When measuring chain sag, which side needs to be taut?

In the process of measuring chain sag, it is essential for one side of the chain to be taut to obtain an accurate measurement. The taut side is crucial because it ensures that the measurement reflects the actual working condition of the chain under load. A slack chain can cause misleading results, as any play or looseness will distort the sag measurement. By focusing on the taut side, you can accurately assess the amount of sag, which is important for the proper functioning and longevity of the chain and the equipment it supports.

This method emphasizes the need for a consistent and controlled environment when measuring chain parameters, as variations in tension can lead to premature wear or failure. Proper chain tension is vital for efficient operation; therefore, understanding how to measure it correctly contributes to maintenance practices that enhance equipment performance.
