3. Wire rope
 A wire rope is an important item of engineering
materials in mining & many other engineering
industries.
 Wire ropes are made from steel wires of plain carbon
steel having high tensile strength.

4. Types of wire rope
 On the basis of operation of wire rope:-
a. Stationary wire rope
b. Running wire rope.
 On the basis of construction of wire rope:-
a. Stranded wire rope
b. Non-stranded wire rope

5. Testing of wire rope
 Tensile test-The specified length of wire is subjected
to a stretching force in a testing machine until the
rope may break
 Torsion test-A specified length of wire rope is
stretched and its both ends are gripped into vice.
One of each is twisted until is is break.
 Bending test-One of the wire is fixed in vice with
specially rounded laws and the wire bend towards
and backward through 180° over the jaws until
break.

6.  Wrapping test- in wrapping test the wire is heated
and one end is wrapped tightly at other usually for
eight turns.
 Looking test-The end of short piece are taken one on
each hand & stress generate on the rope by rounding
in forward & backward direction.

7. Application of wire rope
 In open cast mines
1-Dipper shovel ropes
2-Dragline hoist rope
3-Dozer
 In underground mines :-
1-Winding ropes
2-Haulage rope
3- Coal cutting machine
