4. CONNECTION TO THE ELECTRICAL MAINS
Make sure the mains voltage matches that given on the machine
rating plate and that it is between 210V and 235V with the hoist
operating under full load.
- The power supply line must be equipped with overcurrent
and differential-type protection devices and the earth wire must
have the same section as the live wire. The wires must be
sized taking into account the operating currents and the length
of the line, to avoid excessive voltage drops (ref. Table 1).
Do not use extension leads wound onto drums.
- The power supply cable must be suitable for frequent handling
and must have an abrasion-resistant sleeve (e.g. H07RN-F
type).
- Connect the plug from the machine to a 16A EEC socket with
IP67 protection rating and tighten the mechanical retainer ring
nut.
- The hoist is now ready for the first test run.
5. TEST INSTRUCTIONS
- Important. Testing must be performed by expert
and skilled personnel, taking all the necessary
precautions to ensure safety.
- Important. The test must be carried out before
using the hoist.
Before testing the hoist, carefully check that it has been
correctly installed.
1) Lower the unloaded rope to the lower loading position by
pressing the down button, and check that at the end of its
travel at least three turns of rope remain on the drum.
2) No-load test. Apply a small load (20 kg) and check that the
machine works correctly by doing a complete up/down cycle.
Test the up, down and stop buttons and check that the up limit
switch and the electric motor brake work correctly and that the
cable winds correctly onto the drum.
3) Load test. This must be performed by applying the maximum
load permissible for the hoist. Do a complete up and down run
to check the hoist anchorings and the electric motor braking
device.
After the test, check the support structures for possible giving
or settling and recheck the horizontal alignment of the drum
(with a level).
4) The hoist is fitted with a safety device which stops travel in
the fully raised position (ref. 9).
It is a good rule to stop the hoist before the safety device is
tripped, by releasing the relative command button.
When the rope is fully unwound, the operator standing near
the machine must check that the rope does not wind in the
wrong direction onto the drum.
At the end of testing, 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 capacity of the
hoist.
- 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 the load is properly attached to
hoist hook and always close the safety catch.
- 5) If the load requires accessories (belts, ropes,
slings, etc.) to be hooked, they must be of certified and
approved type. The weight of these accessories must be
subtracted from the maximum hoist capacity.
- 6) Make sure no part of the load comes out during
lifting.
- 7) Make sure the load rests firmly on the ground
before releasing it from the hook.

Before resuming work after an extended idle period (e.g.
overnight) the hoist must be tested by doing a no-load cycle
(as described in point 2, CHAP. 5).
7. HOIST FRAME INSTALLATION (fig. 7)
After ensuring that the support surfaces can withstand the
stresses indicated in fig. 7, proceed as follows..
Position the middle tube (1) vertically, checking that when the
hoist is in the loading position the rotation locking lever (11, fig.
1) is inserted in a groove in the locking plate, located below the
lower pivot.
Using the nuts and bolts provided with the support, fit the left
and right feet (2) at the base of the middle tube then fit the
upper (3) and lower (4) tie rods. Join the two feet with the
joining rabbet (5).
Make sure the nuts and bolts are tight.
Check that the support is perfectly upright (e.g. using a spirit
level), if necessary adjusting by placing metal shims under the
base of the support.
Secure the middle tube by means of two M12 anchor bolts on
the foot (position T).
To prevent the support from tipping over during operation, anchor
it in one of the following ways:
