Steel Wire Rope Sling Inspection – Part 1
Wire ropes are playing the key role in the lifting activities in any industry. Wires are the basic building blocks of a steel wire rope. They lay around a “center” in a specified pattern in one or more layers to form a strand. The strands are helically laid together around a center, typically some type of core, to form a wire rope.
The strands provide all the tensile strength of a fiber core rope and over 90% of the strength of a typical 6-strand wire rope with an independent wire rope core.
All wire ropes will wear out eventually
and gradually lose work capability throughout their service life. That’s why
periodic inspections are critical. Applicable industry standards such as ASME B30.2
for overhead and gantry cranes or federal regulations such as OSHA refer to
specific inspection criteria for varied applications. The respective country
specific requirements to be ensured.
The Purposes for Inspection of Wire
Ropes
Regular inspection of wire rope and equipment
should be performed for three good reasons as below,
It reveals the rope’s condition and indicates
the need for replacement.
It can indicate if you’re using the most
suitable type of rope.
It makes possible the discovery and correction of faults in equipment or operation that can cause costly accelerated rope wear.
How Often
All wire rope sling should be
thoroughly inspected at regular intervals and with respect to local regulations.
The longer it has been in service or the more severe the service, the more
thoroughly and frequently it should be inspected. Be sure to maintain records
of each inspection.
Inspection by a Qualified Person
Inspections should be carried out by a person who has learned through special training or practical experience what to look for and who knows how to judge the importance of any abnormal conditions they may discover. It is the inspector’s responsibility to obtain and follow the proper inspection criteria for each application inspected. Color coding is one of the best practice followed in industry.
“Inspect Your Wire Rope Regularly
Inspection should be performed by a person
with special training or practical experience”
