Operating practices and guidelines for the use of shackles are as follows:
- The shackle pin shall never be replaced with a bolt; only a properly fitted pin shall be used. Bolts are not intended to take the load that is normally applied to the pin.
- Shackles shall not be used if the pin cannot be completely seated.
- Shackles shall never be pulled at an angle because the capacity will be tremendously reduced. Centralize whatever is being hoisted on the pin by suitable washers or spacers .
- Screw pin shackles shall not be used if the pin can roll under load and unscrew.
