Always unreel the wire rope in a straight line
(Fig. 37), to prevent it from becoming unusable
because of loops.

– proper connections (thimble, ferrule); on wire
ropes with hook: hook is not bent, safety catch
is in place (Fig. 38);
– the wire rope has no visible damage along its
total length; the fused and tapered end is ac-
cording to Fig. 39.
