Product Features
Versatile Tooth Designs
The 7GAF3 cutterhead teeth come in flare, chisel, and pick styles to suit different dredging environments. Each design is engineered to optimize performance in various soil types such as soft clay, sand, or even rock, maximizing efficiency during operation.
ESCO-Compatible Mounting System
This product features a special mounting geometry that ensures a perfect fit with ESCO-style adapters. The precision-matched interface reduces vibration and ensures stable, reliable operation under high-load conditions.
Precision Casting Technology
Manufactured using advanced precision casting, the 7GAF3 teeth offer uniform structure, tight dimensional tolerance, and excellent surface finish. This results in improved wear resistance and consistent performance during harsh dredging operations.
Customizable Finish & Branding
Customers can request specific colors (such as black, yellow, or green) and have their logo cast or printed onto the product. This OEM flexibility supports brand identity while ensuring seamless supply chain integration.
product advantages
Excellent Wear Life
The 7GAF3 cutter teeth are made from specially formulated wear alloy steel, enhancing abrasion resistance. This extends the operational lifespan, which reduces maintenance frequency and saves replacement costs over time.
Perfect Fit with Reduced Downtime
Thanks to the ESCO-compatible design, the teeth offer seamless installation and disassembly. This minimizes machine downtime during part replacement and improves overall dredging system efficiency.
Lower Operating Costs
The durability and reliability of the 7GAF3 teeth significantly reduce the costs related to spare part consumption, labor, and unexpected downtime.
Adaptability to Multiple Dredger Models
The product is compatible with a wide range of cutter suction dredgers and dredging wheels, offering broad application across marine infrastructure, river widening, and harbor maintenance projects.
Precautions for Use
Match Tooth Type with Soil Condition
Always use flare teeth like the 7GAF3 in soft soil environments such as peat and clay. Using the wrong tooth type may reduce productivity and damage equipment.
Secure Pin & Adapter Connection
Ensure the pin (such as 5678GL-B) is fully locked before starting operations. Loose fittings can cause tooth loss and endanger operators or surrounding components.
Avoid Overuse in Rock Conditions
These flare-type teeth are not suitable for rocky terrains. Overuse in such environments may lead to premature wear or breakage, voiding any product warranty.
Store Properly After Use
After cleaning, store the teeth in dry, covered areas to prevent rusting and maintain surface integrity. Use wooden crates or pallets for secure handling and inventory control.
