It can fully meet the long-term heavy-duty operation requirements in various engineering construction scenarios, making it the optimal choice for equipment maintenance and parts replacement.
1. Compatible Models
Exclusively designed for Doosan DH220-5, DH220LC-7, DH220LL and other full series of DH220 excavators. All dimensional parameters are completely consistent with original parts, supporting direct installation and replacement without modification, effectively reducing installation and debugging costs and improving equipment operation and maintenance efficiency.
2. Core Product Parameters
1. Material: Selected high-strength 50Mn/40MnB alloy structural steel, formed by precision forging process with uniform material density, delivering excellent impact resistance and deformation resistance to guarantee basic product performance.
2. Heat Treatment: Adopting double heat treatment process of overall quenching & tempering plus gear part high-frequency quenching. The tooth surface hardness stably reaches HRC50-58, with a hardened layer depth of 8-12mm, balancing tooth surface wear resistance and core toughness, avoiding tooth surface cracking and root fracture.
3. Specification Details: Standard 21 teeth design with 30 precise positioning mounting holes, hole position deviation ≤0.05mm. The tooth profile is processed by precision CNC machining with high contour accuracy, ensuring tight and gapless meshing with the track chain.
4. Surface Treatment: Anti-rust blackening/painting treatment, effectively resisting erosion of muddy water and rainwater on construction sites, delaying rusting and aging, and prolonging product storage and service life.
3. Key Product Advantages
1. Superior Wear Resistance: Made of high-quality alloy steel with professional heat treatment, the tooth surface has far better wear resistance than ordinary parts. It can cope with harsh working conditions such as mines, quarries and rocky construction sites, greatly reducing failures like tooth wear, tooth loss and tooth breakage, extending replacement cycle and reducing operation and maintenance costs.
2. Perfect Fitment: Manufactured strictly according to original factory drawings, all dimensions, installation spacing and meshing accuracy meet OEM standards. After installation, it perfectly matches the travel motor and track system, running smoothly without jamming or deviation, eliminating problems of improper installation and poor meshing.
3. Stable & Efficient Transmission: Optimized tooth profile curve design ensures precise meshing with the track chain, realizing smooth and stable transmission, effectively reducing traveling vibration, noise and power loss, improving the response speed and operation efficiency of excavator traveling, steering and climbing.
4. Excellent Impact Resistance: The sprocket has outstanding overall toughness, capable of withstanding sudden impacts and heavy-duty rolling during construction, not easy to deform or break, adapting to continuous high-intensity operation mode and ensuring equipment working efficiency.
5. Reliable Quality Assurance: The product has passed multiple quality inspection procedures including dynamic balance test, wear resistance test and compression test, complying with ISO9001 quality management system standards, with stable and reliable performance and worry-free after-sales service.
4. Application Scenarios
Widely used in various heavy-duty and harsh operating environments, such as construction engineering, municipal construction, road construction, bridge construction, mining, earthwork engineering. Whether traveling on flat ground, climbing steep slopes, or operating in complex terrains, it can maintain stable and reliable operation, helping the excavator carry out continuous and efficient construction.
5. Product Value
Our DH220 excavator sprocket not only achieves the same performance experience as original parts, but also effectively reduces parts procurement costs, minimizes equipment downtime and maintenance time, and accelerates project construction progress. With excellent quality, perfect compatibility and cost-effective performance, it has become an ideal choice for engineering equipment maintenance and excavator repair, escorting the stable operation of equipment.
