technician.
c) One copy of this instruction must be provided
to the personnel and must always be available.
d) Alterations/modifications of the service lift
other than those necessary for adjusting the
overload device are not permitted, unless the
manufacturer has agreed in writing.
e) AVANTI assumes no liability for damage due to
retrofitting/alterations to equipment or where
non-original spare parts are used, which have
not been approved by the company in writing.
This particularly applies to the specified
traction hoist wire rope.

Where other causes can be excluded by following
the instructions of section 2.2, the overload limiter
must be adjusted according to section 3.
2 Instructions for adjustment
2.1 Preparation
Tools/materials required:
- Security TX40 - M508
- Ballast for applying the test load;
Note! Before driving to the service lift
make sure that the service lift can be loaded with
the permissible test load, i.e. "safe working
load" + weight of power cable + 25%.
IMPORTANT!
Before leaving for the tower, make sure
that you have the required test load of
300-400kg.
We recommend:
- weighing personnel who may climb into the
lift during the test procedure,
and
- taking suitable weighed ballast (sandbags
or similar).
2.2 Exclusion of other causes
Before modifying the overload limiter settings
check if the upwards travel stop is caused
by other reasons:
a) Check for obstructions on the guiding
device(s) and remove them.
b) Check that the wire rope moves freely at
the diverter or similar:
- Is the rope blocked/pinched at any point?
- Do the pulleys rotate freely? (check with the
service lift set to ground with no load on the
ropes, or by a person from outside the cage,
when going up and down.)
c) When starting, does the primary brake
open? You should hear a "click" or feel a
mechanical shock when putting your hand on
the motor fan cover.
In the case of b) or c), the problem must be
corrected/repaired by a certified
technician.
