What is the lowest WLL of size 3/8" chain with Grade 70 and size 7/16" chain with Grade 43?

In this scenario, the task is to compare the working load limits (WLL) of two different sizes and grades of chain.

For a 3/8 inch Grade 70 chain, the working load limit is typically around 6,600 pounds. Grade 70 chains are known for their high strength and are often used in heavy-duty applications such as towing and transporting heavy loads.

On the other hand, a 7/16 inch Grade 43 chain has a working load limit that is generally lower than that of the Grade 70 chain, typically around 5,400 pounds for that size. Grade 43 chains are commonly used for lighter applications in comparison to Grade 70.

To determine the lowest WLL among the chains, you compare the values. The WLL of the 3/8 inch Grade 70 chain is higher than that of the 7/16 inch Grade 43 chain, confirming that the lowest working load limit in this scenario is indeed 6,600 pounds from the 3/8 inch Grade 70 chain. This understanding emphasizes the importance of recognizing the differences in chain grades and sizes when selecting them for specific applications.
