The advantages of the endless chain loop are its relative light weight, ease of manufacture, versatility of connection to other components (e.g., shackles), and wide range of applications. Through stress analysis, when the non-stop ring is subjected to larger tensile stress, the ring body deforms greatly, the middle of the straight body part can be recessed inwards, the ring width size is reduced, the ring length size is increased, and jumping and even chain clamping can occur when an anchor machine or a chain wheel is crossed. Another problem of the endless loop is that, because there is no shielding in the middle, the endless loop is easy to twist when in use, so that the chain is twisted together, which also affects the use.
