High-tensile chain
A high-tensile chain, also referred to as a transport chain, is a link chain with a high tensile strength used for drawing or securing loads. This type of chain usually consist of broad (thick/heavy) metal, oblong torus-shaped links for high strength. All the links of the chain are usually identical, and on the ends are usually two hooks of the appropriate size and strength to slide easily over one chain link but small enough not let the links slip by. When the ability to grasp the load is required, a slip hook is used.
