Method B: Mount the reel on an unreeling
stand (Figure 4-24). It is then unwound in the
same manner as described in Method A. In
this case, however, greater care must be
exercised to keep the rope under tension
sufficient to prevent the accumulation of slack
- a condition that will cause the rope to drop
below the lower reel head.
Method C: Hold the end of the rope while the
reel itself is rolled along the ground. With
this procedure the rope will pay off properly;
however, the end being held will travel in the
direction the reel is being rolled. As the
difference between the diameter of the reel
head and the diameter of the wound rope
increases, the speed of travel will increase.
When re-reeling wire rope from a horizontally
supported reel to a drum, it is preferable for the
rope to travel from the top of the reel to the top
of the drum (Figure 4-25). Re-reeling in this
manner will avoid putting a reverse bend in the
rope as it is being installed. If a rope is installed
inducing a reverse bend, it may cause the rope to
become livelier and, consequently, harder to
handle.
When unwinding wire rope from a coil, there are
two suggested methods for carrying out this
procedure in a proper manner:
-

Figure 4-25. Horizontal Re-reeling
Method A: Place the coil on a vertical unreel-
ing stand. The stand consists of a base with a
fixed vertical shaft. On this shaft there is a
swift, consisting of a plate with inclined
pins positioned so that the coil may be placed
over them. The whole swift and coil then
rotate as the rope is pulled off. This method
is particularly effective when the rope is to be
wound on a drum.
