Rope fasteners and rope attachments must be checked for the safe condition. We would like to es‐
pecially specify that the wire breaks at such points are often difficult to identify. Other components
of the rope drive such as rope drum or rollers must move freely in the bearings and free from de‐
fects.
4.4.1 Replacement state of hoisting ropes
Hoisting ropes must be replaced immediately if one of the following defects exists in the hoisting
rope.
Even if there is any doubt regarding the further usability of hoisting ropes, it should always be re‐
placed. If required, an expert of the rope manufacturer can be consulted for inspecting the hoisting
rope.
If any particular defects are detected in the hoisting rope, their cause
must be found and the defects must be rectified. Only then a new hoist‐
ing rope should be mounted.

must be shortened so that the replacement condition can be identi‐
fied on time.
