BASIC FIELD MANUAL
rope must be bent back and reversed to direction in which
kink was formed. A kink cannot be straightened by pulling
the rope taut; this merely unlays the rope.
f. Loads must not be applied suddenly. This puts exces-
sive strain on rope.
g. Avoid using wire rope on sheaves or drums which are
too small, and avoid reverse bends or sudden changes in
direction of pull. Either of these conditions causes severe
strain and broken wires in strands and weakens rope.
h. It is best to wind only a single layer of rope on drums;
however, if necessary to wind more layers, second layer is
wound on grooves formed by first, except that once in each
turn rope crosses over two sections of first layer. Third layer
is parallel to first layer and wound on grooves of second,
except at crossovers. In all cases when it is expected to wind
a second layer, the turns of first layer must be wound together
tightly to prevent possible binding.
i. Ropes should not be pulled around small trees or flat
surfaces. This causes strands to spread.
j. Distance between hoisting drum and first sheave should
be not less than 15 feet per foot of drum width. Distances
shorter than this cause excessive rope abrasion.
k. When removing wire rope from reel or coil, reel or coil
must rotate as the rope unwinds. Attempts to unwind rope
from stationary coils will result in kinking.
(1) A correct method for unreeling wire rope is to mount
reel on a shaft supported at each end. Rope is then pulled
off, permitting reel to rotate. When spooling wire rope from
reel to drum, rope should travel from top of reel to top of
drum, or from bottom of reel to bottom of drum. This pre-
vents reverse bends which make rope difficult to handle.
(2) To uncoil wire rope, end is held stationary while coil
is rolled out on ground. This method prevents kinks.
1. When coiling wire rope loose as it comes from drum,
determine lay of rope; if left lay, coil to left (counterclock-
wise), or if right lay, coil to right (clockwise). When fin-
ished, ends of rope should be tied to coil, and top or end should
be marked to aid in uncoiling.
m. To wind wire rope on reel or drum, the following rule
is convenient to determine proper starting flange; the left
