E-NORMpro Wire rope PVC coated 3 x 4 mm Ro.130m(250 x 80)

Wire rope galvanized/transparent sheathed, roll goods

- Consisting of best wire rope with nominal strength 1770 N/mm²,
- Low-twist and stress-free
- According to EN 12385-4

Low-twist and stress-free wire ropes and their advantages
1. The strands of the ropes are preformed. Cut ropes maintain their position without the need to
tie the side at the interface.
2. Since all strands are uniformly stretched, the load is evenly distributed among all individual wires in the rope.
3. The ropes have only a slight tendency to form pitches.
4. The unloaded wire rope is stress-free because the wires have no preload. The ropes therefore show little tendency to twist under
load.
5. The ropes are characterized by quite particularly high flexibility.
6. Low-twist and tension-free ropes have a significantly increased service life compared to normal wire ropes.

Calculation of the load-bearing capacity:
The load-bearing capacity of the wire ropes is calculated from the minimum breaking load. This is
divided by the safety factor prescribed for the particular application.


Supporting force = **Minimum breaking load
6 (safety factor)


*Construction:
A wire rope consists of a number of strands, which in turn consist of a number of wires. Furthermore, fiber inserts (Fe) are integrated to support the strands, to reduce
vibrations in the wire rope and to hold lubricants.
c. E.g.: 5 x 7 + 1 Fe -> 5 strands with 7 wires each and 1 fiber core


Important note:
The wire ropes may only be used in accordance with the accident prevention regulations and the related EN standards, e.g. 12385-4, 13414 and 15020.

Caution: Remove plastic sheathing at
these points before crimping!
