Wire ropes must be installed with the required tightening torque. 

 

 

 

A  visible contusion of the  wire ropes positively  indicates that the  wire rope clips  have  been tightened to 

the required tightening torque. 

 

 

 

Wire ropes that have not been damaged can be used again, but the threads and the saddle, in particular, 

must be inspected for any damage. 

 

 

 

After the first load application the tightening torque has to be checked and if 

not fulfilled adjusted to the required value.
