Lifting chains offer numerous benefits in various lifting and rigging applications. They provide exceptional strength, durability, and load-bearing capacity, making them suitable for heavy-duty lifting tasks. Lifting chains can withstand high tension and are resistant to wear, corrosion, and damage. They offer flexibility and adaptability, allowing for easy adjustment to accommodate different load sizes and shapes. Additionally, lifting chains are versatile, making them suitable for various industries and applications where safe and reliable lifting is required.
Alloy Chain Grade 80 or Grade 100 should be used for overhead lifting. ASTM states that alloy chain shall be able to elongate a minimum of 20% before fracture (7.3.5). To ensure that alloy chain consistently meets this requirement, ASTM requires the use of certain alloying elements in the manufacturing of the steel for alloy steel chain. These alloys can vary from company to company, but some key requirements are specified by ASTM. The alloy properties also improve the wear and tear that the chain will experience. Note that when chain is in use, no amount of stretch is allowed.
One of the safety measures implemented was to place chain in Grades based on the ultimate breaking strength of that chain. This number is what we see today G30, G43, G70, G80 & G100 and the common chain grades. The number after each letter is N/mm2. For example, G80 means that the maximum stress on the chain at ultimate strength is 800 newtons per millimeter squared.
Lifting chains are typically made from high-quality alloy steel, which provides excellent strength and durability. They consist of a series of interconnected links that form a continuous chain. Lifting chains are available in different sizes, grades, and configurations to match specific load requirements. They may feature different types of end fittings, such as hooks, shackles, or rings, for convenient connection to lifting devices. Lifting chains are designed to meet industry standards and regulations for load capacity, safety, and performance.
Only alloy steel chain, grade 80 or 100 is to be used for overhead lifting. Alloy steel chain will stretch when over loaded; other types of steel may break without warning. Steel chains slings used for lifting are manufactured specifically for lifting.
The most common reason for damage to chain and chain links stems from improper use, e.g. not complying with the chain's WLL chart. Using a chain incorrectly can cause damage such as cracks, breaks, stretched links or fittings, excessive wear, nicks, gouges and rigid chain links or fittings
Equipment should generally be inspected every three months, or more frequently if subjected to severe conditions.
The steel wire rope has high strength, light weight, stable operation, not easy to break suddenly and reliable operation.
With the development of today's society, the types of chain products are also constantly innovating. The use of chains should be widely used in many industries.
Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor's grip.
