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

c o u n t e r we i g h t a n d t h e

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
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

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.
