Wire cables
Wire cables should be checked for
the following defects:

cables, or more than 10 ruptured
wires for cable-laid rope
• damage or severe wear to the
d
s
cable connector or cable-end
connector
• high number or ruptured wires
Checking the wire cables has to
include looking for signs of slipping
between the cable and the ferrule.
Wire cables must be kept away
from any aggressive material to avoid
corrosion; acids, alkaline fl uids etc.
Crane hooks must have a large radius.
Sharp-edged hooks or hooks with
small cross section, and therefore
small radii, can lead to unacceptable
damage of the wire cables.
