Rope and rope attachment - general information
WARNING
Danger due to damaged or twisted ropes!
A twist in the rope impairs its safety and durability.
➢
Therefore always remove twists!
WARNING
Danger due to wire breakage!
With specific applications (e.g. rotation-free rope, constant dead load, repeated holding
position, automatic operation, oscillations, etc.), wire breakage can arise inside the rope,
which is not visible from the outside.
Danger of accidents!
➢
In case of doubt, contact the manufacturer.
WARNING
Danger of load crash!
Further use of a wire rope that is worn out can lead to the rope breaking and a load crash,
resulting in serious injuries or even death.
➢
Check the wire rope regularly.
➢
If a wire rope is worn out, it must be replaced immediately.
➢
Use only original spare parts.
Wire ropes must be checked in accordance with the periods listed in the risk assessment,
although at least once yearly. Depending on the operating conditions and the operational
situation, additional tests may be necessary. Personnel who have been commissioned
with monitoring wire ropes must be familiar with the relevant standards.
A wire rope is worn out once it is no longer possible to be certain of safe continued
operation due to wear. Maintenance, monitoring and the following criteria for discarding
worn wire ropes are described in detail in the standard ISO 4309. Typical damage and
wear conditions of wire ropes are presented in the following.
