We offer seven different configurations for Variable Spring Supports (Type A, B, C, D, E, F, G). Click here for an in-depth explanation of each configuration.
It would not be recommended for a constant spring to be designed for less than 0.1″ for travel. Variable springs can accommodate that travel. The difference in load will be a function of the spring rate.
The “cold” setting of a variable spring support refers to the installed position and the associated load being carried by the support at that time. The “hot” setting refers to the operating position and subsequently the associated load being carried by the support at that time.
Cold Setting Indicated by the White Diamond on a Variable Spring Support
“Spring can” is the general term used to describe either variable or constant spring supports.

A spring hanger is a subset of either variable or constant spring supports that attach directly to structural steel components and are located above the supported member.
Constant Spring Hangers
Variable springs always must have a difference in load between the hot and cold settings. Whereas in constant springs, the load remains consistent. Additionally, in general, constant springs can provide for a higher amount of travel. (Read More in our Technical Bulletin section)

This Webinar will focus on the different types of variable spring supports and big ton variable spring supports. Learn about the special features available, in addition to the design of a variable support. View how the different coil configurations produce a unique response to an applied load and see how a spring assembly is loaded. Discover the basic steps in selecting a hanger design and the step-by-step process used to size a spring for your application. Learn about the different attachments, testing, and installation and maintenance procedures. View examples of failed supports provided by our Field Service Division and learn why they failed and how to prevent it. Gain knowledge of the valuable tips used when deciding to replace or re-calibrate a variable spring support, as well as adjustments, shutdown, and isolation procedures.
