4) The hoist is fitted with a safety which stops travel at the UP (9) and
fully unwound positions (16) to avoid the rope winding on in the
wrong direction.
Do not depend on this safety to stop the winch; release the control
button to stop the winch instead.
When testing is completed, fill in the test report with the date,
installation check and signature (Table 2) along with any other
comments.
The test procedure described above, complete
with no-load (2) and load (3) tests, must be performed
every time the machine is installed.
6. SAFETY WARNINGS AND OPERATING PRECAUTIONS
- 1) Do not lift weights exceeding the hoist s capacity.
- 2) Do not allow anyone to stand underneath
suspended loads.
- 3) Do not attempt to raise loads that are anchored
to the ground (e.g. buried posts, plinths, etc.).
- 4) Make sure that the load is correctly attached to
the hook on the hoist and always close the safety catch
(fig. 4.1, 6).
- 5) If the load requires the attachment of accessories
(belts, ropes, slings, etc.), these must be of a certified
and approved type. The maximum capacity must be
reduced by the weight of these accessories.
- 6) Make sure that no part of the load comes
detached during lifting.
- 7) Make sure that the load rests firmly on the
ground before releasing it from the hook.
- 8) Do not release a suspended load using
accessories that permit instantaneous release or by
cutting the sling.
- 9) Keep hands and other parts of the body well
clear of the drum during operation to avoid the risk of
them getting caught in the winding rope and causing
serious injury.
- 10) Keep hands and other parts of the body well
clear of the counterweight during lifting to avoid the
risk of crushing against the stop lever.
them getting caught in the winding rope and causing
serious injury.
- 11) Do not use the machine in adverse weather
conditions (strong wind or storms) as the load is not
guided.
- 12) The control position and lighting conditions
must ensure complete visibility of the load during its
entire travel.
- 13) Check that all guards are in place.
- 14) During operation check that the rope winds on
correctly, one turn at a time, without slack or overlay
which might damage it. If not, unwind it and rewind it
correctly under tension.
- 15) Make sure that the lifting run is free from
obstacles and make sure that no one can lean out from
intermediate floors.
- 16) Cordon off the ground loading area to prevent
anyone from entering during lifting.
- 17) Keep children away from the hoist.
- 18) Do not allow unauthorised persons access to
the hoist while it is not being used.
- 19) The hoist must not be used for pulling loads
obliquely (more than 5° away from vertical).
- 20) Do not pull the winch on the gantry rails by
means of the electric cables; use the steel handle bar
on the winch frame for this purpose.
- 21) Do not leave a suspended load unattended.
Raise or lower it and unload it.
- 22) When a load is to be raised or lowered, this
must be done in such a way as to minimise dangerous
sideways and vertical movements.
- 23) Do not allow the load to start to spin while it is
being raised or lowered as this could cause the rope to
break.
- 24) Before leaving the hoist unattended, remove
the load, completely wind the rope onto the drum and
disconnect the electric power plug.
- 25) The hoist with the 25-50 m extension (cod.
1199029), the electrical cable must be secured to the
anchoring structure to avoid the risk of breakage.
When operation is resumed after a lengthy period of disuse the entire
machine must be tested under no-load conditions before starting, as
described above (point 2, CAP.5).
7. TESTING AND MAINTENANCE
- Warning: Only carry out maintenance with the machine
switched off, unloaded and disconnected from the mains.
- Repairs must be done by qualified personnel or by IMER Technical
Service.
- Use only IMER original spare parts.
- Check the motor brake every 6/7 days.
- Ensure that the notices and inscriptions on the machine
are prominently displayed and legible.
- Keep the machine clean of dirt.
- Check the operation of the UP and DOWN position limit
switches at the start of each work shift.
- Check the electrical cable at the start of every work
cycle for accidental damage.
7.1 WIRE ROPE
Only use new ropes as specified below, complete with certificate of
conformity and identification.
External diameter :
4 mm
Type :
133 wires (19x7) anti-spin
Direction of lay :
d x
Strand strength :
2160 N/mm
2
Minimum breaking strain :
13 kN
Length :
51 m
Surface treatment : greased
The IMER reference code is given in the spare parts table.
7.1.1 REPLACING THE ROPE (Fig. 4)
The rope must be replaced by a qualified service technician.
Remove the hook (4) by unscrewing bolt (5).
Remove the clamp (1), push on the wedge (2) and extract the
rope from the block (3).
The drum is fitted with a device
which ensures that 2 turns of
rope are always wound on
even when the rope is
unwound to its limit. This stops
the rope attachment from being
overforced.
The rope must be attached in
this way. Completely unwind
the rope. Extract from the
inside of the drum through the
hole and slot.
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 (fig. 4.2), and
pull the rope until the clamp comes into contact with the inner
wall of the drum.
Wind on two complete turns keeping the rope in contact with
the drum (Fig. 4.3).
