Fall Arrest Device - Avanti SHARK L AECO Original Instructions Manual

13.4.3 Fall arrest device

The fall arrest device shall be maintained according
to maintenance planning (please see sections 13.1 or 13.2).
Relevant maintenance instructions are provided to each
person during the training. These maintenance inspections
must be only carried out by a certified technician.
If fall arrest device has engaged due to a dynamic fall,
a certified technician must verify the safety of the fall
arrest device, the wire rope, and wire rope fastenings.
After FAD has engaged, if the FAD damper has
STOP
moved downwards, the FAD unit must be replaced
by a certified technician.
13.4.4 Traction, safety and guiding wire ropes
Carry out the following inspections and adjust if
necessary:
1. Inspect all the wire ropes along their entire length.
2. Pay special attention to the wire rope ends, parts of the
wire ropes running over sheaves and wire ropes under
frictional wear by external components.
3. When inspecting the wire ropes, consider the following
points:
type and number of wire breaks, position and time sequence
of wire breaks, decrease of the wire rope diameter
during operation, corrosion, abrasion, deformation, influence
of heat, and operating time.
4. Check that the traction and safety wire ropes are fed
correctly around the 2 wire rope guide wheels.
5. Check that the wire rope ends are coiled separately under
the bottom platform and tied with at least 3 cable ties.
6. Check that the guiding wire rope tensioning system is
correctly installed and that the wire rope locks and fixes are
properly fastened.
7. Check that the compression spring on the safety wire rope
is correctly installed and that the wire rope locks are properly
fastened.
8. Check that the counterweight on the traction wire rope is
properly fastened. The traction wire rope coil and
counterweight shall be able to rotate freely. Do not attach
them to a fixed part.
9. Check that the guiding wire ropes are correctly tensioned.
Record any visible change of the condition of the wire
ropes on the appropriate Inspection Appendix, and
monitor closely throughout time.
13.4.4.1 Cleaning
1. Open the top lift hatch to access the wire ropes from
inside the service lift.
2. Use a cloth to wipe off the old grease from the wire ropes.
3. Close the top lift hatch and ascend the service lift 1 or 2 m.
4. Repeat steps 1 to 3 until the entire length of the wire ropes
is clean.
!
Always keep the traction, safety and guiding wire
ropes clean and slightly greasy.
!
Only use mechanical means to clean the dirty wire
ropes, i.e. a cloth or a hand brush. Do not use
solvents or other detergents.

13.4.4.2 Lubrication
If the distance between platforms is more than 20 m
perform the following procedure:
1. Ascend the service lift 20 m.
2. Open the top lift hatch.
3. Through the top lift hatch and with a spray can,
apply lubricant on the wire ropes.
4. Close the top lift hatch and ascend the service
lift 3.2 or 6.5 ft (1 or 2 m).
5. Repeat steps 1 to 4 until the entire length of the
wire ropes is lubricated.
6. Finally, perform two complete ascends and
descends in order to distribute the new lubricant
evenly along the wire ropes.
If the distance between platforms is equal or less
than 20 m perform the following procedure:
1. A first person ascends in the service lift several
meters so that the wire ropes are accessible from
the platform.
2. From the platform and with a spray can, a second
person applies lubricant on the wire ropes.
3. Both persons ascend in the service lift to the next
platform.
4. One person egresses to the next platform.
5. Repeat steps 1 to 4 on each platform until the
entire length of the wire ropes is lubricated.
6. Perform two complete ascends and descends in
order to distribute the new lubricant evenly along the
wire ropes.
!
Only use specialised wire rope lubricants. Do not use
lubricants based on lithium soap grease or bitumen.
Do not use disulphide-containing lubricants like
Molycote ®. Apply lubricant using a spray can, brush,
drip applicator or pressurized device.
Pay special attention to sections of the wire rope
where dehydration or denaturation of the lubricant
can be seen.
Re-lubricate the wire ropes before they show signs of
corrosion or run dry, and taking in mind that:
• A poor lubrication leads to corrosion and to a
quick wear of components.
• An excessive lubrication leads to dirt agglomeration on
the wire rope surface. As a result, this can lead to quick
wear of wire rope, sheaves and drum.
• A correct lubrication keeps the efficiency factor
of the wire rope, protects against corrosion,
helps to elongate their lifetime significantly and
ensures a safe operation.
13.4.4.3 Measuring of the wire rope diameter
When measuring the diameter of the wire ropes,
use a digital calliper with broad measuring faces.
