Bow shackle is a high‑strength connecting rigging device commonly used in lifting and hoisting, equipment towing, and ship mooring operations; it is also frequently referred to as a bow‑type shackle or a forged shackle. Compared with D‑shaped shackles, its large‑radius, arc‑shaped opening offers greater compatibility, allowing simultaneous attachment of multiple wire ropes, slings, and chains. It distributes loads evenly, minimizing the risk of crushing or damage to the rigging, making it an essential component for multi‑leg lifting systems and heavy‑equipment hoisting. It is widely suited to a variety of heavy‑load applications, including industrial infrastructure, port and marine operations, wind power, and mining.
This series of bow shackle shackles is manufactured in strict compliance with the national standard GB/T 25854, the U.S. standards G209 and G2130, and the European standard EN 13889. They are forged as a single piece from high‑strength alloy steels—40Cr and 35CrMo—eliminating any welded joints or seams. The products undergo quenching followed by high‑temperature tempering to achieve optimal mechanical properties, delivering exceptional toughness, impact resistance, and wear durability. This design effectively prevents brittle fracture and deformation under heavy loads and low‑temperature conditions, with a safety factor ranging from 4 to 6 times—far exceeding industry minimum requirements. To suit diverse operating environments, the products are available with a variety of surface treatments, including electro‑galvanizing, hot‑dip galvanizing, Dacromet coating, and stainless steel finish, making them suitable for indoor dry conditions, outdoor open‑air applications, marine corrosion, and humid chemical‑process environments.
Our product lineup offers a comprehensive range of specifications, covering the full tonnage spectrum from 0.5 t to 500 t, and is available in two mainstream designs: spiral pins and bolt‑type safety pins. The spiral‑pin bow shackle is easy to assemble and disassemble, delivers excellent value for money, and is well suited for routine applications such as light‑duty lifting, temporary material handling, and stage construction. The bolt‑type safety pin features a dual‑locking mechanism—comprising a nut and a split cotter pin—that effectively prevents pin loosening under heavy‑load vibration, ensuring superior safety and stability. It is the preferred choice for bridge engineering, ship mooring, wind‑turbine lifting, and long‑term heavy‑load operations, while also supporting large‑capacity wide‑body configurations and custom non‑standard specifications.
All products in the entire product line undergo magnetic particle nondestructive testing, rated‑load testing, and breaking‑tensile‑strength verification prior to shipment. Each item is stamped with clear markings indicating its capacity, rated load, and specification parameters, ensuring permanent traceability. We can provide quality inspection reports, CE certification, material certificates, and relevant classification society approvals, meeting the requirements of domestic engineering tenders as well as international export markets. Leveraging core advantages such as high strength achieved through integral forging, excellent versatility of the opening, secure locking to prevent slippage, and superior corrosion resistance and durability, our products effectively reduce risks in lifting operations and extend the service life of rigging components.
Our products are widely used in applications such as steel‑structure lifting in construction, tower‑crane foundation work, port‑terminal mooring, ship‑handling and crane operations, wind‑turbine tower installation, mining and metallurgical industries, and the relocation and traction of heavy equipment. All items are readily available in stock with fast shipping, and we also offer tailored one‑on‑one product selection guidance, custom non‑standard solutions, bulk‑order discounts, and other comprehensive services to fully meet the safety‑critical lifting needs of diverse industrial sectors.
