An anchor chain winch is a mechanical device used to deploy and retrieve anchor chains on ships. Anchor chains are heavy-duty chains that connect the anchor to the vessel, providing strength and weight for secure mooring. The winch ensures controlled handling of the chain during anchoring operations.

Anchor Chain Winch:
- Size: Typically 12mm to 150mm diameter
- Grade: Grade 2, Grade 3, or High-Tensile (HT) steel
- Material: Carbon steel or alloy steel
- Working Load: 5 tons to 500 tons
- Speed: 5 m/min to 15 m/min
- Power Source: Hydraulic, electric, or diesel-driven

Anchor Chains:
