to 235 V with the hoist operating at full load.
- The electrical supply line must be fitted with both overcurrent
and differential type protection devices and the earth wire must
have the same cross-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 (see 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).
- Connect the machine s plug to a 16 Amp EEC socket with an
IP67 protection factor and tighten up the securing collar.
- The hoist is now ready for testing.
5. TESTING
- Warning!! Testing must be carried out by
qualified personnel only. Take all necessary safety
precautions.
- Warning: the hoist 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 by
pressing the down button, 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 check that the
machine works correctly by running a complete up/down cycle.
Test the up, down and emergency 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. Load the hoist with the maximum allowable load.
Run a complete up/down cycle to test the stability of the supports
and the motor brake.
After the test, check the support structure for failure and
slippage and recheck the horizontal alignment of the drum (using
a level as shown in fig. 1).
4) The hoist is fitted with a safety which stops travel at the UP (9) and
fully unwound positions (17) 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.
- IMPORTANT! Limit switch activation can occur either
due to incorrect working height or due to other problems
which may prejudice correct hoist functioning. After the limit
switch has been activated, the hoist installation and
components must be checked (rope, drum, shaft etc.)
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) Never lift loads exceeding the capacity of the
elevator.
- 2) Never allow persons to remain below suspended
loads.
- 3) Never try to lift loads anchored to the ground
(e.g. embedded posts, plinths, etch.).
- 4) Ensure that the load is securely connected to
the elevator hook and also close the safety catch (ref.6
fig. 4.1).
- 5) If the load requires accessories to be attached
to be hooked up, these must be certified and approved
(harnesses, ropes, slings, etc.). The weight of these
accessories must be subtracted from the maximum
capacity.
- 6) Ensure that no part of the load protrudes during
the lifting phases.
- 7) Before releasing the load, ensure that it is in a
stable position.
