The composition of the anchor chain（1）

Anchor chain link（anchor chain)
Chain link in anchor chain includes common link (c), enlargedlink (EL), open end link (E), swivel (SW), D type end shackle (ES), connecting link (KS) or connecting shackle (JS), etc. The size of each link is represented by the round steel diameter of the link, as shown in Figure 2.

Ordinary chain link(anchor chain) is the chain link that accounts for the majority of the anchor chain. It is a standard chain link that represents the size and strength of the anchor chain. The size of the anchor chain is expressed in chain diameter (mm), and chain diameter (d) is the diameter of ordinary links in the corresponding anchor chain. The size ratio of the ordinary chain link with gear is: diameter D, width 3.6d and length 6D. The enlarged chain link mainly plays the role of size transition in the anchor chain, and its size is 10% higher than that of the ordinary chain link with gear in the corresponding anchor chain. The end link is an enlarged open link in the anchor chain, which is used to cooperate with the connection of other links and play the role of size transition. Its diameter is 1.2D.
