Load diagram use unsupported - short travels

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.

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

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)
