3. •What is wire rope?
Wire rope a length of rope made from wires twisted
together as strands (two or more wires concentrically laid
around a center wire). There are three components of a
wire rope include wires, strands, and the core
4. •What is function of wire rope?
Wire ropes are used dynamically for lifting and hoisting in
cranes and elevators, and for transmission of mechanical
power.
•What is the difference between cable and wire rope?
In general, wire rope refers to diameters larger than 10mm.
Sizes smaller than this are designated as cable or cords.
5. APPLICATION
For regular inspection and maintenance of the wire rope
Widely used in various industries
Mining industry, ropeway, lifting equipment, elevator, port machinery, cable
bridge etc.
11. APPLICATION
• 6- Special Fields: Military Industry / Hanging Cable
Diameter of Cable:
• 1-5mm
• Sensor need to be
customized
12. REASONS FOR PERIODIC INSPECTION
ONTHE ROPE
• To decide if the wire rope can safely remain in service and by which latest
time it shall undergo its next periodic inspection
• Action to withdraw the damaged wire rope immediately or within a
specified timeframe.
• If it is intended to carry out a wire rope flaw detection as an element in
periodic inspection, the rope should be subjected to an initial examination
(base trace) as soon as possible in its lifetime to serve as a “datum”
reference point (sometimes referred to as “rope signature”) for future
comparison.
• To be included in the samples of the test taken at office.
13. KEY AREASTHAT REQUIRES CLOSE
INSPECTION
• sections spooling on drum at
point of load being lifted and
other sections suffering greatest
interference
• section(s) entering block
sheave(s) at point of load being
lifted
• sections in direct contact with
compensating sheave,
particularly at points of entry
Single layer spooling
14. KEY AREASTHAT REQUIRES CLOSE
INSPECTION
• crossover zones and those sections
suffering greatest interference
• section where rope enters head
sheave at point of load being lifted
• section(s) entering bottom block
sheave(s) at point of load being
lifted
• point of attachment to crane
Multi-Layer Spooling

21. The common method to determine the wire rope is good
condition is by VISUAL TEST. It is time consuming and solely
rely on the inspector experience and judgement.
Why Magnetic Wire Rope Flaw Detector LGBS600?
Test
Fast and accurate scanning evaluation and diagnosis of various flaws on wire
rope such as internal/external breakage, abrasion, corrosion, loose strands,
wire jumping etc.
Judge
Test data provide a basis judging whether the wire rope should be scrapped or
continue being used.
25. • Terminology
Local Flaw (LF)
- A discontinuity in a rope such as a broken or
damaged wire, a groove wire or any other
damage that degrades the integrity of the
rope.
- The loss of metallic area resulting from LF is
determined independently of the rope
construction. The discard values for loss of
metallic area can be read over a length of 6d
or over a length of 30d from Table C.1.
Loss of Metallic Cross-sectional
Area (LMA)
- Material (mass) loss of the test
point comparing with the maximum
metallic cross-sectional area of the
rope.
