HOIST ROPE
Clean the rope surface before applying
new lubricant. This is particularly
important in environments containing
abrasive particles.
For maximum effect the lubricant is best
applied to the rope where it ‘opens up’ as
it travels over a sheave or winds on the
barrel.
Intervals of lubrication are given for
general guidance. Special applications
and/or experience may show alternative
intervals to be more appropriate. As a
general rule the dressing should be
re ‐ applied at regular intervals and before
the rope shows signs of corrosion or
dryness.
M3 * “Street ‐ Drako Compound” or
similar oil based rope
lubricant with additives for
good penetration, adherence
and corrosion protection.
