China Lifting Chain

China Lifting Chain

The lifting chain is an indispensable and important picking device for the crane. The length of the chain can be adjusted according to the lifting height of the lifting object, which plays an important role in improving the working efficiency of the crane and expanding the working range of the crane.

Types of Lifting Chains

There are different types of lifting chains available, designed to suit specific load requirements and lifting applications. Grade 80 chains are commonly used for general lifting purposes, offering a good balance between strength and affordability. Grade 100 chains provide higher strength and load-bearing capacity, making them suitable for heavy-duty lifting tasks. Additionally, stainless steel chains are available for applications that require corrosion resistance. The choice of lifting chain depends on factors such as load weight, working conditions, and safety regulations.

Characteristics of Lifting Chains

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.

Working Load Limit (WLL) of Chain

The safety measure was identifying which types of chain are appropriate and strong enough for overhead lifting. Anytime we move or lift a load it is dangerous. Moving a load along the ground has the advantage that the ground is supporting the load. We have to overcome the coefficient of friction to move the load. The chain’s working load limit does not have to match the weight of the load. It needs to be able to handle the tension applied, which is based on the surface that it is being moved over plus some fraction of the weight of the load. This can be calculated using formulas.

If we lift that same load off the ground, we now have to overcome gravity. The chain’s working load limit will have to be of sufficient strength to support the weight of the load plus any additional forces imposed by angles and hitch type(s) used.

Which chain grade should be used for which type of application?

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.

Frequently Asked Question

Do you have any question?

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.
