HOIST CABLE LUBRICATION
The hoist cable is a wire rope and should be cleaned and lubricated every 50 hours of normal
operation, and more frequently when used in dirty or corrosive environments. Whenever the
rope is dirty or dry, it should be serviced. The rope should be cleaned with solvent and com-
pressed air or solvent and rags. A wire brush may be used for difficult areas.
The recommended lubricant is AMOVIS #2-X. It should be sprayed or dripped onto the rope
where it is bent, as it passes over the tip sheave, as it is spooling onto the hoist. Use an appro-
priate ladder or steps to access the tip sheave. Wrap rags around the wire rope behind the
sheave and swab the excess oil that is carried along on the rope. Always wear heavy leather
gloves when handling wire rope.
CABLE WEDGE (FLANGE MOUNT) INSTALLATION & INSPECTION
The following steps will assure that the wire rope (aka hoist rope, hoist cable, or load line) winds
smoothly and evenly on the hoist and will yield greater safety and longer rope life.
If the cable is not sufficiently compact during the initial assembly phase when it is loaded, it may
become caught up in the turns below, and damaged.
1. Position rope spool such that rope will wind from the top of the spool, to the top of the hoist
drum. Winding from the bottom of the spool will introduce a reverse bend and may introduce
torque into the rope.
2. Never “pull loops through,” as this will introduce a kink in the rope and severely shorten ef-
fective service life. If excess rope accumulates on the floor, straighten it to remove loops &
eliminate tension without introducing torque or a kink.
3. Introduce the cable end into slot positioned on the drum, and then into pocket “A.”
4. Fold the cable around wedge “B.”
5. Secure the cable and wedge in the slot by pulling firmly.
