UP limit switch operation, correct rope winding onto the drum and
motor brake operation.
3) Load test. Load the winch with its maximum admissible load. Run
a complete up/down cycle to test the stability of the supports, gantry
and the motor brake.
After the test, check the support structure for failure and slippage and
recheck the drum level.
4) The winch is fitted with a safety device which stops travel at the UP
limit position (ref.9, fig.1).
Do not depend on this safety to stop the winch; release the control
button to stop the winch instead.
On completion of testing, compile the test report with the date,
installation check data and signature as well as any other comments
(Tab. 2).
In case of new installations and after every service, repeat
the no-load (2) and load (3) tests described above.
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, ref.
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.
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.

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, CHAPT.5).
7. GANTRY SUPPORT: INSTALLATION AND USE (Fig. 7)
The gantry comprises two Ø 48 mm tubular supports and an NPU 65
rail on which the winch wheels slide.
The gantry features a facility for counterweight ballasts comprising
two enclosures (C) with padlock closure, a base unit (D) (height 30
cm) to be fixed by means of brackets and screws, 2 connecting beams
(E), damper end stop (A) and winch fixing bracket (B) with end stop.
7.1 INSTALLATION
On completion of assembly as shown in figure 7, anchor the ballasts
as follows:
Fill the containers with sand each to at least 150 kg.
The specified ballast weights are obtained by means of specific
materials whose specific density does not exceed 1300 kg/m
dry sand).
To avoid tampering with ballasts, the containers must be closed with
lids and padlocked.
Never use makeshift systems such as bags of cement or bricks simply
placed on the gantry frame as these cannot be sufficiently anchored
to the frame.
Always ensure complete efficiency of the ballasts before using the
winch; check for any damage that may affect operation.
Remove the winch from the gantry rails before disassembling the gantry
and emptying the ballasts.
8. TESTING AND MAINTENANCE
Repairs must be done by qualified personnel or by IMER Technical
Service.

24) Before leaving the hoist unattended, remove the load,
completely wind the rope onto the drum and disconnect
the electric power plug.
Position the ballast containers on the ground.
The use of liquids is expressly prohibited.
Do not fit the winch onto the gantry before fitting the
ballasts.
Warning! Only carry out maintenance with the machine
switched off, unloaded and disconnected from the mains.
- Use only IMER original spare parts.
- Check the motor brake every 6/7 days.
- Ensure that the notices and inscriptions on the machine
- Keep the machine clean.
- Check the operation of the UP limit switch at the start of
Check the electrical cables at the start of every work cycle
for accidental damage.
