14000 OPERATOR MANUAL SETUP AND INSTALLATION
Winding Wire Rope onto Drum
See Drum and Lagging Chart in Capacity Chart Manual for
correct size of drum laggings, if used.
See Wire Rope Specifications Chart in Capacity Chart
Manual for correct type, size, and amount of wire rope to be
installed on load drums.
See Boom Assembly Drawing at end of this section for
correct type, size, and amount of wire rope to be installed on
boom hoist drum.
1. Carefully inspect drums and all rope guides, rollers, and
sheaves for defects that can cause wire rope to wear or
be cut. If defects cannot be fixed, replace faulty parts.
2. Apply tension to wire rope as it is wound slowly onto
drum.
First wrap must be tight against drum flange for
approximately three-fourths of drum diameter (see
Figure 4-51
).
3. Tap adjacent wraps against each other with a soft metal
or wooden mallet.
Use extreme care not to put twists or turns in wire rope;
allow rope to assume its natural lay.
CAUTION!
Wire Rope Damage!
Voids or spaced wraps in first layer (see View B,
Figure 4-51
) will permit movement and a wedging action
with subsequent layers. Wedging action will cause
crushing and abrasion of wire rope.
Never allow wire rope to “cross wind” on drums.
