Spooling Wire Rope on Drums
Care must be exercised when installing wire rope on the winch drum. Improper spooling
can. result in rope damage through crushing, kinking, dog- legs, abrasion and cutting.
Poorly installed wire rope will also adversely affect the operating characteristics of the
machine by causing uneven application of force and motion. This, in turn, can cause
premature fatiguing and failure of the rope.
Thoroughly inspect and clean the winch before proceeding with the installation. Check the
lagging and drum flanges for cracks, breaks and excessive wear. Deformed or outsized
drum and excessive undercutting at the base of the flange also indicate that repair or
replacement of the drum is necessary.
Check the bearings for excessive wear and play. After correcting any defects revealed by
the inspection and determining that the winch is in good operating condition, spool the wire
rope as follows:
Correct Spooling
Incorrect Spooling
Mount the cable shipping reel (1) vertically on jacks or a suitable supporting structure, with
a pipe or bar through the reel center. The cable should be drawn from the top of the reel, as
shown, in order to avoid reverse bending as it is spooled onto the drum (2).
If cable is wound from the storage reel onto the drum, the reel should be rotated in the
same direction as the hoist.
