12.1 Yearly inspection
Have the entire system, especially the traction
hoist and the safety brake tested by an AVANTI
trained expert at least once annually however
more frequently if required depending on use and
the conditions of use and operation.
The traction hoist and safety brake must be
overhauled at an authorised workshop and
furnished with new certificate for every 250 hours
of operation. (Time counter is found in the power
cabinet (Fig. 20 section 12.1.5).
ATTENTION!
If safety brake has engaged, an expert
must verify the safety of the safety
brake, the wire, and wire attachment.
The tower owner must ensure that the
results of all annual and extraordinary
testing are logged
(Appendix B).
12.1.1 Traction hoist
The traction hoist is largely maintenance free.
Clean only when very dirty. During cleaning always
ensure sufficient air supply.
Annual test:
a) Ensure that no visual defects have appeared.
b) Test emergency descent function
(See Users’s Manual section 7.1)
12.1.2 Safety brake
The safety brake is largely maintenance free.
Clean only when very dirty. Keep free from dirt and
lubricate often (See table 4, section 12.1). Using
too much oil will not harm the equipment or the
gripping function.
Annual test:
a) Test the safety brake stop button.
b) Test the safety brake stop button reset.
c) Release safety wire bottom attachment in tower
and Perform wire acceleration test by hand (See
Installation Manual 5. e) 2) page 54).
12.1.3 Service lift
Annual test:
Inspect the service lift as specified in section 5 of
the User Manual.
12.1.4 Suspension/Wires/Cables
Always keep the wires clean and slightly greasy.
Use ordinary universal lubricating grease, however,
do not use bisulphide-containing lubricants like
Molycote®.
Annual test:
a) Check and replace the respective wire(s) if one
of the following defects are found:
- 8 wire strand breaks or more on a wire
length corresponding to 30 times the wire
diameter (Fig. 17).
- Severe corrosion on the surface or inside.
- Heat damage, evident by the wire colour.
- Reduction of the wire diameter by 5%
or more compare to the nominal wire diam-
eter (Fig. 18)
- Damage on the wire surface – See fig.
19 for most common examples of wire
damage.
These examples do not, however, replace the
relevant provisions laid down by ISO 4309!
b) Check and ensure all wires are mounted at the
top and ground level in accordance with the
mounting instructions (See Installation Manual
section 2.1, 2.3, and 2.6).
c) Power cables
Check and replace the supply and control
cables if the cable jacket or cable connections
are damaged.
d) Wire guide wheels
Ensure wires are led round the guide wheels in
accordance with the fitting instructions (See
Installation Manual section 2.5).
