7.1.2.3 Maintenance tasks for rope drum
1
2
Check the proper rotation of rope drum with and without load.
Pay attention to running sound of rope drum bearings and
check that the rope drum does not touch with machinery end
plates.
Lower the hook to the ground and check the grooves of the
drum. Healthy grooves are smooth and do not have sharp
edges. If any doubt, unwind some more rope from the drum
and compare the used grooves with unused grooves.
Measure the groove wear if needed. Lubricate the drum
surface.

Hoist frame size: VTs, VT1, VT2, VT3
Check the drum axial locking parts (8) for wear. If you notice
any visible marks of wear (max. 2 mm), replace the axial
locking part with new one. Lubricate groove in the drum, in
which the axial locking part (8) is located.
Inspect visually and lubricate:
• The gear rim through the inspection hole (6).
Hoist frame size: VTs, VT1, VT2, VT3
• The drum bearing through the lubrication point (A) or (B)
When lubricating the drum, it is recommended to mark the
starting point in order to know when one rotation is complete.
CAUTION
Only lubricate the greasing points A OR B, but not both. During lubrication,
the drum MUST rotate at least two complete rounds. Do not use excessive
grease, as that may damage the bearings. Approximately two pumps of grease
are sufficient.
CAUTION
Use only the spare parts that are provided by the original manufacturer(s).
7.1.2.4 Drum wear inspection
The rope drum must be replaced if:
Inspection method:
The groove wear is more than allowed.
Measurement, see the following figures and the table. See also
“General Overhaul Instructions”.
A crest of the drum is bent towards groove.
Visual. A sharpened crest is allowed if it is not bent towards the
groove (the sharp area can be removed by filing if the crest wear
dimension is still acceptable after filing).
The wear of the teeth of the drum rim gear is visible.
Visual. Teeth are broken or missing, or they have sharp endings or
are otherwise clearly worn out.
Drum frame size: s, VT1, VT2, VT3: the wear of the drum bearing
running surface is more than allowed.
Measurement. See the figure and the table as follows. See also
“General Overhaul Instructions”.
Drum frame size: s, VT1, VT2, VT3: drum bearing housing has sharp
edges that cannot be filed down, or is otherwise damaged.
Visual.
