Product Features

Self-Sharpening Chisel Design

The 28DS13AC features a self-sharpening chisel profile that helps maintain an aggressive cutting edge throughout its lifespan. This allows for consistent dredging efficiency and minimizes the need for frequent tooth replacement during long-term operations.

Composite Reinforced Tip

The working edge of the tooth includes a wear-resistant composite material to reinforce high-impact zones. This reduces premature wear, making it highly suitable for compact sand and clay dredging in demanding marine environments.

Precision Fit and Lock Compatibility

Designed with strict tolerance control, this tooth fits securely with adapters and locking systems from ESCO, ensuring safe, stable, and fast installation and removal during dredging equipment maintenance.

Corrosion-Resistant Alloy Steel

Made from premium alloy steel treated for anti-corrosion, the tooth resists both wear and rust even in saline or abrasive water conditions, helping extend its effective working life.

Maintenance

Scheduled Wear Inspections

Conduct regular checks for signs of excessive wear, especially at the chisel tip and locking interface. Early detection ensures safe and uninterrupted operations.

Cleaning After Use

After dredging sessions, clean the teeth to remove sediments and prevent corrosion. This is especially important for long idle periods or storage between projects.

Lubricate Locking Pins

Always lubricate the pin and locking system during installation to reduce friction and ease future removal. Avoid dry-fitting the tooth onto the adapter.

Safe Storage Conditions

Store unused or spare 28DS13AC teeth in a cool, dry place away from direct sunlight or corrosive environments to preserve material quality.

Product Advantages

Interchangeability with Global Systems

Fully compatible with widely-used cutterhead systems like ESCO and VOSTA, making it easy for global clients to integrate the 28DS13AC into their fleets without design changes.

Custom Branding and Color Options

We offer tailored color and logo customization on the 28DS13AC to meet brand consistency and project requirements, which adds professional value to your fleet.

Lower Operational Costs

Thanks to reduced tooth replacements, lower fuel usage, and less machine wear, total operational costs per project are significantly decreased.

Environmentally Friendly Manufacturing

Produced using low-emission foundry technology and recyclable alloys, our process supports sustainability goals in marine construction and infrastructure.

Increased Equipment Longevity

Stable, secure fitting of the tooth ensures lower vibration and mechanical shock, extending the lifespan of both the cutter teeth and the dredging machinery.
