Product Features
Self-Sharpening Design
The 28DS12AP Draghead Pick Point Tooth features a self-sharpening profile that maintains a sharp edge during operation. This design minimizes energy loss and reduces fuel consumption while improving excavation performance, especially in compacted or rocky seabeds.
Optimized Geometry
Its pick-style tip with narrow geometry ensures better ground penetration and material fracture, significantly increasing productivity in hard rock dredging applications. The design also helps reduce vibration, offering smoother operational efficiency.
Universal Compatibility
Compatible with multiple adapter systems such as ESCO and VOSTA IHC, the tooth ensures versatility across different dredging equipment. This universal fit allows end-users to simplify their inventory and reduce downtime during replacement.
Enhanced Heat Treatment
County Line's dredging teeth are made from a proprietary alloy steel and undergo advanced heat treatment processes. This enables the tooth to achieve a perfect balance between hardness and toughness which resists deformation and premature wear even in the most extreme dredging conditions.
Maintenance
Regular Inspection Schedule
To maximize performance, it's recommended to inspect the wear pattern every 80–100 operational hours. Replace if more than 70% of the tip is worn to prevent secondary damage.
Corrosion Prevention
Store unused teeth in dry environments and apply anti-rust oil on metal surfaces during long-term storage. This ensures longevity and readiness when needed.
Cleaning After Use
Clean the tooth surface and locking area after every operation, especially in saltwater environments, to prevent material build-up that can cause misalignment.
Lubrication and Rotation
Grease the pin-locking system regularly and rotate tooth positions (if applicable) to achieve uniform wear. This small step greatly extends usable life.
Precautions for Use
Proper Tooth Selection
Ensure the correct tooth type is selected based on the seabed condition. For rock layers, the 28DS12AP Draghead Pick Point Tooth is optimal. Using the wrong type may result in premature breakage or inefficient dredging performance.
Secure Installation Practices
Always follow the specified torque values and locking procedures during installation. Improper fitting may lead to tooth dislodgment during operation, increasing safety risks and equipment downtime.
Avoid Overloading
Monitor machine pressure and vibration levels. Overloading the dredging equipment may cause microfractures in the alloy, shortening the service life of the tooth even with premium materials.
Replace Worn Components
Avoid using excessively worn adaptors or pins with new teeth. This mismatch can lead to unstable engagement, accelerated wear, or even loss of the 28DS12AP Draghead Pick Point Tooth during use.
FAQ
Q: Which countries do you ship to?
A: We have exports set up with more than 50 countries, including: USA, Canada, Germany, Australia, South Korea, and UAE. Shipping is available globally.
