Load diagram use unsupported - short travels
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 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 = travel
R = bending radius
H = nominal installation height
HF = required installation height
K = R * π + (2 * T)
(please find K from the dimension sheets of the individual igus® series)
