Construct any building involves large capital equipment and materials which often must be lifted, pulled, or lowered to their final place in the project. A useful component of this operation is the shackles. Shackles come in various sizes, types, and load ratings making them a small but important tool on any job site.
For example, when a lift with the use of crane rigging anchor shackles often the endpoint of attachment. Tasks such as lifting a large culvert may employ using a nylon sling wrapped around the pipe and then attached to the shackle.

In this particular operation removable shackle pin to be used because of the nature of the nylon sling with eyes fixed end. Anchor shackle pin is removed, the eye of the lifting sling shackles and pins inserted is then replaced.
A shackle does not need a crane to be useful either. For example, say a forklift became stuck in the mud and had to be pulled out by a bulldozer or other equipment. Upon inspection of the forklift's frame was found that there was a place to pass through the chain was also no place to insert the hook.
However, there are a few round holes along the edges of the frame. A good way to fix this problem is to select the appropriate size screw shackle pin and insert the pin through the hole and fasten it to the bottom frame. Now you have the attachment point for connecting chains and forklift recovery from the mud.
