Winding Wire Rope onto Drum
1. Remove the wire rope from the shipping reel:
a. Mount the wire rope shipping reel (1, Figure 4-56
)
on a shaft (2) supported at both ends by jacks (3) or
blocks.
b. Provide a brake at the shipping reel so that the wire
rope can be wound tightly on the drum.
c. Avoid a reverse bend when winding the wire rope
onto the drum: wind from the top of the reel to the
top of drum (upper view) or from the bottom of the
reel to the bottom of the drum (lower view).
d. Avoid dragging the wire rope in the dirt or around
objects that can scrape, nick, cut, or crush the wire
rope.
2. Carefully inspect the drums and all rope guides, rollers,
and sheaves for defects that can cause the wire rope to
wear or be cut. If defects cannot be fixed, replace the
faulty parts.
3. Apply tension to the wire rope as it is wound slowly onto
the drum.
a. The first wrap of wire rope must be tight against the
drum flange for the approximately three-fourths of
the drum diameter (View A, Figure 4-57
).
b. Tap the adjacent wraps against each other with a
soft metal or wooden mallet as the wire rope is
spooled onto the drum.
c. Use extreme care not to put twists or turns in the
wire rope. Allow the rope to assume its natural lay.
CAUTION
Avoid Wire Rope Damage
The shipping reel must rotate when the wire rope is
unwound.
Attempting to remove the wire rope from a stationary reel
can result in a kinked wire rope, and the wire rope will be
ruined.

CAUTION
Avoid Wire Rope Damage
Voids or spaced wraps (View B, Figure 4-57) in the first
layer will permit movement and a wedging action with the
subsequent layers. Crushing and abrasion of the wire
rope will occur.
Never allow the wire rope to “cross-wind” on the drum.
