The End Link is a specialized connecting component used in anchor chain systems. It serves as a transition fitting between the enlarged link and the end shackle or swivel within an anchor chain assembly. The End Link is an open-type link with enlarged diameter. Its size ratio is 1.2d, where d represents the diameter of the common link.
Surface finish options include black bitumen coating and hot dip galvanized. Material grades available are U2 for standard applications and U3 for higher tensile strength requirements.
It also serves as the terminal fitting for anchor chains in buoy mooring systems. In marine vessel anchoring, it connects anchor chain to end shackle.
The typical assembly sequence for a five-ring Swivel Forerunner is: C + EL (enlarged ring) + SW (rotary ring) + EL (enlarged ring) + E (end ring) + AS (anchor shackle).
Frequently Asked Questions:
Q1: What is the difference between an End Link and an Enlarged Link?
The End Link is a terminal connection fitting used at the chain end to connect to shackles or swivels. The Enlarged Link is an intermediate transition link placed between common links or next to the end link. The End Link has a size ratio of 1.2d while the Enlarged Link has approximately 1.1d. The End Link is always open type and used at the chain terminal.
Q2: What is the difference between Grade U2 and Grade U3?
Grade U2 is standard marine grade suitable for most commercial vessels. Grade U3 has higher tensile strength and is designed for larger vessels and harsh marine conditions. Always match the end link grade with your anchor chain grade for optimal performance.
Q3: Which surface finish should I choose?
Black bitumen coating is cost effective and provides standard marine protection for general environments. Hot dip galvanized offers superior corrosion resistance and longer lifespan, recommended for long term mooring in saltwater conditions.
Q4: Why is the End Link larger than standard chain links?
The End Link has a size ratio of 1.2d to accommodate connection to larger fittings like shackles and swivels. This enlarged design ensures proper fit, sufficient strength at connection points, and easy installation and removal of connecting shackles.
