This document discusses non-stranded wire ropes used in mining. It begins by defining wire ropes and distinguishing them from cables and cords based on diameter. It then classifies wire ropes into two main types: stranded ropes which are built of strands consisting of twisted wires, and non-stranded ropes where the layers are coiled without strands. The document focuses on types of non-stranded locked coil ropes, describing their construction and properties. It provides details on full lock coil, half lock coil, and Z-lock and X-lock varieties, and discusses their applications in mining operations and advantages like strength, fatigue resistance, and service life.

3. In stricter senses, the term "wire rope" refers to a diameter larger
than 3/8 inch (9.52 mm), with smaller gauges designated cable or
cords. It is an important item of engineering material in mining and
many other engineering industries.

WIRE ROPE

4. TYPES :
There are many classification of wire ropes based
on different properties, but it’s broadly classified as:
1. Stranded Ropes
2. Non-stranded Ropes

5. Wire Ropes
Stranded Ropes
A stranded rope is built up of
strands and each strand
consists of a number of
concentrically twisted wires
laid in the form of a helix
round a central steel wire.
Non-stranded
Ropes
In non-stranded rope, mainly the
layers are coiled in a locked fashion
and no such strands is there as in
stranded ropes.

6. An example of this category is the locked coil ropes.

9. Full Lock Coil
The compacted and densely concentrated metallic cross section of the FLC track rope
guarantees a higher breaking load whilst the outer interlocking “Z”-shaped layers give the
rope a smoother profile, reducing fatigue caused by the interface between rope and
sheaves and rollers.

11. FEATURES
Parallel core
Sacrificial coating for corrosion resistance
Diameter: 30 – 74mm
MBL: 853 – 6906kN

12. Full Lock Coil, Z-Lock for deep shaft mining is a high strength,
low stretch, stable, non-rotating rope. With its characteristic Z
wires, designed to prevent unlocking, its smooth outer surface
makes it highly compatible with sheave linings (drum and
Koepe). Z-Lock ropes can be designed and manufactured to be
compatible with specific drum grooves.

(A powerful, high strength rope for deep shaft mining applications.)

13. ADVANTAGES
Precision engineering
Rope is made to optimise performance and safety, enhance
operating efficiencies, reduce costs and extend service life.
High fatigue performance
Engineered for overall performance, the tensile strength of
FLC’s interlocking Z wires is key to this rope’s superior fatigue
resistance.
Long service life
With its characteristic steel Z wires, designed to prevent
unlocking, the FLC Z-Lock has an exceptionally smooth outer
surface making it highly compatible with sheave linings and
resistant to friction, abrasion and fatigue
Cost effective
High ductility wires minimise the occurrence of internal wire breaks
caused by dynamic stresses, improve performance and extend service
life.

16. The outer layer of interconnecting Z
profile wires give the Full Lock Coil, Z-
Lock rope an extremely smooth outer
surface that is suitable for Koepe
friction winders and drum winders.
APPLICATIONS

17. FULL LOCK COIL TRACK ROPE
A fatigue resistant track rope for aerial transportation
and open pit mining.
Full Lock Coil, Z-Lock for aerial transportation and open pit
mining is a high strength, low stretch, stable, non-rotating rope.
Engineered to ensure the best resistance to wear, the high fill
factor of the core guarantees that the rope will remain round
under load, preventing abnormal wear and ensuring smooth
rolling and transportation of carriers.

19. HALF LOCK COIL X-LOCK
The precision guidance rope with long service
life.
Half Lock Coil, X-Lock is a non-rotating, low
stretch, high strength rope that is designed for
use as a guide rope in deep mine shafts. The
smooth and closed outer surface reduces
friction and increases resistance to the
ingress of dirt particles

20. High service life
HLC X-Lock’s unique structure, with interlocking X and O profile wires, provides a smooth outer surface
that reduces friction and is resistant to the ingress of damaging dust and debris particles.
Easy installation
The non-rotating structure of HLC X-Lock make installation straightforward.
Precision engineering
Rope is made to optimise performance and operating efficiencies, reduce costs and extend service life.
Cost effective
High ductility wires minimise the occurrence of internal wire breaks, improving performance and
extending service life.
