Configuration guidelines | Selecting the cable carrier
Determining the bending radius KR The chapter for the selected cable carrier contains the sizes of the available bending radius. The selection of the bending radius depends on the cables used. The information from the cable manufacturer regarding the dynamically moving minimum bending radius have to be taken into account for this.
The selected bending radius of the cable carrier has to be equal to or greater than the largest minimum bending radius of the cables to be installed. We recommend using KABELSCHLEPP ® cables which were specially designed for use in cable carriers.

1.4 Determining the cable carrier length L k for simple linear travel It is practical to place the fixed bracket connection at the center of the travel path. This provides the shortest cable track length between fixed and moving ends and therefore the most economical cable carrier and cable length. Of course your cable carrier can also be installed with a fixed bracket outside of the center of the travel path. The calcu- lation follows these examples:
For fixed bracket at the center of travel path L S , the following applies for cable carrier length L k :
The length of carrier in bend L B is determined according to the selected cable carrier type:

The calculated values can be found in the tables in the respective individual chapters. Plastic cable carriers L B = KR x π + 2 x t Steel cable carriers L B = KR x π + 4 x t QUANTUM ® series L B = KR x π + 12 x t TKR series L B = KR x π + 2 x t
