personnel. Take all necessary safety precautions.
- Warning! The winch must be tested before use.
Before testing the hoist make sure that it has been correctly installed.
1) Lower the unloaded rope to the lower loading position, and check
that at the end of its travel three turns of rope remain on the drum.
2) No-load test.
down cycle.
Test the up, down and emergency stop buttons, UP limit switch
operation, correct rope winding onto the drum and motor brake
operation.
3) Load test. Load the hoist with its maximum admissible load. Run
the motor brake.
After the test, check the support structure for failure and slippage and
recheck the drum level (use a level as in Fig. 1).
fully raised position (9).
It is however good practice to stop the hoist before the safety
device activates by releasing the UP button.
When the rope is completely unwound, the operator standing near
the machine must check that the rope does not wind onto the drum
in the wrong direction.
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
4.1, 6).
- 5) If the load requires the attachment of accessories
approved type. The maximum capacity must be reduced by
the weight of these accessories.
- 6) Make sure that no part of the load detaches while it
is being lifted.
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
since this can give rise to an elastic counter-reaction of the
entire structure.
- 9) Keep your hands and body well clear of the drum
during operation to avoid them getting caught in the winding
rope; this can result in serious injury.
- 10) Keep your hands and body well clear of the
counterweight during lifting to prevent them being crushed
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
permit a good view of the load throughout its 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 overlaps, as
this can damage it. If it fails to do so, unwind it and rewind it
correctly under tension.

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, Chapter 5).
