The new rope must be mounted
this way.
Completely unwind the rope.
Remove it from inside the drum through the hole and slot. Insert
the new rope in the hole and thread it through the slot in the drum
tube. Tighten the clamp at the end,
leaving about 1 cm of rope free
( g. 4.1), and pull the rope until the
clamp comes into contact with the
inner wall of the drum.
Wind on two complete turns while
keeping the rope in contact with the
drum ( g. 4.2).
On the second turn pass the rope under the hook located inside
the slot in the drum ( g. 4.3).
Tension the rope to ensure good contact with the drum surface.
Wind on the rope in adja-
cent turns, one layer at
a time.
Thread the rope through
the counterweight ( g. 4.4)
and the aluminium sleeve.
Insert the ferrule into the
hole on the hook. Thread
the end of the rope back
through the sleeve and
tighten the ferrule in the
loop formed. About 1 cm of
rope should protrude from
the sleeve.
Pull the rope until all components are tight. Now press the alumi-
nium sleeve using a press or other suitable piece of equipment.
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 inspect the condition of the rope daily and
whenever it is subjected to abnormal strain (twisting, bending,
kinks or abrasion).
Replace the rope when defective (Fig. 15).
Every three months inspect the entire rope carefully and in parti-
cular the ends. Note down 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 HOOK
When using the hook, make sure the load is on its vertical axis.
Misaligned loads can reduce the hook's load rating.
The hook does not require maintenance. Check it from time to
time for deformation and breakage, and replace it if necessary.
Make sure it has its safety tab, if not replace it.
Only use a new hook to replace an old one, with a manufacturer's
certi cate attesting its conformity with the folllowing speci cations:
- load rating: minimum 800 kg;
- nish: painted or galvanised.
7.3 ADJUSTING THE MOTOR BRAKE (Fig. 5)
The electric motor brake is engaged in the event of power supply
failure to the motor.
In the event of reduced braking power, the hoist must be checked
by a skilled maintenance engineer, for adjustments if necessary.
- CAUTION! Before working on the brake, ensure that
the load is removed, the electric power plug is disconnected
and the motor is cool.
7.3.1. Braking adjustment
Remove cap 5 from fan cover 1.
Increased braking: turn locknut 6 gradually counter-clockwise and
check that the brake disengages in descent.
Decreased braking: turn locknut 6 clockwise.
7.3.2. Air gap adjustment
If the brake blocks or in the event of excessive wear, the air gap
should be adjusted as follows.
Remove fan cover 1 and disassemble fan 2.
Loosen the three hex screws 3.
Brake block: turn ringnut 4 clockwise to increase air gap 7 ad
release the brake, checking the gap distance (0.6-0.8 mm).
Brake wear: turn ringnut 4 counter-clockwise to reduce the air
gap, checking the gap distance (0.6-0.8 mm).
Tighten the three hex screws 3 fully down and re t the fan and
fan cover.
To check brake grip, after adjustment, test braking several times
under full load.
7.4 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. Refi ll as required. The oil should be
changed approximately every 2000 hours. Use gear oil with
ISO VG 460 viscosity at 40°C (SAE 90-140).
- Spent oil is classed as special waste and must be di-
sposed of in accordance with current applicable legislation.
7.5 ELECTRICAL SYSTEM
Check the condition of the insulating pendant control case. If it is
damaged replace it with an original IMER spare. Make sure that
the steel cable connecting the pendant control to the electrical
panel is shorter than the electrical cable to protect against pulling.
8. DISMANTLING THE HOIST
Remove all loads from the hook.
Wind the wire rope completely onto the drum. Disconnect the
power plug.
Remove the split pin from the support hinge and remove the
rotating frame.
If a trestle is being used, the carriage must be removed from
the hoist after it has been taken off the guides and before the
counterweight is removed.
9. TRANSPORT AND STORAGE
- Do not leave the installed hoist unattended without rst discon-
necting the electric power supply and winding the rope completely
onto the drum.
When the machine is to be stored for a long period of time, make
sure that it is protected against atmospheric agents.
- During transport protect the machine from shock and crushing
which can adversely affect its functionality and mechanical
strength.
