Constant spring hangers are used on systems where there are large vertical thermal movements, critical stress conditions, or a combination of both. Constant spring hangers are also used at locations to avoid transfer of load from support to support, or to connecting equipment, such as, boiler nozzle or ductwork connections.

The Variable Support is a spring loaded device used for the support of piping and equipment where normal vertical movement is anticipated. Variable Supports are manufactured in five different Travel Series which allow up to ten inches of movement and twenty-five different sizes allowing up to 50,000 pounds of load.

Bergen-Power restraint systems now cover a broader range of load ratings and allow greater flexibility in field adjustment. High precision steel ball bushings and pins are now standard components throughout the line. Also included is a new series of restraint yoke clamps. Bergen-Power hydraulic snubbers have also been improved and are available with options to better suit the different conditions the application requires.
