MAINTENANCE AND LUBRICATION
CABLE LUBRICATION METHODS
GENERAL We are covering the more commonly used
methods of lubricating cable (wire rope). For special
cable lubrication problems consult the cable manufac-
turer.
HOT APPLICATION A heated bath is placed in the
path of the wire rope, and the rope is passed through
the hot lubrication over sheaves and a center guide
wheel. Hot oils or greases have excellent penetrating
qualities and upon cooling have high adhesive and film
strength around each wire.
CONTINUOUS BATH Run an operating rope through
a specially constructed casing that has been packed
with swabbing and loaded with lubricant. This affords
continuous lubrication.
DRIPPING A container can be placed above the
sheave, so that the rope can be lubricated by opening
a spigot. Sheaves are the best location for lubricating
operating wire ropes, because the wires and strands
open somewhat as they bend along the groove.
POURING Lubricant can be poured on. The rope
should be lightly loaded and run slowly while being lu-
bricated.
SWABBING AND PAINTING Lubricant can be
swabbed on with rags, or painted on with a brush. Both
are quick methods which can be made part of the op-
erating routine.
SPRAYING A light lubricant containing solvents can
be applied to a wire rope by a properly directed spray
nozzle.
AEROSOL SPRAYING Installations requiring only
small amounts of lubricants, or only occasional appli-
cations, may find the new aerosol cans of lubricant
useful. They are available from several lubricant man-
ufacturers.
