Customized Lifting 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.

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.

Proper usage of lifting chains is crucial to ensure safe lifting operations and prevent accidents or equipment failure. It is important to select the appropriate lifting chain based on load requirements, working load limits, and industry standards. Regular inspection and maintenance of lifting chains are necessary to identify any signs of wear, damage, or deformation that may affect their strength. Proper training and adherence to safety guidelines are essential for operators and riggers working with lifting chains to minimize risks and ensure optimal performance.

The primary function of lifting chains is to facilitate safe and efficient lifting and rigging operations. They are used to create a secure connection between the load and the lifting device. Lifting chains distribute the load's weight evenly, ensuring stability and reducing the risk of load shifting or accidents. They allow for controlled lifting, lowering, and positioning of heavy loads with precision. Lifting chains provide reliable load-bearing capabilities, enabling the safe movement of objects in various industries, including construction, manufacturing, and logistics.
