Fill weight - Weight of all cables and hoses, including contents (for media hoses) within the energy chain, typically given [kg/m]
FLG - unsupported energy chain cable carriers with straight upper run
FLB - unsupported energy chain with permitted sag
To the right of the FB graph of the diagram, the application is shown in "critical sag", which must be avoided!
The maximum travel - always amounts to 2 x FLG or FLB if the fixed end is in the center of the travel. In this case, the following applies:
energy chain length: Lk = S/2 + K
S = Length of travel
R = Bending radius
H = Nominal clearance height
HF = Required clearance height
K = π * R + "safety"
Add-on for bending radius (K is taken from the data tables of the individual igus® Series)
