Troubleshooting - IMER TR 225 2V Operating, Maintenance, Spare Parts Manual

On the second turn pass the
rope under the hook inside the
drum slot (Fig. 4.4).
Tension the rope for good
contact with the drum surface.
Now wind on the rope in
adjacent turns, one layer at a
time.
Insert the wire rope into the
Fig. 4.3
block (Fig. 4.5).
Pass the rope back through the
counterweight and the block.
Insert the wedge between the
block and the rope.
Pull the rope to tighten all
components. Now lock the rope
with a U-clamp so that the
Fig. 4.4
flat part remains in
contact with the lifting
section of the rope.
Fit the hook to the block
and tighten the bolt and
locknut.
Check that the UP limit
switch operates when
the counterweight
touches the lever.
Run the load test described in paragraph 5 and note down in
Table 2 the fact that the rope has been changed.
7.1.2 PERIODIC CHECKS
Visually check the condition of the rope every
day and whenever it is subjected to abnormal strain
(twisting, bending, kinks or abrasion).
Replace the rope when defective (Fig. 14).
Inspect the entire rope carefully every three months and in
particular the ends; note the results in the chart (Table 2) which
must be kept by the site foreman.
Replace the rope at least once a year.
7.2 ADJUSTING THE MOTOR BRAKE (Fig.5)
The brake is of the no-power engagement type.
If its braking power is reduced a
qualified technician must check the
device and adjust it.
Warning!! Before
servicing the brake make sure
that the winch is not loaded and
that the brake s power supply is
disconnected.
Remove fan cover (A), and adjust
the air gap d between magnet (B)
and brake disk (C) by means of a
feeler gauge.
The gap (d) must be 0.4 mm.
Measurement should be taken at
three points in order to check that
the disc is perfectly parallel to the
IMER INTERNATIONAL S.p.A.
Fig. 4.2
c ou nter wei g ht a nd t he
Fig. 4.5

TR 225 2V
magnet. Slide the feeler gauge lightly backwards and forwards.
If the air gap is too wide, reduce it by tightening nut D with a
ring spanner. Check distance d several times. If the air gap is
too small, increase the it by unscrewing nut D .
Once the air gap has been correctly adjusted, refit cover A .
To check braking power, after carrying out the adjustment,
repeatedly test braking action under full load conditions.
7.3 GEARMOTOR LUBRICATION
- The gearmotor unit must not develop oil leaks. Leaks may
indicate damage to the aluminium casing. In this case, reseal or
replace the casing.
- Check the gearmotor oil level through the
sight glass before every start up or long storage. Refill
as required. The oil should be changed every 2000 hours.
Use gear oil with ISO VG 460 viscosity at 40°C.
- Used oil is classed as special waste. As such, it
must be disposed of in accordance with the established
legislation.
7.4 ELECTRICAL SYSTEM
Check the condition of the pendant control case and cable , if
damaged it should be replaced with the IMER spare part.
8. DISMANTLING
Unload the hook.
Wind the steel rope completely onto the drum. Disconnect the
machine from the mains.
Unscrew the locking handle and extract the telescopic arm.
Remove the split pin on the support pin and extract the rotary
frame.
If a trestle is being used, the hoist unit must be removed from
the carriage after it has been removed from the beam..
9 TRANSPORT AND STORAGE
- Do not leave the installed hoist unattended without having
first wound the rope completely onto the drum and
disconnected the electrical power supply.
When storing the machine for a long period of time, protect it
from aggressive atmospheric agents.
- During transport, protect the machine from blows and crushing
to avoid compromising its functionality and mechanical strength.
10. SCRAPPING
In the event of scrapping, proceed as follows:
a) drain off all oil by means of the relative plug.
b) Separate all plastic and electrical components
(cables, pendant control etc.)
c) Divide all metal components according to type
(steel, aluminium etc.)
On completion of the above, dispose of all components at
authorised waste disposal centres in compliance with current
legislation.
- Respect the environment; certain parts can be
harmful to persons or to the environment.
