What is the minimum number of chains recommended for a shotgun coil?

The minimum number of chains recommended for a shotgun coil is four. This requirement is based on safety regulations and best practices in load securement to ensure the stability and security of the load during transportation. Shotgun coils, typically being heavy and potentially hazardous loads, necessitate robust securing methods to prevent any movement that could result in accidents or damage.

Using four chains ensures that the load is effectively restrained in all directions. It distributes the forces acting on the load more evenly and minimizes the risk of the chains becoming overloaded. Adequate chain use is crucial, particularly considering the dynamic forces that can be exerted during transit such as acceleration, braking, and turning.

In contrast, fewer chains might not provide sufficient security, increasing the chance of the load shifting, and thereby compromising safety. The guidelines emphasize the importance of securing heavy or bulky items appropriately, highlighting the necessity for four chains in the case of a shotgun coil.
