How do I check the load setting of a spring support?

November 2, 2010

To check the load setting, examine the position of the bottom of the load indicator with respect to the scale on the spring's tag. Read from the bottom of the load indicator to determine position. Next, look at the size of the spring located on the tag. Then, refer to the appropriate load and travel table (Constant Load & Travel Table or Variable Load and Travel Table) to determine the respective spring rate and the “0” load (minimum working range load). Multiply the spring rate by the position value and add that to the “0” load value.

What is meant by “rod take-out” in spring supports?

The rod take out (RTO)is the amount of space between the upper attachment point and the lower attachment point of spring hanger assembly.
