Constant hangers and constant supports

Characteristic: Load/travel diagram with the acceptable tolerance limits in recognized guidelines (e.g. VGB-R 510 L, KTA 3205.3). The buckling-resistant design, production and special thermal treatment guarantee a linearly unchangeable force-travel-curve of the springs.

Nominal load: F_N (Maximum load of the constant hanger)
Required load: F_S
Set average load: F_{actual, average}
Condition for the average setting: (|F_S- F_{actual, average}|)/F_S ≤ 0.02
Nominal travel: s_N
Required travel: s_S
Travel reserve: s_{R 1"}
