. Vision design and space layout
The cab of Doosan excavators uses large-size glass and 360° blind spot design to greatly reduce blind spots. For example, DX75 and DX80 share the same-level cab. By expanding the glass area and optimizing the structure, the blind spots are minimized to ensure that the operator can clearly observe the surrounding environment919.
Some high-end models (such as DX680H) also come standard with a 360° camera system to further expand the field of vision coverage, especially in complex working conditions.11.
2. Ergonomics and comfort configuration
The interior of the cab adopts ergonomic design, and the seat supports multi-directional adjustment and is equipped with suspension shock absorption function. For example, the luxurious multi-functional suspension seat of DX340LC-9C can relieve fatigue after long-term operation, and is equipped with an automatic temperature control system to ensure comfort in winter and summer1719.
In addition, the DX680H cab is equipped with a touch-screen instrument panel, keyless start and a car-level remote control key, making it as easy to operate as a passenger car11.
3. Noise reduction and shock absorption technology
By optimizing the cab sealing and sound insulation materials, the noise level of Doosan excavators has been significantly reduced. For example, in the comparison test of Hyundai R215VS, the cab noise of Doosan DX215-9C was 30% lower than that of the old model, and the vibration control technology also extended the service life of the shock pad19.
Some models are also equipped with independent radiators and reversible cooling fans to reduce external noise interference17.
4. Intelligent interaction and control optimization
The cab integrates intelligent control systems, such as the high-definition LCD display of DX215-9C, which can monitor the equipment status and operating parameters in real time and improve operating efficiency19.
The handle spacing and angle have been scientifically adjusted (such as the improved design of Hyundai R215VS) to reduce operating fatigue19.
2. How is the second-hand market value retention rate of Doosan excavators?
Doosan excavators have a high value retention rate in the second-hand market, and its core advantages are reflected in brand, market ownership and after-sales service:
1. Brand and technology accumulation
As a joint venture brand, Doosan has established a reputation for high durability and low failure rate among users with years of technology accumulation and mature processes (such as original imported engines and hydraulic systems).
For example, the failure rate of core components of DX340LC-9C (such as DL08 engine) is much lower than that of similar products, which directly increases the second-hand value by 1714.
2. Market ownership and regional differences
Doosan has a large number of units in the domestic market, especially small and medium-sized models (such as DX60, DX215-9C) with strong liquidity. Second-hand platform data shows that the listing price of DX60 (4000 hours) in good condition is stable in Beijing, and the car viewing report shows that its mechanical parts have a low degree of wear 818.
In addition, regional market demand varies significantly. For example, the northern region has a higher recognition of Doosan, which further pushes up the value retention rate1418.
3. After-sales service and maintenance cost
Doosan provides a complete after-sales network and parts supply system to reduce the subsequent maintenance cost of second-hand equipment.
For example, the easy-to-maintain design (centralized maintenance points) and extended filter replacement cycle of DX215-9C reduce the long-term use cost and indirectly support the second-hand price1917.
4. Comparison with competitors
Compared with domestic brands such as Sany, Doosan has more advantages in the second-hand market. User feedback shows that the second-hand Sany 135 of the same tonnage has a higher failure rate and more expensive parts cost, while Doosan 150 is more popular because of its strong power and durability1814.
Although first-line brands (such as Komatsu and Carter) have a higher value retention rate, Doosan has an advantage in the mid-range market with its cost-effectiveness20.
3. What is the environmental performance of Doosan excavators?
The Volvo 950 bucket uses high-strength wear-resistant materials (such as HARDOX wear-resistant plates) to effectively resist the wear of highly abrasive materials. The key parts of the bucket (such as the bottom plate, side plates and blades) have been thickened to further enhance durability and impact resistance. In addition, the bucket is equipped with wear-resistant guards and corrosion-resistant coatings to effectively prevent damage from humidity and chemicals and extend its service life.
4. What is the approximate transportation and logistics cost of Doosan excavators?
The transportation and logistics costs are greatly affected by the tonnage of the machine, the transportation distance and the policy, and need to be discussed separately:
1. Large mining models (such as DX680H, DX1000LC-7)
Weight and size: The DX680H has a total weight of 64.1 tons and a chassis width of 3900mm. It requires a heavy-duty trailer and special transportation permit11.
The transportation cost of such equipment is usually 30,000-50,000 yuan/time (within 500 kilometers), and long-distance transportation (such as across provinces) may be as high as 100,000 yuan or more.
Loading and unloading and insurance: Professional lifting equipment is required, and the loading and unloading costs are about 5,000-10,000 yuan; high-insurance transportation insurance further increases the cost11.
2. Small and medium-sized models (such as DX60, DX215-9C)
Conventional transportation: 20-ton models (such as DX215-9C) can be transported by standard flatbed trucks, and the cost within 500 kilometers is about 10,000-20,000 yuan. For example, the cost of transporting a second-hand DX60 from Beijing to surrounding provinces is about 8,000 yuan819.
Policy restrictions: Some cities have restrictions on the entry of construction machinery into the city, requiring night transportation or applying for a pass, which adds additional costs.
3. Regional differences and seasonal factors
Remote areas: Due to complex road conditions in Xinjiang, Yunnan and other places, transportation costs may increase by 30%-50%58.
Peak season impact: During the peak construction season (such as spring), transportation demand surges, and prices may temporarily increase by 20%18.
