Constant Effort Supports

 VBMCS Constant Effort Support          

Constant Effort Supports are used to support pipework or equipment with an essentially constant supporting effort during what may be large vertical movement. Where the change in supporting effort which occurs when using variable effort supports is unacceptable, or where the amount of travel provided by variable effort supports is insufficient, constant effort supports should be specified.

High-temperature steam lines in power stations and flow lines on oil production platforms are examples of situations where large relative movement between piping and the supporting structure make the use of Constant Effort Supports essential.

To view the Catalogue pages for Constant Effort Supports please select Metric or Imperial version. 



We offer 11 standard support types:

HS Horizontal type – single point suspension  Type HS
HD Horizontal type – double point suspension  Type HD
VS Vertical type – single point suspension  Type VS
VD Vertical type – double point suspension  Type VD
VIS Vertical inverted type – single point suspension  C4-15 VIS TS2

Vertical inverted type – double point suspension

 C4-15 VID TS2
HBM Horizontal base-mounted  Type HBM
HBMCS Horizontal base-mounted compression seat  Type HBMCS
VBM Vertical base-mounted  Type VBM
VBMCS Vertical base-mounted compression seat  Type VBMCS
VIBM Vertical inverted base mounted  C4-15 VIBM

The support designation gives the support frame size and spring size:

For the suspended types, five styles of top suspension are available, namely TS1, TS2, TS3, TS4 and TS5.


Infinitely-variable Locking Device          

Infinitely Variable Locking Device

Infinitely Variable Locking/Balancing Device. Every unit is sent to site locked in the D.T.S. (Despatched To Site) position shown on the general arrangement drawing for the contract. The locking mechanism comprises two locking rods which run the full length of the spring housing. The hanger is locked and becomes a rigid support by restraining the spring compression plate as shown in the picture. The locking device being constructed from two threaded members operates in an infinitely variable number of positions and is securely attached to the support for future re-use, regardless of pipework position.
