– It is also recommended to:
a) avoid overloading the hoist;
b) stop the lifting movement before the limit switch trips
since it should only be used in case of emergency;
c) check that the voltage does not decrease excessively
during the start-up phase (this may prevent the brake
from opening);
d) make sure that the cable does not completely
unwind; at least 2 turns of the cable must remain on
the drum to avoid damage due to the direct action of
the load on the clamp that attaches the cable. The
cable wound on the hoist drum has a length that is
greater than the maximum foreseen use height.
e) (using the special set screw) place the rotation shaft
of the cable winder drum in a horizontal position to
guarantee that the cable will be correctly wound on
the drum.
f) The cable maximum winding diameter must
guarantee a free space on the sides of the drum
equal to 1.5 times the cable diameter.
Note: The manufacturer declines all responsibility
for injury to persons or damage to property as a
result of non-compliance with the above-mentioned
standards.
9. STORAGE
In the event of on elevator mounted externally, no
longer in use, it is advisable to dismount the unit from
the supporting structure and store in a dry place.
In the case of on elevator which is being used internally,
it is advisable to disconnect it electrically and protect
the equipment from dust.
10. MAINTENANCE
The machine must be periodically inspected (on a
six-month or yearly basis) to check the general use
conditions (e.g. leaking grease, condition of electric
power supply cables and machine control components,
condition of the support structure, etc.).
In particular:
– Check several times that the start/stop (end of run)
button and the hand holding switch gear are all
functioning correctly.
– Periodically check the condiction of the power supply
cable: if this has been crushed or the protective lining
damaged, substitute it immediately. If the elevator is
used mostly externally, substitute the power supply
cables every 3–4 years.
– Periodically check the condition of the steel rope,
and should any trace of wear or breakage of threads
be noticed, immediately revert back to a Tractel
®
authorized service centre.
– The cables must be checked every three months if
there are any breaks in the elementary wires, or if
they are twisted, smashed, bent, if knots have formed
or if there is any other serious deterioration (heavy
rust formation) or if heavily worn immediately revert
back to a Tractel
®
authorized service centre.
For the good working of the down limit switch check that
the cable rewinding occurs correctly.
The substitute steel rope must be of supplied by
Tractel
®
– it may not be even a few metres longer. Non-
compliance could subject the motor to overloading and
possible burning out and nullify any claims in terms of
the Guarantee.
– The above-mentioned inspections must be reported
on a special chart (see appendix page), indicating the
date of the inspection and the signature of the tester.
See App D – Periodic inspections
– The braking system must be checked every six
months and, in any case, each time that, during normal
machine use, the load does not stop immediately.
– The distance between the brake disk and
electromagnets is adjusted using the set nut located
at the end of the motor shaft.
– It must range between 0.3-0.5 mm.
The cable, hook and braking system register
must be replaced by a TRACTEL
®
service center.
11. REPAIRS
Repairs must be performed at a TRACTEL
®
service
centre.
Any repairs out by unauthorised persons, substitution
of parts not designed for this machine or substitution by
non-genuine ports, will nullify the Guarantee.
12. REQUEST FOR SPARE PARTS
The request for spare parts must be submitted to a
TRACTEL
®
service centre or to a dealer.
It must include the following:
a) hoist model and serial number;
