Carriers

Design Guidelines
Formulae for the calculation of
the self-supporting length L f
and the chain length L k
and / or the conduit length L ES
If the fixed point is located in the centre of the travel length Ls the
following formulae apply:
L f ≈
L S
––– + t
2
L k/ES ≈
L S
––– + L
2 B
rounded to pitch t
If the fixed point is located outside the
centre of the travel length, the following
applies:
L S
L k/ES ≈ ––– + L B +L
2
V
rounded to pitch t
With variant 2 please consider the selfsupporting
length Lf! (relevant to the
travel length)

Please select the suitable cable carrier taking into account the
required self-supporting length Lf and the additional load qz in
accordance with the diagram.
Hint:
If you are unable to find a suitable cable carrier type for your particular
application on the “unsupported arrangement” diagram we recommend
that you carry out the following checks:
1.
Select a cable carrier with the permitted (desired) sag
(page 2.09)
2.
Provide support for the cable carrier in the unsupported area
(page 2.10)
3.
Select the “sliding in a guide channel” cable carrier system
(page 2.11)
4.
Use a cable carrier in a multi-band arrangement, an arrangement
running inside each other or an arrangement running in an opposite
direction
5. Select a steel cable carrier (see “Steel Cable Carriers” catalogue)
