Shackles are among the most essential components in lifting and rigging operations. These forged metal connectors act as critical intermediaries between lifting equipment and the load, ensuring secure and reliable attachment during lifting tasks.
At Carl Stahl, we understand the importance of dependable shackles that meet rigorous industry standards. Whether you require shackles for crane lifting, load securing, or heavy-duty industrial use, we offer a comprehensive range of certified shackles tailored for safety, performance, and longevity.
Shackles are mechanical connectors typically made from high-strength alloy steel. They are used to create secure links between slings, chains, ropes, or lifting devices and the loads being hoisted.
Designed to handle significant tensile and shear forces, shackles must meet strict load-bearing criteria and safety regulations. Each type of shackle serves a unique purpose, ensuring compatibility across various lifting environments and conditions.
Choosing the right shackle is critical to the success and safety of your lifting operation. Shackles are available in various designs and configurations:
Bow shackles feature a rounded "O" shape, making them suitable for applications involving multi-leg slings or off-centre loading. They allow greater freedom of movement and are ideal for lifting scenarios where angular loads are present.
Dee shackles have a narrower "D" shape and are optimised for straight-line pulls. They provide a strong, stable connection and are commonly used in single-leg slinging.
These shackles feature a threaded pin for quick and easy attachment and removal. They’re ideal for temporary lifting tasks or where frequent adjustments are required.
Bolt-type shackles use a bolt, nut, and cotter pin to prevent accidental opening. They are the preferred choice for permanent or long-term lifting applications.
Designed with an integrated safety mechanism, these shackles are built for enhanced reliability in critical lifting tasks.
When safety, compliance, and load integrity matter, using certified shackles is non-negotiable. At Carl Stahl, all our shackles are:
Load Tested and Certified
Every shackle is tested in accordance with UK and international lifting regulations, including LOLER and EN standards.
Durable and Corrosion Resistant
Made from galvanised or stainless steel, our shackles are suitable for both indoor and outdoor environments.
Clearly Marked
Working Load Limits (WLL), batch numbers, and manufacturer IDs are stamped directly onto the shackle body for traceability.
Shackles are used across a wide variety of industries and applications:
Construction and Civil Engineering – For lifting beams, concrete elements, and equipment
Marine and Offshore – In mooring lines, rigging systems, and subsea lifting
Transport and Logistics – For cargo securement and recovery operations
Energy and Utilities – In wind turbine maintenance, power line work, and heavy infrastructure projects
Manufacturing – To handle dies, moulds, and machine parts
For optimal safety and performance, shackles must be regularly inspected and maintained:
Visually check for wear, cracks, deformation, and corrosion
Ensure the pin fits properly and is not bent or worn
Verify that WLL markings are visible and legible
Lubricate threads where applicable
Replace damaged shackles immediately
