Istruction Manual for Operation and Maintenance SPX-960:
4.9.3 WIRE ROPE INSPECTION
The wire ropes must be kept under constant control for
wear. Regarding wire ropes refer to section 5.2 in Chapter
5 “Maintenance”.
The wire rope supervisor and tester must be qualifi ed to under-
stand the causes of possible breakage or damage to the rope:
he must be able to understand if the rope is in good operating
condition or if it needs to be replaced. (Fig. 51).
Small grooves cause wire rope deformations and excessive
contact between the rope elements (strands and core): this
may jeopardize wire rope performance and duration. The wire
rope duration is also affected
by groove wear. For instance, if the groove is excessively sco-
red or deformed, the wire rope is more likely to get worn.
DANGER
The wire rope is wound on parts which are specifi cally
sized according to the rope diameter. For this reason, it
is not recommended (due to more rapid wear) and it is
dangerous to use different wire rope diameters from those
indicated by the manufacturer.
