Constructing a building of any kind involves big equipment and big materials that often must be hoisted, pulled or lowered to their final place in the project. A useful component of these operations is the shackle. Shackles come in a variety of sizes, types and load ratings thus making them a small but important tool on any jobsite.
For example, when rigging a lift with the use of a crane an anchor shackle is often the final point of attachment. Tasks such as hoisting a large culvert might employ using nylon slings that wrap around the pipe and the eyes are then attached to the shackle. In this particular operation a removeable pin shackle would be used because of the nature of nylon sling with a fixed eye end. The anchor pin of the shackle is removed, the eye of the lifting sling is inserted into the shackle and the pin is then replaced. A screw pin or round pin shackle works well for this task.
A shackle doesn’t need a crane to be useful either. It can be handy when other types of connections, such as a chain or hook, cannot be used because the attachment point will not allow enough room for a chain or hook. For instance, let’s say a forklift becomes stuck in the mud and must be pulled out by a bull dozer or other equipment. Upon inspection of the forklift’s frame it is found that there is nowhere to pass a chain through nor is there a place to insert a hook. However there are some round holes along the edge of the frame. A good way to fix this problem is to select an appropriate size screw pin shackles and insert the pin through the frame hole and tighten it down. Now you have an attachement point to hook a chain and recover the forklift from the mud.
