What Is a Chain Hook?

The end of the anchor chain that is connected to the hull eye plate is called a decoupling link.

Decoupling link ^[3]

Anchor chain ^[2] is one of the main components of the anchoring device, and the grasping force of the anchor must be transmitted to the ship through the anchor chain. One end of the anchor chain is connected to the anchor, and the other end is fastened to the ship. Under the action of wind, tide, wave, and current, the anchor chain is formed as shown in FIG. 3.

Type and level

Anchor chain can be divided into two types: filed and non-filed. The filed chain is A type and the fileless chain is B type. Either with or without anchors can be welded, cast or forged. Anchor chains can be divided into three levels according to the tensile strength of the materials, namely M1, M2, and M3, which are respectively expressed as first, second, and third level anchor chain steel.

composition

Anchor chain is composed of ordinary chain link, enlarged chain link, end chain link, and shackle, swivel, decoupling and other components connected to the chain link. The ordinary link is used for intermediate links; the enlarged link is mainly used for the connection of the turn and the segment; the end link is mainly used for the end connection of the segment; the turn is mainly used for the connection of the anchor end chain, and its function It keeps the anchor chain from twisting. Shackles are divided into connection shackles (Kent shackles) and chain end shackles. The connection shackle is mainly used for the connection of the chain segment; the chain end shackle is mainly used for the connection with the anchor or the eye plate; the decoupling is connected with the chain link, and its function is for the delinking; the abandoner is in the anchor chain cabin Attached to the end link. The segments of the anchor chain are usually expressed as "links", and the length of one anchor chain is 27.5m, so that the total length of the anchor chain can be configured as an integer multiple of the length.
