- The choice of the power chain system must be made in accordance with the requirements of the cables necessary. Note: It is to be reccomended if possible not to use cables of multilayer construction, i.e. > 25 crores, but spread the necessary number of cores over several cables.
- The minimum permissable bending radii of the cables must be adhered to. (Information will be found in the Technical Data of our Catalogue under bending radius for flexible use).
- The cables must be laid without twisting in the power chain system, i.e. never unwind from drums or coils from one end, but unroll the cables and if necessary lay them out or suspend them. It is recommended that cables for this application should only be taken directly from drums. Warning: The method of manufacture mean that the rinting runs in a gentle spiral around the cable. It cannot therefore be used as an indicatior of the twist-free straightening of the cable. When the cable is being drawn in, the chains should be laid out longitudinally and than loaded with the cables in the working position.
- The cables must lie loosely next to each other in the chain stays. As far as possible they should be arranged individually, separately from each other by spaces or in separate holders in the neutral zone of the chain. The free space for the cables in the chain stay should be at least 10% of the cable diameter. Arranging cables one above the other without using separators should be avoided. Note: With a vertically suspended chain arrangement more free space must be provided in the chain stay, because the cables become extended in operation. After a short period of operation the length adjustment of the cables must be checked and if necessary corrected.
- The cables must not to be attached or tied together in the chain.
- If a power chain should break the cables must also be replaced, because damage due to excessive stretching cannot be ruled out.
