How to store natural fiber rope
Store it in an open-sided crate blocked up several inches from the floor, and allow
plenty of
air circulation in the storage room. If coiled correctly, the rope coil can be suspended
from hooks or pegs, allowing maximum
air circulation.
most common method of rope construction
three-strand twisted. Twisted construction ropes tend to untwist under load. The heavier
the load, the greater the tendency to spin out. Braided
ropes do not spin.
the tension at which a rope will tear under a load.
Breaking strength
dividing the breaking strength by a safety factor .
The safe working load
environmental factors that may compromise the integrity of hoisting rope
Dirt picked up by rope during normal use causes wear of the individual fibers.
▪ Natural fiber ropes pick up moisture easily, hastening decay due to rot and mildew.
Even without the presence of rot,
, manila and nylon ropes are not as strong when wet. A wet rope is also more apt to kink.
▪ Frozen wet rope cannot be used. It must be thawed out and thoroughly dried. Frozen
fibers crack if bent around a
sheave , greatly reducing the strength of the rope.
how to uncoil rope
always uncoil it from the center in the opposite direction from the lay - usually
counterclockwise, Unwinding rope incorrectly produces loops or hackles.
how are rope ends prevented from unraveling
whipping
inspect a rope for
▪ Broken yarns or strands
▪ Spots or sections of rot or mildew
▪ Abrasion and wear
▪ Cuts or burns
▪ Dirt between fibers
▪ Water soaking and freezing
what are knots made up of
▪ The working end - which is the end of the rope that will be used for tying the knot
▪ The running end - which is the other end of the rope, used for lifting or hoisting
▪ The standing part - which is the long portion used for hoisting or securing; the portion
of the rope that is acted upon
▪ The bight - which is formed by bending the rope back to itself, keeping the sides
parallel (a knot considered "in the
bight" or "on a bight" means a bight of line that is itself being used to make a knot)
▪ A loop, which is formed by crossing the sides of a bight
