Wire Rope1.Selection of Wire Rope Refer to GB8918-2006"Steel
wire ropes for important purposes"and GB/T20018-2006"Steel wire
ropes for general purposes"on how to select from different
constructions of wire rope.Please also refer to this section of our
product catalogue in selecting wire rope.We suggest choosing equal
lay steel wire rope,Compacted wire rope for general usage.The
technical parameters such as lifting load,safety coefficient,and
the lifting capacity of the lifting eauipment should be taken into
conside ration when selecting the strenath class of wire rope.Do
not blindly choose hiah strenath and high breaking force wire
rope,this may compromise results. 2.Installation of Wire Rope
Unwinding: Put a piece of iron tube through the reel or coil of
wire rope,then install the reel onto a dedicated carrier.Keep the
wire rope parallel to the ground and turn to unwind. The
arrangement of wire rope on the reel:The winding direction of wire
rope on the reel Should depend on the lay direction of wire rope
from left to right for right-lay wire rope,from right to left for
left-lay wire rope. Wind the wire rope neatly onto the reel without
the wire rope overlapping each other. Cutting:
For wire rope with relatively high residual stress,use a soft iron
wire to tie the rope 10-20mm from the cutting point.The length of
the soft iron wire should be 1-4 times that of rope diameter.Then
cut with cutting tool. 3.Maintenance and Inspection of Steel Wire
Rope Operarion: In operation, the wire rope should be
in steady speed,never overload,and never shock load a wire rope.
Maintenance: Lubricant is applied to the wires and
strands of a wire rope when manufactured.This lubricant is depleted
when the rope is in service.And various nocuous matters will stick
to the surface of the rope.These will cause abrasion between wire
rope and the block,and rusting of the rope.lt is important to clean
and replace lubricant to the wire rope periodically.
Record of inspection: wire rope should be inspected
regularly,and all the records should be kept carefully.Other than
cleaning and adding lubricant,the inspection should include
checking the following: abrasion of wire rope,condition of broken
wires,and corrosion.Also check the condition of metal parts such as
pulley groove,loading ring,hook,etc.Pay special attention and check
for external and internal broken wires in the fixed end of wire
rope,and the section of wire rope that passes through pulley blocks
and drums. 4.Contact between Wire Rope and Pulley Groove
The appropriate contact between pulley groove and wire rope
is indicated in (figure 1).If the pulley groove is too wide(figure
2),the wire rope and its metal core are subiect to more broken
wires owing to fatigue. lf the pulley groove is too narrowf(igure
3),the wire rope will be worn seriously. The ratio between the
radius of pulley groove and that of the wre rope should
be:R/d=0.525~0.550. Why Us
Jiangsu Langshan Wire Rope Co.,Ltd.is a company changed over from
the former Nantong Wire Rope(Group)Co.,Ltd.that is a
