Misconceptions

Misconception 1. If you have attended a training course you are a competent rigger.

Training is only one part of being competent to carry out your job, you must also be adequately qualified and have sufficient experience.

Misconception 3. The cotter pin of a bolt type shackle can be replaced with a spring clip or wire.

Repairs, alterations, or modifications shall be as specified by the shackle manufacturer or a qualified person. Replacement parts, such as pins, shall meet or exceed the original equipment manufacturer's specifications.

Misconception 4. A shackles marked size is the diameter of the pin.

This is most probably the most common misconception, the size marked on the body on the shackle referes to the diameter of the shackle body not the diameter of the pin, the pin in almost every case is greater in diameter than the body.

Misconception 5. Shackles can make contact with the load when lifting at angles.
