viii) Particular care should be taken in the inspection of non-rotation rope.
ix) Wire rope removed from service due to defects should be plainly marked
or identified as being unfit for further use on load carrying devices.
e. Upon receipt of wire ropes, whether they arrive in coil form or on reels, it is
advisable to examine, and if necessary remove, the outer protective
wrapping. This may have become wet during transit and, if left on the rope
local corrosion will appear in course of time. Ropes should be stored in a dry
atmosphere and preferably off the floor, on well seasoned timber.
f. Rope delivered in reel form should have the reel jacked up to turn freely, so
that the rope can be carried straight away from the reel. Provision should be
made to stop reel rotation by using a braking device, however simple.
g. When rope is delivered in coil form, it should be rolled along a smooth
surface, like a hoop, away from the end of the rope, and protected from
unnecessary bending and abrasion.
h. When rope cannot be stretched out straight, it should be arranged in a long
narrow “U” or series of “U’s” with as wide a radius for the turn of the “U” as
possible.
i. When handling wire rope, it should be manipulated so that its natural twisting
action will not cause it to kink.
j. A replacement rope must be of the same type and specification as the
original fitted to the rig by the manufacturer, and of the correct safe working
load.
k. Care should be taken when installing ropes on winding drums to ensure that
there is even tension of the new rope being pulled round the system, that
sharp bends are avoided and that the rope is kept clear of dirt and abrasive
materials.
l. Rope should be kept tightly and evenly wound on the drums.
m. When the rope is feeding onto the drum it should not be touched by hand.
n. In order to prevent crushing the rope where a drum divider is used, there
should not be more than four turns on the working section when the tool is at
the deepest point.
o. Overruns should be avoided by correct winch operation.
p. The rope should be firmly fastened in the drum with set-screws, or a suitable
clamp, and three full turns of the rope should be kept on the drum at all
times.
q. Every rope should be thoroughly lubricated with the correct wire rope
dressing as it is installed, and kept similarly coated throughout its life.
