Factory Supply SPEK High Holding Power Anchor Cast Steel Marine Ship Anchor
Product Overview
The Spek anchor is the mainstream type of stockless anchor featuring sturdy structure, convenient operation, reliable grip, and strong adaptability. Widely used in merchant ships, engineering vessels, cruise ships, and yachts, it is suitable for various seabeds including sand, mud, and gravel. Available in Type 95, Type SR, and Type M models covering weight requirements from 40kg to 26,000kg.
Key Material Advantages
- Stable Pulling Force: Reliable performance on regular seabeds (sand, mud) meeting daily anchoring needs with high cost-effectiveness
- Easy Operation: Cross-bar free design simplifies retraction, storage and reassembly processes
- Low Maintenance Cost: Durable cast steel structure with adequate surface protection treatment
Manufacturing Process
Production follows CB/T 711-1995 standards and classification society requirements through comprehensive manufacturing stages:
- Raw Material Preparation: Selection of ZG200-400C, Q235 shipbuilding cast/forged steel with spectral analysis and mechanical property testing
- Forming Process: Casting (mainstream for large specifications) or forging (high-strength requirements) with controlled temperature and composition
- Heat Treatment: Normalizing at 880-920°C, optional quenching, and tempering at 550-650°C for optimal performance
- Finishing & Size Control: CNC machining with ±1-±3mm tolerance, three-coordinate measurement verification
- Surface Treatment: Sandblasting followed by hot-dip galvanizing (≥85μm) or multi-layer coating system (≥200μm)
- Assembly & Testing: Comprehensive safety verification and quality control
