Shark Jaw

Marine shark clamps are heavy-duty deck-mounted devices used on ships and offshore vessels to secure and handle large chains, ropes or towing lines during mooring, anchoring or towing operations. Designed to withstand forces, shark clamps clamp and lock ropes to prevent slipping, ensuring safe and stable operation even in harsh sea conditions. It plays a vital role in anchoring operations, securing anchor chains or wire ropes during transfers between the ship and the seabed anchor. Marine shark clamps are usually made of high-strength, corrosion-resistant materials such as marine-grade steel, capable of withstanding the high loads and pressures brought on by offshore and deep-sea operations. They usually have an automatic locking mechanism that engages when the rope is inserted, ensuring fast and safe clamping without manual intervention. Some models are integrated into combined units with towing pins and retractable elements to improve deck safety and operational efficiency. Shark clamps are designed to meet international safety and classification standards, ensuring reliable performance in demanding environments. Its rugged design makes it an essential equipment for anchor handling, towing and deep-sea operations such as offshore supply vessels, anchor handling tugs and other specialized vessels.
