Before testing the winch make sure that it has been correctly
installed.
1) Lower the unloaded rope to the lower loading position by means
of the descent pushbutton, and check that at the end of its travel
three turns of rope remain on the drum.
2) No-load test. Apply a small load (20 kg) and run a complete
up/down cycle.
Test the up, down and emergency stop buttons on the pendant
control, 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.
The operator is responsible for avoiding the above risk.
On completion of testing, compile the test report with the date,
installation check data and signature as well as any other com-
ments (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, 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
(wind or storms) as the load is not guided. Maximum wind
speed must not exceed 12.5 m/s.
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.

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. 8)
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 8, anchor the
ballasts as follows:
Fill the containers with sand each to at least 250 kg.
The specified ballast weights are obtained by means of specific
materials whose specific density does not exceed 1300 kg/m
(e.g. 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.
