Lifting Shackles are designed for connecting and securing components together for use in a lifting, pulling or tensioning application. Each shackle is rated to a particular safe working load (maximum capacity) this should never be exceeded.
To connect a component using a lifting shackle firstly you will need to open the jaws of the shackle by removing the screw collar pin, the screw collar pin may also in some cases be protected by a safety pin and safety bolt, most of the time it is a simple case of turning the screw collar pin anti clockwise and it is released. Should this not be the case then remove the safety clip, unscrew the safety nut then remove the screw collar pin.
The second stage is to connect the components together and secure them by replacing the screw collar pin and if applicable; safety nut and clip. A Lifting Shackle is supposed to be used in a straight pull however they are rated to be used up to 90 degrees however one should be aware that when side pulling with a Lifting Shackle the safe working load is reduced by 50%. The screw collar pin should also never be mounted in a way that it could be unscrewed unintentionally.
It usually goes without saying but one should also never use a damaged or worn shackle as this could risk a serious injury and always use fully certified CE Lifting Shackles.
