Instructions on the use

Transport and handling

Steel ropes are transported safely secured on reels or coils. Unloading should be done carefully; the rope should not have any contact with sharp edges or surface.
After handling, the rope should be carefully examined in order to discover possible packaging damage. If the packaging is damaged, the rope should be applied to another reel. The other possibility would be to change the outer wrapper.
Steel rope should be stored in a clean and dry place indoors; outdoor storage is not recommended due to the possible rusting in case of rain or condensation. In its storage, steel rope should not be affected by corrosive substances, chemical fumes or dust. Temperature should not be higher than 100 ºC nor so high as to damage the packaging.

Uncoiling

correct Uncoiling the rope carelessly will create loops, which can result in kinks if loops are pulled tight. Thereby the wire rope can be damaged and no longer of use. By uncoiling or coiling the rope slowly and meanwhile keeping it tight, the damage could be avoided.
If one end of the rope wound on the reel is fixed with the other one being uncoiled, the rope is likely to twist (360° either to left or right). This happens due to the inner tensions that were created when the rope was wound before transportation. Therefore the rope has to be uncoiled on flat and clean surface, any twists should be removed and the rope straightened. Only then can the rope be formed into another coil or wound on another reel.
If the rope is to be wound on reel in more layers, it has to be properly wound in one circle next to another.

Lubrication

Steel ropes are delivered lubricated (Elaskon lubricant is highly recommended) or dry, depending on customer's wishes and technical specifications. Even though some users would avoid the use of lubricated ropes, lubricants prolong the working life of the rope (up to 50 %). Especially steel ropes that are frequently unwound and rewound on a drum have longer working life if lubricated. Steel rope should always be cleaned before lubrication.
Examination and discard criteria
Special care should be taken in case of broken wires, grease, signs of wear, corrosion and other imperfections.
The rope should be discarded if its diameter is reduced to 90 % of the nominal diameter.
According to the Order on machinery safety, the rope design factor is 5:1. If the maximum capacity is up to 5 tons (before the rope breaks, according to manufacturer's data), the maximum load that can be applied to the rope system is up to 1 ton.
If single wires are broken, the following steps should be taken: the wire rope should be discarded if 10 (or more) % of wires in a length equivalent to six diameters are broken and if more than 20 % of wires in a length equivalent to ten diameters are broken.
Example:  steel core wire rope 6×37 with a diameter of 10 mm has 222 wires. If more than 22 wires are broken in the length of 6 cm, it should be promptly discarded.

The wire rope must be removed if:

  • it is completely broken
  • it is deformed (e.g. node)
  • its diameter is reduced to 80 % of the nominal diameter due to being exposed to external strain.
  • it has signs of strong corrosion.

The results of inspection and examination should be documented.
