Load diagram use unsupported - short travels


Important information

Fill weight - Weight of all cables and hoses, including contents (for media hoses) within the e-chain®, typically given [kg/m]

FLG - unsupported e-chain® with straight upper run

FLB - unsupported e-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!


These values are essential for: Finding a suitable e-chain® for your fill weight and travel distance. Identifying the max. load for the selected e-chain®. If you cannot meet your application demands using these parameters, keep in mind these specifications are conservative maximum values.
In individual cases, they can be exceeded by up to 30%. Special solutions are also possible. Please consult igus®

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:
e-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)

Unsupported straight FLG - Fill weights up to 1.5 kg/m

Unsupported with bend FLG - Fill weights up to 1.5 kg/m

Unsupported straight FLG - Fill weights up to 9,0 kg/m

Unsupported with bend FLG - Fill weights up to 9,0 kg/m

Unsupported straight FLG - Fill weights up to 90 kg/m

X = unsupported length FLG[m] | Y = fill weight [kg/m]
S [m] = travel

Unsupported with bend FLG - Fill weights up to 90 kg/m

X = unsupported length FLG[m] | Y = fill weight [kg/m]
S [m] = travel
