Constant springs are used to support piping whose movements and/or loading conditions cause too great a variability or too high of a loading condition for a variable spring.
The geometric design of the constant support provides a mathematically constant amount of force exerted throughout the entire range of travel. The force is made constant by a counterbalancing spring assembly.
For an upgraded alternative to the traditional constant spring supports, see our Rilco Cam Roller Constants.
View our Variable & Constant Spring Catalog for complete specs.
The Rilco RCS-80V “Type A” is specially fabricated for mounting on a supporting member by means of attaching a rod into the tapped hole in the constant supports’ top cap.
B/B
The Rilco RCS-80V “Type B” is manufactured with one lug to accommodate attachment to building structure and allow for the use of various types of attachments.
C/C
The Rilco RCS-80V “Type C” is manufactured using two (2) lugs to accommodate attachment to the building structure and allowing for the use of various types of attachments.
D/D
The Rilco RCS-80V “Type D” is designed to lay on top of the beams or structural steel rather than attaching to the structures like the other “Constant Supports”.
E/E
The Rilco RCS-80V “Type E” is the same as the RCS-80V “Type D” except that “Type E” is designed with two (2) brackets that comprise its frame thereby allowing it to rest on the top flange of the structural member.
G/G
The RCS-80V “Type G” is manufactured using opposing constants and a pair of channels welded back-to-back, to form a trapeze assembly.
This Rilco system is designed for use when a pipe is not to be centered on the constant support so that one spring of the trapeze carries a heavier load than the other.
The Rilco RCS-81H “Type A” is specially designed for mounting on a supporting member by means of attaching two rods into the tapped holes in the constant supportÕs top cap.
B/B
The Rilco RCS-81H “Type B” is manufactured with two lugs to accommodate attachment to the building structure and allowing for the use of various types of attachments.
C/C
The Rilco RCS-81H “Type C” is manufactured using two (2) lugs to accommodate attachment to the building structure and allowing for the use of various types of attachments.
E/E
The Rilco RCS-81H “Type E” is similar to the RCS-81H “Type D” except that “Type E” is designed with two (2) brackets welded to the support casing forming a frame which allows the unit to be attached to the top of the structural support.
F/F
The Rilco RCS-81H “Type F Upthrust” is specifically designed to support pipes or equipment from below and is supplied with a base to anchor it to the floor.
