Product Detail

Marine Roller Shackle – Heavy Duty Shackle For Lifting

A marine roller shackle is a heavy duty shackle specifically designed for lifting operations in marine environments. It incorporates a swivel mechanism that allows for rotation, minimizing the risk of twisting or tangling of lifting slings or cables.

The swivel feature of a lifting shackle, such as the marine roller shackle, is invaluable for lifting operations. By allowing free rotation, this type of heavy duty shackle minimizes stress on lifting slings or cables, effectively safeguarding the rigging system’s integrity. This capability prevents potential damage and significantly enhances safety during lifting operations. With improved load distribution and reduced strain, the lifting shackle ensures a secure and efficient lifting process, mitigating the risk of accidents or failures. Overall, the swivel functionality of the marine roller shackle plays a critical role in maintaining the structural integrity of the rigging system, promoting safety, and preventing any harm or damage.

Marine Roller Shackle Features

These expertly crafted roller shackles are drop forged and feature a hexagon bolt pin and nut, guaranteeing exceptional fastening capabilities. Available in a range of safe working loads (SWL), including 3 ton, 4 ton, and 5 ton, our marine roller shackles deliver unwavering strength for diverse cargo securing needs. The incorporation of a cotter pin hole adds an extra layer of reliability, effectively preventing nut loosening during demanding operations.
