Appendix A:
Regulation of overload limiter
CAUTION!
Avoid injuriy by strictly following the
instructions!
a) Verification and/or adjustment of the overload
device on the service lift can only be done by a
qualified person, who must have been instruct-
ed by AVANTI to perform this task.
b) Verification and/or adjustment must be per-
formed under the supervision of the site
foreman or another person authorised by the
manufacturer.
c) One copy of this instruction must be provided
to the personnel and always be available.
d) Alterations/modifications of the service lift
other than those necessary for adjusting the
overload device are not allowed, 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,
especially the prescribed traction hoist wire
rope.
f) The manufacturer of the service lift assumes no
liability for damage due to retrofitting or
alterations to equipment or where non-original
spare parts are used, which have not been
approved by the company in writing. In the
event of violation, the CE certification approval
becomes invalid.
g) The result of the verification/adjustment of the
overload device must be written down in the
“Test report of annual inspection” and signed
by the supervisor. If only adjusting takes place
(no annual inspection) simply fill in point 6.9
and sign.
1 Purpose of this instruction
It is possible that the overload limited inside the
traction hoist of the service lift stops upwards
travel even through the service lift is not overload-
ed.
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.
2 Adjusting instruction
2.1 Preparation
Required tools/material:
- Allen keys, size 2 and 4
1)
- X402P & L502
- Security TX40 - M500
- 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 you bring
the required test load of 300-400kg.
We recommend:
- weighing personnel who may climb into the
lift during the test procedure,
and
- bringing adequate weighed ballast (sand-
bags or similar).
2.2 Exclusion of other causes
Before modifying the overload limiter settings
check if the upwards travel stopping is
caused by other reasons:
a) If the cage is guided by wire ropes or ladder:
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 freely rotate? (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 can hear the “click” sound or feel a
mechanical shock when putting your hand on
the motor fan cover.
In the cases b) or c) have the problem cor-
rected/repaired by a qualified person.
1) With older hoists you may need an allen key size 6.
