Constant Hangers and Constant Supports
Constant hangers and constant supports are used for piping and related components where higher levels of vertical travel occur. Their job is to transfer the working load over the whole travel area while maintaining constancy, i.e., without any considerable deviations. The functional precision of the constant hanger is decisive for the favorable long term behaviour of the components concerned.
The principle of a Constant Hanger
A distinguishing feature of LISEGA constant hangers and constant supports is their unique operating concept. It puts into effect the principle of the parallelogram of forces, which provides the following fundamental advantages:
Absolute constancy based on a principle Load-symmetrical mechanics and structural shape No leverage deflection or momentum effects Directly readable load and travel scales Load adjustment of 40 - 100 % of nominal load Special pre-relaxed springs 10,000 load cycles at constant accuracy Approval by independent authorities
A load range of 70 - 9000 lbs, and a travel range of up to 36 inch are covered as standard. More than 200,000 LISEGA constant hangers and constant supports in use worldwide have proven to be particularly suitable and reliable.

Servo hanger type 17Despite the use of variable spring and constant hangers, piping systems and other components are, under certain conditions, obstructed in their thermal movement by friction or other influences. In such cases servo hangers can be usefully employed. |
