Replacing the cable

NOTICE
► Have the state of wear of the cable evaluated only by competent specialized personnel.
► Cable must be inspected as specified by DIN 15020/ Sheet 2.
► Replace the cable immediately if 6 load-bearing wires are broken over a length of 66 mm or
13 load-bearing wires are broken over a length of 330 mm.
► The cable must not be spliced.
The cable must be replaced if it is no longer able to ensure operational safety. The operational safety
of steel cables can be assessed according to the following criteria:
■ Number of broken wires and type of breakage
■ Wire break at the end of the cable
■ Position of wire break
■ Frequency of wire break
■ Broken wire strands
■ Reduced cable diameter by 15 % due to structural change
■ Reduced cable diameter by 10 % or more due to abrasion or corrosion
■ Loss of elasticity
■ Internal and external abrasion
■ Internal and external corrosion
■ Cable deformation, bunching, knots, crushing, notching, kinks
■ Wear on the steel cable due to exposure to heat
■ Excessive stretching
■ Severe damage due to corrosion
■ The number of visible wire breaks on a specified stretch of rope as defined by UNI ISO 4309
All inspections must take the above criteria into account. If cable damage is attributed to more than
one of the above factors, there will be a variety of effects, which should be checked by the personnel
responsible. These should then decide, after careful examination, whether the cable needs to be re-
placed or can be re-used.
In all cases, the technician responsible for cable monitoring must determine whether the damage is
due to an equipment failure; if this is the case, he/she will set out the measures necessary for repair-
ing the fault before a new cable is installed.
