The status of drag chan systems in complex machine systems will be recognized at earliest when a disturbance happens or the system brokes down. Without the well informed selection of robotic cables and cables suitable for drag chains, as well as their incorrect  installation, loss of production and interrumptions of the machine system are predictable. 

The installation of cables in drag chains should be done with greatest care. The below mentioned installation instructions are the result of a practical experience for years with the installation of cables in drag chains as well as the common research with manufacturers and users of drag chain systems.

  1. Only use of cables which are suitable for installation in drag chains You could find this kind of cable in our catalague page:

 

  1. If you occupy the drag chain with cables with a wide variation of the outer diametre, it is recommendable to apply drag chains with seperate areas and stages. If the outer diametre is of ± 20% this is not necessary. If the cables will be installed by occupating several layers, between the layers should be installed seperators.

 

  1. For the dimension of the minimal bending radius of the drag chain lower the cable with the biggest outer diametre is the decisive factor (indication of the minimal bending radius for flexible use in our data sheaths)

 

  1. The distribution of the weight in drag chains should be symmetric. 

 

  1. The cables shouldn’t cross themselves and shouldn’t lie on top of each other.

 

  1. The spin-free installation without forced movement is important. Cables from drums or coils must be the cable should be installed in the extended, uninstalled drag chain, after this the drag chain could be installed on the machine.

 

  1. The complete cross-section of the drag chain should be at most by 80% filled of cables

 

  1. A force guidance of the cables in the drag chain should free movable in the altitude and in the bredth. Cables shouldn’t been fixed in a drag chain or bind together.

 

  1. Cables installed in one layer are more preferable than constructions of in several layers installed cables. If many conductors are necessary, their should be split on several one-layer-installed cables if possible. Due to this bending radius and more bending cycles will be reach.

 

  1. The fix of the cable should be done at both ends with a minimum distance of 30 x cross-section of cable from the final point of the bending movement. The fix should be done over a wide area over the outer sheath. The fleece wrapping shouldn’t be squeezed.
